Building Codes Then. Energy Efficiency Now.
Then: Insulation was treated as an afterthought. Building codes focused primarily on structural safety, and lower R-values were common. Air leakage and energy efficiency received far less attention.
Now: Modern building science recognizes insulation as a key component of an energy-efficient, durable building envelope. Today's energy codes require higher insulation performance, improved air sealing, and better overall thermal efficiency to help reduce energy costs and improve comfort.
As building codes continue to evolve, staying informed helps builders, contractors, and homeowners make smarter decisions for long-term performance.
