Ultra slim 59mm sightlines of the innovative Classic window system maximises the light flooding into your developments.
Sheerlines Classic double glazed windows, with standard high performance glazing have a U-value as low as 1.4 W/(m2K). While our Prestige windows are as low as 0.9W/(m2K) when specified with triple glazing.
With an integrated system design and our own UK based manufacturing, Sheerline products are available on shorter leadtimes - helping you meet project deadlines - even on dual colour specifications.
All our windows and doors are stocked in eight powder coated matt colours, as well as a high gloss white, with the option of choosing a different colour for the interior on standard leadtimes. A further three anodised finishes are available for the ultimate durable and stylish finish.
A host of features including our patented corner technology and beadless Classic system drastically cut down on remedial site issues.
Our ultra slim Classic system features beadless glazing, saving installation teams time on site - helping you get water-tight builds quicker.
Our patented corner jointing method does away with the need for crimping and specialised machinery, drastically reducing waste and improving quality. Allowing for easy replacement of sealed units on site if required. Larger frames can also be assembled in situ if required.
Our unique Thermlock® closed-cell, insulating chamber, hidden away inside every Sheerline window and door act as a
thermal break, creating products with class leading thermal performance.
Sheerline’s cills, ancillaries and corner posts, also feature this same technology coupled with innovative in-built weather sealing that keep draughts and rain safely outside.
No element of the Sheerline system has been overlooked, which helps eliminate any condensation issues caused by cold bridging.
Our patented construction method – using threaded screws to bind corners tightly together in perfect unison – allows
the Classic system to be beadless, creating perfect run through mitres on internal joints, doing away with the unsightly junctions of square cut beads seen on most aluminium windows.
We’ve also designed out the stepping of misaligned corners, allowing each Sheerline window to be individually hand tuned to improve quality.
