A:  Hello Doug, If being used for crafts, oil-based and latex paints can be used with Foamular products. If being used in an interior construction application, painting the Foamular is not recommended as it will need to be covered by a 15 minute thermal barrier such as drywall. Thank you for your inquiry!

A:  Dear Doug: You can paint Foamular with standard acrylic primer and paint. That said, I hope you are aware that Foamular and similar foam board products are flammable and emit toxic gas when they burn. They must be covered by an approved 'thermal barrier' in any living space, garage, basement or attic storage area. The standard is 1/2" drywall . So for residential and commercial applications, foam board cannot be simply installed and painted. I hope this is helpful, Mark

A:  Dear Van12: Yes. If you are planning to glue sheets of Foamular to a metal roof, that is a good application. One important caveat: like all foam insulation products, Foamular is very flammable and must be covered by a 'thermal barrier' (e.g. 1/2" dry wall) in any occupied building, basement, storage area, barn, etc. Intumescent paint is also an option, if your building inspector approves. We recently used Foamular 250 to insulate a major remodel in Massachusetts. All of the stud bays on the exterior walls were filled with Foamular and air-selaed with Great Stuff. The exterior was also wrapped with 2" of Foamular to block thermal bridging and improve insulation performance. 1" x 3" strapping was added on top, to easily attach the new siding. A couple of photos are attached. A non-flammable alternative, Roxul ComfortBoard, is now carried by most Home Depots. Made from rock wool, it provides R4 insulation performance per inch -- almost as high as foam board. No thermal barrier is required.
