Below-Grade Foundation Wall with FOAMULAR® 250 for impact and puncture resistance to protect the waterproofing membrane during backfilling and insulate the foundation/basement wall.
What is the R-value of Foamular 250?
(1) “R” per inch: 5.0 (at 75°F mean temperature). (2) Other sizes available on request.
Is Foamular 250 closed cell?
Owens Corning® FOAMULAR® 250 Extruded Polystyrene (XPS) insulation is a closed-cell, moisture-resistant rigid foam board well suited to meet the needs for a wide variety of building applications.
What is Foamular used for?
FOAMULAR® Insulation is used in many residential and commercial construction applications. Its uses range from below grade in foundations, to under concrete slabs, to all types of wall construction (steel and wood stud, masonry and concrete), and in commercial roofing systems.
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.
Which is better EPS or XPS?
In general, when comparing EPS and XPS board densities, the compressive strength of XPS is greater than that of EPS. For EPS to achieve the same compressive strength as XPS, the density of the foam would need to be increased, often resulting in a greater thickness of board being required.
Is Foamular a vapor barrier?
If FOAMULAR® XPS is used as sheathing on a wall, doesn’t that automatically create a “double vapor barrier”, potentially trapping moisture in the wall? The answer is, no.
What is the difference between extruded and expanded polystyrene insulation?
What is the Difference Between Expanded and Extruded Polystyrene? Expanded polystyrene or EPS is a thermoplastic foam material that we produce from solid beads of polystyrene whereas the extruded polystyrene or XPS is a foam material that we produce from solid polystyrene crystals.
What is the R-value of closed cell spray foam?
The R-value of closed-cell foam is R-6.5-7 per inch. Contractors often use it to insulate under slabs, ceilings, walls, and roofs. It performs better than other insulation types. It provides an excellent air barrier, resists moisture, and retards vapor.
What does polystyrene look like?
Polystyrene can be solid or foamed. General-purpose polystyrene is clear, hard, and brittle. It is an inexpensive resin per unit weight. It is a poor barrier to oxygen and water vapour and has a relatively low melting point.
Do you need a vapor barrier with rigid foam insulation?
Foam insulation usually does not require a vapor barrier. For some foam insulation types, such as closed-cell spray foam and foam board insulation, the insulation itself stops the movement of most water vapor.
Is XPS vapor permeable?
Therefore, 1 inch of XPS is considered to be vapor semi-permeable, while 2 inches is considered to be vapor semi-impermeable.
What insulation should I use in my basement ceiling?
Your best option is insulating your exposed foundation walls. Start with getting any moisture issues under control, then use water-resistant insulation like closed-cell spray foam or XPS foam board. Most homeowners opt for fiberglass, but fiberglass has the chance of trapping moisture.
Is Foamular toxic?
Acute Toxicity: Dusts may cause mechanical irritation to eyes and skin. Ingestion may cause transient irritation of throat, stomach and gastrointestinal tract. Inhalation may cause coughing, nose and throat irritation, and sneezing.
Is craft foam the same as Styrofoam?
The two most common brands of rigid, dimensional craft foam are Smoothfoam™ and Styrofoam™. Both brands are made from polystyrene, but the manufacturing process is different for making each of their sheets, balls and other shapes.
