What are Alitherm aluminium windows?

Alitherm aluminium windows are premium thermally-efficient windows, that offers great thermal performance for economical heating. 

Why choose Alitherm windows ?

Alitherm windows are designed to be an energy-efficient and versatile solution for residential and light commercial installations. Its contemporary window design takes influence from traditional timber frames, making it unobtrusive and a sleek, elegant option for modern spaces.

Alitherm 800 windows rely on polyamide thermal break technology to provide a conduction barrier between internal warm air and external cold air, which significantly reduces heat loss. They’re available in side and top-opening styles, as well as open-out, parallel and reversible top-swing. This makes them perfect for both residential and light commercial installations.

Choosing between Alitherm 800 and Alitherm 300 windows

Both the Alitherm 300 and Alitherm 800 windows rely on the same manufacturing technology to offer efficient residential and commercial windows. However, the 800 series offers the highest thermal performance of the Alitherm range. 

The 300 is available in glazing sizes between 24mm and 36mm with a frame depth of 53mm or 70mm, whereas the 800 accommodates 24mm or 28mm glazing with a frame depth of 70mm.

Choosing your Alitherm 800 windows

Materials

Alitherm windows are manufactured by Mercury in our dedicated state-of-the-art manufacturing centre in Gloucestershire, using cutting-edge fabrication processes to deliver exceptional quality on every product. Each frame receives a marine-quality polyester coat to ensure durability against the weather, involving three chromate-free polyester powder coats.

The aluminium windows feature a polyamide thermal break, which is a material manufactured between two pieces of the aluminium frame, made of enduring polyamide. This means your aluminium windows are thermally efficient and will help to retain your building’s internal heat and boost energy efficiency.

You might also like to know that aluminium is 100% recyclable, so when your windows reach the end of their life, the material can be repurposed. In fact, nearly 75% of aluminium ever produced is still in use today

All our Alitherm windows are manufactured using sustainable methods and materials, with the aim of carbon-neutral production in the future.

As previously mentioned, Alitherm 800 is available in different window-opening orientations with different dimension limits.

For side-hung opening orientations:

Max width: 700mm

Max height: 1400mm

Frame depth: 70mm

 

For top-hung opening orientations:

Max width: 1400mm

Max height: 1300mm

Frame depth: 70mm

 

Both styles can take double or triple glazing units with a 24mm or 28mm depth.

If you’d like sizes outside of those mentioned, contact Mercury Glazing today to discuss your bespoke needs.

 

Weatherproofing and thermal properties

Alitherm’s aluminium windows’ extended polyamide thermal break offers an ‘A’ rating under the Window Energy Rating system. Alitherm aluminium windows offer between 1.5W/m2K and 1.2W/m2K thermal transmittance, also known as a U-value, making them energy-efficient by design.

Mercury Glazing manufacture Alitherm windows within the UK, so naturally they’re ready to take on the Great British weather. As well as the marine-grade polyester coating to prevent corrosion, they also feature high-quality rubber gaskets and weather brushes to prevent water ingress to the frame or window.

Colours available

These aluminium thermal windows feature frames that come in both traditional and more contemporary finishes. Varieties include metallic, textured, dual-colour and anodised effect finishes. Paint finishes are machine-sprayed to guarantee consistent and precise colour matches on every frame.

Any RAL colour is available for window frames. RAL is a European colour matching system containing a wide range of hues and tones that would suit most colour schemes.

If you have a specific colour in mind but you’re not sure whether it’s available, get in touch with us and we can check on your behalf.

EPC Rating

Energy Rating

To help consumers understand which windows are economical, the fenestration industry has  established window energy rating guides or WER’s from the British Standards Institute. 

The WER is a useful guideline for anyone looking to reduce fuel bills or their carbon footprint, and you’ll likely find them similar to the colourful labels that can be found on any new household appliance. WER labels describe the energy efficiency of a window and its frame and give information about thermal transmittance, solar protection, air leakage and an ‘energy index’ which represents the solar heat gains minus the thermal losses.

Thermal transmittance is described as a U-value and represents how easily heat can transfer between sides of the material. A lower number means that a window is more energy efficient, and building standards say that a window should be rated at or lower than 1.6W/m2K. Alitherm windows are rated between 1.5W/m2K and 1.2W/m2K, showing that they exceed minimum efficiency by design.

This high thermal efficiency, combined with durable manufacture and a tough polyester coating means that aluminium thermal windows could potentially help you save money over the lifetime of the window.
