Rockwool 8# Density Foil-Faced Stone Wool Insulation Mineral Wool Panels, Batts - 3", 2'x4' (5) per Pack, Pro-Grade Acoustic Soundproofing, Thermal Barrier & Fire Block

Easier than old school pink insulation. Cut easily with a box cutter. Easy for patches and or odd spaces

Very easy to work with. Cuts with ease but sturdy enough to stay where you want it.

The insulation panels do not have foil on them as advertised. That being said, they did a great job of quieting down a small office space (laid on top of ceiling drop tiles) that has a loud HVAC run above it. Easy to cut and place.

This item was delivered in a timely manner, neatly packaged and all together. I would definitely recommend Burning River Buys to anyone looking for insulation. This company was very professional in sending their packages.
