Thermal insulation is installed in building envelopes to control the flow of heat in and out of a building. SWSC can install a variety of materials to meet different types of construction. These include fiberglass or mineral wool batts within stud cavities and rigid board at CMU walls.


Acoustical Insulation refers to products that control noise transmission through walls, floors and ceilings. Products commonly used for sound transmission include fiberglass or mineral wool batts installed within stud and joist cavities. Other methods include semi-rigid boards or spray applied cellulose applied directly to substrate to absorb sound waves. This method is commonly used in arenas, sound studios and theaters. SWSC is a certified installer of K-13 spray-applied cellulose.
