One in four UK windows and doors is now manufactured in colour and demand is showing no sign of slowing, with one in three windows likely to be coloured before the end of the year.

Kolorseal, headed by Deborah Hendry, has more than 20 years’ experience in the industry.

“Our entire operation is focused on quality and service,” she said. “Experience enables us to understand that no installation can be completed unless all the components are present and correct.

“But it is attention to detail that drives Kolorseal forward. Whether it’s the detail product checklist that is issued, tracked and signed off before delivery, or the quality of our finishes, we have perfected our service to ensure we support our customers in the best possible way when it comes to colour coating their windows and doors.

“Convenience is also key. As well as strict turnaround promise of 5+1 days on basic colours, we also offer a delivery and collection service from our Dewsbury depot. This includes any window and door related product, including trims, fascia, soffits, cladding and roof vents, painted in standard RAL and BS colours or colour match to any other colour system.”

Kolorseal’s solution forms a molecular bond with the surface of the PVCU, effectively becoming part of the structure of the material as opposed to simply adhering to it. Therefore, Kolorseal can offer a ten-year guarantee that covers stability and adhesion.
