What is a composite door made of?

The external layer of a composite door is made from 2mm of fibreglass, the material is durable, weatherproof and moulds perfectly to represent wood grain for a great look. This external shell is fused to a uPVC and hardwood internal frame with the remainder of the door being injected with a warm thermal polyurethane foam core that’s 100% CFC-free (chlorofluorocarbon).

Can you paint composite doors?

Yes, you can paint composite doors with most exterior weather-proof paints, it’s advisable to use a primer first. However, there are so many colour and finish options with our composite door range, there shouldn’t be any reason to change the colour of your door!

How much are composite doors?

Due to the sheer range of colours, finishes and additions you can add to your composite doors (not to mention the range of styles and functions available), it’s best to speak to one of our team to get the best quote for your door.
