Product Overview

  • Save money by lowering the cost of heating & cooling your home
  • Energy efficient alternative for non-insulating OSB or plywood
  • 1 in. x 4 ft. x 8 ft. R-6.5 Foam Insulation
Super TUFF-R polyisocyanurate insulation is helps improve the energy efficiency and comfort of homes. It will provide a solid, continuous, water resistant layer of insulation under the exterior finish. It also helps block costly energy loss that can occur between the studs of the wood framing. By covering cracks in old siding and around windows and doors, this insulation will greatly improve a home's energy efficiency.
  • Super TUFF-R R-6.5 1 in. x 4 ft. x 8 ft. foam insulation is Energy Star compliant and highly durable and moisture resistant; it installs easily over OSB or non-insulated sheathing and directly over wood studs
  • Super TUFF-R durable non-reflective faced insulation can reduce water and water vapor intrusion from the outside; it warms the wall cavity, thereby reducing the potential for dew point condensation forming in the walls – a key moisture defense
  • Meet or exceed federal guidelines for energy efficiency for year-round energy and money savings with an R-Value of 6.5
  • Super TUFF-R also acts as a component in a secondary drainage plane, allowing wind-driven rain (which can penetrate vinyl siding) to move quickly down the wall cavity and out the bottom of the wall – another valuable defense against moisture
  • Super TUFF-R can help protect resided homes against air infiltration through walls, which is a bigger problem than most people realize - on a windy day, air infiltration can cause significant heat loss in a home
  • Using Super TUFF-R in a residing application helps cover cracks in old siding and around windows and doors, covering the whole wall surface, not just the area between the studs, delivering air and water retarding properties for the walls of the home
  • Lightweight design installs easily over OSB or non-insulated sheathing and directly over wood studs - one facer is blue while the other is radiant barrier-quality reflective foil

Questions & Answers

Can this be used to insulate garage doors and left exposed?

Can this be used to insulate garage doors and left exposed?
Asked by: koby
Hi Koby, our Super TUFF-R™ insulation boards need to be covered by an approved thermal barrier, however our THERMAX™ products are able to be left exposed.

Can I use this on a boat freezer lid?

Asked by: Jessica
Hi, Jessica! DuPont™ Super Tuff-R™ Polyisocyanurate Foam Insulation could be used for this application; however, you would need to cover it with a thermal barrier. If you plan on leaving it exposed, you should consider using one of the DuPont™ Thermax™ Foam Insulation products instead.

Can i install this and soundproof insulation on top of it?

Asked by: C1
Short answer is yes. Long version is about sound isolation and effective spacing within wall structure, to reduce sound transfer thru wall. Check out internet resources for more info.

Specifications indicate this product is "fire block rated", what does this mean? If using on concrete block basement wall with 2x4 framing in front, is horizontal fire blocking needed every 10 FT? I still plan on placing vertical fire blocking to seal off fire spread to floor joists.
Asked by: Shane
Dear Shane: Good catch on the specifications! "Fire block" refers only to the ability to block air flow, and only applies (in this case) to residential buildings. In fact, all foam board products and flammable and emit toxic gas when they burn. Foam board and thick spray foam must be covered by an approved 'thermal barrier' in any living space, basement, garage or attic storage area. The standard is 1/2" drywall. Good idea to insulate your basement. Here are some tips: (1) Make sure there are no cracks and leaks in the walls. Fill and seal cracks with Sikaflex Model # 7116110, Home Depot Internet #300934565 Store SKU #652010 If moisture is coming through the wall, apply damp-proofing to the surface. Products like Drylok can provide an important layer of moisture protection. See: Drylok Model # 28615, Home Depot Internet #202610896 Store SKU #1000531519. This product will minimize diffusion from the soil through the foundation. (2) Use 2" thick Foamular XPS foam board. XPS does not absorb moisture; a 2" thick layer will provide R-10 insulation plus a strong vapor retarder. (3) Using foam board compatible glue, fasten sheets of foam board to your concrete walls. Apply a thick bead around the perimeter of each sheet, to create an air seal when it is pressed against the concrete wall. See: Loctite PL300 Model # 1421941, Home Depot Internet #202020476 Store SKU #780400. You can lean a 2x4 against each sheet to hold it in place while the glue sets, or pin them in place with a RamSet. After all of the sheets of foam board are installed, seal all of the joints and edges to block air leaks. DAP 230 works well for joints and small gaps; the 'Window and Door' version of Great Stuff foam is good for larger gaps. (4) Build your new 2x interior wall in front of the foam board. Use pressure treated (PT) lumber for the sole plate. If water leaks could occur and the floor may be damp, install a piece of Veranda cellular PVC trim on the floor first, to lift the sole plate off the concrete and keep if from rotting; leave small gaps every few feet for water to trickle through under the DriCore panels noted below. Use a RamSet to drive nails into the concrete, or drill holes for expansion bolts. We use bolts in areas with high stress, e.g. near doorways, stair landings and the ends of pony walls. See: RamSet Model # 00022, Home Depot Internet #100091715 Store SKU #107708. Be sure to wear ear and eye protection when you use a RamSet. (5) Insulate and seal the rim joist pockets: Install 2" thick pieces of Foamular 250 in the pocket at the end of each floor joist -- to insulate and seal the rim joist. Seal the edges with the 'Window and Door' version of Great Stuff foam to block air leaks. Then fill the rest of the end of each bay with rock wool. (6) Run your electric lines to receptacles and lights. Fire block (seal) the holes in the studs with 3M Fire Block sealant. See: 3M Model # FB 136, Home Depot Internet #100390499 Store SKU #191728 DO NOT use any type of spray foam, even if it says "Fire Block" on the label, e.g. Great Stuff. These spray foam are actually very flammable. Informed building inspectors can fail an inspection if they find spray foam used for fire blocking. (7) Fill the stud bays with rock wool. See: Owens Corning Model # UB-40-P3D-15--47--121, Home Depot Internet #304633821 Store SKU #1003061505 (8) If there is any possibility of a water leak into your basement, install DriCore panels on the floor first. They have a rubber surface on the bottom with channels that water can trickle through. Make sure, of course, that you have a drain with a dry well or sump pump for the water to escape to. Carefully seal all of the joints and edges of the DriCore panels to block air / moisture leaks. Then install 1" of Foamular on top of the DriCore, and seal the joints and edges. Cover the Foamular with 3/4" plywood as the subfloor / nailbase for your new flooring. Run the plywood 90 degrees from the direction of the foam board, with a 1/2" gap around the edge for expansion. Again, seal all of the joints and edges. See: DriCore Model # CDGNUS750024024, Home Depot Internet #202268752 Store SKU #361018. We installed DriCore at a recent project as a fail-safe, even though the basement was dry. Water leaked in unexpectedly through a window during a downpour, and DriCore saved the new floor. If you are certain that there is no possibility of a water leak into your basement, install 1" thick Foamular on the concrete floor -- and seal the joints and edges. Cover this with 3/4" plywood, running 90 degrees to the foam board panels. Leave a 1/2" gap around the edge to allow for expansion. Again, seal all of the joints and edges. (9) Also read up on fire blocking, which many people overlook. This is required at the top of basement walls, along the walls, at the top of stairs, etc. Do a Google search for "How to Firestop Your Basement" from ContractorKurt. Roxul rock wool is a good solution. You can stuff it into the gap at the top of the wall and into the end of floor joist bays. To seal holes created for pipes and wiring, use fire resistant caulk, e.g. 3M Model # CP-25WB+, Home Depot Internet #100166701 Store SKU #163096.. DO NOT use the "Fireblock" version of Great Stuff foam or similar spray foam products.. I hope this is helpful. Mark
