Spray foam insulation is a great way to insulate your home and reduce energy costs. However, there are certain situations where it is not recommended to use this type of insulation. It is important to consider the location when using spray foam. Avoid using it near ceiling lights or heating appliances, as it can be flammable and could damage the light or wiring.
Additionally, it is not recommended to use spray foam on the roof deck, as it can prevent moisture from entering the attic space or accumulate in porous wood and insulation materials. Light boxes should also be taken into account when using spray foam. Lights are an ideal area for heat loss if installed on the underside of the roof, but some types of spray foam insulation can be dangerous around the top of light boxes. If you are unsure about which type of insulation to use, it is best to consult a professional. Finally, if you do decide to use spray foam insulation, make sure you have a solvent on hand. Foam solvent is a liquid designed to chemically dissolve aerosol foam before it hardens.
This will help ensure that your insulation is properly applied and will not cause any damage.
