Sarnafil Flat Roof Systems
Sarnafil launched its first waterproofing membrane in Switzerland over 40 years ago and many early Sarnafil roofs installed in the 1960s are still performing superbly today.
Here in Great Britain, Sarnafil roofing has been specified for many prestigious projects such as Arsenal FC’s new Emirates Stadium; the Bluewater Retail Centre, Kent; Heathrow, Gatwick, Stansted and Bristol Airport passenger terminals; and the new St. Pancras Railway Station
