I have about 50 sqm (538 sq ft) of 175 mm (7 inch) thick calcium silicate block wall that separates my KfW40+ house from the cold garage.
The ceilings have been thermally separated with insulation baskets.
Now, 200 mm (8 inch) thick mineral wool with a thermal conductivity of 0.035 will be installed on the wall. What is the best way to fix everything securely?
- Attach the insulation using insulation anchors and then install a drywall (according to the U-value calculator, there should be no risk of condensation).
I’m not very familiar with drywall construction yet, as I have mainly dealt with other trades until now.
With my approach, I don’t need 200 mm (8 inch) thick U-profiles, which would unfortunately act as thermal bridges.
The wall is 3 m (10 ft) high. To prevent the boards from bending, I would simply mount a basic 90-degree angle bracket, where one side extends slightly into the insulation (placed between two insulation boards).
What do the experts say about this? This way, I gain rigidity without creating a thermal bridge.
