Introducing the classic range
Expertly designed with the latest technological advancements in window profiles.
Selecting the appropriate windows for your residence is a crucial decision that can significantly impact the comfort and security of your living space, as well as enhance its aesthetic appeal. Our company has meticulously developed the Classic system, drawing upon extensive expertise and innovative concepts to deliver a window solution that is both thermally efficient and secure.
The Classic system features a unique Thermlock® multi-chamber thermal break, utilizing a proprietary construction technique that ensures unparalleled levels of protection.
Our windows boast a sleek design with slim frames that allow for abundant natural light, catering to homeowners who seek uncompromising quality. In addition, our Sheerline aluminium windows are available in a diverse array of colors, enabling you to customize your home's appearance to reflect its individual character.
Thermlock ®
Cold, crisp lines on the outside hide away our innovative Thermlock® multi-chamber thermal design, helping keep you and your property well insulated against the worst of the UK weather. Their insulating chambers act as a thermal break and work in conjunction with high performance glazing to create class leading thermal performance, far superior to traditional polyamide thermal breaks.
Sheerline’s cills also feature this same technology coupled with innovative in-built weather sealing that keep draughts and rain safely outside.
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.
For additional security, consider our laminate glass upgrade for Secured by Design accreditation, endorsed by the official UK Police initiative 'designing out crime' through physical security.
A range of colour
Our classic windows are offered in a selection of eight powder-coated matte colours, along with a high-gloss white option.
Additionally, customers have the choice of selecting a different colour for the interior to suit their property's aesthetic.
For those seeking a more durable and stylish finish, three metallic effect colours are also available.
