In comparison, how much does it cost to install spray foam?

In general, spray foam insulation is considered more costly than other conventional insulation products. However, the “cost-benefit” of the installation is well worthwhile. Spray foam insulation lasts a lifetime – with no need to replace and no need to top up.

With spray foam, the “pay-back” period ranges from 2 to 7 years. But the benefits are wide ranging:  home comfort and thermal R-Values are enhanced – energy wastage is reduced in summer and winter – and utility bills are dramatically reduced year round.
