INROCK Building Rolls (BR)

logo

logo

INROCK Building Rolls used mainly in pre-engineered buildings (PEB) for roofs and walls to achieve excellent thermal, fire and acoustic insulation. It can be used for both under and over purlin application on the roof.

They consist of fine fibres spun from a range of selected rocks melted at high temperature bonded with a thermosetting resin faced/ laminated with flexible facings like – FSK & ALG etc.

They are light weight, strong, resilient, and easy to handle and cut to suit customer site specific requirements.

Facings:

INROCK Building Rolls are available with flexible facings like – FSK & ALG *
