The Polyframe range of aluminium windows, doors and bi-folding doors are manufactured at our Didcot production facility. We utilise the Smarts Aluminium profile to produce a high quality, modern and aesthetically pleasing end product.

Our windows and doors have been designed to reduce heat loss by the use of a thermally broken aluminium frame with a polyamide bridge. The polyamide material has a very high resistance to heat transfer from the inner face of a frame, i.e. heat loss from inside to outside is reduced.

Strength and durability are provided by the use of aluminium sections which gives structurally sound windows and doors for total peace of mind.
