Stone Wool Mineral Fiber Insulation

It features a unique flexible edge designed to compress as the batt is inserted then spring back expanding the batt against the frame studs to give a complete fill.

Stone wool mineral fiber insulation.

The non directional structure of rockwool stone wool insulation is denser than traditional insulation products which helps to absorb acoustic waves and can reduce the intensity and propagation of noise stone wool also effectively reduces airflow and sound transmission while providing higher airflow resistivity for improved sound attenuation. Mineral wool batts for 2 4 walls have an r value of 15 while a standard fiberglass batt made to fit in a 2 4 wall has an r value of 11 or 13. Specific mineral wool products are stone wool and slag wool europe who also includes glass wool which together with ceramic fiber are completely man made fibers. Therefore properly the term mineral wool insulation is a proper subset of mineral fiber insulation.

Mineral wool insulation will not contain any fiberglass. Mineral wool is a stone based mineral fiber insulation comprised of basalt rock and recycled steel slag. Sound absorbent for acoustic comfort. The manufacturing process involves taking molten rock and spinning it while blasting it with cool air.

Slag wool was first made in 1840 in wales by edward parry but no. Mineral wool insulation like that shown in our photograph includes only stone wool insulation insulation made from rock and slag. Mineral stone wool insulation batts are slightly better insulators than the off the shelf fiberglass batts sold at most lumberyards and home centers. It costs about about 25 to 45 more than fiberglass but i feel its benefits more than justify the additional costs.
