Why Insulation Matters in Central Wisconsin

Stevens Point experiences distinct seasonal shifts, ranging from freezing sub-zero winters to humid summers, which places immense stress on your building’s envelope. Without adequate thermal barriers, your property becomes susceptible to heat loss, moisture intrusion, and the formation of ice dams that can damage your roof. Our comprehensive approach goes beyond simple coverage; we focus on creating an airtight seal that prevents air leakage—the leading cause of energy waste. By upgrading your insulation, you aren't just adjusting the temperature; you are investing in structural longevity, improved indoor air quality, and a quieter living environment.

Project Spotlight: Historic Home Retrofit in Stevens Point

We recently worked on a 1920s bungalow near the university district that was suffering from severe ice dams and drafty bedrooms. By removing the old, settled fiberglass and applying Closed-Cell Spray Foam to the roof deck and rim joists, we created a seamless air barrier. The result was an immediate 30% reduction in heating costs and the complete elimination of ice dam formation during the following winter.

Frequently Asked Questions About Insulation

How does spray foam compare to traditional fiberglass regarding R-value?

Spray foam, particularly closed-cell, offers a significantly higher R-value per inch compared to fiberglass. While fiberglass can sag or leave gaps over time, allowing air to bypass the insulation, spray foam expands to fill voids and adheres to building materials. This creates a continuous thermal and air barrier, which is often more effective at retaining heat in Stevens Point homes than R-value alone suggests.

Can spray foam insulation help with ice dams on my roof?

Yes, spray foam is one of the most effective ways to prevent ice dams. Ice dams occur when heat escapes into the attic, melts snow on the roof, and the water refreezes at the eaves. By applying spray foam to the roof deck, we stop the heat transfer at the source and air-seal the attic, keeping the roof surface cold and preventing the melt-freeze cycle.

Is it safe to stay in my home while spray foam is being installed?

Standard safety protocols require that residents and pets vacate the premises during the application and curing process of spray foam. This typically lasts for 24 hours depending on the product used. This ensures you are not exposed to off-gassing while the foam stabilizes. We provide clear timeframes and safety instructions before every project begins.

Will spray foam insulation rot my roof deck or wood framing?

This is a common misconception. When applied correctly, spray foam actually protects wood framing. Closed-cell foam acts as a vapor barrier that prevents warm, moist indoor air from reaching the cold roof deck, where condensation typically occurs. By stopping this moisture drive, spray foam reduces the risk of mold growth and rot compared to poorly ventilated fibrous insulation.

How long does spray foam insulation last?

Spray foam insulation is considered a lifetime product. Unlike cellulose which can settle, or fiberglass which can degrade and hold moisture, spray foam maintains its shape and R-value indefinitely. Once installed in your Stevens Point property, it does not require maintenance or topping off, making it a permanent solution for the life of the building.
