The 8 Best Spray Foam Insulation Kits
This wiki has been updated 12 times since it was first published in October of 2018. Spray foam insulation is more effective that fiberglass and many other solid options, because it can get deep into cavities. Once inside those gaps, it expands to completely block all airflow. While these kits are designed to be easy to use, it is important that only experienced professionals do so as, if incorrectly applied, these chemicals can pose serious health hazards.

Spray foam has a number of properties that make it a versatile and indispensable building material. Not only does it insulate homes, thus reducing heating costs, but it also reduces noise transfer and helps to control moisture while improving the structural integrity. The types of foam listed in this ranking can be broken down into three basic types, closed-cell used for wall insulation, which traps gasses inside and provides a vapor barrier, closed-cell used for roofs, which is denser and therefore more expensive, and open-cell, which traps air inside and is used for gap filling, however, open-cell foam is not impervious to water and should not be used outside.
In this latest update, we added several kits to the ranking to cover all of the application requirements aforementioned. The Touch n' Seal 120 BF was added as a repair kit for roof structures and, as such, has high insulation properties and is resistant to thermal movement. The Touch n' Seal Two Component and the Dow Froth Pak 620 are both ideal for wall insulation, with the latter becoming tack-free almost instantly after application, and completely dry in just one minute. The Handi-Foam E84, the Dow Froth Pak 120, and the Fomo Products P40540 are all smaller kits that are better suited to filling gaps and crevices than full wall insulation, however, it should be noted that once opened most of these kits have a 30-day shelf life, therefore, pre-planning can prevent unnecessary wastage. For very small jobs, the Industrial Products Seal Spray may be a better option, as it comes in individual canisters, each covering approximately 25 board feet.
