Buildings with Raft Foundation
Buildings on raft foundations can be provided with thermal bridge free insulation, if the insulation is incorporated under the foundation body. Therefore, this is a particularly good solution for passive houses. In these types of constructions only thermal insulation of increased compressive strength can be used under the foundation body. Thanks to their favourable properties, foam glass granules provide a cost-efficient solution for these types of applications. An adequate thermally insulating bedding may be obtained by compaction with vibratory plate or road roller.
