Why Choose A Sapphire Windows Composite Door?
Stunning Designs

Sapphire Windows GRP Composite Doors are aesthetically pleasing and are available in a huge range of colours and a variety of hardware and glazing options. 

The woodgrain finish on our GRP composite door is developed from oak tree wood grain, creating a beautifully authentic appearance and superior performance that is only available on our Distinction doors. 

Our stunning door designs would make a welcome addition to any home. 

Ultimate Energy Efficiency

When it comes to thermal efficiency, a Sapphire Windows composite door is the best choice you can make. It’s the most energy-efficient door on the market. 

Our composite doors exceed Approved Document L of building regulations, helping to keep your home insulated and your bills down. 

Our Distinction signature composite door (44.5mm) has been independently tested against a solid timber core composite door (48mm) and a timber paneled door (44mm). The results prove that our door is more than 19%+ more thermally efficient than both of the alternative doors.

Low Maintenance

Everything about our GRP composite door is designed to be easy to maintain – simply wipe clean with warm soapy water. 

Exceptional Durability

Sapphire Windows provide GRP Composite Doors with pedigree, offering strength, high impact resistance, and stability. Each door is backed with a 10-year guarantee and a FENSA Certificate!

Unparalleled Security

Our Distinction GRP (Glass-Reinforced Plastic) composite doors offer enhanced security thanks to their rigid polymer sub-frame, high density insulated core, and high impact resistant GRP skin.

As standard, our doors come fitted with a 4-hook composite door bolt which is tested to high security standards. These locks have four opposing hooks and a deadbolt throw for maximum security. Although highly secure, our locks ensure a smooth and robust operation of the doors.  

At Sapphire Windows, we do not compromise on our composite door’s security. By using the ULTION 3-star security rating & Sold Secure Diamond accredited cylinder, we have ultimate confidence in the security of our doors. Our ULTION cylinders come with a £1,000 burglary guarantee. 

Excellent Weatherproofing

With water-resistant polymer composite rails, our doors will keep the weather at bay and will stay looking greater for longer. 

Superb Sound Insulation

With a weighted noise reduction of 31 decibels, it means you can be sure your new door will keep outside noise to a minimum.
