Our Distinction GRP (Glass-Reinforced Plastic) composite doors for trade 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.

When it comes to thermally efficiency, a Sapphire Windows composite door for trade is the best choice you can make. 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 17%+ more thermally efficient than both of the alternative doors.

uPVC Windows & Doors

We are an accredited Deceuninck fabricator. For trade we currently fabricate the Traditional 2500 windows & doors, the heritage flush sash windows & the Slider 24+ patio door. 

Traditional 2500 

Our Traditional 2500 are the perfect trade windows. Our double glazed windows achieve an A* 10 energy rating, providing superb thermal insulation. Our best triple glazed windows achieve A*25 energy rating for the best in energy efficiency and comfort in the home. 

The system’s eye catching clean sharp lines and smooth chamfers are the perfect solution for every house style, improving any house’ appearance whilst also offering low maintenance and durable windows. 

Heritage Flush Sash

The Heritage Windows and Door Collection combines the elegance and styling of traditional timber windows with all the added benefits of PVC. They are virtually maintenance free, have excellent energy efficiency and high security. 

Designed to replicate the appearance of timber, flush sash windows are distinguished by sashes that close into the frame and finish flush with the face of the window. When open the flush sash opens outwards. Flush Sash windows have the added benefit of allowing all the window frames to be the same size (equal sight lines). 

The hertigae flush sash allows our trade customers to offer a product that’s different to the rest, offering you that competitive advantage. 

Slider 24 + Patio Door 

Our uPVC sliding patio doors for trade are designed to complement our entire range of uPVC windows so you can get the perfect colour match. 

Designed for a secure and effortless operation, our trade uPVC patio doors feature adjustable tandem rollers and anti-lifting blocks. Tandem rollers enable a smooth slide action whereas the anti-lifting blocks prevent the leaves from being taken off the tracks.


Aluminium products have become increasingly popular for domestic use as well as commercial in recent years. Aluminium offers many benefits such as strength, durability and high thermal efficiency. Given Aluminium’s inherent strength, this allows the use of narrower profiles with slim sightlines which can create large expanses of glass, allowing more of the outside in.

We are able to offer Windows, Entrance Doors, Patio Doors, Sliding Doors, Bi-folding Doors, Slide & Swing, Curtain Walling, Flat & Walk on Rooflights, Roof Lanterns and more in Aluminium.

All our aluminium products are available in an extensive range of colours and design.
