Slab Insulation Cold Deck - Under Soffit
LAMBDABOARD® serves as the optimal solution for under soffit insulation, particularly in retrofits, with its continuous manufacturing process featuring a closed-cell PIR core securely bonded to two flexible substrates.
Where construction, design and / or cost implications prohibit the installation of an inverted roof insulation system, the requirement for insulation is met by fixing IsoBoard to the under soffit surface of the slab as a ceiling.
