MINERAL WOOL PANEL

摘要

A single piece mineral wool insulation panel having a height of at least 160 cm and a width of at least 60cm has an upper band located towards an upper edge of the panel, a lower band located towards the lower edge of the panel and a central band positioned between the upper and lower bands, each of the bands extending substantially across the width of the panel. Different densities of mineral wool are arranged at at least the upper and central bands and the panel is particularly suitable for use to fill the cavity of a fire rated door.
