Soundproof Spray

celbar spray-on soundproofing

Soundproof & Thermal Insulation for walls and ceilings

Typically used as the thermal acoustic cavity filler in walls or between floors either in conventional rigid construction or in isolated systems e.g. Iso-Mount space saving acoustic ceiling hanger.


Celbar recycled acoustic insulation can either be sprayed into the cavity before the void is closed OR where a void is already closed it is blown by hose through holes to improve the acoustic insulation of walls and/or ceilings. When two layers of plasterboard are used, the Celbar recycled acoustic insulation is blown in before the second layer is fitted.


Celbar recycled acoustic insulation provides superior sound transfer control demanded by designers, owners & occupants.

Older properties with ornate ceilings benefit with Celbar recycled acoustic cavity insulation blown into the ceiling void reducing noise from rooms above. It is blown into the void through small holes cut into flat areas of the ceiling and repaired afterwards or if major refurbishment is taking place it is filled from above by lifting floorboards.

Environmentally Friendly Soundproof Spray

A Green Product

The recycled acoustic insulation fibre is organic cellulose derived entirely from recycled macerated paper and treated with a borax compound to protect against fungus, insects and rodents. It also has fire protection built in. Celbar cavity fill insulation has excellent thermal resistance and provides a high degree of thermal insulation.  Recycled material and a low manufacturing energy requirement combine to produce probably the most environmentally friendly material used in building construction, low CO2.


Low Embodied Energy - Good for the Environment - Easy Disposal - Recyclable
Naturally safe recycled acoustic insulation. Reconstruction of a building may necessitate removal of Celbar recycled acoustic insulation fibre. It can be recycled or disposed of as a non-special waste to landfill - your local authority waste disposal will give advice on recycling.  Incredible!
