Problem
The frame is structural and load bearing and steel, although of relatively thick section, vulnerable to corrosion if subjected for long periods to damp conditions.
Although the steelwork is not exposed in reinforced concrete frames, structures need to be protected to ensure long life.
The structural frame is merely a skeleton and needs a facade.
Lightweight metal framing or single skin masonry can be used to provide walls, however the insulation issue needs to be addressed to comply with building regulations.
The frame structure itself could provide a cold bridge to the exterior.
Insulation must be placed at the correct position in the structure to avoid interstitial condensation, cold bridging and the conditions under which corrosion could take place.
Solution
Construct in-fill panels and insulate with EWI system
Construct in-fill panels with lightweight steel frame or single skin masonry and insulate the total structure with a weber Insulated Render System. Use the weber.therm FT components to provide extra levels of protection with a water defence cavity and robust detailing.
