Question 1

Does an Ottawa attic need baffles when insulated?

Accepted Answer

Yes, attic baffles are required in Ottawa attics — and they're especially critical given our harsh Eastern Ontario climate. Baffles (also called rafter vents or insulation baffles) maintain a clear airflow channel from your soffit vents up to your ridge vent, preventing insulation from blocking ventilation at the eaves.

Without baffles, blown-in or batt insulation migrates toward the eaves and plugs your soffit vents. When that happens, warm moist air from your living space gets trapped in the

Question 2

What is an EnerGuide home evaluation?

Accepted Answer

An EnerGuide home evaluation is an official energy assessment of your home conducted by a certified energy advisor, giving you a standardized rating that shows how energy-efficient your home is and where you're losing the most heat or money.

The evaluation is part of Natural Resources Canada's EnerGuide program, and it's the foundation for most major home energy rebate programs in Ontario — including the Canada Greener Homes Grant and various Enbridge/utility rebates. The advisor visits your ho

Question 3

Are energy efficient windows worth the cost?

Accepted Answer

Yes, energy efficient windows are typically worth the cost in Ottawa's climate, especially if you're replacing windows that are 15+ years old. The combination of energy savings, improved comfort, and increased home value usually justifies the investment over time, particularly given Ottawa's extreme temperature swings and high heating costs.

Energy Savings and Payback

In Ottawa's climate, with winter temperatures regularly dropping to -25°C and summer highs reaching 30°C+, quality windows work

Question 4

What are the best energy efficient home improvements?

Accepted Answer

The most effective energy-efficient home improvements in Ottawa typically provide 15-30% energy savings, with air sealing, insulation upgrades, and high-efficiency heating systems delivering the biggest impact for our climate.

Air Sealing and Insulation form the foundation of any energy efficiency strategy. In Ottawa's harsh winters, heat loss through gaps, cracks, and insufficient insulation can account for 25-40% of your energy bills. Professional air sealing costs $1,500-4,000 and typically

Question 5

How do I reduce drafts in my home?

Accepted Answer

Reducing drafts in your Ottawa home starts with identifying air leaks around windows, doors, and penetrations, then sealing them with weatherstripping, caulking, or spray foam. Most draft issues can be addressed with simple DIY solutions, though some may require professional assessment.

Common Draft Sources and Solutions

The most effective approach is to systematically check your home's envelope. Start with windows and doors - these are the biggest culprits in Ottawa homes, especially older pr

Question 6

Is attic insulation worth it?

Accepted Answer

Absolutely yes - attic insulation is one of the most cost-effective energy upgrades you can make in Ottawa, typically paying for itself within 3-5 years through reduced heating and cooling costs.

In Ottawa's harsh climate with winter temperatures regularly dropping to -20°C or lower, proper attic insulation is critical for maintaining comfort and controlling energy costs. Heat naturally rises, and without adequate insulation, you're essentially heating the outdoors through your roof. The recomm
