SUNROCK RIGID BOARD is another new addition in the product line. Rigid boards are manufactured in accordance with ASTM C 612 as well as other standards.

SUNROCK RIGID BOARDS are suitable for operating temperature to 750°C.These are high density stonewool boards made from high quality stonewool fibres bonded with thermosetting resin.

SUNROCK RIGID BOARDS are high density thermal boards with high compressive strength.

SUNROCK RIGID BOARDS are water repellent, non-hygroscopic, non-capillary and does not absorb any moisture from air, moisture has no effect on stability of slabs.

Rigid boards are also suitable for thermal, acoustic as well as fire resistance requirements.

SUNROCK RIGID BOARDS are generally used at the places demanding higher compressive strength and high sound impact, places such as exterior walls and flooring etc.
