Sheerline Aluminium Windows

1.4 U-value W/(m²K) Double glazed, 1.0 U-value Triple glazed
Thermal transmittance, also known as a U-value, measures the rate of heat transfer. The better-insulated a window is, the lower the U-value will be. Available with up to 44mm triple glazing for the ultimate thermal performance. Triple glazing can also provide exceptional acoustic dampening to block out unwanted noise.

Inbuilt Security
Our patented corner jointing method creates robust frames, maximising the inherent strength of Sheerline's aluminium construction. A full-depth euro groove also enables you to offer the latest high-security multipoint locking, helping to keep customers and their homes safe and secure. Additional features, such as unique hinge protectors, also help create exceptional levels of security. Prestige's cleverly integrated design also ensures that both window and door lock cases are fully enclosed, meaning they don't break through into the glazing or beading areas, which could weaken the frame's integrity. For customers seeking extra peace of mind as standard, we have them covered. For added peace of mind, choose our laminate glass upgrade – for Secured by Design accreditation* – the official UK Police initiative 'designing out crime' through physical security.
We manufacture aluminium windows, including casement and tilt-and-turn windows, with a flush sash option that brings the outer frame perfectly level with the opening part of the window. Sheerline windows are the quality option for your home. Please feel free to call us to discuss your aluminium window design needs and prices at 01179 71992,2 or visit us in person.
Triple Glazing Performance
Can I triple-glaze an aluminium window? Yes, if you want the ultimate thermal performance in your windows and doors.
Our aluminium windows are designed to accommodate the weight of triple-glazed units as standard; choose this option for the ultimate thermal performance, 75% better than that of standard double-glazed windows. Opting for 44mm triple glazing rather than standard 28mm double glazing reduces the whole window's U-Value rating from 1.3 to 0.8. Triple glazing is ideal for Sheerline windows installed in exposed locations and can help reduce noise.
High Strength Construction
Need Strong Windows? High Strength Construction
From the design of the unique thermal core and the outer faces of the profile, which are high-grade aluminium positioned to add the most significant structural rigidity, to the 60-80 micron thick (exceeding marine grade) powder coat finish, Sheerline has been designed to stand the test of time.
All fixings used are chosen to resist corrosion. Multipoint locks and purpose-designed hinges have been precision-engineered to perform consistently every single time, year after year.
