It’s a big day. Ranserve is insulating Emerald Hill. Framing is done. Plumbing rough-in is done. Drywall comes next.
Eleven years ago, when we built Sea Eagle with Hagy Custom Homes, we were one of the first homes in Austin insulated with BioBased spray foam.
Spray polyurethane foam (SPF) is a spray-applied plastic that can form a continuous insulation and air sealing barrier on walls, roofs, around corners, and on all contoured surfaces. It is made by mixing and reacting unique liquid components at the job site to create foam. The liquids react very quickly when mixed, expanding on contact to create foam that insulates, seals gaps, and can form moisture and vapor barriers. SPF insulation is known to resist heat transfer extremely well, and it offers a highly effective solution in reducing unwanted air infiltration through cracks, seams, and joints. Spray foam makes sense.
Sea Eagle is tight, comfortable, efficient. We believe our utility bills run about half that of nearby homes built about the same time that use conventional fiberglass batts.
So we planned from Day 1 to insulate with foam.
Before Energy Guard Foam Insulators pulled up to Emerald Hill this morning, Ron and Cris from Ranserve walked the house sealing up small penetrations with cans of spray foam. They also took the time to spray behind every electrical outlet in every exterior wall — “because the big guns the insulators use don’t always hit behind the electrical boxes,” said Ron.
To spray two liquids that instantly react to create foam, you have to have a surface to spray — so Ron and Cris installed drywall on the shared walls between the mudroom and garage — the first drywall screwed into Emerald Hill!
