Building a new home in Upstate South Carolina means dealing with intense summer heat that can easily turn a traditional attic into a blazing 150°F oven.
Instead of fighting that heat, our hybrid new construction approach completely transforms how the house handles thermodynamics. By spraying open-cell foam directly to the underside of the roof deck, we block radiant heat right at the source, bring the attic inside the conditioned building envelope, and keep that upper space sitting comfortably around 70 °F.
This is a complete game-changer for new builds—especially since HVAC units and ductwork are usually located up there. Instead of running equipment in a brutal environment, your HVAC system operates inside a stable, conditioned space, drastically boosting efficiency and longevity.
For the rest of the home, we keep the system both high-performance and cost-effective by installing R-19 batt insulation into the 2x6 exterior walls, paired with meticulous air-sealing to eliminate drafts. It is a smart, technical solution tailored specifically for our South Carolina climate.
