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 3 1/2 in. x 4 ft. x 8 ft. is ENERGY STAR compliant, highly durable and moisture resistant
  • Product 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 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

Rated 5.0 out of 5 by 7 reviewers.
Rated 5.0 out of 5.0 by 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. January 8, 2014
Rated 5.0 out of 5.0 by Polyisocyanurate not PolyStyrene! Just wanted to mention that this is Polyisocyanurate (Polyiso) not polystyrene (XPS). Polyisocyanurate has the highest R value per inch (3.3) vs. Expanded PolyStyrene (XPS) (2.5). Polyisocyanurate also does not use an ozone depleting blowing agent so it is better for the environment if you're so inclined. This also has an aluminum backer per Dow's site (search for Tuff-R) so it is a moisture barrier as well. Using this in the garage against the part that touches the house as it makes a better air seal than drywall and also is a thermal/moisture break against the drywall/stud interface. I will use Tyvek tape on the seams and caulk the top to provide a good air seal as well. Cheap compared to the thicker stuff although it's main benefit is the air/moisture blocking as opposed to the R value. April 4, 2014
Rated 5.0 out of 5.0 by insulation I have a board and batting building so I could not apply insulation to the outside of the building, so I applied it to the inside walls behind my Sheetrock. this is a great product and very economical way to insulate your house. It is also very easy to work with. February 7, 2010
Rated 5.0 out of 5.0 by Insulation This product has helped lower my energy bills. It also has helped keep the heat in the upstairs rooms in my old house. November 11, 2010
Rated 5.0 out of 5.0 by Easy insulation Used this before and it's an easy way to get decent insulation and sound deadening without the itch of fiberglass. Used the 2" thick version for another project with limited space for insulation but go a higher R value. January 27, 2015
Rated 5.0 out of 5.0 by Easy to install Polystyrene insulation is very easy to work with and install. I installed this in my basement for insulation and vapor barrier with Tyvek tape. November 30, 2011
