R-TECH® Rigid Foam Insulation
In addition, R-Tech has excellent dimensional stability, compressive strength and water resistance properties. R-Tech can contribute toward LEED® credits.
What is the R-value of R-tech insulation?
Q: What is the R-value of InsulFoam insulation? InsulFoam EPS has R-values that vary depending on temperature and the density of the product installed. For instance, our standard R-TECH, sold in home improvement stores, has an average R-value of about 3.9 per inch at 75°F.
Can R-tech insulation get wet?
properties will remain stable over its entire service life. There is no thermal drift, so the product is eligible for an Insulfoam 20-Year Thermal Performance Warranty. surface that is virtually impervious to moisture. manufactured with an inert additive that deters termites and carpenter ants.
What insulation should I use in my ceiling?
Depending on where you live and the part of your home you’re insulating (walls, crawlspace, attic, etc.), you’ll need a different R-Value. Typical recommendations for exterior walls are R-13 to R-23, while R-30, R-38 and R-49 are common for ceilings and attic spaces.
Can you put Styrofoam insulation in the ceiling?
Rigid foam insulation is one of several options for insulating a home. It is relatively inexpensive compared to other types and is fairly easy to install. Consider using this insulation in the basement, between floors, ceilings or even in the walls.
What is the R-value of 2 inch blue Styrofoam?
A wall utilizing STYROFOAM T-MASS Technology with a 2-inch exterior layer and a 4-inch interior layer of concrete along with a 2-inch layer of STYROFOAM extruded polystyrene insulation would result in a material R-value of approximately 11.33.
What is the R-value of 4 inch fiberglass insulation?
Batts. Fiberglass batts and rolls are ideal for placement between framing during construction in floors, walls, attics, and ceilings. They’re denser than blown-in insulation, offering an R-value of up to 4.3 per inch.
What is the R-value of 6 inch Styrofoam?
One common use of extruded polystyrene foam board is for foundation insulation panels. Polyiso (Polyisocyanurate). This is an even more dense and more expensive foam board insulation. It provides an R-value of 6 per inch of thickness and often comes foil-faced to help reflect radiant heat.
What is the R-value of 3 inches of spray foam?
Open cell spray foam insulation is R-3.6 to R-3.9 per inch. This R-Value is normal for open cell spray foam.
What rigid foam insulation is best?
Polyisocyanurate: Known as polyiso for short, polyisocyanurate foam has the highest R-value per inch (R-6.5 to R-6.8) of any rigid insulation.
What is the difference between pink and blue foam board?
Both are manufactured using the same process and contain similar chemical components. The two products also have the same insulating power. However, blue foam boards are manufactured by Dow Chemical Co. whereas the pink foam boards are manufactured by Owens Corning company.
Can R tech insulation be left exposed?
Exterior Application
Left uncovered these boards’ physical and insulative properties begin to weaken. First, their color fades, then the foam core suffers from powder chalking, and finally, the R-values deteriorate. To protect XPS foam boards from degradation, they must be covered within 60 days at the most.
Can you put fiberglass insulation over foam board?
If you can use the foam board and fiberglass – without compressing the fiberglass batts, then I say go for it. However, if you end up compressing the fiberglass then you will greatly lose the rated R-Value with an improper installation and almost certainly negate any possible benefits from the foam board.
How thick should my ceiling insulation be?
The higher the R-Value, the better the thermal performance of the insulation. The recommended level for most attics is to insulate to R-38 or about 10 to 14 inches, depending on insulation type.
Should ceiling insulation be faced?
Facing creates a moisture barrier through which moisture does not travel. Whether it’s made of paper or plastic, it always faces whichever space is typically warmest in winter.
Is R 13 insulation good?
R13 often does a good job of reducing cold temperatures in many of the country’s southern regions. Since many homes have 2×4 wall framing, particularly in their basements, R13 insulation is typically the primary choice for many property owners.
