building envelope

The building envelope, also called building enclosure, shell or perimeter, is simply the physical barrier between your home’s conditioned (heated or cooled) and unconditioned air. This consists of exterior walls, roof, sub floor, exterior doors and windows. A tightly-sealed building envelope is effective at keeping conditioned air inside your home, creating a comfortable living space with reduced energy output.

Hassler: California’s Building Envelope Consultant

Your home may be losing up to 15 percent of its cooled or heated air through leaky ducts, inefficient heating and cooling units, poor insulation or other easily solved problems. Hassler is your building envelope consultant. We can look at your whole house, from crawl space to attic, to find areas of wasted energy and create a high-performance strategy to increase your comfort and improve efficiency.

Our team is at the ready to help with all envelope improvements including air sealing, spray foam insulation, home recovery ventilators, and vapor barriers. Our trained technicians understand the conditions that impact California homes and can conduct home energy assessments, home energy ratings and whole house energy evaluations.
