uPVC Sash Windows
Our uPVC sash windows are designed to be the perfect timber replica. Their composition makes them a perfect solution for conservation areas and other heritage buildings. They slide vertically and can also tilt within the frame, providing an easy maintenance solution for homeowners in your coverage area.
Additional design features, such as run-through sash horns and a deep bottom rail, are available to add an authentic touch of class to the uPVC sash windows. Plus, we are pleased to offer 90-degree mechanical joints for a sash window replacement that doesn’t compromise on the original aesthetic. The 90-degree mechanical joints and seamless welds are available for woodgrain foil only. There are also seamless welds available for woodgrain only that disguise the 45-degree weld completely for those looking for a completely uninterrupted finish.
With our optional authenticity features, these windows can look as close to timber as possible while granting much higher energy efficiency, security, and lower maintenance requirements. As a brand-new feature, we’ll also soon offer a slim mid-rail as an option for our uPVC sash windows.

Weatherproofing
Our Legacy uPVC sash windows are built to last and to resist the ever changing conditions the British weather throws at them, all without losing their immaculate appearance. An aesthetically pleasing weather bar and high-quality integral window cills add additional and unique levels of defence against rainwater. Our colour-matched wool piles also add robust seals against wind and rain while maintaining a seamless aesthetic.
Thermal Efficiency
The frames and sashes are multi-chambered and use the power of specialised argon gas to help trap heat between the panes. Our modernised double-glazed sash windows can make an excellent timber replacement as they can achieve an energy rating of ‘A’. Additionally, they can reach a U-value as low as 1.4 W/m2K. Homeowners can stay warm year-round when you choose Super Shield UK.
Security
Our double-glazed sash windows deliver the most advanced levels of security without adding complex operations. They are practical and come with all the safety features a homeowner would need. They have the option to take advantage of a comprehensive high security PAS 24 package, which meets the latest requirements for new builds. Avia smart hardware is also available and can be retrofitted for those looking for a contemporary security solution.

Amazing from start to finish
Found Arctic through google and what a find. From the moment we met Bill they had our trust. We were constantly kept up to date and two further measurements taken before installation date was confirmed 3 weeks later. The team completed the installation in one full day to a very high standard. Highly recommended.

Excellent service
Just had windows and door from arctic great service from start to finish very pleased with the finish and look Calvin very easy and friendly to deal with no hard selling everything went smoothly and on time and Dave and Yvonne worked on late to finish rather than leaving to next day would definitely recommend

A speedy process from start to finish
A speedy process from start to finish. Excellent work by the fitters who worked hard and cleaned up thoroughly, inside and out. I’m very satisfied with the result.

Highly recommend
From Darren’s initial visit to Jamie and Calvin fitting the windows everything was excellent, very friendly and professional. Would definitely use them again when replacing the doors.
