What insulation Should you Use in Your Attic?


Attic insulation is the most efficient way to keep heat in during the winter and cold air during the summer. No matter how big or what material your house is made of, it needs a well-insulated attic to keep the temperature stable and the energy bill low. That final line applies to you in bold print and all caps if you reside in a place with especially harsh and snowy winters.

Here, you see the compiled and essential information about attic insulation pricing, products, preparation, and installation right here. Continue reading to learn about crawl space insulation installation services in Toronto and what types are available.

What Are the Different Types of Attic Insulation?

Attic insulation comes in various forms, including a blanket, spray foam, radiant foil, and foam boards, each with its own set of advantages and disadvantages. Have a look at these types below-

Insulation blankets

Blanket insulation is one of the most frequent types of insulation for walls and attic floors; however, it should not be used in open spaces since the fiberglass particles can harm your home’s air quality. Cut the thick insulation pieces to fit snugly between gaps in wooden frames or around pipes, wires, and other obstructions.

While this is one of the cheapest and easiest types of insulation to install, it isn’t as effective as spray foam insulation. Wear a respirator mask and protective gloves when installing blanket insulation to avoid irritating your lungs and skin.

Foam Spray

The most common type of attic insulation is spray foam. Use it to plug gaps in existing walls and combine them with blanket insulation to insulate edges and corners better. It is the most expensive variety and might be difficult to remove; yet, it is the most effective alternative for insulating your home against heat and cold air transfer.

Spray foam is formed of liquid polyurethane that expands and hardens into a solid foam when sprayed into the hollow of your wall or attic. If you’ve never used spray foam before, consider having it installed by a professional to guarantee your home is appropriately secured.

Radiant Foil

Radiant foil insulation is more prevalent in warmer climates because it is meant to deflect heat away from your home. It operates by reflecting light via a foil barrier connected to kraft paper or polyethylene bubbles. Because the bubbles form a pocket of air, which decreases the pace at which heat can pass through the substance, inhibiting heat transfer across the barrier.

Radiant foil, on the other hand, radiates heat rather than reducing it. Because of this discrepancy, radiant foil insulation cannot be measured using the same parameters as blanket, spray, or foam board insulation. Radiant foil is typically the most cost-effective type of insulation.

Foam Board

Foam board insulation comprises polyurethane, polystyrene, or polyisocyanurate and is inexpensive and simple to install. Foamboard sheets can be trimmed to fit snugly between studs or joists in the attic ceiling. Foam boards are not as popular as blanket insulation since they are less effective at insulating.

Because solid foam does not absorb much moisture, foam boards do not promote moisture collection and mold growth like blanket insulation can. Instead, it dries in a short amount of time. If you want foam board then, search for a crawl space insulation installation service in Toronto.

Loose-Fill Insulation

Installing loose-fill insulation in attics with limited headroom and many impediments such as vents and cross-beams is ideal. It is available in fiberglass, cellulose, and mineral wool and can be blown over existing insulation. Cellulose is the most efficient substance, with an R-value of 2.2 to 3.8 per inch.
However, it can mold if exposed to moisture. You can buy this type of insulation online, spread it by hand, or you can hire an easy-to-use machine that blows it in place for around $100 per day.


Cellulose insulation is typically made of wood or recycled paper, and it is frequently marketed as a green product. Despite having more recycled content than other types of insulation slightly, cellulose does not pass a comprehensive “green” examination of its environmental impact. This product is often blown-in and is a very cost-effective installation. If you want blown-in insulation in Toronto, cellulose can be a good option.


Another often used attic insulation product is fibreglass. The material is constructed of fine glass fibres and offers good performance at a reasonable price. You can find a big list in Ontario for fireproofing companies offering fibreglass insulation for the people. However, effective air sealing throughout the attic is still required because the installation does not block circulation.
