Spray insulation is an effective, efficient, and fast way to insulate a home. The liquid application goes on moist and malleable but then expands and hardens in place, filling every nook and cranny and providing excellent coverage. It is especially well suited for tight spaces that are difficult to reach with traditional batt insulation. It also works very well in new construction and pole barns. It can be sprayed over existing wood stud walls, although a vapor barrier is usually added after the fact for better moisture control.

Energy Savings

Because spray insulation creates such an airtight seal, it can significantly reduce the amount of time your heater and AC run throughout the year to keep your house comfortable. That cuts down on energy consumption and helps cut your energy bills.

While it is possible to install spray insulation on your own, a professional contractor can get the job done faster and neater than you can do yourself. It is also important to hire a contractor who is licensed and insured to ensure that the work meets all local building codes.

Toxic Ingredients

The chemicals used in spray insulation can be toxic, particularly the isocyanate from methylene diphenyl diisocyanate (MDI). This chemical produces a disturbing concoction of dioxins, furans, and carcinogens that are known to cause cancer, respiratory problems, and other health issues. The good news is that the new HFO blowing agents are less toxic and much more environmentally friendly.
