In theory, it's possible to apply Cold Cell spray foam at temperatures as low as 5 degrees Fahrenheit, but to ensure quality, we recommend that you follow the 40 degrees Fahrenheit guideline. While you can apply spray foam insulation in cold weather, the job gets a little more complicated. Contractors can make things easier by storing their equipment properly. There are specific closed-cell spray foam blends that work best in winter.
You should always store them at a temperature of 70 to 80 degrees Fahrenheit. Monitor the air temperature in your equipment to keep your supplies at the right temperature. In general, drum temperatures should keep the material between 70 and 80 degrees Fahrenheit, on average, to keep the product stable and ready for optimal use. The material manufacturer's SDS can provide more accurate guidance on the required temperatures.
As a building insulator, spray foam provides impressive thermal resistance and even noise barriers. Whether stored or in use, it should be kept between 70 and 80 degrees. It also generally adheres better when the substrate temperature is not lower than 60°F. While it is possible to install spray foam at cold temperatures, there are a few things to consider before you start applying it for cold climates.
The simple and quick answer to whether insulation foam can be sprayed in cold climates is yes, but it comes with some complications, especially when talking about closed-cell spray foam and metal structures. This is an excellent question because, like all chemicals, the reaction of mixing foam into aerosol will depend in part on the climate. If you have a metal outbuilding, call Chicago Green to discuss your condensation and temperature regulation issues and how spray foam can work for you. While cold weather isn't ideal for a successful application of spray foam, there's no need to close projects when it's cold.
To properly install spray foam insulation in the winter season, you can use a spray foam mixture for the winter. Aerosol foam heaters cover the entire spray foam cylinder and prevent heat from escaping, allowing you to continue operating your business during the cold winter months. While the temperature requirements of spray foam are generally warmer, experienced contractors know how to properly install it when temperatures are lower than ideal. As mentioned above, when the surface of the substrate is too cold, significant condensation will form when spray foam is applied and the insulation will not adhere properly.
Minimizing the distances between spray equipment and the application site will also reduce heat loss by reducing the number of hoses exposed to the elements. This extreme temperature reacts with cold surfaces and air temperature and can form condensation on the surface you're trying to insulate. Since the components of the aerosol foam and the substrate must be heated separately, spray foam insulation for cold climates often requires two heating solutions. Aerosol foam insulation during colder climates is a challenge, as it should ideally be in the warmer months of the year.
If temperatures are below this range, there is a greater chance of equipment breakdowns and a greater chance of foam breaking, shrinking and not adhering properly to substrates. As with many home improvement jobs, cold weather presents some challenges when applying spray foam insulation. Just as heating your home to 75 degrees will cost more than heating it to 65 degrees, spray foam will cost you a little more to apply during the colder winter months. Insulated blankets aren't the best drum heaters either, as they allow certain areas to stay cooler than others, without solving the problem of cold material.
