Composite Doors

Composite doors are an increasingly popular edition to any home. They replicate the traditional look of wooden doors but offer the high performance and style required of a modern door.

Not only are they low maintenance, robust and weather resistant, they also boast a longer life span than both wooden and uPVC doors and their rigidity helps to protect against intrusion.

Please contact Windowmate for more information. 

Composite doors win on performance, security and style.

Achieve the sought after appearance of solid timber without the worry of rotting, warping or twisting over time and the maintenance to ensure upkeep.

The GRP (Glass Reinforced Plastic) skins are depression moulded, featuring a timber grain effect and high definition panels to provide an authentic timber-like door but with minimal maintenance.

A huge range of style and colour options are available to suit any home.

*Please note that Composite Door brands may vary between each of our branches.
