High performance composite doors in North London & Essex

Composite doors are some of the most secure, thermally retentive and energy efficient doors available. 10% thicker than other composite doors on the market, and combining the easy maintenance of uPVC, and the aesthetics and strength of timber, our Solidor composite door installations can truly enhance the look, and security, of a home.

Best qualities of uPVC & timber combined

Thanks to their hybrid design, Solidor composite doors combine the best properties of uPVC and timber to create one of the highest performing doors currently available on the market. Joining the easy maintenance and thermal retention of uPVC with the durability and strength of timber, composite doors fuse the best of both materials, forming a door at the height of technology.

Enhanced security and weatherproof protection

Our composite doors can also incorporate what’s known as a dual rebate for even more security enhancement. Put simply, a rebate is a deep groove cut into the edge of the door frame, allowing for a much tighter fit. The natural thickness of a composite door means they are highly suited to incorporate this.

Dual rebate frames are easy to fit and install thanks to their sleek design, they are robust and offer less room for error when compared to traditional single rebates. Fully sealed and offering brilliant protection against water penetration, a dual composite door from dolphin has excellent thermal and acoustic insulation.

Wide range of Solidor styles to choose from

We have more than 60 Solidor door styles to choose from, available in 18 colours. This makes it easy to choose a composite door that reflects your personality – opt for more traditional woodgrains, contemporary greys and blacks, or something in between.
