Abstract

A fire resistant frame structure for windows, doors, facades or glass roofs, includes a metallic structural element for connection to at least one other metallic structural element to form a frame. Secured to the outside and/or inside of the frame are slabs of adsorbent material which retain a high water content and exhibit heat absorbing and hydrophilic properties. The slabs of adsorbent material react or are activated at a certain temperature level to release their water content in order to cool the frame.
