PVC Windows, Doors & Sliding Systems
Engineered by REHAU, one of the world's leading polymer specialists. The SYNEGO platform combines exceptional thermal performance with a clean, modern finish across windows, lift-and-slide patio doors and everyday sliding systems.
SYNEGO
An 80 mm, seven-chamber profile delivering near-passive-house levels of insulation. The High Definition Finishing (HDF) surface stays smoother and cleaner for longer, and the system carries high security and acoustic ratings — a superb all-round choice for UK homes. Matching SYNEGO front doors are also available on the same 80 mm platform.
