45KG DENSITY INSULATION SLABS

45kg/m³ acoustic insulation slabs are the low level insulation density slabs available either from Rockwool or Knauf brand. Although, those slabs still have higher density than other forms of insulation unlike thermal insulation which is lower in density and supplied in rolls. Rockwool RWA45 or Knauf RS45 is named after its density properties in that it has a density of 45Kg per cubic meter. When you normally use rolls for floors, slabs are normally for walls. In fact, it’s the density that marks out this type of soundproof insulation from other slabs of insulation. 45kg/m³ density slabs are ideal for use in residential buildings such as home offices, studies, bedrooms, bathrooms, media and gaming rooms. The solution is suitable for application in walls, floors and lofts to control home acoustics. It is important to remember that doubling up on thicknesses will not offer double the level of soundproofing. 45kg density slabs can be supplied either in standard unfaced 1200mmx600mm size or foil backed on both sides. Unlike unfaced slabs, foils faced boards offer great fire performance classified as Euroclass A1. These odorless, non-hygroscopic, and rot proof slabs are free of CFCs and HCFCs and will not encourage the growth of fungi, mould or bacteria. 45kg range slabs include the following readily available product thicknesses:
25mm ǀ 30mm ǀ 40mm ǀ 50mm ǀ 60mm ǀ 75mm ǀ 90mm ǀ 100mm 

DENSITY EXPLANATION

Generally speaking, kg/m³ is the weight of the slabs if they were manufactured in a block of one metre cube (1m x 1m x 1m). In order for them to be identified, they are given a density rating which refers to the weight of a metre cube, displayed as kg/m³. Acoustic insulation is available in a variety of densities which range from 45kg up to 100kg per slab. The greater the mass is, the harder it is to vibrate this material, thus the better the insulating property will be. Therefore, it is better to choose dense and heavy material.
