For best insulating of the entire home, should I apply Nansulate® to both interior and exterior?
Nansulate® can be used on either the exterior or interior of a home. We recommend coating one side of the wall, either interior or exterior, rather than both because in certain construction types condensation could occur between the layers. If you would like additional insulation benefit, you can add more coats. Longevity for an exterior application is approximately 5-10 years, due to exposure to the elements, and for an interior application it is 10+ years. Like all of our products, you can easily apply it just like a paint using a brush, roller or sprayer. The minimum recommended application consists of 3 separate coats with an hour of dry time in between. Lastly it must be applied where there is no chance of rain for 72 hours after applying the last coat.
