Yes, good insulation provides significant energy savings, potentially reducing heating and cooling costs by 20% to 50% depending on the type of insulation and the building's initial condition.
How Insulation Reduces Energy Costs
Reducing Thermal Losses
Insulation creates a barrier that reduces heat transfer between the inside and outside of your building. In winter, it keeps heat inside; in summer, it prevents heat from entering. This reduces the workload on your heating and cooling systems.
Eliminating Air Leaks
Spray foam insulation also seals cracks and gaps through which hot or cold air can escape. These air leaks often account for up to 40% of a building's energy losses.
Average Observed Savings
Residential Buildings
For a typical Quebec home, high-performance insulation can reduce heating bills by 25% to 40%. These savings are even greater for older homes or those poorly insulated to begin with.
Commercial Buildings
Commercial buildings can achieve even greater savings due to their large surface area. Reductions of 30% to 50% in energy costs are frequently observed after professional insulation.
Return on Investment
Quick Payback
Insulation investment typically pays for itself in 3 to 7 years through energy bill savings. After this period, savings continue for the entire lifespan of the insulation.
Investment Durability
Spray foam has a lifespan of over 50 years without loss of efficiency. This means decades of savings after the initial investment is paid off.
Additional Benefits
Improved Comfort
In addition to savings, good insulation significantly improves indoor comfort by eliminating cold spots, drafts, and temperature variations between rooms.
Property Value
A well-insulated home has higher property value. Buyers are increasingly aware of energy efficiency and are willing to pay more for a well-insulated building.
