Loose-Fill Cellulose Insulation in Hamilton

Is your home always cold in the winter even though your HVAC is constantly running? If this describes your situation, you may need to consider getting more insulation in your home. One type of blown insulation is called cellulose insulation. Hamilton and area residents most often benefit using this type of insulation in their attics because it’s denser than other types of loose-fill insulation like fibreglass.

Reitzel Insulation thoughtfully prepares each insulation system we install so that it will efficiently provide thermal protection for your home. We offer cellulose insulation as a green, non-toxic thermal solution to those seeking to improve on energy savings as well as their carbon footprint.


Cellulose insulation is a “green” product. It has the highest recycled content of any insulation available, made of roughly 80% recycled newspapers and paper products. While newspapers are flammable, cellulose insulation is covered in boric acid, ammonium sulfate or sodium borate which resists fire, insects, rodents and mould. Cellulose insulation also requires less energy to manufacture than other types of insulation, increasing its environmental friendliness.

Cellulose insulation is approved by all building codes and is effective at all temperatures. It can even perform better as the air gets colder because cellulose retains its insulating value no matter the temperature.


R-value is a number that assess a home’s ability to resist the flow of heat out of the home. Cellulose insulation has the highest R-value per inch of all blown insulation types. However, it is possible to reach even higher R-values by simply piling it deeper.

Cellulose insulation also provides great resistance to air leakage. While all insulation needs dedicated air-barrier systems (like sheathing, caulk and sealants) to perform optimally, densely packed cellulose alone can block air better than fibreglass. This is because the cellular structure of the wood it’s made of is naturally more resistant to the conduction of heat. If your home has had an air-barrier system improperly installed, cellulose is a wise choice for insulation.


Cellulose insulation can be installed in new or existing homes. If you’re looking to retrofit your home with better insulation, cellulose is a great option because existing wall finishes don’t have to be removed during the installation. It’s also great for attic applications as you can apply deep coverage quickly and consistently throughout the space. Cellulose insulation can be effectively dry-blown into existing structures, but it is also effective when damp-sprayed into open wall cavities in new construction.
