Airplane Hangar Foam Insulation Application and Paint - Plus Apartment Redo! - VansAircraftBuilders.com Watch in HD on YouTube! Share on Facebook! I had foam insulation installed in my hangar. This foam conforms to the shape of the hangar interior walls as it dries, and almost looks like regular texture you would see in a home with sheetrock walls. It dries within minutes and is paintable in the same day. It also seals the entire hangar, preventing bugs from getting in. @Vansaircraftbuilders #Vansaircraft
