UAF Sustainable Village Week 11: spray foam, decking & Sheetrock

Week 11 was a productive one at the Sustainable Village. Workers continued to install EPS foam (2 layers of 4-inch sheets) in three of the homes with a REMOTE wall system. We also sprayed polyurethane foam around the rim joist to seal it up.

Each home has a large, south-facing deck on the second floor. We finished the decks with a spray-applied elastomeric coating, the same stuff used for truck-bed liners, a durable, weather-proof material that is less material-intensive than wood and requires no penetrations in the ceiling. We sprayed foam insulation underneath the deck in the first-floor ceiling to create a warm thermal break.

This week we started hanging Sheetrock in the homes where we had already finished plumbing and electric. The interior is starting to look livable! Now it’s time to select 16 lucky students who will make the Village home. If you’re interested, visit http://www.uaf.edu/sustainability/sustainable-village.

 

Spray Foaming the Foundations

Two of the homes will have insulated raft foundations. This allows the house to rest directly on the ground, keeping the floor warmer than if it were elevated on piles. A thick mat of spray foam is designed to prevent heat loss from affecting the frozen ground, and a cooling system was also installed in the gravel pad to chill the soils if needed.
