Cellulose Fiber


Cellulose fiber is an excellent thermal and acoustic insulant that can be used in attics, walls, ceilings or floors, according to your specific needs. This insulating material can be installed as new buildings are going up or during the renovation of older constructions. Cellulose fiber is increasingly becoming the first choice of building contractors.


Cellulose and thermal insulation

Optimal thermal insulation requires a material that is flexible and dense, capable of stopping air leakage or infiltration. Why is cellulose such an ingenious choice? Because it comes in small, flexible particles that can be blown into attics or injected inside walls, floors or ceilings.


EIt blankets obstacles (such as plumping fixtures or framing) perfectly, and easily fills in hard-to-reach places, thus eliminating air pockets that have been left unprotected against air leaks or infiltration by other types of insulating materials. In the case of existing constructions, cellulose particles can be blown in on top of existing insulants to fill in any spaces where the latter lost their efficiency. Thus cellulose allows for savings ranging from 30 to 50 % on heating and cooling costs.


While insulating materials' efficiency is measured according to several variables, like climatic conditions or heating systems, cellulose - a non-heat conducting material - is much more efficient than many other products on the market.


Cellulose and acoustic insulation

When used as acoustic insulation, cellulose fibers act as an absorbing barrier which greatly contributes to reducing and preventing sound propagation. Whether you choose this product to enhance your quality of life by soundproofing your condo, or for professional purposes by including it in the design of a recording studio, for example, you will find that noise levels remain quite low.


The National Building Code of Canada requires a minimal STC rating of 50 (sound transmission class); cellulose injected at a density of 3.0 lb/ft 3 offers an insulation quality exceeding STC 56.



Whatever the type of insulating material you choose, optimal performance calls for installation by people with the necessary expertise using the right techniques. Isolation Ippersiel's technicians are properly trained to provide you with the comfort you want; our know-how and specialized equipment guarantee you a job well done, compliant with industry standards.


To insulate the walls of a new construction, we start by installing a membrane, specially designed to let the air out while limiting dust emissions, on the building's frame studs standing every 16 inches; that allows us to attain an injection density of up to 3.5 lb/ft 3 . Once the wall is entirely covered with the membrane, the cavity is filled will cellulosic fibers, which are then compacted to the required density (usually 3.0 lb/ft 3 ) - for undoubtedly superior results.


To insulate the walls, floors or ceilings of an existing structure, we drill small holes, inside or outside the building, according to our clients' wants or needs. We then inject and compact the cellulosic insulant through the holes, which we carefully plug once the filling process is over.
