Open cell spray foam expands 100 times to fill all the cracks and crevices in the rim joist. With a total air seal that other insulation materials can’t hold a stick to, spray foam in the rim joist is one of the most cost-efficient ways for homeowners to take control of the comfort...
We chose this foam product for the installation shown above because we had room for plenty of insulation. Framing was using 2x6 wall studs and 12" I-joists for the roof and floor support system. Because this is an open-celled foam and vulnerable to water accumulation and leaks we felt tha...
It has become a popular alternative to fiberglass, mineral wool, and rigid foam board because it saves more energy than these traditional insulation materials in commercial, industrial, and residential buildings. Spray foam insulation, as opposed to conventional fiberglass insulation, can enhance indoor...
That stuff really adheres to foam board well. I think it’s crucial to seal up the joints as well as you can. Wrapping the additional fiberglass up into the floor joists is certainly a good idea. Reply LJ says: January 19, 2009 at 4:57 pm I recently framed the basement with 2×4...
XPS = Extruded Polystyrene Insulation XPS or extruded polystyrene insulating board is manufactured of closed-cell foam using an extrusion process. XPS has a greater compressive strength - that is, it's more dense or "stronger" than EPS.
The need for properly installed and correctly located insulation is not easily met using current construction practices. Rigid foam insulation board (sometimes referred to as RFB) is, in present common practice, supported by strips of lath (nailers) nailed to the rafters, joists, or beams between...

I’m going to use the XPS on basement walls, but i’m not sure what to do about the space above the concrete walls between the floor joists. Currently batt insulation is placed there. Do I need to do something special in this space? I don’t want to spend the time and money on ...
We speculate that there may be a further mold resistance when using a spray-in foam insulation product insofar as the foam forms a tight bond between the foam and the sprayed-on surface such as the sides of rafters or wall studs or floor joists and the underside of roof, wall, or floor...
