Why choose CompDoor

At the heart of every Comp Door is a premium cross laminated timber core, designed to be thermally efficient and offer maximum security. The timber core is then wrapped in revolutionary, high-performance CoolSkin technology, engineered to withstand extreme temperature changes and maintain optimum impact performance, with a colour protective layer so that it won’t get worn away or chipped.

Comp Door is built to last, delivering market-leading U-values for high energy efficiency, Improved weatherproofing and reducing chance of drafts for a cosy home that is comfortable, safe and secure.

After all, why compromise on safety when your Comp Door is fitted with the renowned ABS anti-snap diamond grade cylinder, as standard, for ultimate defence. Thermal movement can be part of any composite door product. Our unique core combined with our Auto Slam Shut lock as standard, is designed to minimise this.
