PENOSIL Easy Spray Foam Insulation. DIY Sprayable Foam Sealant with unique spray applicator for the best insulation experience. The combination of EasySprays special formula and spray applicator creates a unique foam structure with highly efficient acoustic and thermal insulation and great airtightness properties. The thickness of insulation layer is freely selectable, and the number of layers is not limited. Using accompanying spray nozzle allows to insulate uneven or hard to reach surfaces, where it is impossible to use traditional insulation materials. Sealing all hard to reach parts of construction with unique elastic formulation helps to reduce cold bridges in complex structures and also to reduce the risk of cold bridge appearance due to possible movements in the construction.
