Thermlock ®
Prestige offers a sophisticated blend of aluminium aesthetics and outstanding thermal efficiency, achieving an impressive A+ Window Energy Rating.*
Our cutting-edge Thermlock® multi-chamber thermal system, discreetly integrated within each window and door, ensures superior insulation against harsh UK weather conditions.
This closed-cell insulating chamber serves as a thermal barrier, working in tandem with high-performance glazing to deliver top-tier thermal efficiency, surpassing conventional polyamide thermal barriers.
Additionally, Sheerline's cills incorporate this advanced technology along with built-in weather sealing, effectively keeping drafts and rain at bay.
Patented Design & Construction
The Classic window system features ultra slim 59mm sightlines that enhance the amount of natural light entering your home, resulting in a sophisticated architectural appearance. Our patented construction technique utilizes threaded screws to securely join corners in precise alignment.
This eliminates any corner stepping issues, enabling each Sheerline window to be meticulously hand-tuned for optimal performance. The end result is a harmonious blend of subtle elegance and exceptional quality standards.
Exceptional Security
The Classic system by Sheerline utilizes an innovative construction method to create exceptionally strong frames, maximizing the inherent strength of our aluminium windows.
Paired with our high security multipoint locking system, this ensures a safe and secure environment for you and your home. Unique features such as hinge protectors further enhance the security levels. For the highest level of security, the Classic window system offers a beadless option, eliminating the need for separate glazing beads. Our patented corner jointing method securely locks the glass within a completely sealed unit.
Sheerline windows are all PAS24:2016 enhanced security accredited, providing stylish aluminium windows with added peace of mind as standard.
