FAQs
How does Wisconsin’s climate affect insulation material choices?
Wisconsin’s extreme temperature swings and freeze-thaw cycles require insulation that maintains R-value performance year-round. Materials must resist moisture absorption during humid summers and provide consistent thermal protection when temperatures drop below -20°F for extended periods.

How do I prevent ice dams when upgrading insulation?
Proper ice dam prevention requires combining adequate insulation levels with comprehensive air sealing and balanced attic ventilation. The insulation keeps heat inside your home while ventilation maintains cold attic temperatures, preventing snow melt and refreeze cycles that create damaging ice formations.
Can I combine different insulation brands in the same home?
Yes, you can use different brands for different applications, such as CertainTeed blown-in for attics and Owens Corning batts for walls. The key is ensuring proper installation techniques and achieving the required R-values for each area, regardless of which manufacturer’s products you choose.
What maintenance does insulation require in Wisconsin homes?
Quality insulation requires minimal maintenance, but annual attic inspections help identify settling, moisture issues, or rodent damage. Check for compressed areas after severe storms and ensure attic ventilation remains unblocked to maintain optimal performance throughout Wisconsin’s seasonal weather patterns.
