Problem
Lightweight steel frame is structural and load bearing and, although galvanised, vulnerable to corrosion if subjected for long periods to wet conditions.
Steel frame has no insulation properties of its own.
Insulation must be placed at the correct position in the structure to avoid cold bridging, interstitial condensation and the conditions under which corrosion could take place.
The NHBC recommends a water defence cavity between the frame and external cladding.
Water defence detailing at openings is critical to the longevity of the structure.
Solution
Use weber.therm FT and EWI system
weber.therm FT's components have been designed to be used with the weber.therm XM external wall insulation system to satisfy all requirements for cavity and robust detailing.
The system has been accepted for guarantee purposes by the NHBC.
