It’s estimated that up to 40 percent of a home’s heat loss occurs through the attic, which underscores the importance of ensuring that your attic insulation is up to code. Poor attic insulation doesn’t just mean a less efficient home, but it also means a less comfortable one. As of 2017, the new standard for attic insulation is at an R60 rating and equates to between 17 and 22.5 inches of insulation.
As part of our home exterior renovation offerings we provide attic insulation services to homeowners across the London, Ontario region.
How to Tell if Your Home Needs Improved Insulation
There are many ways to tell if your home requires improved attic insulation. Perhaps the best indicator is the age of your home. Many older homes have less than 6 inches of insulation in the attic, which is far below today’s standard. Other signs to watch for that could indicate a need for improved insulation include:
- High heating and cooling costs
- An overworked HVAC system
- Cold/warm spots in the home
- Ice buildup on the roof in winter
Types of Insulation for Your Attic Roof
Insulation comes in many types, such as loose-fill, rolls and foam board, but the best insulation for attics is spray foam. Not only does it provide a high R-rating, but it can get into many of the nooks and crannies in the attic that other types of insulation cannot. Blow-in insulation is also a viable option for the attic, with materials able to fit into tight spaces. We use industry-leading Owens Corning insulation on many of our insulation jobs.

Frequently Asked Questions Regarding Insulating Your Attic
Is it better to insulate an attic ceiling or floor?
Insulating the floor is standard practice, however it can make sense to insulate the underside of the roof as well. At Davidoff, our consultation includes determining where insulation will work best in your property.
Can you put too much insulation in an attic?
Yes! Too much insulation and your home will be unable to “breathe.” This can lead to moisture being trapped and mold growth. Insulation is important, but so too is proper ventilation. Too much insulation can hinder that.
Should I remove the old attic insulation before adding new?
This largely depends on the type and quality of the old insulation. For instance, if it’s wet or showing signs of a pest or rodent infestation, then it should be removed before new insulation is installed. However, in many cases, new insulation can be installed over the existing insulation.
