What would be a great adhesive to use on the sides? I need to break a piece into two in order to get it up into the attic to cover a whole house fan opening for the winter.
Asked by: Thomas
Dear Thomas: Use Loctite PL300 Foam Board Adhesive. See: Loctite Model # 1421941, Home Depot Internet #202020476 Store SKU #780400. Foamular XPS foam board is ideal for your house fan opening. Recent research showed that polyiso foam board R-value drops along with the temperature. XPS R-value increases slightly. So XPS is the best choice for cold winters. XPS also does not absorb water. I hope this is helpful. Mark

Can this be used underneath a radiant heat concrete slab that i am having poured in my garage? Floor will be 5” thick 3500psi

Asked by: Dan
Dear Dan: Yes, but use the other version, Foamular 250, which provides 25 PSI of compressive strength. Foamular 250 is ideal to insulate residential slabs and below grade walls. See: Foamular Model # 52DD, Home Depot Internet #202085962 Store SKU #307101 I hope this is helpful, Mark

Would this product be effective for use on knee walls? The knee walls already have batt insulation installed but I'm looking to stop a good amount of the hot (summer) and cold (winter) air that is coming through the soffit vent that runs the length of my bonus room over the garage.
Asked by: HotGAbonusroom
Dear HotGA: Yes, both Foamular and DOW polyisocyanurate foam board are ideal for this application. Dow's 'Super Tuff-R' polyiso will provide better performance in this temperature range than Foamular. See: Tuff-R Model # 99060464, Home Depot Internet #300528092 Store SKU #1002215973 Four key points for installation: (1) Roof venting: If this bonus room has soffit vents, was it originally a room or an attic? If there are open soffit vents, it sounds as though it was an attic when it was built. If the bonus room is now or going to be 'conditioned space' -- with interior heating and HVAC, you can block the soffit vents completely. If they are connected to a ridge vent at the peak of the roof (typically with plastic channels in the rafter bays), you can fill the rafter bays with rock wool before you install your foam board. Use Roxul ComfortBatt Model # RXCB551525, Home Depot Internet #205972546 Roxul will add R-4.1 per inch of thickness, which will be particularly important if you live in an area with hot summers or/and cold winters. (2) Install the foam board: Install the foam board on the surface of your rafters and knee wall studs. Screws work best, with a battery powered driver-drill. Leave a !/4" gap between the panels, which will make it easier to air seal them, as noted below. This will add R-10 to R-13 with 2" thick panels, break the 'thermal bridges' created by the (previously) exposed rafters and knee wall studs, and allow you to create an effective air seal. (3) Seal air leaks: Be sure to carefully seal all of the joints and edges of the foam board to block air and moisture leaks. If you leave 1/4" gaps, this is easy -- simply fill them with the 'Window and Door' version of Great Stuff spray foam. This version remains flexible after it cures, to prevent cracks as thing expand and contract. Seriously consider buying the 'Pro' foam gun -- which makes this MUCH easier and saves on foam. See: Pro Gun Model # 230409, Home Depot Internet #202892513 Store SKU #569349 If there are recessed lights in the ceiling, also make sure they are air tight -- to block air and moisture leaks. If these lights are older, you may have to install new sealed cans. (4) Cover the foam board: Foam board is flammable and emits toxic gas when it burns. It MUST be covered by an approved 'thermal barrier'. The standard is 1/2" drywall. I hope this is helpful, Mark

150 1 in. x 4 ft. x 8 ft. R-5 Scored Square Edge Insulating Sheathing is rated 4.5 out of 5 by 11.
Rated 3 out of 5 by from The Owens Corning 4x8 Formular 150 Insulating Sheathing makes a... The Owens Corning 4x8 Formular 150 Insulating Sheathing makes a better appearance, and was easier to install, than the roll insulation that was removed and replaced with the Sheathing. I won't know how well it insulates until the winter. While I find the Sheathing has a better appearance than the roll insulation, it was difficult to cut a straight clean edge as the Sheathing crumbled at the edge while being cut. If there were a tool that could accomplish a straight clean cut, then I would give the product a higher rating.
