Geographic availability
Europe
Origin / Location of manufacturing / Processing plant

Application and typical uses of the product
Multitherm is mostly fixed to the external face of timber frame walls (sometimes used internally) in order to provide enhanced insulation values, reduced thermal bridging and ensuring that the external side of the wall is moisture vapour diffusion open (breathable). The Multitherm is always applied with a cavity and cladding externally. Multitherm is also used extensively in Cross Laminated Construction (CLT)
