Composite Doors Designed For Strength and Style
Our composite doors are designed to offer the best of both worlds, combining the timeless appeal of traditional timber with the practicality of modern uPVC. Crafted using advanced composite materials, each door features a robust glass-reinforced plastic outer layer and a solid foam core for superior performance.
This intelligent construction makes our doors highly resistant to draughts and external noise, creating a warmer, quieter living environment. In fact, our composite doors deliver up to six times more insulation than standard doors, helping you enjoy year-round comfort and improved energy efficiency.
Perfect Alternative To Hardwood
Our composite doors in Leatherhead combine the timeless charm of natural timber with the durability and security of modern uPVC, giving you the perfect balance of style and performance.
Low Maintenance Composite Doors
It’s not often you find a product which requires very little maintenance. Our composite doors only need occasional cleaning to retain their stunning looks, their beauty will never fade. A tough exterior skin makes them less prone to scratching or denting, especially when compared to steel-faced doors.
They will never require re-painting or varnishing either and are fully weatherproof thanks to a triple weather seal. This seal includes on external gasket as well as two wool pile barriers which successfully keep the outside elements at bay.
Energy Efficient Composite Doors
Our composite doors in Leatherhead are expertly designed to deliver outstanding energy efficiency, achieving a B energy rating as standard. This impressive performance comes from their innovative construction, which combines a rigid foam insulation core with a tough GRP outer layer. The result is a door that helps retain up to six times more heat than a traditional timber door, keeping your home warm and comfortable throughout the year.
To further boost performance, each frame is fitted with thermal inserts made from 100% recycled uPVC, improving sustainability while enhancing insulation. For homeowners looking for the very best efficiency, we also offer A-rated composite door options, giving you the ultimate upgrade in energy savings and eco-friendly design.
