The sustainability of a building really comes down to a snug, well-designed envelope. The walls, windows, doors, roof and floor are what prevent cold air from escaping the building in the summer and warm air from escaping the building in the winter. A good envelope has a high thermal resistance, or R-value. This equals sustained low energy usage and low energy bills.
Ecobatts are an environmentally friendly replacement to traditional fiberglass insulation. With an R-19 value, they are part of the Amazing Space wall system that, when fully assembled, will provide a snug R-30 building envelope.
The bats are made of sand and recycled bottle glass that form a glass mineral wool. The mottled brown color reflects their undyed, natural origins. Even the binder is a renewable, bio-based material that is petroleum and formaldehyde-free.
On the interior of the walls, plastic is used before the sheet rock is installed to create a moisture barrier between the exterior wall and the interior of the building. The insulation is naturally mold-resistant and water doesn’t hurt it. The walls are designed to be water-proof, but anything can happen over time. Proactively designing a wall system with strong integrity against the elements is designing a building with a long life-span that is easy and economical to maintain.
