how Celbar recycled insulation works

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 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.

fire rated & recycled insulation

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.

features and benefits of Celbar insulation

  • Ideal for use in houses, schools, hotels, restaurants, entertainment venues and more.
  • Celbar cavity fill sound insulation provides superior sound transfer control.
  • Excellent thermal resistance and provides a high degree of thermal insulation.
  • Naturally safe recycled cellulose fibre. It can be recycled or disposed of as a non-special waste to landfill.
  • Celbar is UL rated for flame spread and smoke developed with the highest available rating.

technical specifications

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!

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.

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. Thermal performance guide filling floor void space, typical < U = 0.25 W/m2K.

Lofts are insulated quickly and efficiently with Celbar cavity insulation.

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.

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.

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.

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.

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

ultimate soundproofing with 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.

For the ultimate soundproofing solution use in conjunction with one of our Oscar Iso-Mount space-saving acoustic hanger range.

“Once again thank you for your prompt response with processing our order for the additional Iso-Mounts. The owners took us by surprise when they asked for the additional area to be done, but they have been so impressed with the results of all the acoustic ceilings that they felt they just had to have it done.”

Derrick Murphy, D&M Murphy Plastering Contractors – Oscar Iso-Mount Type 1 Soundproof Ceiling

“The architect’s solution of fitting high level ‘sound absorbing’ panels produced a negligible improvement. We continued to ‘battle’ with intolerable ‘echo’ making the room unfit for its-purpose.

Following an independent sound monitoring exercise an alternative acoustic dampening application was recommended. Sonaspray was selected. My caretaking staff were greatly impressed by the attention to detail paid by your engineers in the installation procedure. Every surface was carefully covered and the procedure was very professionally completed.

The effect of the application has been tremendous! The hall is a different room and PE, assemblies and lunch-times have become pleasurable occasions compared to the sonic battleground we experienced previously.”

“Yotam Ottolenghi used Oscar Acoustics to render shiny surfaces softly spoken.

Oscar Acoustics are very proud to have been mentioned in the Evening Standard, for the superb acoustic result achieved in the beautiful restaurant NOPI by using our exceptionally smooth Oscar Elite acoustic plaster. Fay continues…

It’s time to talk about noise in restaurants… I don’t always – just sometimes – harp on about the unpleasantness of sound ricocheting off unforgiving surfaces, thumping music shivering your timbers and having to give up on the idea of conversation with dinner. Hiring an acoustic engineer when a new restaurant is planned is an expensive move but two of the most successful operators I know make it top of their list of priorities.”

“Soundproof ceiling is complete… I’ve tested it by powering up a loud DeWalt router in the garage and seeing how loud it is in the room above.

WOW. Can hardly hear it… It really was much quieter than I thought it would be. I can finally use the workshop in the evening when the kids are asleep in the room above. I’ll admit not having done it before I was unsure if it would deaden the noise enough for power tools…but I am blown away by how well it works. Thanks again for your help – much appreciated.”

James Burrows, Home DIY installer – Oscar Iso-Mount Type 2

“The whole transaction has been simple and easy. I fitted the ceiling this weekend and it’s made an instant difference. So much so, that I had to ask the owner of the flat above if he had been using the room above.

I will recommend the product to my friends and will use it on other ceilings in my flat. Keep up the good work.”

Jim Hood, Home DIY installer, Oscar Iso-Mount Type 1 Soundproof Ceiling

“We are pleased to confirm that we have used SonaSpray to good effect in a large sixth form college dining hall in Leicester.

Previously, the hall with its hard, highly reflective surfaces, was an uncomfortable space with high noise levels and poor speech quality/intelligibility. The Introduction of SonaSpray to the ceiling and certain wall panels has reduced the reverberation times, significantly reducing noise levels and improving speech quality. The nature of the material and its application have enabled us to follow and retain the existing plaster moulded features of the ceiling and walls.”
