What is the compressive strength of XPS insulation?
FOAMULAR® XPS Insulation has compressive strengths of 15, 25, 40, 60 and 100 psi. The variety of products provides different strengths for use in walls, where there is almost no compressive load, or intermediate strength product for use with modest loads such as around foundations, or in low slope roofs.
What is compressive strength of insulation?
Compressive strength – the point at which the load causes the insulation to yield, before it reaches 10% relative deformation. Compressive stress – when the compressive strength is not reached, the point at which the load stress causes a 10% relative deformation of the insulation.
What is stronger 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.
What is the compressive strength of Foamular 250?
25 psi
* • Compressive strength of 25 psi. Effective resistance against moisture, mildew, corrosion and rot. Ease of handling and installation (lightweight, tough, rigid foam panels).
Does XPS compress?
What is the compression behaviour of XPS insulation? Among widely available insulation materials, extruded polystyrene (XPS) insulation offers one of the broadest range of compressive strengths and is one of the few products where manufacturers invest the time to test and declare compressive creep.
How good is XPS insulation?
Just like with EPS, energy efficiency is the primary feature of XPS insulation. Due to its physical properties, XPS has a higher r-value than EPS at 4.7 per inch. In the past, XPS manufacturers were able to claim r-values closer to 5.0 per inch.
What is the compressive strength of EPS foam?
between 10 – 60 psi
EPS has a compressive resistance between 10 – 60 psi for most construction applications. Within that range EPS can be produced to meet specific strength requirements.
What is XPS foam insulation?
What is XPS? Expanded Polystyrene, referred to as XPS, is a closed cell insulation product commonly used in remodeling and new construction applications. Due to the manufacturing process, XPS insulation is typically available only in standard dimension square or rectangular boards.
How thick is XPS insulation?
Product Data Table

| ¾” Thickness | 4.3 (0.76) |
| 1″ Thickness | 5.4 (0.95) |
| 1½” Thickness | 8.1 (1.43) |
Where is XPS insulation used?
XPS insulation can be used in interior walls, foundation walls, flat roofs, pitched roofs, floors and parking, cavity walls and sidings. SOPREMA manufacture and supply an extensive range of XPS insulation solutions for all of these applications, called EFYOS XPS.
What is steel compressive strength?
The compressive strength of steel is about 250 MPa while that of concrete ranges from 30MPa to 80 MPa. So the compressive strength of steel is about 5 times more than that of concrete.
How strong is steel in compression?
The compressive strength of ductile materials such as mild steel used for most structural purposes is around 250 MPa.
What is the difference between XPS and EPS?
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.
What is the compression of EPS?
The most important mechanical property of EPS insulation and building products is its resistance to compressive stresses, which increase as the density becomes higher. EPS has a compressive resistance between 10 – 60 psi for most construction applications.
How thick is XPS?
What is the compressive strength of polystyrene?
Compressive strengths† from 30 psi to 100 psi (210 kPa to 690 kPa) to meet the requirements of nearly every application. BASIC USE: COMPOSITION AND MATERIALS: A series of high strength extruded polystyrene rigid insulation boards used for civil engineering and other commercial applications.
Is XPS open or closed cell?
XPS is manufactured in a continuous extrusion process that produces a closed cell form of foam insulation.
What is XPS insulation made of?
Extruded polystyrene (XPS) foam is a rigid insulation that’s also formed with polystyrene polymer, but manufactured using an extrusion process, and is often manufactured with a distinctive color to identify product brand.
What is the compressive strength of insulation?
The compressive strength of insulation is the measure of how well it stands up to pressure before it begins to break. Both EPS and XPS come in compressive strength levels ranging between 10 and 60 psi. XPS also comes in 100 psi options.
Owens Corning® FOAMULAR® Half-Inch Extruded Polystyrene (XPS) Insulation is a closed cell, moisture-resistant rigid foam board well suited to meet the need for thin rigid foam insulation sheathing. R-Value Ranges: 3-3.2 Thickness Ranges: 0.5-0.5″
What is the compressive strength of XPS and EPs?
Although both XPS and EPS are available in compressive strengths of 15, 25, 40, and 60 psi, XPS also comes in 100 psi.
When do I need XPS insulation?
If the job requires 100 psi compressive strength, it needs XPS. Because of market dominance, XPS is more widely available from distributors and in the insulation marketplace as a whole.
