Window frame colours and finishes

Most Sheerframe window, door and curtain walling systems are available in white or woodgrain finishes.

Three different approaches are used to achieve these:

Through-Frame Pigments

Both wood effect and white finishes are achieved by adding stable pigments to the polymer, resulting in an even distribution of colour and a smooth surface appearance. Sheerblend materials are colour stable and are compounded by Sheerframe. They comply with BS7413 for all aspects of long term performance. The pigment systems used have been developed following extensive natural weathering trials and artificial ageing studies over a 30-year period.

Woodgrain Foil Finishes

Several different timber effect finishes including light oak and mahogany are fused to the surface of the profile by means of a heated silicone wheel. The woodgrain foil is fused to the PVC in the absence of any substrate using heat and pressure.

These foil finishes meet all the requirements of the British Standard for surface coated PVC profiles BS7722. Independent weathering tests carried out by the BRE to the method of tests in BS7413 for white profiles show excellent adhesion, gloss and colour retention.

Specialist Paint Finishes

In recent times, specialist paint formulations have been introduced, which are designed to etch into the surface of the PVC, giving good long-term bonding and adhesion. The advantage of these finishes is the extended colour range possible.
