No Job Too Big or Too Small 

Thermal Acoustic Spray-On Insulation

Kelowna’s Okanagan Insulation Services proudly installs ThermaCoustic TC-417. It is a fiberglass based spray-applied thermal and acoustic insulation. It is mainly used for multi-unit residential, institutional, commercial and industrial markets for installation in both new construction and retrofit applications. 

TC-417 produces a white monolithic, non-combustible insulation blanket that resists heat flow, air circulation and moisture migration to the substrate. It is equally effective in retarding heat flow into or out of the structure as required. TC-417 can be applied to most sound, grease and oil-free substrates such as concrete, steel, gypsum board, wood and rigid insulation. It also adheres to spray-applied fire resistive materials. The single-step spray-applied process allows even the most complex surface configurations to be covered easily and efficiently with no seams or voids. TC-417 can be left exposed as a heavily textured surface or it can be covered, depending on the design and type of application.
