Product Details

Make sure your next new construction or residing job not only looks good, but also provides comfort, value and energy efficiency when you include Super TUFF-R polyisocyanurate insulation. These days, all homes need a solid, continuous, water resistant layer of insulation under the exterior finish. If you have insulation only between the studs, the wood framing can represent 25% of the surface area of a home's walls - and act as a conduit for energy loss. By adding Super TUFF-R insulation to your walls, you can enjoy the value-added benefits of energy savings by using this effective air barrier to cover cracks in old siding and around windows and doors. Adding Super TUFF-R to your home will have a temperature-stabilizing effect in the stud cavity, reducing the potential for moisture accumulating inside walls due to condensation.
  • Super TUFF-R R-3. 1/2 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 3.3
  • 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 also 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
  • 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
  • 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

Q:Can I use directly on the concrete basement walls?
by|Mar 30, 2022
3 Answers
Answer This Question

A:  Hi MaRe - Yes, you can adhere the insulation boards directly to concrete basement wall with adhesive. This product must be covered with a 15 minute thermal barrier (1/2-inch Type X gypsum board). We would recommend the use of furring strip mechanically fastened through the insulation into the concrete to use as a nail base for the drywall.

    A:  Yes

    by|Mar 31, 2022

      A:  Absolutely perfect for it. Not only is your basement a heat-sink(drawing out the heat from the house in the wintertime) but it can help prevent moisture buildup due to that transfer of hot to cold surface. It’s a moisture barrier and insulator. The mylar coating helps create a moisture barrier.      1st mix some thoro-seal or UGL paint and coat the basement walls with that to prevent hydraulic pressure of water from pushing in from outside. It is a powdered hydraulic cement paint that blocks water from pushing in from outside.      Then Install vertical furring stripes from floor to ceiling every 16”on center using concrete screws. Be sure to counter sink the screws.       Then Install the foam boards in between those furring strips. A snug fit will holdm.      Then Use aluminum 2” tape or tyvec moisture proof tape vertically from foam insulation panel-to furring strip-to foam insulation panel. This covers the wood furring strips to ensure a tight waterproof barrier between insulation panels.      Then install another furring strip on top the first furring strip to add thickness and an airspace gap between the sheetrock and the foam insulation. The gap is necessary for wires, outlet boxes, ductwork and plumbing. U have to space the gap to fit the things you plan on placing in/behind that particular wall. Hopefully this helps you.

        Q:I have a house trailer that is from 1965 with steel siding now. Can I install this inside over my paneling. Will moisture become trapped?

        Answer This Question

        A:  Hello Vermont homesteader - The aluminum foil facers on both side of the Super Tuff-R product will act as a Class I vapor retarder. If moisture came in from the outside, it will not be able to go through the foil facers. Also this product requires to be covered by a 15 minute thermal barrier i.e. minimum 1/2 drywall. The 1/2 inch Super Tuff-R would be the equivalent of putting up a 6 mil polyethylene, they both have similar perm ratings.

            I have a kitchen wall that is shared with the garage. Using the Loctite foam board adhesive, I cut pieces of the Super Tuff & was able to slide them behind the pipes/wires, and attach to the back of the drywall. The foam boards are easy to work with & cut. I used HVAC foil tape to seal the gaps between the foam pieces & will lay insulation on top of the foam board. I would buy Super Tuff again.

            Nice and Light
            In my closet, the back wall of that closet was against my Farmer's porch. The closet was always cold. So I ripped out the drywall to find no insulation at all. In doing it better than code, I first put 2 coats of Kilz, Red Rosin paper, then this foam insulation. It was very easy to cut and install. Lined up great, and provided a very noticeable difference in the temperature of the closet. When you don't have space for regular insulation I would recommend using this.

            This foam board was easy to cut and install. It has made a huge difference in my 16x16 wood framed workshop even though I still have the rear wall to finish. I am now able to keep the temperature at an average of 60 degrees using only one De Longhi oil filled radiator heater. Last winter, with no insulation at all, I was unable to work in the shop despite having a kerosene heater, a milk house heater and the radiator.
