Not just for insulation - it has been used in lino, not in carpets as far as I know.
Asbestos was used in all sorts of materials found in the home. The following list is not complete and should only be used as a guide.
Combined with different quantities of bonding agent, asbestos was used to lag the steel support framework in tower blocks and services such as heating pipes, electrical conduits and ventilation ducts.
In hard-board form it was used on the back of service intake doors, panels at the back of gas fires, bath panels, etc.
In plaster-board form it was used as wall board, especially where there are service ducts running behind.
It was also used as a filler in textured ceiling and wall coverings like Artex, in linoleum floor tiles and artificial slate roofing.
It is found in some storage heaters, ironing boards, brake and clutch linings and garage roofs and walls.
It was combined with cement for use in corrugated roofing, pipework, etc.
