How thick should EPS insulation be?
1. Insulation board covered by this specification shall conform to the nominal dimensions: Thickness: ¾ inches (19 mm) min to 12 inches (305 mm) max (specify thickness) Width: 24 inches (610 mm) Length: 48 inches (1219 mm) for PB Systems; 96 inches (2438 mm) for PM Systems 2.
What is the R-value of 2 EPS foam?
EPS insulation features an average r-value of 3.6 per inch. In addition to providing energy efficiency, EPS without film facers has a perm rating of up to 5.0.
Is Styrofoam and EPS the same?
The foam that you formerly knew as styrofoam is actually expanded polystyrene foam or EPS. This material is made from polystyrene, a plastic that’s often used to make clear products like food packaging or lab equipment.
Is EPS the same as XPS?
EPS (expanded) and XPS (extruded) are both closed-cell rigid insulation made from the same base polystyrene resins and manufactured differently, EPS is beads that are molded or cut into various sizes and shapes while XPS is extruded sheets.
Is Styrofoam XPS or EPS?
As we said, Styrofoam™ is a Dow trade, blue in color, and is an extruded polystyrene (XPS) foam made for thermal insulation, construction and craft applications. EPS is an expanded polystyrene available in various densities for insulation, construction and craft applications and so much more.
Does EPS foam shrink?
However, EPS also experiences post- molding shrinkage; it shrinks dimensionally from its molded size after processing. This means parts must be stored in warehouses until they are considered stable by the industry standard, DIN EN 1603. This often takes 11-18 weeks and is thus very timely and expensive.
Is pink foam board EPS?
Expanded Polystyrene Insulation Pink and blue foam boards are two types of extruded polystyrene insulation products. There are also expanded polystyrene insulation products which are far less costly than the pink and blue foam boards.
Does EPS need a vapor barrier?
A: No, although EPS has a low water vapor transmission rate, EPS is not a vapor barrier. Rather it “breathes”, and therefore does not require costly venting as do other insulation materials, which would otherwise trap moisture within walls and roof assemblies.
What is EPS foam?
Expanded polystyrene (EPS) is a lightweight cellular plastic material consisting of small hollow spherical balls that are expanded through a molding process in our factories to create a cost effective, highly efficient material used in hundreds of different applications.
Can EPS foam get wet?
EPS is resistant to water and moisture. This means that it does not absorb them and that its insulating performance is not compromised when in contact with these elements. Insulation boards made of expanded polystyrene can make a home healthier because they will not contribute to mildew formation.
What is the thickness of EPS foam?
96″x48″ and 48″x24″ Thicknesses 1″ to 32″ in one inch increments Can be cut to any thickness up to 32″ thick; Contact Usfor details. Features A lightweight foam, EPS is very popular for countless craft projects, and its easy to work with.
What are the benefits of EPS foam?
Features A lightweight foam, EPS is very popular for countless craft projects, and its easy to work with. EPS’s unique closed-cell structure allows almost total resistance from moisture & water vapor and will not rot or attract fungi or mildew. Also, EPS has a superior R-value, so it will insulate and keep heat or cool inside a particular room.
How are EPS foam blocks made?
A: EPS foam blocks are produced in a large mold, ranging in size from 3’ x 4’ x 16’ up to 4’ x 6’ x 24’ depending upon the facility. The blocks are then cut using a computerized hot wire machine to the desired sizes.
How much weight will an EPS block float?
EPS blocks float approximately 60 pounds of weight per cubic foot. EPS is used in most commercially available dock floats and is used unencapsulated in ponds and lakes throughout the country. A 4’ x 8’ x 12” thick block of EPS will float 960 pounds with half of the block out of the water.
