Superior’s low lying, flat geography means harbor wind reaches homes throughout East End and Billings Park with little to block it, and that exposure punishes underinsulated walls fast. The city’s early twentieth century housing stock, built during its shipping and rail boom, often carries original insulation, or none at all, in wall cavities never designed for today’s energy demands. Superior’s proximity to the water table also means insulation must be installed with moisture performance in mind, not just thermal resistance, since dampness in an improperly insulated wall leads to bigger problems than a cold room. Perrault Construction delivers insulation upgrades for Superior homes that account for both harbor wind exposure and this city’s specific moisture conditions.
Superior attics lose heat quickly under direct harbor wind exposure. We install attic insulation rated for this open, low lying geography.
Many of Superior's historic homes have wall cavities with little to no insulation. We upgrade these spaces to eliminate drafts and reduce energy waste.
Pairing insulation with new siding or windows delivers a complete efficiency upgrade for Superior's older housing stock.
We install insulation with moisture performance in mind, addressing both temperature imbalance and the dampness common in Superior's low elevation homes.
We evaluate your Superior home's insulation performance and recommend upgrades suited to the city's harbor wind and groundwater conditions.
