Air Sealing of Spray Foam Insulation

Wondering why your insulation isn't working? Chances are, there's nothing wrong with your insulation. But there's an area you've overlooked: the air gaps.

Air gaps can form in the frames of windows and doors and ducting wiring and plumbing. In addition, larger cracks can occur due to faults in the building's structure. And while many people don't even realize it, air sealing your home is just as important as insulating it.

And what better way to seal the gaps than to apply spray foam insulation. It's quick, easy, and cheap. And the insulation will last you for decades to come.

Why Should You Air Seal Your Building?

It may seem like a trivial question, but lots of people don't even know the importance of air sealing your building.

Air leaks between your walls and floors can cause significant disturbances. For one thing, they can render your insulation completely useless. In addition, when there is an air leak in your room, variables like temperature, humidity, and air quality get messed up.

You can cut down on costly heating and cooling solutions by installing adequate air sealing in your home and office. Spray foam insulation will keep your building insulated from heat, noise, humidity, and air pollutants.

But there's another hidden benefit of spraying foam insulation, especially of higher density: building support. That's right. High and medium-density spray foam offers some level of support to the walls and floor.

Medium-density Spray Foam Insulation Benefits

● It doesn't get wet and protects your house from moisture.

● Prevents temperature fluctuations.

● Easy and convenient to install in your home.

● Better sound-proofing.

● It's relatively cheaper.

● It's a green option for the environmentally conscious.

● Strengthens your building walls and ceiling.

● Retains its effectiveness for years to come.

● Improves the quality of indoor air.

Choosing The Recommended Application

Medium-density spray foam is the best choice for insulation, but how do you apply it? Contrary to popular belief, the application isn't the same with every barrier.

Decide where you want the insulation. Ideally, it should be on every wall, ceiling, floor, and basement/crawlspace. The application will depend on what part of the building you want to insulate.

Additionally, the style of the barrier influences the type of spray foam insulation you can use. For example, do you have a cathedral or a vented attic? Do you have the floor over your crawlspace or not? These factors will decide what type of application you need.

But since spray foam insulation is meant to insulate the building, climate and ambient temperature matter too. ASHRAE defines 8 climate zones in Canada, with Toronto falling under Zone 6.

Why Medium-Density Spray Foam?

The density of the spray foam you use essentially depends on what type of application you need. In this regard, there are three densities of foam: high, medium, and low.

Medium-density foam is highly recommended for interior wall cavities and unvented attics. Additionally, it's best for continuous insulation. It's also a good choice for many climates. But that's not all. Since medium density foam is thicker than low-density foam, it can be applied where you want a higher R-value.

This type of foam is also ideal for soundproofing the house, perfect for homes, offices, hospitals, and libraries. However, medium-density foam isn't exactly moisture-proof and can be affected by rain and storms.

Maintain A Comfortable Living Space with Spray Foam Insulation

Why you're still feeling too cold in the winters? Did you install the insulation wrong? Unlikely. But what you did do was install it in the wrong places. Air gaps caused by cracks and openings can essentially undo all the hard work your insulation did. Such air gaps are common around the frames of windows and doors.

Your first step to solving an air tightness issue is to assess the airtightness of the room. There's also the home energy audit which determines the energy requirements of your building.

The next step is to fill in the gaps. One option is to caulk and weatherstrip the places that leak air, such as doors, windows, plumbing, wiring, and ducting. However, this method will rarely work for larger gaps leftover during construction.

And that's what spray foam insulation is for. Spray foam insulation keeps your home and office feeling cozy. It fills in gaps in the cement that would otherwise allow unwanted airflow.
