By their very nature, construction sites are risky places to work. Reflecting this, 40% of people in the construction industry think an accident is “inevitable” on their sites. To deliver effective health and safety, the Health and Safety Executive says that leadership is essential. It highlights three essential principles:

Strong and active leadership from the top

visible, active commitment from the board
establishing effective ‘downward’ communication systems and management structures
integration of good health and safety management with business decisions.

Worker involvement

engaging the workforce in the promotion and achievement of safe and healthy conditions
effective ‘upward’ communication
providing high quality training.

Assessment and review

identifying and managing health and safety risks
accessing (and following) competent advice
monitoring, reporting and reviewing performance.

With that in mind, what could and should a site safety checklist for glazing contractors cover?

Here are 10 areas to consider. For each item, assess how they apply to your business and the practices you can implement to ensure risks are dealt with sensibly, responsibly and proportionately.

Wearing Personal Protective Equipment (PPE)

Requiring workers to wear appropriate PPE such as safety glasses, gloves, hard hats, steel-toed boots and cut-resistant gloves will help to protect them from injury.

Handling glass

Using items such as glass cutters, suction cups and glazing tools help to minimise the risks of working with glass. Remember the importance of maintaining these tools so they are robust and reliable.

Working at height

When glazing at height, consider the safety protocols needed to minimise the risk of falls, as well as any additional equipment that might be required to keep workers safe.

Organising the worksite

Encourage workers to maintain a tidy, organised worksite that’s free of clutter. This will reduce trip hazards – and may help to speed up installation because everything will have a designated space.

Lifting and carrying

Ensure workers are clear about proper lifting techniques that will minimise back strains and other injuries. Consider too whether additional lifting equipment is needed for heavier items.

Watching the weather

The notorious British weather means workers will sometimes need to work in adverse conditions. Understand the additional measures that will be needed to protect workers in poor conditions, especially the wind and rain when moving glazed units will be trickier.

Maintaining health and hygiene

Regular hand washing will minimise the risk of irritation and contamination from minute pieces of glass. Assess too if there are any risks with any of the other materials used on site, such as adhesives or sealants, and how you can mitigate those risks.

Communicating effectively

Miscommunication or misunderstandings can cause accidents, so clear communication between workers is key. As well as the way workers communicate with each other, consider the way you communicate the health and safety checklist. Use clear language, images and practical examples to keep things clear and easy to understand.

Working with other contractors

On commercial sites, it’s likely that workers will be working alongside other contractors. Consider how you will work safely with these other trades and any additional safety measures you might have to put in place.

Being prepared

Make sure there is a well-stocked first aid kit on site at all times and that workers are trained in basic first aid so they can take prompt action if needed. Finally, remember that health and safety checklists are live documents. Make sure you keep yours up-to-date with the latest safety regulations and industry standards. Regular refresher training will also be important to ensure health and safety remains a key priority for everyone in your team. When you take leadership on health and safety, you are helping to meet your legal obligations as a business. More importantly, you are protecting your team.

Last year, Part L of Building Regulations, which covers the conservation of fuel and power, was significantly amended. It was the first step towards the Future Homes Standard, which aims to make sure all new homes built from 2025 produce around 75% less carbon emissions, and, ultimately, support the commitment to achieve net zero by 2050.

The new Part L of Building Regulations came into force on 15 June 2022. However, to give the industry time to adapt to the changes, the regulations had a twelve-month grace period. The changes did not apply in relation to building work where a building notice or an initial notice had been given to, or full plans deposited with, a local authority before 15 June 2022. However, this only applied if the building work started before 15 June 2023.

Now that 15 June 2023 has passed, all building work will need to comply with the new regulations without exception or exemption.

What do the new Part L regulations say?

There are different requirements depending on whether it’s a new building or an existing one. New buildings have more demanding requirements because builders have more control over more of the elements of the building. On existing dwellings, the regulations are slightly less demanding.

In brief, the new regulations are as follows:

In new dwellings, windows and glazed doors (defined as where more than 60% of the door is glazed), must meet a notional U value of 1.2 W/(m²K). You can think of ‘notional’ as being a ‘recipe’ approach that means if all other standards are also met, the building will comply.

In existing dwellings, replacement windows or glazed doors must have a U value of 1.4 W/(m²K).

What do you need to watch out for now the Part L grace period has ended?

It is important to note that not all window and door systems were able to comply with the new regulations when they changed on 15 June 2022. Several systems have only been upgraded in recent months. Therefore, it is essential to check with your systems supplier that your system complies with the new Part L regulations.

Rest assured that here at Mercury Glazing we only manufacture systems that comply with the new Part L.

A reminder of the updated reporting requirements for Part L

The way you need to show evidence of compliance to Part L has changed as part of the updates.

For dwellings, a Building Regulations England Part L (BREL) report is needed, along with photographs taken at each build stage to prove that the building work meets regulatory standards.

For buildings other than dwellings, two Building Regulations UK Part L (BRUKL) reports are now required, one for the ‘design’ and one covering ‘as built’.¹

Note the requirement for photographic evidence – if you aren’t already doing this, you will need start taking photographs of installations at every stage. The regulations say.

Photographs should be digital and of sufficient quality and high enough resolution to allow a qualitative audit of the subject detail. Close-up photographs may be needed where a long shot image provides insufficient detail. More than one image of each detail may be needed. Geo-location should be enabled to confirm the location, date and time of each image. Each image file name should include a plot number and detail reference according to the numbers used in paragraph B7. For example, Plot 1 eaves detail would be P1/3b.²

Where to go for advice about Part L

If you have questions about the new Part L requirements around thermal efficiency, here at Mercury Glazing we are happy to help. We can provide as much or as little technical support as you need with all your installations. From consultation to installation, our team will be with you every step of the way – it’s the Mercury difference!

In contemporary architecture, if the aim is to achieve a space that feels and looks modern, more often than not aluminium is considered the go-to material for windows. If we look at glazing trends of recent years, aluminium windows have been perpetually popular, both in the private and public sectors – and, so far, 2023 seems to be no different.

One of the big reasons for this sustained popularity is its adaptability as a material, which has meant that it has been able to deliver on our modern efficiency criteria whilst maintaining its flexibility with regards to our changing aesthetic tastes.

So, even though aluminium windows have been a constant in the modern architectural landscape for well over a century now, the industry is far from growing stale; on the contrary, each new year brings with it new ideas, keeping the world of glazing innovative and fresh.

Here’s a rundown of the current aluminium window design trends, as noticed by our team of experts here at Mercury.

Minimalism: A Lesson in Less

There was a time when aluminium windows were associated with bulky, chunky designs, but those days are long gone. Recent times have seen the frames of aluminium windows become ever slimmer; often making them the most elegant and sleek frames available on the market.

This less-is-more approach works in today’s climate for several reasons: they’re lighter, and therefore easier to install; their production requires less in the way of raw materials; they create a more spacious feel to your home’s interior – and they look great too, of course.

Another core benefit of slimmed-down frames is that less aluminium equals better thermal performance, as glass is a more energy-efficient material than aluminium.

Colours

For the past few years, there has been a trend towards making window frames bright and colourful; and while this is still true, there is a growing demand for more neutral tones at the moment, particularly blacks and browns.

Black is seldom used as a prevailing colour in architecture, which makes it a perfect counterpoint for your window frames. Dark-coloured windows often become nearly invisible when combined with glass when viewed from the outside. Having such a clean and clear contrast enables the openings of your house to really stand out – with the added bonus of being a colour that complements all other shades and materials.

In keeping with this movement towards more traditional palettes, brown window frames have also seen a recent surge in demand. For fairly obvious reasons, they are the perfect choice for those who wish to bridge the gap between the functionality of contemporary design and the aesthetic associations of heritage pieces.

Size

One of the many ways in which aluminium has superiority over its competitors in the glazing industry is in the fact that the frames can be made much larger without compromising the window’s structural integrity. Floor-to-ceiling windows are a definite big-hitter for designers of modern-feeling properties and are the perfect solution for those who have a view they are keen to show off or for those whose main priority is to maximise the levels of natural light indoors.

Having larger windows may be more costly in the first instance, but they can sometimes also reduce utility bills and help create a more airy and spacious living area – food for thought for any home-improvement plan.

Shapes

When we want to add a touch of individual flare to our windows, it might be worthwhile considering a change to their shape. While it may not be anything new, differently-shaped windows have been on the rise in recent years – and aluminium just happens to be the perfect material for this type of customisation.

Privacy

Designing a home is a process of contradictions and the windows exemplify this process perfectly. On the one hand, we want our properties to feel welcoming and open; on the other, we want them to feel separated from the outside world and for them to provide a place of privacy and security. Luckily, with modern glazing, you can easily achieve the best of both worlds.

Tinting and colouring on glass is one of the most effective ways of obscuring the view of your indoor spaces from outside. Modern iterations of this technology even allow natural light to filter through, meaning your privacy doesn’t equate to an increase in your utility bills.

Textures and patterns in the glass are another popular way of nullifying the potential of prying eyes. Texturing comes in all sorts of different configurations and adds a point of interest to your glazing design scheme.

Integrated Blinds

If covered windows are a must-have but space is at a premium, integrated blinds might just be the solution you were looking for. These types of blinds are built into the frames of the windows and they allow for maximum control over the amount of light and privacy in our homes – all while adding a touch of modern elegance to our windows and saving valuable space.

Automated Features

Sometimes, our instinct to incorporate modern technologies into as much as possible can seem a little excessive; in the case of windows, though, this evolution makes perfect sense.

Being able to control windows remotely not only offers control and convenience but peace of mind too – a truth that will be all-too familiar to those of us who have lost sleep over the possibility of leaving a window ajar.

It might seem strange to suggest that a feature powered by electricity might increase your window’s energy efficiency, but the ability to monitor them from anywhere means that you can ensure your home is always working to its optimal thermal efficiency. In the UK, where the weather can shift seasons in a day, more and more people are seeing the value of this kind of control.

Finishes and Effects

Aluminium is known for its crisp, clean and smooth finish, but it can also be made to emulate the look of other materials. Frames can be made with a faux wood grain finish, for example, making them often acceptable for use on properties with listed features.

A Century of Modernity

It’s strange to think that a material can exist in the popular imagination for so long as something that evokes a sense of modernity, but aluminium has done exactly that. Gone are the days though when the trade-off for stylish aluminium window frames was condensation build-up and a cold room – modern aluminium glazing is truly a thermal marvel these days offering the same benefits of competing materials with the added style for which aluminium has always set the benchmark.

A staggering 40% of global energy consumption is currently used in the built trade, more than in the agricultural and food sector – at around 30% – and, according to some figures, roughly equivalent to the amount used by the world’s militaries.

Suffice to say, then, that construction will play a major role in accomplishing our 2050 target of reaching Net Zero – and, when we look at the industry today, we see one in a period of innovation and progress, busy tackling the twin issues of the climate crisis and an ever-growing population.

Glazing is at the forefront of this change and from the production of the raw materials to the installation of the eventual products in our homes, we are constantly finding ways to improve performance and reduce the industry’s negative ecological impact. Here’s just some of the ways in which glazing is contributing to this global effort.

Eco Architecture: Mutualism in Practice

The word efficiency has multiple uses. In business, it has historically been synonymous with increasing productivity while cutting costs; in today’s climate-conscious world, the cost part of that association has been widened to include the cost to our lived environment.

So, these days, when we talk of a thing’s efficiency, we think of the materials we use and the practices that have gone into their production; the energy needed to create and transport these materials; their life-cycle; and the impact that our choice of location will have on the environment.

In an ecological sense, the benefits of utilising green building techniques hardly needs explaining, but it would be a mistake to think of the choice purely along these lines: properties designed with lower-impact practices will have smaller maintenance outgoings and tend to have a higher asset value, making them a sensible investment too.

Windows in a Green World

Before we look at the component parts of a window and how they fit in to this shift towards Net Zero, we should look at the units themselves and how central they are to the energy efficiency of our homes.

All told, it’s a widely-documented fact that up to 30% of a home’s energy loss is due to the heat that escapes through its windows. In emissions, this loss of energy from windows translates to nearly a gigatonne of CO2 released into the atmosphere each year globally – not far off the total emissions from the aviation industry.

So, without taking into consideration the industrial practices and materials that contribute to the production of your windows, an upgrade to your glazing will automatically benefit mother Earth just by being there.

Glaze Anatomy: Component Breakdown

Taken as a whole, it’s easy to see why the simple act of installing modern glazing systems can benefit you and your ecological footprint, but when we take a closer look at the individual parts that make up a window unit, the case just gets stronger. From improved industrial processes to more conscientious use of materials, every aspect is tweaked and experimented with in order to keep pace with our evolving practical needs and aesthetic tastes.

The industry is changing so quickly that it can be hard to keep up, but no fear, we’ve compiled a list of some of the more notable areas of innovation of recent years. Let’s take a look.

Glass

For a material that has been around for 4,000 years, it’s quite incredible that we keep finding ways to improve glass, but improve it we do. Anyone who has lived in a property with vintage, single-paned windows will know just how far the technology in glass production has come – and from the look of it, this progression of perfection isn’t complete yet, either.

In contemporary architecture, one of the most widely used energy-efficient glass types is Low-Emissivity glass, more commonly referred to as Low-E. A special coating is applied to Low-E panes; this coating helps to reduce heat transfer through the glass, thereby stabilising indoor temperatures, which in turn will lessen the load of your energy bills.

Smart glass technology has been around for a while now but recent years have seen a huge increase in demand for it. Its potential to lessen energy consumption and waste is widely reported – and the more we focus on sustainability as a guiding philosophy, the justification for this technology will only increase. It can even be retrofitted to existing windows, making it a lot less daunting than some of the other improvements you could make.

Frames

Window frames vary so much with regards to their ecological credentials primarily because there is so much choice available. They come in different thicknesses, styles and sizes and are made from all sorts of different materials, all of which will affect the unit’s performance.

Advancements in technology have bridged some of the gaps, though. Steel was once seen as an inferior material for window frames due to its low thermal retention, but thanks to the use of thermal breaks, this drop-off isn’t as clear-cut as it once was. On the other hand, aluminium was considered to be the lesser metal because of its strength compared to steel, but again, thanks to modern alloys, aluminium can more than hold its own in the conversation.

Seals

You can have the most expensive, high-tech windows and frames in the world, but if the seal around the unit is leaking air then you won’t be able to properly insulate your home and all that money may not pay off as you’d expected. Draught-free window units are essential for your glazing to work to its optimum level, so be sure to check that all windows are sufficiently sealed.

The Green, Green Glass of Home…

Like any improvement, making our building industry eco-friendly is a process. In the short time that sustainability has been a top priority, it’s amazing to see how much the glazing industry has evolved to meet these needs – and with another quarter of a century to come before we reach our 2050 Net Zero target, there’s plenty of time yet for improvements.

Watch this space.

If you’ve noticed a fuzzy or splotchy substance growing on your window frames, you’re dealing with a common household issue: mould. Mould on window frames is not only unsightly, but it can also cause structural damage and pose health risks. Understanding the causes and knowing how to prevent and control its growth is crucial.

The Root of the Problem: Understanding the Causes

The primary culprit behind mould growth is moisture, and your windows, especially on the inside, provide an ideal environment for mould spores to thrive. Here are the main causes:

Condensation: Condensation occurs when warm, moist air comes into contact with a cold surface, like your window glass. This causes water droplets to form and often settle on your window frames, providing a damp environment perfect for mould growth.

Leaking Windows: If your windows are not sealed properly or the sealant around your window frame is broken, water can seep into your interiors. This dampness encourages the growth of mould around your window frames.

Poor Ventilation: A room with poor ventilation traps moist air, leading to a humid environment. Bathrooms, kitchens, and laundry rooms are particularly susceptible due to the excess moisture from cooking, washing, and bathing.

Which types of windows are more susceptible to mould build-up?

Mould can potentially develop on any type of window if the conditions are right. However, certain factors can make some windows more susceptible than others:

Single-Pane Windows: Single-pane windows are more susceptible to mould growth because they lack the insulation provided by double or triple-pane windows. The exterior cold easily affects the interior pane’s temperature, leading to condensation when warm interior air contacts the cold surface of the glass. This condensation can then promote mould growth.

Wooden Frames: Wooden frames, while not particularly prone to condensation, can absorb moisture if not properly sealed or if the sealant has worn off. This makes them potentially more susceptible to mould than vinyl or fibreglass frames, which are more water-resistant and less likely to foster mould growth.

Poorly-Sealed Windows: Regardless of the type of window, if they are poorly sealed, they can allow moisture to seep in from the outside, creating a damp environment conducive to mould growth.

Windows in High-Humidity Rooms: Windows located in high-humidity rooms such as bathrooms, kitchens, or laundry rooms are more likely to develop mould. The excess moisture in these rooms from cooking, washing, showering, etc., can lead to a buildup of condensation on windows, promoting mould growth.

Old Windows: Older windows can become susceptible to mould due to wear and tear over time. The seals may deteriorate, allowing moisture to seep in. Older wooden windows may have absorbed moisture over the years, and the paint or finish may have worn off, leaving the wood exposed to potential mould growth.

Tackling the Mould Menace: Prevention and Control

The key to mould prevention and control lies in addressing the moisture issue. Here are practical steps you can take:

Promote Ventilation: Proper ventilation is vital in reducing indoor humidity. Install exhaust fans in high-humidity areas like bathrooms and kitchens. Regularly open windows in other rooms to allow fresh air in and stale, moist air out.

Use a Dehumidifier: A dehumidifier can help in high humidity conditions by reducing the moisture level in the air, making your home less mould-friendly. This is especially useful in basements and other areas prone to dampness.

Regular Cleaning: Regularly clean your windows with a mould-killing solution. This removes mould spores before they have a chance to grow.

Insulate Your Windows: Proper insulation of your windows can help reduce condensation. The goal is to keep the window surface temperature from getting significantly cooler than the room air temperature. This can be achieved through thermal or double-glazed windows, which have insulating properties.

Fix Leaks: Regularly check your windows for leaks. If your window frames are wooden, look for signs of water damage or rot. If you find any, fix them promptly to avoid creating a hospitable environment for mould.

The Mould Removal Process

If mould has already made its way onto your window frames, don’t despair. You can remove it using a simple process:

Don protective gear: Wear gloves, a mask, and eye protection to avoid exposure to mould spores.

Make a cleaning solution: Mix one part bleach with three parts warm water.

Scrub the mould: Using a stiff-bristled brush, scrub the mouldy area with the cleaning solution until the mould is gone.

Dry the area: Once you’ve cleaned away the mould, use a dry cloth to wipe the area clean. Leave the windows open to dry completely.

Remember, if mould has penetrated deeper into the window frame material or the infestation is too large, you may need to replace the window frame or seek help from professionals.

Bringing it all together

Mould on window frames is a problem that, while common, shouldn’t be ignored due to its potential health risks and potential to cause structural damage. Regular inspections and cleanliness, along with controlling indoor moisture, can prevent the growth of mould. Take steps today to protect your windows and ensure a healthier, more comfortable living space.

Aluminium vs uPVC

Those with even the most casual interest in glazing will be aware of the aluminium vs. uPVC debate. It has been going on for some time now and shows no signs of abating. Despite what people might have you believe, it isn’t easy to answer conclusively. Each material has its strengths and weaknesses. Taken as a whole, with each of these pros and cons considered, the line between them is incredibly thin. For example: the cost difference might seem to make one the obvious choice, but when other factors like maintenance and durability are taken into account, price becomes about more than just the initial outlay. Here at Mercury Glazing, we know a thing or two about windows. Here’s a breakdown of what we think the debate boils down to…

The Advantages – at a Glance

There is no doubt that aluminium and uPVC are both great materials to use in window construction. Taking a quick look at the benefits of each will give a good idea of the difficulty of the choice.

Aluminium Windows

Energy efficient
Environmentally friendly and sustainable and non-toxic
Strong and durable
Low maintenance
Extremely secure
Aesthetically pleasing
Good acoustic insulation
Can be manufactured in extra large sizes

uPVC Windows

Energy efficient
Can be environmentally friendly
Durable
Low maintenance
Affordable
Extremely secure
Aesthetically pleasing and flexible
Good acoustic insulation
Weather and moisture resistant

The Features: A Closer Look

As you can see, the positives stack up in very similar ways; the extent to which each of these aspects is true will therefore likely be decisive, so let’s take a look…

Longevity

When it comes to the lifespan of these materials in windows, aluminium has the clear advantage over uPVC.

uPVC windows are extremely resistant to rot and the effects of the weather and require very little maintenance, but do have a tendency to degrade after around 30 years and will eventually need replacing. Aluminium frames aren’t prone to this degradation and – unlike other metals – aluminium doesn’t rust, meaning the windows should last you 50 years at the very least. Similar to uPVC, aluminium windows require very little maintenance.

Aesthetics

Certain types of property suit particular types of windows. Before your specific tastes come into it, some of the choice will be made up by the style of property the windows will be a part of.

Aluminium windows are known for their clean, elegant and modern style. For this reason, they are often associated with buildings that have a contemporary feel. Equally, if the property is located in a conservation area or the building itself is listed, there is a chance that aluminium won’t be accepted as a material for use, in which case uPVC may be the way to go.

Both aluminium and uPVC come in a range of styles and colours and sizes, but the options available differ in 2 main categories. uPVC can be made to emulate the finish of other materials – like aluminium, for example, or wood – whereas because of its strength, aluminium frames can be made much larger than uPVC equivalents.

Environmental Credentials

This is another area where aluminium really comes into its own. As a material, 100% of it can be recycled without loss to its structural properties or aesthetics; its production isn’t associated with toxins or particularly harmful industrial processes and due to its flexibility can be manufactured with minimal waste.

Energy Efficiency

Historically, the question of energy efficiency between these 2 materials heavily favoured uPVC, but aluminium has made up a lot of ground in this regard in recent years. While it is true that aluminium is a far more conductive material than uPVC, meaning heat passes through it far more easily, modern manufacturers use thermal breaks between the panes of glass to increase the window’s level of insulation. The same science is used in the construction of space shuttles and makes aluminium a perfectly viable competitor with regards to thermal efficiency.

To get a better idea of a particular window’s energy efficiency rating, we recommend checking its WER (Window Energy Rating) or U value before making any purchase: you might be surprised.

Cost

Initially, aluminium comes with a significantly higher price tag than uPVC. Production, manufacturing and transportation costs all contribute to this difference. However, once its durability and longevity is taken into consideration, aluminium more often than not proves to be the more cost-effective of the two materials.

Soundproofing

While both of these materials are vastly superior to wood in their ability to block out sound, uPVC is considerably more effective than aluminium in this particular function. If mitigating the noise levels inside your property is your biggest priority, it would be hard to beat uPVC windows.

Security

Surely, as important as any other aspect of a window’s performance is its safety. Sometimes, a little compromise is to be expected in building and renovation work, but this compromise should never be on its security.

In truth, both of these materials are known for producing a window that is strong and durable and the investment you make will be a secure one. Where there might be a case for aluminium’s superiority in this regard would be the impression of safety that metal gives, but this doesn’t increase its performance in any real sense.

Irrespective of the material you choose, we strongly recommend investing in units with high-quality locks installed. Modern designs have mechanisms and reinforcements that will make them that much more impenetrable.

Decision Time: No Pane; No Gain

Getting the windows of your home right will go a long way in achieving the right feel for your property. As a homeowner, these kinds of decisions will come down to your personal priorities, limitations and tastes – and whichever of these materials you end up using, you’re sure to find something that fits the frame.
