What Is Spray Foam Insulation?
Spray foam insulation is a two-component mixture made from isocyanate and polyol resin. When combined, these materials expand into a foam that hardens in place. There are two main types:
- Open-cell spray foam: Lightweight, more affordable, and effective at sound dampening.
- Closed-cell spray foam: Denser, moisture-resistant, and adds to structural strength.
Each type offers specific benefits depending on the application. Closed-cell spray foam is often preferred in Medicine Hat for exterior walls, basements, and metal roofs due to its ability to resist moisture and strengthen the building envelope.
Energy Efficiency and Climate Adaptability
In a city like Medicine Hat, where winters can be harsh and summers dry and warm, maintaining consistent indoor temperatures is essential. Spray foam insulation significantly reduces heat loss in winter and limits heat gain in summer. Its high R-value per inch allows for better thermal resistance compared to fibreglass or cellulose.
These are typical use cases where spray foam supports insulation performance and long-term reliability:
Wall cavities:
Wall cavities are filled to 4” with a levelled surface to 2 x 4 for easy drywall application. By spraying to this depth, the additional cost of a vapour barrier is not required, saving time and money. This is why professional spray foam insulation is your best choice.
Ceiling:
Two passes of the spray foam gun - 2 1/2” thick to achieve 5” of ceiling spray foam is equivalent to an R34 (+ / -) rating.

Structural Benefits
Spray foam insulation does more than regulate temperature—it can also add to a building's structural integrity. Closed-cell spray foam adheres directly to framing and sheathing, reinforcing walls and roofs. It can help a structure resist lateral forces such as wind or shifting soil, both of which can affect buildings in prairie regions like Medicine Hat.
By creating a seamless and rigid barrier, the foam helps to eliminate air gaps and drafts, reducing the risk of mould and mildew that may result from air or moisture infiltration. This is particularly beneficial in older homes where gaps in insulation can go unnoticed for years.
Addressing Common Misconceptions
Several myths circulate about spray foam insulation:
- Resale value concerns: Some homeowners believe that spray foam insulation can lower a property’s resale value. In reality, issues generally stem from poor workmanship or failure to meet local building codes, not from the insulation material itself. Proper installation and product selection prevent these problems.
- Off-gassing fears: A common misconception is that spray foam insulation releases harmful chemicals indefinitely. In fact, off-gassing only occurs during the curing phase, typically within the first 24 hours after installation. Once cured, it becomes inert and safe for indoor use when applied by trained professionals.
Our team at Peerless Building Products follows all required safety and ventilation protocols during and after application to ensure the material is safe for occupancy.

Project Management
Proper installation is key to maximizing the benefits of spray foam insulation. To ensure optimal results, it must be applied under conditions that meet the temperature and humidity requirements specified by the product manufacturer. This allows for proper expansion, adhesion, and curing.
Peerless Building Products employs certified installers with experience in both residential and commercial applications.
Long-term Durability
Once cured, spray foam insulation is highly resistant to deterioration. It does not sag, settle, or shift over time like traditional insulation materials. Many reports state that spray foam insulation can remain effective for the lifetime of the structure in which it’s installed. This makes spray foam insulation a practical investment for long-term property management in Medicine Hat.
