K-13 is a spray-applied insulation tailored to your specific project requirements for insulation (R-value), noise reduction (NRC), colour, durability, condensation control, texture, and aesthetics. In addition, it usually provides these features at lower installed prices than many common systems such as rigid board and batt insulation, sprayed plasters, and acoustical ceilings. It is applied to wood, steel, concrete, glass and other common construction surfaces. K-13 can be sprayed up to four inches thick overhead in one application without mechanical support. Additionally, K-13 serves as the exposed finish, requiring no additional materials.
