The Frinorm door leaf blanks Iswood® are suited for all kinds of applications. They were tested and meet the demands of the highest climate category. The door leaf blanks have excellent thermal insulation properties and are very stable with a low surface density. The centre core multilayer sandwich board consists of poplar plywood and high-quality pressed cork. The frame of the door leaf blanks is fabricated from massive larch wood and does not contain any metal stabilisers. Aluphenol is used for the surface cover board, a high-pressure composite material on the basis of duromer high-pressure laminates (HPL). This is vapour-proof and has good heat deflection properties. The aluphenol board can be veneered, lacquered or coated.
