Regarding insulation, the FHB House is definitely different from a code-built house. It is about 25% to 30% above the base requirement. We chose to hit R-20 under the slab, R-45 in the walls, and R-60 in the ceilings.
To insulate a house like this, you definitely have to pay attention to air-sealing. We used 15-mil poly on top of the insulation. We also used an air membrane to reduce air leakage through the wall.
Fine Homebuilding Recommended Products
Foam Gun
We like using a professional foam-dispensing gun as opposed to straw cans because it allows you to easily control bead size and reuse the can.
Loctite Foamboard Adhesive
When foam board installations require an adhesive, it’s important to use compatible products like this adhesive from Loctite.
Disposable Suit
This suit provides full body protection to help you stay clean from head to toe when installing insulation. We recommend wearing sweats underneath for additional coverage.
Respirator Mask
A full-face respirator prevents fog up and is more comfortable than constantly replacing particle makes that get fouled or sweaty and is ideal for the pro installer.
