Hey everyone! I’ve been installing spray foam insulation in homes in the northern states and wanted to share some hard-learned lessons about cold climate applications.
Key points to discuss:
1. Temperature requirements for application (typically 40-90°F substrate temp)
2. Dealing with thermal bridging in rim joists
3. Open vs closed cell foam choices for vapor management
4. R-value requirements for cold climate zones
What has been your experience with SPF in cold climates? Any tips on substrate temp monitoring?
