Rockwool Building Roll

Rockwool Building Roll About

The Rockwool Building Roll is widely used in pre-engineered buildings for walls as well as roofs for providing them outstanding acoustic and thermal insulation. It serves its utilization for both over and under purlin applications on the roof. The fibers of the Rockwool in building roll are uniformly distributed and fine that help in ensuring excellent as well as uniform thermal resistance. The stable rock wool fibers bonded with thermosetting resins are lightweight, sturdy and resilient. It is available with FSK facings that gives an effective vapor barrier.
