Attic Insulation
Attic Insulation Services for Year-Round Comfort
MacLeod Spray Foam Insulation can help you save money on energy costs with our attic insulation in Ottawa and surrounding areas. A well-insulated attic significantly affects how your home or business feels and how much you spend on heating and cooling. Spray foam creates a tight seal that keeps outside air where it belongs and holds your heat or cool air inside, meaning you experience less draft. As a result, you can increase comfort while lowering your bills. We aim to treat every attic as part of our home with honest advice, a clean installation, and tangible results.

Why Spray Foam Works Best in the Attic
Spray foam insulation stops energy loss at the top of your home, where it matters most. It keeps your property comfortable in any season by retaining warm air in winter and keeping out hot air in summer. Here’s why it’s one of the smartest upgrades you can make in your attic:
- Seals Every Crack and Gap — Spray foam expands on contact to block air leaks in hard-to-reach spaces. This feature creates a tight thermal seal that other materials can’t match.
- Cuts Down on Energy Bills — Less heat loss means lower heating and cooling costs. Over time, the savings can help pay for the insulation itself.
- Protects Against Moisture Damage — Spray foam repels moisture, reducing the risk of mold, mildew, and rot in your attic. It also adds another layer of protection for your roof structure.
- Lasts for Decades — Spray foam doesn’t settle, sag, or break down over time. One proper installation gives you long-term performance without extra upkeep.
What Are the Benefits of Attic Insulation?
A properly insulated attic offers real value for both comfort and cost savings. So, whether you own a home or manage a building, insulation helps you get the most out of your space. Here are the benefits you can expect from attic insulation:
Insulation keeps heated and cooled air inside your home. This barrier reduces how often your furnace or AC must run to regulate temperature.
Insulated attics help prevent hot and cold spots in your home. Rooms stay more consistent and comfortable throughout the year.
Professional attic insulation can mean fewer HVAC system repairs and replacements. Lower demands on your heating and cooling systems enable them to last longer.
Attic insulation adds a sound barrier between your home and the outside. It helps reduce outdoor noise, such as traffic or weather.
Energy-efficient homes are more attractive to buyers. Attic insulation is a smart upgrade with a lasting impact.
