Why use Winsulite™ uPVC?

‘Unplasticised Polyvinylchloride’ (uPVC) is used extensively throughout the world in the building industry.

It is a highly resilient material that is energy efficient, non-corrosive, durable, weatherproof, and inured against UV radiation. Meaning the windows and doors will likely outlast the house they’re installed into.

uPVC requires little  maintenance and no painting or treatment. These qualities make uPVC an ideal material for windows and doors.

Weather Proof

Our windows and doors have 2 or 3 weather seals and, depending on design, these seals protect each opening, allowing the windows and doors to remain completely draught and waterproof, even under the most severe weather conditions.


Up to 10 different locking points can be added to our windows and doors, and when used in conjunction with toughened safety/laminated glass, this would make it virtually impossible for intruders to gain entry.
