The home pictured above, being built at
The Glen at Cross Keys, has an exterior shell of SIS board (
structural insulated sheathing). This relatively new product from DOW offers structural support, insulation and water resistance.
In contrast, most other homes have an exterior shell of OSB (
oriented strand board) and house wrap, as pictured below.

If you are building a home, you should consider having your builder use an SIS board exterior to provide greater comfort in your home through a well insulated exterior.
You'll also find structural insulated sheathing at
Heritage Estates,
The Cottages at Stone Spring and
Founders Way!
