This is a glass mineral wool insulation roll sized at 4,000mm in length, 455mm in width, and 150mm in thickness. Supplied in a pack covering 3.64m², it is designed for use in masonry separating or party walls, fitting typical wall tie spacings with pre-cut widths for straightforward installation.
On site, the roll is commonly fitted within cavity party walls to help reduce sound transfer and restrict air movement, contributing to improved thermal and acoustic performance of the wall structure. The format allows installers to quickly position insulation between masonry, supporting efficient workflow and effective coverage in residential and commercial builds.
