Flash and batt insulation brings together two of the most popular insulators: spray foam insulation and fiberglass batt insulation. This technique is used in wall cavities as follows:
- One inch of closed-cell spray foam insulation is applied.
- Once in place, a fiberglass batt is placed over the top of the foam.
Flash and batt provide the benefit of air sealing with spray foam insulation at a lower price point than full foam. This is a great option for a homeowner looking for air sealing who wants to be mindful of their construction budget.
Fiberglass is a very popular type of insulation due to its desirable price point and its ease of installation. Combining fiberglass with spray foam adds the air sealing benefits of spray foam with the price point of fiberglass and helps to remedy a lot of the shortcomings of fiberglass.
Flash and batt are also known as a hybrid insulation system, combining both fiberglass and spray foam. Flash and batt is a method of insulating standard stud walls by augmenting fiberglass batts with a thin layer of spray foam applied to the interior of a building sheathing.
Superior Rated Insulation
The addition of the spray foam gives the wall air sealing benefits and R-value in combination with the R-value of fiberglass insulation. An experienced contractor can easily install a flash and batt system by installing a layer of spray foam insulation and then filling the cavity with fiberglass insulation.
