On this episode Wade will walk you through using closed cell spray foam under a concrete slab. Wade's company has been using this application for about 8 years and it has become almost their go-to application for insulating under a slab. What Wade likes about this application is:
- Just 2" of closed cell spray foam yields an R-14
- It's monolithic so its continuous with no joints or seams
- It is an effective moisture barrier
- Provides an excellent vapor retarder
- Is an excellent radon blocker
- Has a perm rating of less than 1
- Bonds exceptionally well to crushed stone - Наука та технологія
