Attic Insulation
Superior attic insulation from O'Dwyer Insulation and why attic insulation matters for your home:
Lower Utility Bills
Proper attic insulation reduces heat loss in winter and heat gain in summer, meaning your HVAC system works less—saving you up to 20% or more on your energy bills each year.
Improved Comfort Year-Round
Say goodbye to drafty rooms in the winter and overheated upper floors in the summer. Quality attic insulation helps maintain a consistent indoor temperature throughout your home.
Prevention of Ice Dams
Good insulation paired with proper ventilation helps prevent ice damming, which can cause costly roof and interior water damage during Ontario’s winters.
Increased Home Value & Resale Appeal
Energy efficiency is a top selling point for homebuyers. Well-insulated homes are more attractive on the market and may even qualify for rebates or energy efficiency programs.
Noise Reduction
Insulation doesn’t just regulate temperature—it also acts as a sound barrier, reducing noise from outside and between floors for a quieter, more peaceful home.
Protects HVAC Equipment
When your home retains heat more efficiently, your furnace or AC doesn’t have to work as hard, helping extend the lifespan of your heating and cooling systems.
How R-Value Affects Home Insulation
and Energy Efficiency
Insulation works by resisting heat and cold flow—and that resistance is measured by R-Value. The higher the R-Value, the better your attic can retain warmth in the winter and cool air in the summer, helping lower your energy bills.
In Ontario, recommended attic R-Values have increased over the years—from R-32 in the early '90s to R-50/60 today. If your home is over 25 years old, chances are your attic insulation is outdated or has settled, reducing its effectiveness.
Adding a top-up of high-quality Owen's Cornings blown-in insulation is a simple way to meet today’s standards and improve comfort year-round.
