Why Spray Foam Insulation in Wisconsin?

Wisconsin's harsh winters demand high-performance insulation. Focus on Energy offers cash-back rewards for spray foam installation. With a very cold climate, proper insulation is essential for maintaining comfortable indoor temperatures year-round.

In Wisconsin's very cold conditions, spray foam provides superior performance compared to traditional insulation materials. This can lead to substantial savings on heating and cooling costs throughout the year.

With average costs ranging from $3.00-$6.00 per square foot, spray foam insulation is a smart investment for Wisconsin homeowners.

Frequently Asked Questions

How much does spray foam insulation cost in this state?

Spray foam insulation typically costs $1.50-$3.75 per square foot, depending on the type (open-cell vs closed-cell) and project scope.

What R-value is required for insulation?

Current building codes require R-49 for attics and R-21 for walls in Climate Zone 6.

Should I choose open-cell or closed-cell spray foam?

In a very cold climate, closed-cell is recommended for its moisture barrier and higher R-value per inch.
