Why Spray Foam in Summer? | Best Time for Insulation | Aires.ca
Thinking about insulation? Discover why July and August are the best months for spray foam installation — faster results, fewer delays, and ideal curing conditions.

Timing Matters: Why July & August Are Ideal for Spray Foam
Spray foam insulation can technically be installed year-round — but that doesn’t mean all seasons are equal. At Aires, we recommend booking your spray foam projects during July and August, and here’s why:
1. Ideal Temperature for Curing
Spray foam is highly sensitive to temperature and humidity. Warmer conditions during summer months allow:
- Optimal chemical reaction and expansion
- Consistent curing with fewer variables
- Improved adhesion to surfaces like wood, concrete, or metal
Cold or damp conditions (common in fall or winter) can slow down the curing process or even compromise the foam’s performance.
2. Faster Project Turnaround
During summer:
- Site prep and cleanup go faster due to dry conditions
- Less time is lost to weather-related delays
- Cure times are quicker, allowing faster re-occupancy
This makes summer the most efficient time to insulate homes, barns, shops, or commercial buildings — especially when working on tight construction schedules.
3. Ready for Winter — Before It’s Too Late
Booking insulation during July and August ensures:
- Your home or building is sealed before cold hits
- You avoid last-minute emergencies or long wait times in the fall rush
- Energy bills stay low right from the first snowfall
Many builders and homeowners wait until September — and by then, crews are booked, weather gets cooler, and projects are more complex.
4. Easier Access & Scheduling
Summer means:
- Open construction sites for easy access
- Dry foundations, walls, and attics (critical for adhesion)
- More flexible scheduling before the fall backlog hits
Spray foam contractors tend to be busiest from late September through December — beating that rush guarantees availability and better rates.
5. Perfect for Agricultural Buildings
Farms operate on seasonal timelines. Summer is the prime time to insulate:
- Barns before fall livestock move-in
- Shops before winter maintenance starts
- Grain or feed storage before temperature swings affect quality
Spray foam locks in thermal stability — keeping livestock healthier and equipment protected when it matters most.
Plan Now, Save Later
Spray foam is a smart investment — but only if it’s done right, and at the right time. July and August offer the best conditions for performance, cost-efficiency, and convenience. Don’t wait for the rush. Lock in your spot before fall bookings fill up.
