A good understanding of DIY is all you need to install our DFM slabs in your home. You can cut them to size with a hand saw or sharp knife. We recommend cutting them slightly larger than your opening to allow a friction fit.
The DFM range comes with a choice of density; this is how compact the slab is (not the weight). The range in density is kg/m³ from 45, 60, 80, 100 and 140. The easiest way to understand which one to choose would be to assume the higher the density, the better the overall level of soundproofing.
We recommend the 60kg/m³ as this offers the best sound insulation for the money spent. If you want to discuss the best solution for your space, don’t hesitate to get in touch.
