Insulation & Envelope Guides

Your home's envelope, meaning its insulation, air sealing, roof and walls, decides how hard your HVAC system has to work. Austin attics get extremely hot in summer, so insulation levels and air leaks have a direct effect on comfort, humidity and energy use.

Good first reads are How Attic Insulation Affects Your Home, What R-Value Attic Insulation Do You Need in Austin? and Signs Your Home Needs Attic Insulation Upgrades. They cover how insulation works, how much you need and how to tell if yours falls short.

To see how blown-in insulation and air sealing are installed, our attic insulation page walks through the process.
