Insu® Foam is an extruded polystyrene insulation foam board. It is formulated from polystyrene blowing agents, fire resistance chemicals, stabilizer compound and colouring agents, to achieve excellent insulating, fire and moisture resistant properties coupled with high compressive strength to weight ratio.
The extrusion process produces a uniform thickness throughout the board, resulting in a continuous even surface.

It is used as a heat insulation material for both metal and concrete roofs, walls of buildings and structures in a hot or cold environment. With its high compressive strength to weight ratio, it is also used as “filler” in casting concrete slabs, allowing designers to reduce dead load on building structures
