The value should be your guide when installing insulation and foam. But, it should not be the only method to measure insulation because heat loss can happen in several ways. The six methods you can apply to determine heat losses include the following:
Heat Loss Mechanisms To Prevent
- Air infiltration
- Moisture accumulation
- Air intrusion
Spray polyurethane foam is effective in preventing the six types of heat losses. The six heat transfer methods should form a mechanism for you to choose the best insulation. You can as well use Energy star map to choose the best insulation in the United States.
