"Tomorrow: air sealing an attic……."
Are there any special tricks or products that you use when the surface temperatures that you are air sealing are below freezing? I noticed that the specs for spray foams and caulking usually have a lower limit of 40 degrees or warmer. Sure you can warm spray foam up to 90 or 100 degrees for application but as soon as it touches the cold surface, would that cause a problem?
