Expert Answers to Green Bay Insulation Questions

How does spray foam insulation handle the extreme Green Bay winters?

Spray foam is superior for Wisconsin winters because it creates an airtight seal that prevents "convective looping." Unlike fiberglass, it stops the cold wind from penetrating your walls and prevents warm air from escaping, keeping your furnace from running constantly.

Can spray foam help prevent ice dams on my roof?

Yes. Ice dams are typically caused by heat leaking from your house into the attic, which melts snow on the roof. By applying spray foam directly to the underside of the roof deck, we keep the attic cool and prevent the freeze-thaw cycle that leads to damaging ice dams.

Is spray foam effective at reducing noise from nearby traffic?

Absolutely. Both open-cell and closed-cell spray foam have excellent sound-dampening properties. They seal the gaps where sound waves typically travel, significantly quieting noise from busy streets or neighbors.

Does your crawl space encapsulation prevent mold in Wisconsin’s humid summers?

Yes. By sealing the ground with a heavy vapor barrier and insulating the foundation walls, we eliminate the moisture source. This prevents the condensation that typically leads to mold growth and "musty" smells in Green Bay homes.

How long does the installation process usually take for a residential home?

Most residential projects, such as attic or crawl space upgrades, are completed in just one day. Larger commercial projects or full-house sprays may take longer, but we always aim to minimize disruption to your routine.

Is the spray foam used by Proseal environmentally friendly?

We use modern spray foam products that have low Global Warming Potential (GWP) and zero ozone-depletion formulas. By significantly reducing your energy consumption, spray foam is one of the greenest upgrades you can make for your property.
