For any areas of flat roof we use a Sarnafil singly ply membrane which is BBA certified to have a life expectancy of over 40 years.
A lead effect colour is normally used, and Sarnafil is generally accepted to be neater and more durable than lead itself, but at a fraction of the cost. Sarnafil is undoubtedly technically and aesthetically superior to any alternative synthetic solutions such as glass fibre or rubberised membrane,
It has been used on widely in the commercial sector for many years, on many prestige projects such as the Emirates Stadium, Bluewater Shopping Centre and Stanstead Airport. Click here to visit their web site for further information and reference projects.
