Bob is back at the affordable housing project in Mashpee, Massachusetts, where he meets with developer Joe Valle, the chair of the Mashpee Zoning Board of Appeals, Mashpee's Assistant Town Planner, and a representative of the Mashpee Affordable Housing Committee to review how Act 40B benefited the community and the developer through creative zoning relief. At one home site, Bob learns about the detailed and finial-capped, maintenance-free vinyl picket fence from Perfection Fence that will sit in front of each home. The exterior of the house is being clad with cedar shakes on three sides and LP SmartSide engineered lap siding on the front fa?ade. This siding is made of medium-density oriented strand board (MDO) faced with a textured paint-based overlayer that gives a rough-textured, pre-primed, cedar-look appearance to the clapboards. SmartSide siding resists fungal growth and termites and carries a 30-year transferable warranty. Inside they are putting up the fabric to hold in the Blow-In-Blanket insulation in the wall and ceiling cavities. Pulling the fabric tight across the cavities holds the insulation in place and prevents settling. Once the untreated fiberglass insulation is blown in to a two-pound density, the exterior walls will have an R-value of 15.
