Guide to choosing steel frame wall insulation
Steel frame constructions offer a practical solution both for mid and high-rise buildings, and as part of modular home systems. As with all external wall constructions, the choice and position of the insulation can have a notable impact on the thickness of the construction and the finished floorspace within the building, so it is important to carefully consider the different options.
This article looks at a number of key points to consider including:
- Should steel wall insulation be fitted between or outside the studs?
- What insulation is best for steel frame wall constructions?
- What U-values should steel frame walls achieve?
Where should insulation be fitted?
We recommend warm constructions for steel frame walls. This is where the insulation is fitted externally, sheathing the studs. This sheathing insulation can either be fitted by itself or in combination with a suitable between stud or internal insulation. This warm construction helps to minimise thermal bridging via the studs and also limits condensation risk as the external face of the stud is not left exposed to the cold.
