25mm/60kg/m³ DFM Acoustic Insulation
For the most effective soundproofing solution for your space, you’ll need some acoustic insulation Dense Fibre Matting (DFM). DFM acoustic slabs are one of the best ways of improving sound insulation in a room. If you are trying to soundproof a room, DFM would be essential to insulate inside the cavities.
For floors and ceilings, insert the DMF between joists and walls, and combine it with soundproof panels for the most effective noise reduction. As well as acoustic properties, DFM is a non-combustible product with a class ‘o’ fire rating.

- Install between timber/metal studs or between floor/ceiling joists
- Cut to size and friction fit
- Airborne sound insulation
- Variety of thicknesses and densities
- Non-combustible product
- All slabs are 1200mm x 600 mm
- Thickness mm 25, 50, 75 & 100
- Density kg/m³ 45, 60, 80, 100, 140
DFM slabs are simple to fit. Cut the slabs slightly larger than the opening, and friction fit inside the cavity. Cut slabs to size using a hand saw or a sharp knife.
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. Get in touch if you’re unsure which option is best for your soundproofing project.
