Spray Foam in Cold Areas

While attic insulation rocks (especially for pole barns and commercial buildings with metal components), the material does have some issues when it comes to adherence to cold surfaces. The problem stems from the significant difference in temperature between the hot closed-cell spray foam and the cold surface it’s insulating. When these two materials meet, condensation forms, which can result in adhesion and moisture problems in the finished building.

Spray Foam Under Rafters: Benefits and Considerations

In order to minimize these problems, it’s important to maintain the proper temperatures of both the spray foam components and the substrate being insulated. This can be accomplished through a variety of methods, such as using heated trailers and insulated hoses during cold weather installation. Torpedo heaters are also a great option for raising building and substrate temperatures while the installer is in the process of spraying. A laser thermometer should also be used to monitor substrate temperatures during application, as well as a moisture meter to ensure surface conditions are dry prior to spraying.

Keeping your spray foam in the right temperature range can mean better coverage per gallon, faster project start times, and fewer hiccups during the cold-weather application process. IDI offers a number of drum heaters that keep your spray foam at the right temperature in storage, and insulated hoses can be added to these systems for even more consistent heating.
