Recycled & fire rated

Properly insulating and air sealing your home is one of the quickest, easiest and most cost effective steps you can take to significantly reduce your heating bills.  Celbar insulation for residential and commercial applications is an energy saving cellulose spray insulation made from high quality, recycled paper.  Celbar ceiling, loft and wall insulation effectively reduces heat and sound transfer by creating dead air spaces between and within its fibres. 

Celbar is UL rated for flame spread and smoke developed with the highest available rating.  A specially formulated borate compound gives Celbar fire resistant insulation a Class 1 fire rating.  Additionally, Celbar thermal sound insulation provides a barrier that resists penetration by fire.

How Celbar works

Celbar sound insulation can either be sprayed into a ceiling/wall cavity before the void is closed OR where a void is already closed it is blown by a hose through holes to improve the acoustic insulation of walls and/or ceilings.  This seals any holes and cracks in the wallboard, around electrical outlets, plumbing and other irregularities so there are no compressed areas or voids to allow sound leaks or air infiltration.  When two layers of plasterboard are used, the Celbar sound insulation is blown in before the second layer is fitted.


Celbar vs man-made mineral wool

When packed together, tests have shown that Celbar sound insulation is both thermally and acoustically more effective than man-made mineral wool. Consider a wooden rod versus a glass rod over a heat source.  The glass rod conducts heat readily, the wooden rod doesn't.  Traditional mineral wool insulation is a mass of small glass rods, additional insulating power is lost when it is compressed and it is umcomfortable to work with.

Lofts, ceilings, walls and floors are insulated quickly and efficiently with Celbar sound insulation.


Ceiling soundproofing with Celbar & Iso-Mount

Celbar is used as a cavity filler in walls and between floors either in conventional rigid constructions or with isolated ceiling systems e.g. combined with one of our Oscar Iso-Mount range for ultimate ceiling soundproofing performance.

Superior sound transfer control

Celbar cavity fill sound insulation provides superior sound transfer control demanded by designers, owners & occupants.  Older properties with ornate ceilings benefit with Celbar acoustic cavity fill 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.

Acoustic performance guide filling floor void space, typical overall improvement better than - 9dB

A simple wall construction of 63mm thick metal studs lined with 12mm plasterboard on each side was tested:
[a] with no sound control material used - Result 31 STC
[b] with mineral wool sound barrier batt - Result 33 STC
[c] with 38mm of sprayed Celbar - Result 49 STC

A green product

The 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.

Recyclable

Naturally safe recycled cellulose fibre.  Reconstruction of a building may necessitate removal of Celbar cavity fill 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. 

Typical Celbar applications

Party walls, between floors & plumbing, silencing water noise, schools, hotels, apartments, restaurants, pubs & entertainment venues, offices.

The Holiday Inn, Sheraton and Intercontinental Hotels use Celbar cellulose insulation to ensure client comfort.

Health & safety

There are no known serious risks to health associated with Celbar recycled acoustic therma insulation.  It is non-carcinogenic and any small release of fibre during installation or subsequent maintenance work is not hazardous or considered a ‘Health and Safety’ risk.  Celbar cavity fill insulation is not subject to legislation applicable to mineral or vitrified fibre. 

As an added bonus, Celbar cavity fill insulation is non-itchy!
