Insulation EPS and XPS

There are two insulation types which are popular in a number of installations for the whole building envelope: EPS and XPS

With todayâs design-oriented goals of sustainability and strength efficiency, the proper usage of insulation is becoming more important than ever. There are various methods to insulate a building, and there are a large number of insulation assemblies in existence. This particular article focuses on two insulation types that are popular in a variety of installations for the whole establishing envelope: EPS and XPS.

Expanded polystyrene foam can be a closed-cell insulation thatâs manufactured by growing a polystyrene polymer; the appearance is a white foam plastic insulation materials typically. Extruded polystyrene foam is undoubtedly a rigid insulation thatâs shaped with polystyrene polymer also, but manufactured applying an extrusion process, and is manufactured with a distinctive color to identify product brand often.

Exposure to sun will deteriorate the product.

Solvents/solvent-structured materials cause irreversible damage.

Incompatible with specific thermoplastics, polystyrene insulations are recognized to draw plasticizers out of thermoplastic membranes, causing everlasting degradation.

Polystyrene is flammable, requiring proper placement in any assembly.

While EPS and XPS are two different products, they do have some similar attributes and are categorized as the same manufacturing normal: ASTM C578 Common Specification for Rigid, Cellular Polystyrene Thermal Insulation. This specific specification covers the different types and physical houses of cellular polystyrene intended for make use of as thermal insulation.

The different classifications relate with physical characteristics of each type â directly?most notably, the density, compressive level of resistance, and R-value. The number in densities and compressive strengths permits specific uses on different parts of a building.

Polystyrene insulation is manufactured in a variety of board sizes â?at the least 1-inch thick usually. Tapered units are as well manufactured for employ in roofing assemblies where in fact the insulation is used to generate slope for great drainage. One of the more prevalent uses in roofing is the ballasted single-ply roofing assembly, in which a roof membrane is positioned over the insulation and ballasted with rock, concrete pavers, or other material.

Polystyrene insulations can be used on extrusion systems asphalt built-up roofing systems; however, provisions must be designed to protect the insulation from temperature (i.e. awesome bitumen or torch) and solvent-based products. Furthermore, certain thermoplastic roof membranes need a separation layer between the level of insulation and the membrane.

XPS and eps will be resistant to moisture; however, XPS is more prevalent for below-grade roof and waterproofing systems where insulation is placed over the roof membrane. The IRMA concept is going to be utilized for insulating building walls likewise, where polystyrene insulation is positioned over a barrier membrane, with the siding or cladding program installed on the insulation layer.

Using XPS and EPS insulation in building construction offers great flexibility, compatibility, and thermal efficiency for use at all areas of a building envelope. Picking between your two will depend on particular work with; choosing the correct type is critical for proper insulation e
