Door Features

These aren't your average high-street-quality composite doors. Our doors have a range of features for added safety, quality and longevity.

Premium Frame Profile

The frame of your door has a lot of heavy lifting to do, which is why the quality of the profile used in the frame is so important. Our doors use a high quality profile system designed to last longer and keep your door in good shape.

Aluminium Edge Banding

While most composite doors use a plastic edge banding around the door panel, ours use a sturdy aluminium edge banding. This gives our doors extra reinforcement and reduces the risk of warping, something that older composite doors struggled with.

GRP Insulated Door Panel

All of our composites (unless otherwise stated) are Insulated and thermally efficient, providing protection against drafts. Insulated cores provide more thermal protection while being lighter and just as secure as solid timber cores, due to the quality of the layers used in the manufacturing process.

All of our doors are brand new unless otherwise stated (we get the occasional door that has previously been fitted but we will make this very clear).

We are a trade manufacturer of composite and UPVC doors (and windows) and occasionally we get mismeasures. These can come as a result of mismeasurement of the door opening, incorrect measurements during manufacturing, incorrect panel size being ordered, wrong colour being ordered etc.

Due to this we get brand new doors that no longer have a buyer, leaving us with this mismeasured stock!
