Why is this house blue?

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!
