PVC-U Fully Welded Vertical Sliders

If you are looking for a solution that combines modern technology with the classic aesthetics of traditional British architecture, then our PVC-U Fully Welded Vertical Sliders may be the answer.

Commonly used in historical refurbishment projects and conservation areas, Mercury Glazing’s range of sliding sash windows are the perfect solution when preserving the architectural character and charm of your property. PVC-U is also a suitable material for use in contemporary projects and can add an elegant and understated finish.

What are PVC-U Fully Welded Vertical Sliders?

Representing decades of technological innovations in the window industry, our seamless and elegant Spectus vertical sliders have become increasingly common in recent years due to a need in the market for contemporary solutions to worn out timber windows in older properties. While Britain’s properties are an iconic part of our long history and add a charming element to the architecture of our towns and cities, many properties are in desperate need of added insulation and security.

PVC-U Fully Welded Vertical Sliders look like traditional sash windows, elevating your property with added thermal insulation and modern locking mechanisms. Suited for a variety of different properties, including contemporary builds, the traditional aesthetics combined with modern technology makes PVC-U the ideal solution when updating heritage buildings.

Put simply, you will not have to compromise on the benefits of modern technology when preserving the charm and character of your property.

Available with the Ultra Slim Vertical Sliding Sash Meeting Rail for No-Compromise Heritage Projects

At just 37mm deep, our Ultra Slim Vertical Sliding Sash Meeting Rail brings together the classic elegance of traditional proportions, further adding to the appeal of our popular range of PVC-U products.

The system offers a functional choice for installers, with a 128mm outer frame that aligns with box sash measurements and the availability of either a 150mm or 210mm sill. It holds a Kitemark according to BS EN 12608, is PAS 24 certified, and is engineered to meet Secured by Design standards, making it compliant with Document Q.

The introduction of the ultra-slim meeting rail brings a new level of authenticity to PVC-U sash windows, and with our range of colour options combined with outstanding thermal performance Mercury has cemented itself as the go-to supplier for modern heritage windows.

What Properties are Vertical Sliding Sash Windows Suitable for?

Spectus vertical sliders are the perfect choice for those looking to add a vintage aesthetic to their property as they are designed to replicate the classic style of a traditional timber sash window. They are a great choice for listed buildings or for those who are seeking to incorporate character into their home. Not only are they aesthetically pleasing, vertical sliding sash windows are also highly functional thanks to the high degree of insulation they offer. As an added benefit, they are made from strong and quality PVC-U which is low maintenance and provides a high degree of durability whilst visually compatible with an older building.

How Easy are Sash Windows to Install?

Installing sash windows is usually a straightforward process, though with certain types of sliding sash windows it can require professional attention. PVC-U Fully Welded Vertical Sliders make the installation process easier as they come fully assembled and ready to fit straight into a window aperture. As they don’t require any painting or further work to make them fit the new opening, they can save on installation time and costs. It is also possible to retrofit these sliding sash windows into existing frame openings, meaning they are an ideal choice for those looking to replace old, drafty windows with a more modern design solution.

How Long do Sash Windows Last?

When considering the potential performance of sash windows, one of the most important considerations is how long they will last. PVC-U Fully Welded Vertical Sliders are one of the most popular choices for sliding sash windows, and with regular maintenance and upkeep, even these Windows can last up to 20 years or more. It is important to remember however that even the best quality types of sash windows require regular maintenance and, over time, may need to be replaced or repaired in order to retain their best performance.
