Properly installed extruded polystyrene (XPS) foam can also improve a building’s energy efficiency by providing a complete layer of insulation on the wall. This reduces air movement through the wall that can rob energy. Insulation between studs does not necessarily offer complete insulation value because wood studs and other framing members are not insulated. This phenomenon is called thermal bridging and can dramatically decrease the thermal performance of the building.
Extruded polystyrene (XPS) foam can also have advantages due to its ability to assist with moisture management, resisting both water absorption and freeze/thaw cycles. When traditional insulation absorbs water, its thermal performance can be compromised over time.
EPS & XPS
Expanded Polystyrene, is a lightweight, rigid, plastic foam insulation material produced from solid beads of polystyrene (with a diameter of 0,2 to 0,3 mm). It can be seen in figure 2.1. Expansion is achieved by virtue of small amounts of pentane gas dissolved into the polystyrene base material during production. The gas expands under the action of heat, applied as steam, to form perfectly closed cells of EPS. These cells occupy up to 50 times the volume of the original polystyrene bead. The EPS beads are then moulded into appropriate forms suited to their application.
EPS (Expandable Polystyrene) is a polymer made of styrene containing pentane as a blowing agent. It is produced in the form of spherical beads. Due to its versatility EPS is the perfect raw material for various applications in construction, packaging and many special applications.
XPS (Extruded Polystyrene) begins as a solid granule of polystyrene resin. The plastic granules are fed into an extruder, where they are melted and mixed with critical additives to form a viscous fluid.
