Weatherization work focuses on the “building envelope.”

A good way to understand the scope of home weatherization
is to focus on the building’s skin –what building scientists call the “building envelope.”

This structural assembly typically contains wood framing (studs, plates, rafters and sheathing) as well as insulation, water-resistant membranes and finished surfaces (roofing, siding, wallboard). Windows and exterior doors are also included in the building envelope.

Why is weatherization important? Because most houses have too little insulation and too many air leaks.

Research by the U.S. Dept. of Energy tells us that many households use twice as much energy (including electricity, natural gas, propane and fuel oil) as they should.

Much of this wasted energy is due to leaky and poorly insulated building envelopes that force HVAC systems to consume excess electricity and/or fuel. You can detect these building envelope problems by looking for any of the following 6 symptoms.

Call Comfenergy for affordable and expert weatherization improvements.

Weatherization problems occur because builders aren’t required to seal energy-wasting air leaks or install more than minimum levels of home insulation during construction. But this doesn’t mean you have to put up with uncomfortable rooms and high utility bills.

Comfenergy’s highly trained weatherization installers and technicians can transform an uncomfortable, energy-wasting house into a comfortable, energy-efficient “green” home.
