Insulated steel roof for industrial building

摘要

The insulation consists of a non-ventilated cover for the steel roof. There can be a panel of semi-rigid glass fibre (7) with a vapour stop wrapping of aluminium (8) against the under surface of a steel cover tub (4). There can be a metal frame formed from C-section material which supports the glass panel against the steel covering. The frame can be clipped to the purlin (6) by a retaining clip of steel wire which is fixed by gripping the metal frame on the purlin. The clip can have a stop (10) at the end to prevent retraction after fixing.
