Live In Cardiff?? Why Choose A Sapphire Composite Door?

Stunning Designs For Your Cardiff Home

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 your Cardiff home. 

Ultimate Energy Efficiency For Your Cardiff Homes

When it comes to thermally 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 panelled door (44mm). The results prove that our door is more than 19%+ more thermally efficient than both of the alternative doors.

Unparalleled Security For Your Cardiff Homes

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. These characteristics conform to PAS 24 Security Standards, a prerequisite for achieving the ‘Secured by Design’ endorsement.

As standard our doors come fitted with a 4-hook composite door bolt which is tested to PAS 24 and secured by design accredited. 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 only 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. 

Exceptional Durability For Your Cardiff Homes

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!

Low Maintenance For Your Cardiff Homes

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

Excellent Weatherproofing For Your Cardiff Homes

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

Superb Sound Insulation For Your Cardiff Homes

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