💡 What factors actually dictate long term performance in spray foam insulation
You are sick of watching utility bills climb, but true efficiency hinges on polymer structure and expansion ratios that decide how well your framing members hold indoor climate through brutal seasons.
- Polyurethane resin hardens against timber and concrete to seal convective leaks fast
- Dense closed cells bounce radiant heat inward while blocking summer humidity buildup
- Balanced material density locks in consistent R numbers so your blower motor burns less power overall
