Create your dream door today with our Door Designer. We offer strong and durable composite doors

The Right Materials, the Right Style

Not all composite doors are made the same. We appreciate that every Sheffield home has its own quirks and personality which is why our doors have bespoke options to  tailor your specifications and requirements specifically to your new composite doors. Solidor have enabled us to provide all our valued customers with a home improvement solution that benefits them – you can really make the most of our composite doors and below are just some of the benefits that our doors provide:

Best Locks

Whatever style of composite door you choose, you can get an incredible locking system. Solidor’s composite doors use the Avantis lock. This is the first lock that has a 25mm triangulated deadbolt. The Avantis lock also creates greater compression when closing and the deadbolt is active by lifting the handle.

Ultion locks are a standard feature in our Solidor composite doors. Ultion is considered as a state of the art piece of technology with a £2000 guarantee that their locks will not snap – you can trust that your Sheffield home will be safe with our Solidor composite doors.

Dual Colour Options

When you choose a Solidor composite door, you have 23 beautiful colours to choose from. But even more impressive is that you can choose dual colours: one for the interior and one for the exterior of your home. If you have difficulty choosing just one colour, why not choose both?

Try our chamfered or sculptured frames for colour accents. We offer everything from Tangerine to Midnight Grey and woodgrain finishes like Walnut or Rosewood, so you’ll never have to worry about painting your door.

Solid Timber Core

One of the main benefits of Solidor’s timber core is the fact that it isn’t just a wooden material. It’s extremely sustainable and environmentally friends; most standard suppliers’ doors include products that use a foam core – meaning that the door is lighter, less weatherproof and secure.

Instead of this standardised material, our timber doors are draught resistance and can be recycled later rather than going straight into a landfill. We believe in environmental standards and our doors are the most ethical on the market at the moment!

Door Designs

Solidor composite doors do not just come in a traditional or cottage door designs. They also offer French doors, stable doors and their Italia collection. The Italia collection includes modern designs and geometric shapes; choose a contrasting colour door frame for maximum impact.

Although, if you are interested in a bolder statement, D&I can install your Solidor composite door with matching side panels. Your panels can be to the left or right of your door – or even surrounding them completely with 3-5 panels too, the choice is yours!
