Pavatherm-Combi insulation board from PAVATEX is manufactured with sustainable woodfibre insulation to be used with Isolair and Pavatherm-Plus to form an efficient insulation system. Many applications for Pavatherm-Combi including over and under rafters are aided by tongue-and-groove edging. As well as being fixed with offset joints under-rafter, Pavatex Pavatherm Combi can be installed directly over rafters to protect them from adverse weather conditions.
