Sheerline Classic



Our aluminium windows are one of a kind. With only 59mm frames, you’ll offer clients larger views and modern looks. The patented Sheerline construction uses threaded screws to bind corners together internally for clean mitre joints. Say goodbye to square cut beading. Instead, ask your clients if they want stepped, flush stepped, flush contemporary, or contemporary frames.

All of our window and door locks are fully enclosed, ensuring that they don’t create a weak point for the window by breaking into the beading or glazing. Contact our Nottinghamshire team to choose from our many options for your next installation.


By using frames with multiple internal chambers, we improve the insulation and the U-values for the aluminium windows. We are making thermal efficiency a priority, as it will be for customers. And, of course, we offer laminate glazing for additional security against intrusion. That way, the aluminium windows are air tight and secure.

With triple glazing, customers can enjoy an incredible 0.9W/m2K U-value. Our Nottinghamshire manufacturing team ensures builds of the highest standards. We offer such low U-values thanks to Sheerline’s patented Thermlock® technology and full depth Eurogroove.


Our weather resistance isn’t just part of our glazing but also a huge part of our smart aluminium frames. These frames can withstand incredible temperature fluctuation without warping, thanks to polyamide thermal breaks. And, as an installer, you won’t have to worry about the aluminium window frames fitting the cills, thanks to our corner design.

Especially in refurbishment, the corners of these aluminium windows can be fine tuned to prevent misalignment. Plus, the corner design seals glass away within the unit, rather than relying on internal beading for security measures.
