Harold Orr, whom many consider to be the father of the Canadian R-2000 Energy Efficient Building Program, summed the overall concept using five words:
"Build tight and ventilate right."
In warm or cold climates, inadequate insulation and air leakage are leading causes of energy waste in most homes or buildings. Since Igloo Cellulose is a loose material, it has the benefit of filling voids and eliminating air pockets common with other insulation materials. Density, which is important in reducing air infiltration and increasing effective R-Value, is higher with cellulose than with other types of loose insulation. As a result, Igloo Cellulose performs better by reducing air conditioning or heating costs from 30% up to 50%.
Once the energy savings have paid for the installation cost, energy conserved is money saved--and the annual savings will increase when utility rates go up.
| What is the R-Value?
The effectiveness or level of performance of an insulation material is measured by its Thermal Resistance or "R - Value". R-value requirements of a house or building will depend on climate conditions, the type of heating used, building design, etc. As an R-value increases, the transfer of heat resistance increases. Insulation added in attic, walls, floors, basement will result in maximum energy savings.
Higher R-Value per Inch means greater resistance to conductive heat transfer and Igloo Cellulose Insulation has a higher R-Value per inch than fiberglass.
Note : Some insulation materials are marked with both "RSI" (Resistance System International) value) and "R" values. RSI values indicate thermal resistance in metric terms, while R values measure it in the imperial system of measurement. Be careful not to confuse the two.
