Thermal Insulation

Kingston residents will be able to keep warmth in their homes year-round with our insulated composite doors. We use the market-leading Eurocell profile, with the doors manufactured with a base of layered timber, providing excellent levels of thermal retention.

Our pioneering materials combine durable glass-reinforced plastic with a sturdy foam core. This provides the Kingston homeowner with up to six times more insulation than a regular wooden door.

We all want to save on our energy bills, especially with energy costs rising. Composite doors allow for heating efficiency by maintaining the cosy environment and keeping the cold out. It is becoming fundamental to be more eco-conscious in our daily routines. Our doors will help reduce the negative impact of both electricity and heating on the planet. It’s a win-win!


With our busy lives, we often look for products for our homes that require little care. Composite doors are ideal in their durability, keeping their vibrant colour looking fresh. To clean, simply taking a damp cloth and wiping down the frame and glass every so often will help to keep your stylish entrance looking just like new.

While steel-faced doors are much more prone to scratches, composite doors manufactured with durable materials make both scratching and dents issues of the past.
