West Haven, Connecticut - Spray foam equipment and material supplier Spray Foam Nation has contributed insulation to a Long Island house-building project which could produce the highest LEED score in the entire US. LEED stands for Leadership in Energy and Environmental Design. The Long Island project is pioneered by the Hamptons Green Alliance (HGA) which aims to promote green building and maintenance practices.
Spray Foam Nation blew SPF insulation (Foam Lok material from Lapolla) into the house to create an airtight and energy efficient environment, with the objective of helping to seal the building envelope.
SFN says when determining a home's energy efficiency, an important factor is the R-value of any insulation, which measure an insulation's ability to resist heat flow or thermal resistance. The higher the R-value, the more effective the insulation will be. Standard fibre-glass insulation is typically around 3.5 R-value per inch. The closed-cell foam used in this project is about 6.5 R-value per inch. This represents a significant improvement in energy efficiency.
The company said this project has a strong potential effect on the future of energy efficient homes. With a LEED rating of 108, the building aims to be the first Net Energy 0, carbon neutral and LEED platinum for home project on record.
