Cellulose fibre maintains an almost constant R-Value over the full range of densities at which it can be installed, whereas mineral fibre products suffer dramatic losses in R-Value as the installed density decreases.

Thermal Resistivity Properties of Cellulose Fibre
01
THERMAL RESISTIVITY
Cellulose fibre provides greater energy savings
Why is it Important
Canadian homes and buildings can experience extreme temperature changes from season to season.

This video shows the effect of reducing heat loss with blown in cellulose insulation. The video shows actual thermal images isllustrating the difference in temperature of poor insulation vs. cellulose insulation upgrades.
How it works
Wood fibre is organic and hollow
Cellulose fibre is naturally resistant to heat loses through conduction and convection, because it is organic and it is hollow.
The organic material makes cellulose fibre a poor conducter, and the wood fibre is also hollow so it entraps air within its structure.
The product also has the unique ability to perform better under extreme cold temperature. Specifically, it has been shown that R-values can increase as much as much as 7% under extreme cold conditions whereas fibreglass can lose as much as 21% under the same conditions (ASHRAE “Handbook of Fundamentals”, BNL 50862).
Similarly, cellulose fibre’s basic R-Value is superior to mineral fibre in the colder or hotter temperature range and makes it a preferred insulation for reducing summer cooling and winter heating costs.
Cellulose fibre maintains an almost constant R-Value over the full range of densities at which it can be installed, whereas mineral fibre products suffer dramatic losses in R-Value as the installed density decreases.
More Technical Information
Thermal Resistivity
Cellulose Insulation provides greater energy savings over other products.
Convection Properties
Cellulose fibre, due to its perfect fit and greater density, inhibits air movement.
Acoustical Properties
Superior properties for improving noise suppression in wall, floor or ceiling construction
Moisture Resistance
Cellulose fibre has the unique ability to slowly absorb and dissipate excess moisture.
Fire Resistance
Cellulose fibre will not melt or degrade when exposed to flame or high temperatures.
Borate Additives
Cellulose fibre insulation is treated with a carefully controlled blend of borate powders.
