Dicentes Residence, Kingfield, Maine.

When we air-sealed and insulated the attic, walls and basement of this home, we slashed the air-leakage by 60 percent and boosted R-values in all critical areas. (The Dicenteses were delighted they didn't have to switch on their furnace until mid November this year.) We also installed an automatic ventilation system to exhaust moisture and improve air-quality.
