Product
Crown FactoryClad Roll is a flexible, lightweight, non-combustible,
resilient glass mineral wool quilt. It is manufactured in long
lengths and has an exceptionally high tear strength, making it
particularly suitable for use in the walls of profile metal clad
buildings.
Typical Construction
Profiled metal external sheets, vapour check plasterboard supported
in a framework suspended from purlins, and quilt insulation laid on
the back of the plasterboard lining panels. All quilt edges butted
tightly. There is a ventilated airspace of up to 150mm between the
insulation and the external skin.
