Techniques have not changed much from this vintage video, even the basic roof repair and maintenace is followed before spraying. The bonding materials have improved and thickness of spray foam has increased too from experience. The 25 year guarantee still stands and technicians are better trained than the 1970’s. We only employ master sprayers. The free survey is available with the added bonus of a thermal survey included in the visit.
The system is an ideal means of insulating your home, even for homes built before 1940’s. call 0845 474 6641 for further information.
