Core insulation
In core insulation, the thermal insulation material (glass wool, rock wool, EPS granules, or mineral granules) is introduced into a double-walled masonry through a narrow blowing opening. The cavity generally fills from the bottom up with the insulation material. This behavior depends on the respective insulation material, and the material must be introduced according to manufacturer specifications.
In the best case, the insulation material is now space-filling, free of voids, and filled with as uniform a density as possible, thus providing thermal insulation. The uniform distribution and installation density are crucial for the thermal insulation properties and settlement safety.
Typically, blowing tools use blowing nozzles with pipe diameters ranging from 18mm to 29mm. They can be equipped with rotating nozzle heads and specially shaped outlets.
