Modern spray foam insulation products are low-VOC and safe when professionally installed and cured properly.
Open-cell spray foam is flexible and ideal for interior walls, while closed-cell spray foam is denser and offers higher moisture resistance.
Spray foam insulation requires minimal maintenance once installed, as it resists settling and retains its form.
Spray foam seals air leaks and creates a tighter building envelope, which can significantly reduce heating and cooling costs.
