Ecological Information

Insulation Refractory’s insulation products are made from glass mineral wool, one of the most environmentally friendly insulants available.


Insulation Refractory’s insulation products are made from silica sand, the earth’s most abundantly occurring mineral and a sustainable, infinite source.


Approximately 50% of the raw material used in the production of Insulation Refractory products is recycled. The recycled material can be post-consumer glass (from housing) or waste glass from flat glass manufacture, which would otherwise go to landfill.


The manufacturing process does not use or contain CFC’s or any other damaging gases.


Packed in corrugated cartons.
