EWI to Door Threshold [Version ID #155]
Detail summary
Detail for insulating below ground where an existing door, with a step, is to be retained. For use where floor void inaccessible by usual means and is not possible to lift whole floor.
Using a granular insulating infill below an existing concrete stone step increases the thermal efficiency of the building thermal envelope, and prevents cold bridging through the existing door threshold.
