Tips to Applying Spray Foam Insulation in Winter

Spray foam insulation is an effective solution for keeping homes warm during the winter. This material serves as both insulation and an air barrier, effectively sealing wall, floor, and ceiling cavities to prevent the movement of air, creating a more comfortable and energy-efficient living space. In this blog post, we will discuss some valuable tips on how to apply spray foam insulation in cold weather, ensuring optimal results even when temperatures drop.

Winter-Ready Spray Foam Insulation Techniques that All Contractors Should Know

1. Prepping the Area

Before starting the application process, preparing the area properly is crucial. Make sure the surface is clean, dry, and free from dust, debris, and moisture. Cold temperatures will affect the curing time of spray foam, so ensuring ideal conditions will help achieve the best results. Using indirect heaters, warm the substrate up as much as possible. The warmer the substrate, the better the yield, the better the adhesion, and less chance of the foam shrinking back.

2. Adjusting the Spray Foam Machine

Both, the substrate and spray foam temperature, play a significant role in the insulation's effectiveness. Before starting, make sure the proportioner on the rig is set to the correct temperature according to the manufacturers recommendations for cold weather applications. This helps ensure the foam expands and cures correctly, providing optimal insulation properties.

3. Keep The Drums At The Correct Temperature

In extremely cold conditions, it is critical to keep the material drums at the correct temperature. In most cases the drums should be kept between 70-80 degrees. This can help prevent pump cavitation, off ratio foam, and inconsistent temperatures at the spray gun.

4. Monitoring Weather Conditions

Keep a close eye on the weather forecast before scheduling spray foam insulation jobs in cold weather. Avoid spraying on days with extreme cold or high humidity, as these conditions can affect the performance and curing of the foam. Aim for days with milder temperatures and lower humidity levels to ensure optimal results.

5. Adjusting the Spray Technique

In cold weather, it may be necessary to adjust the spray technique to achieve the desired results. Decrease the thickness of each pass when applying spray foam insulation, allowing for better adhesion and coverage. Be mindful of the spray pattern and pressure to ensure consistent application and avoid over-spraying or under-spraying.

Pro Tip for Spray Foam Rig Owners

Use the sun to your advantage whenever possible. Spray the side of the structure that is warmed by the sun first. it may be as much as 40 degrees warmer than the side that is not warmed by the sun.
