Procheck 125 is a lightweight reinforced polyethylene vapour barrier which can be utilised in a variety of commercial applications. Procheck 125 can be installed where very high moisture vapour resistance is not a necessity but a strong, durable airtight membrane is.
Procheck 300 is a lightweight, reinforced, polyethylene vapour control layer for use within roof and wall constructions to prevent warm, moist air escaping from inside the building and condensing within the insulation. The woven, polypropylene, multifilament scrim reinforcement provides excellent resistance to tears and punctures to withstand tough site conditions and is unaffected by chlorine. Procheck 300’s vapour resistance of Sd 64m makes it the ideal choice for applications such as heated warehouses, schools and shops. Its translucent colour allows visibility to the substructure.
Procheck 500 is a strong reinforced polyethylene vapour control layer with a vapour resistance of Sd 100m, making it suitable for low to medium risk applications e.g. offices, schools & housing. The woven extruded polypropylene multifilament scrim reinforcement provides improved nail tear resistance and robustness to withstand tough site conditions. The sheet is transparent allowing visibility to the substructure to ease the installation. Procheck 500 is the grade utilised by many leading system manufacturers. It is UV stabilised and unaffected by chlorine.
Proctor Procheck Vapour Barrier is available in 3 thicknesses:
