Spray foam Insulation Contractor is a high-performance insulator that creates an airtight seal, making it perfect for insulating homes and buildings. It helps keep houses warm in winter and cool in summer, so homeowners don’t have to crank up the HVAC system as often or rely on space heaters and ceiling fans. That results in lower energy bills and less environmental damage.
But the spray foam itself can contain toxic chemicals and is a health risk to workers who install it, especially in unventilated areas such as tiny homes, shipping container homes, or concrete basements. It requires professional installation, and occupants must vacate the house during the process. It also off-gasses large amounts of volatile organic compounds (VOCs) during the application and curing processes. Some of these chemicals are isocyanates, which can cause eye and gastrointestinal irritation, as well as respiratory irritation that can lead to chemical bronchitis.
Healthier Homes, Happier Lives: How Spray Foam Insulation Enhances Indoor Air Quality
While the health risks of spray foam are still debatable, many builders have embraced it because it can help them meet energy efficiency standards and earn green certifications. Fortunately, spray foam manufacturers have begun to address the high global warming potential (GWP) of their blowing agents, with some now using low-GWP alternatives.
The “A” side of a spray polyurethane product is typically made from a blend of isocyanates and polyols, and the “B” side contains a mix of catalysts, blowing agent, flame retardant, and surfactants. When the two sides are mixed together in a spray can, they create a foam that is environmentally safe, Class One fire rated, and doesn’t retain water.
