RIGID INSULATING PANEL

摘要

The invention relates to a rigid insulating panel comprising a core plate, and two outer plates disposed at opposite faces of the core plate, wherein: the core plate is formed from polymeric foam composite material comprising a polymeric foam and man-made vitreous fibres produced with a cascade spinner or a spinning cup, wherein at least 50% by weight of the man- made vitreous fibres present in the foam composite material have a length of less than 100 micrometres; and each outer layer comprises man-made vitreous fibres and binder and has a density of at least 300kg/m3, such as at least 450 kg/m3, such as around 500 kg/m3.
