摘要

The invention relates to a method for producing an insulating composite block comprising a mineral foam, said method comprising the following steps: a. providing a block comprising at least one cell having walls which are either sufficiently humid or consist of a water-repellent material, and b. filling said cell with a mineral foam that does not substantially comprise any calcium aluminate. The invention also relates to an insulating composite block comprising a block, said block comprising at least one cell having walls optionally comprising a water-repellent material, said cell being filled with a mineral foam that does not substantially comprise any calcium aluminate.
