Don’t let high energy costs and insufficient insulation affect your property

We specialize in 2lb medium density closed cell SPF (Spray Polyurethane Foam) insulation, providing our clients with customized solutions that meet their specific needs.

At our insulation company in Toronto, although we offer various forms of insulation installation, we understand that SPF insulation offers several advantages over more traditional insulating materials. It provides superior insulation performance, reducing energy consumption and costs, while also adding structural integrity to the building. SPF also helps to prevent rodents and pests from entering the structure and inhibits the growth of mold and mildew, ultimately contributing to the overall health and comfort of the occupants. For over 2 decades, our Toronto insulation company has been proudly serving Toronto, Markham, Richmond Hill, Newmarket, Barrie, Muskoka, Scarborough, Oshawa, Brampton, Mississauga and the surrounding cities in Southern Ontario.

Our Drywall and Insulation Services for Toronto Properties

At Exotherm Spray Foam Systems, our company offers all types of Toronto insulation and drywall services for residential, commercial, and industrial applications. Whether your project requires a popular batt or rolled insulation, SPF insulation, or a combination of the two, we’ve got you covered!


Spray polyurethane foam, or SPF, insulation is a special spray-applied plastic that fills any gaps and cracks, effectively insulating the area. At Exotherm Systems, we offer 2lb medium-density closed-cell SPF insulation, which has the highest Long Term Thermal Resistance of any insulation product available on the market today. Closed-cell SPF insulation is incredibly effective in making homes and commercial spaces more comfortable and energy efficient due to its ability to resist unwanted airflow through cracks, seams, and joints.


Similarly to roll insulation, batt insulation presents “blankets” of insulation material like fiberglass or mineral wool, with or without additional facing. However, batt insulation is pre-cut into flat pieces or batts, which can then be installed between a home’s studs, joints, and rafters. Batt insulation is another budget-friendly option for insulating unfinished walls, floors, ceilings, and attics.


Rolled blanket insulation takes the form of continuous blanket rolls that are made up of small insulating fibers. These blankets are budget-friendly; they can be easily installed in ceilings, floors, and unfinished walls by fitting them between joints, studs, and beams. At Exotherm Systems, we offer fiberglass and mineral wool blanket insulation, with an option to choose between lined and unlined blankets.


Drywall, or gypsum board, is an incredibly common building material used for lining interior walls and ceilings. Made of gypsum and other materials, drywall is placed in between a facer and backer paper and mixed with special fibers to increase its moisture and fire resistance. At our insulation company in Toronto, we offer quick and budget-friendly drywall installation and replacement services to help you stay on track with your renovation project.


Properly insulating the attic is key to keeping your home as energy-efficient as possible. At Exotherm Systems, we offer two types of attic insulation: blown-in loose-fill insulation and a hybrid of blown-in and SPF insulation. With the first option, small particles of foam, fiber, or other materials are “blown-in” the attic, perfectly conforming to the available space. With the hybrid insulation, a layer of spray polyurethane foam is first applied to the attic, followed by a layer of blown-in insulation.


Is your insulation old and deteriorated? If you notice signs of moisture, mold, or animal debris in your existing insulation, it may be time to replace it with a new, more efficient product. In other situations, an over-insulated attic may require insulation removal in order to restore proper air ventilation. In addition, old insulation must be removed in case you are planning to install spray foam insulation or SPF/loose-fill hybrid insulation.


Blown-in loosefill insulation is commonly used in homes for its efficiency and low cost, it is more easily installed in hard to reach places than any other insulating material. 


Living in a moldy home can cause serious respiratory problems and other health issues for you and your family. We are happy to offer comprehensive mold remediation services, which include everything from mold inspection and testing to mold removal and sanitizing. Don’t let your mold problem get out of hand, - give us a call today!

Savings on to you

Reduce heating and Cooling costs

When properly installed, SPF can lead to savings of up to 40-50% on heating and cooling costs, while also aiding the environment by reducing the usage of fossil fuels and other non-renewable energy sources. In a standard residential home, nearly 60% of heat loss is related to moisture in the air, – luckily, spray polyurethane foam is able to form an effective air and vapor barrier that will not absorb water and prevent condensation. This makes SPF the most complete and efficient insulation solution available on the market, suitable for numerous applications.

Their driver is unprofessional. I have everything recorded on my dash cam On Markham road in Scarborough (5:30pm 19/07/2022) Driver turned right on a red light and put him self in front of a semi truck. I hope the company can look at the footage and see what his driver did or can request the footage from me and I will be more than happy to provide him.

If I could give this company 6 stars I would. Courtney and her crew were amazing and very professional. We were blowing insulation into a large akward attic and she spent considerable time on preparing the site then took pictures of her work and made sure we approved before blowing in. She took great care when bringing in the bulky equipment and made sure everything was protected. After the difficult blow in more pics to get our approval.. then totally cleaned up as if they had never been there. Totally impressed. Give this girl a raise!
