Parafon® Buller
Parafon Buller is a genuine classic with a wide range of applications in industrial environments or where effective and fireproof sound absorption needs to be achieved. The mineral wool’s good fire properties – which mean that it retains its shape even at very high temperatures – and climate properties including sound absorption make it particularly suitable for tough environments such as industrial premises, warehouses, sports facilities, multi-storey car parks and similar. Parafon Buller is available in a variety of colours, thicknesses and sizes.
