Do your teens insist on blasting their tunes at max volume? We've got you. 140mm Rockwool Flexi Insulation Slab helps to dampen vibrations and sounds, so you can limit unwanted noise and improve comfort levels throughout your home. What really sets 140mm Rockwool Flexi Slab apart from the rest of the Rockwool range is that it has a patented flexible edge, which allows it to be perfectly friction fitted within the supporting framework. Not only that, but it offers fantastic thermal, acoustic and fire performance in one robust insulation solution. 

Made from renewable volcanic rock, these slabs are extremely fire resistant (with a classification of A1 non-combustible) and won’t burn, or release toxic gases or smoke when exposed to high heat. The natural composition of the slabs also means they significantly reduce the carbon footprint of a building. They are suitable for installation between wall frames, roofs, floors and partitions and are considered an effective thermal insulation solution with a thermal conductivity of 0.035W/mK.

Rockwool Flexi Slab Storage & Handling

Rockwool Flexi 140mm slabs have a soft, fibrous texture, very similar to a loaf of bread. Because of this, a serrated blade is all you need to slice through it. We recommend marking the dimensions you need on your slab to avoid mistakes.
When it comes to storage, we advise that you store the slabs inside; keeping them nice and dry.
