Composite profiled heat-insulating component - has insulating section forming parallel lengthwise chambers between metal sections with dimensions dependent on degree of insulation required

摘要

The outer and inner profiled metal sections (3,4) are joined by a mating profiled insulating rib (5,6) fitting in grooves in them. The insulating rib comprises two parallel walls (6.1,6.2) joined by transverse ribs so as to form lengthwise chambers (11). Dependent on the degree of resistance required to heat-transfer, the width of the insulating rib is 20,30,40 or 50 mm. The chamber width is equal to or less than the insulating rib width where the chamber height is 5 mm. or less, and wall thickness also regulates the resistance to heat transfer.
