Fairfax, Virginia – The Spray Polyurethane Foam Alliance is urging people to use spray foam to reduce asthma by making US homes more airtight.
It is estimated that 26 m Americans are affected by asthma, including more than 7 m children.
“Finding and implementing solutions for reducing asthma triggers should be a top priority for all,” said SPFA executive director Kurt Riesenberg. “Improving the built environment is one way to protect those who suffer from asthma.”
The American Lung Association links asthma directly to air quality and particle pollution. Triggers include airborne chemicals, pollen, smoke, dust and mould. Its “State of the Air 2016” report indicated that, even with recent improvements in air quality, nearly 23 m US residents live in areas where there are unhealthy levels of particle pollution year-round.
“SPFA wants to educate American consumers, homeowners, commercial property owners, businesses, builders and others on the importance of proper insulation and air sealing of the building enclosure as a means for lowering the number of asthma triggers able to permeate the inside of a home or building,” said SPFA technical director Rick Duncan.
The improved airtightness provided by spray foam allows for better control of indoor humidity, SPFA says, reducing the occurrence of mould. It also minimises the volume of exterior allergens and pollutants that can enter. Its ability to enhance energy efficiency could also contribute to a reduction in air pollution created by electricity generation.
“Spray polyurethane foam insulation and roofing are among the few products with such a positive effect on both ends of the spectrum – reduction in energy production and the maintenance of great indoor air quality,” Duncan said.
