The Use Of Spray Foam Insulation in Zero Net Energy Homes

With the increasing cost of energy bills, both homeowners and home builders are looking for ways to reduce energy consumption.  with the average energy bill for a home in the U.S. nearing $1200 per year, there is greater demand for more energy efficient homes.  The term “net Zero Homes” refers to homes that have a net zero energy bill each year, producing enough of their own energy via solar panels, wind turbines, and other sources to replace the use of traditional energy.

Net Zero homes use advanced designs and building systems that might include thicker, airtight walls, heavily insulated windows and spray polyurethane foam insulation.

A standard-built residence might lose as much as 40% of its energy from leaks and cracks in windows, doors, walls and the roof.  Spray foam insulation addresses these problems by creating perfect seals, leading to energy savings.  Foam insulation also improves air quality by keeping out pollutants, dust, and allergens.  With the goal of Net Zero homes being an offset to energy bills, spray polyurethane foam insulation can be a meaningful contributor to an integrated solution.

The use of spray foam insulation can also reduce the stress on a homes’ HVAC system, especially for homes in warmer climates where HVAC and air handling units are located in the attic.  Another benefit of spray foam is that it might allow for the designer of a smaller, less expensive HVAC unit, producing more savings for the homeowner.

Most homeowners will agree that reduced energy consumption(and lower energy bills) is a great benefit.  We believe that spray foam insulation can play an important part int he design of Net Zero Homes, or any home where lower energy bills are an important consideration.
