"And the downs of the project…there haven’t been any!”


"I’d also like to thank Hazlemere and all of their sub-contractors who have done a great job particularly Joe Cross, Hazlemere’s Site Manager who has taken ownership of the project and gone beyond the call of duty ensuring each area is complete on time and any remedial works are carried out swiftly and with no fuss. And the downs of the project…there haven’t been any!”

High quality UPVC systems

Founded in 1980, Synseal Group has established itself as a market leader in UPVC window and door systems with an annual turnover of £150m and seven UK manufacturing sites including four of their own glass factories. They have built a reputation on developing quality accredited systems which have been rigorously tested to meet British Standards with excellent thermal performance. With an integrated supply chain, talented commercial team and decades’ experience working on commercial and new build contracts, Synseal is set up to support UK-wide projects of all sizes.

Synseal extrudes 3 market-leading 70mm UPVC window profile systems (Legend, Shield and Synerjy) that offer multi-chambered frame, plastic thermal reinforcement and triple glazing options to deliver the highest levels of thermal efficiency.
