More and more builders are using an insulation material that offers dramatic solutions to building problems: closed-cell spray foam (CC-SPF).
CC-SPF has been around for a couple of decades, mostly in commercial roofing applications, but in recent years its use in residential wall-cavity insulation and as a problem solver has increased
Among the many problems solved by CC-SPF we find: ice-damming, rim-joist insulation, leaky windows, unvented attic conditioning, drafts, crawl space conditioning, moisture control, air-infiltration control, leaky windows, pipe freezes and waste chase insulation.
Ice-damming - caused by air leakage, repaired with CC-SPF as thermal barrier, air barrier and vapor retarder
Moisture control - CC-SPF helps control moisture because it is an air barrier, a water barrier and a vapor retarder. These properties help manage rain and ground water, which “are the most important factors in the design of construction of durable buildings and for the control of mold”

Moreover, in high rise buildings CC-SPF helps manage moisture by avoiding consensation on thermal bridges due to air leakage.
