IKO MVP (Modified Vapour Protector) is a self-adhering membrane used over various types of roof decks such as steel, concrete or wood. This vapour retardant is composed of modified SBS asphalt with a top surface of high density cross laminated polyethylene film. This product is designed as a vapour retarder before the installation of the roof system and is not designed as a temporary waterproofing membrane. MVP should not be applied at temperatures below -10°C. IKO MVP is available in either a cross laminated polythene film top (IKO MVP) or sand top surface (IKO MVP SAND) to suit a variety of insulation application methods.
