Insulation R-value dictates the amount of airflow restriction that a certain level, type and or thickness of insulation can provide. R-value can dictate how quickly your insulated space will lose heat and let cold air in, or the opposite depending on the property location and seasonal weather. R-value truly plays a large role in selecting the ideal type of insulation for your property.

The proper R-value is imperative to receiving the ideal benefits from your residential or commercial insulation installation.  Too high of an R-value can cause for stuffy air and opportunities for moisture to build in your home or business. Too low of an R-value can result in insulation that struggles to accomplish its heating and or cooling goals. Always contact a professional to receive the insulation type with the perfect R-value for your home or business.

A common question among home and business owners who are looking into insulation projects and professional services is, “what is R-Value”?  R-value is the measure of heat flow resistance in specified type and thickness of insulation. Different areas in properties, as well as different property locations, can both dictate the relative insulation R-values required to adequately retain heat or cool air in your home or business. Make sure your insulation selection will provides the sufficient R-value for your needs.


Attics are often very cold and non-utilized spaces in homes and businesses alike. Much of the heat in your residential or commercial property can escape through the attic without adequate insulation. And R-value of R-49 or even more is often required in Calgary attics, due to the cold average temperatures in the city.  This means that for a blown in attic insulation that carrying an R-value of 3.5 per inch, you will need roughly 14 inches of insulation.

Exterior walls face large amounts of winds and cold air from the outside climate. Utilise wall insulation to make sure your home or business stays warm through Calgary winters. Wall insulation is limited in size by the studs in the wall, but still is very important to efficiently heat and or cool your property. Insulation types, such as spray foam insulation, that can have very high R-values and thus do not require a very thick or broad piece of insulation to accomplish the property heating goals.
