Why Foam? – A Better Thermal Insulation
R – value is the most common measure of the insulating qualities maintained by an insulation material; it is a measure of thermal resistance. The greater the R – value, the more effective are the insulation material’s insulating qualities. It is, however, important to note that a manufacturer’s R – value applies only to properly installed insulation, with improperly installed insulation systems being far less effective. Conventional fiberglass batt and blown-in insulation systems may actually perform at a much lower level than indicated by their R – value, depending on how well they have been installed.
The R – value of insulation is substantially diminished with the presence of air leakage. Often, over 40% of a home’s heat loss can be attributed to air leakage.
By using spray foam insulation, installed by a certified FoamWorks professional, the issue of air leakage is eliminated. Spray foam insulation seals your home completely, making it 100% airtight. Spray foam insulation is seamless, making it more efficient than any other material used to insulate a structure. The R – value of medium density spray foam insulation is well over two times that of conventional fiberglass batt insulation, provided the latter is operating under ideal conditions. Medium density spray foam insulation has the highest R – value per inch of any insulation available.
Conventional insulation, such as fiberglass batt insulation, provides a poor barrier against air leakage since it is unlikely to fill in all cracks and seams. When professionally applied by a certified FoamWorks installer, spray foam insulation expands to seal virtually all spaces where air may escape or enter a structure. Drafts are stopped from coming in and air leaking out is eliminated! Therefore, the amount of energy needed to maintain a preferred indoor temperature is greatly reduced, resulting in energy savings. Medium density spray foam insulation acts as an insulation, air barrier and vapour barrier, all in one application.
|Increases Structural Strength
Medium density spray foam insulation increases the structural strength of your home by over 200%. With spray foam insulation being applied into all cavities, a structure will become more rigid and as a result, issues such as settling and creaky floors will be moderated. In addition, spray foam insulation will not settle or shrink and adheres to almost any surface, including wood, metal, concrete and most plastics.
|Improves Air Quality|
Spray foam insulation in your home or business will improve air quality. A continuous, airtight seal prevents pollutants such as dust from invading a structure. Spray foam insulation exceeds all building codes for air barrier systems. In addition, spray foam insulation does not contain any loose particles that may adversely affect indoor air quality. Medium density spray foam insulation is also mould and moisture resistant, a particular concern when insulating a below grade structure such as a basement.
Due to it’s non-porous nature, medium density spray foam insulation resists moisture penetration. By comparison, conventional fiberglass batt insulation is susceptible to moisture infiltration, which can drastically reduce it’s R – value and contribute to mould accumulation. When applied below grade, medium density spray foam insulation can eliminate the problem of damp or wet basement walls.
Using spray foam insulation to insulate your home or business can contribute significantly to reducing the environmental stress faced by the world today. Spray foam insulation ensures that your home will maintain the highest standards of energy efficiency and as a result, reduce the carbon emissions produced by the burning of fossil fuels needed to heat and cool most buildings. In addition, soy based medium density spray foam insulation is composed of renewable vegetable oils and recycled plastics.
The initial cost of having spray foam insulation installed in your home or business is greater than for conventional systems such as fiberglass batt insulation. However, the premium paid to have spray foam insulation installed in a home or business is generally paid back to the building owner in as little as 4 to 5 years in the form of energy cost savings. Heating and cooling costs can be reduced by over 40%! In addition, homeowners may take advantage of several grant and incentive programs offered by federal, provincial and municipal governments. See the Home page for details.
Having spray foam insulation installed in your home or business will reduce outside noise from infiltrating the indoor environment. The noise created by interior mechanical systems, such as HVAC systems, will also be reduced.
