Rigid foam insulation is a versatile and durable product that can be used for various residential, commercial, and industrial applications. Many foam panels have high compressive strengths, are moisture resistant and provide long-term stability. EPS insulation and XPS insulation are two types of foam insulation.
EPS Foam Insulation
Foam insulation boards include; expanded polystyrene (EPS) foam insulation and extruded polystyrene (XPS) foam insulation. EPS insulation foam is a closed-cell structure that is made of expanded polystyrene beads which are joined together to create a cellular plastic board material. EPS insulation products have a number for benefits that make it suitable for both commercial and residential use;
•Excellent thermal insulation properties
•Maintains stable internal temperatures
•Reduces energy usage to increase energy bill savings
•Rigid foam structure allows for easy installation
•Can be cut to fit any space
XPS Foam Insulation
This is a closed cell extruded polystyrene insulation board, which means it is water resistant, and has high compressive strength. XPS insulation is versatile and durable which can be cut to any size and shape making useful in areas where other insulation types are not suitable. As XPS insulation is a closed cell structure it is unaffected by moisture and has the ability to retain its R-value in the presence of water. It has high R-ratings is also designed to maintain its R-value for the life of the building. XPS features and benefits include;
•High compressive strength
•High resistance to heat flow
•Low thermal conductivity
•Moisture and water resistant
•Lightweight and easy to handle
Open-Cell and Closed-Cell Foam Insulation
Foam that is classified as open-cell has added inflating agents that cause it to spring and compress easily, it also has a low density and is less durable. Closed-cell foams such as eps insulation and xps insulation are denser and solid in structure, which means it is more durable has able to withstand compression.
Installing concrete slab insulation can add extra comfort and warmth to your home and allow you to save on energy usage and bills. Up to 25% of a building’s heat loss, occurs as it escapes through uninsulated areas below ground such as foundations and concrete slabs. As insulation below-grade is often exposed to moist soil, it is necessary to choose insulation that is water and moisture resistant and able to dry quickly. As ground level temperatures fluctuate in most populated parts of Australia, slab insulation can sustain stable slab temperatures and reduces heat loss to the ground and minimize heat gain from the ground.
The Building Code of Australia (BCA) mandates slab-edge insulation if any form of heating is installed in the slab to ensure that heat is preserved for a longer period of time. For example, hydronic heating which uses solar heated water and distributes it throughout the building and foundation slab, and electric resistance heating which is the most common type of slab heating and is attached to the reinforcement before the slab is poured. Installing under-slab and slab-edge insulation allows you to moderate and maintain the temperature of the slab at and just below-ground level.
XPS insulation is suitable for a wide range of commercial and building applications, these include; under concrete slabs and can be installed around trenches, in between pods and around edge beams. Can also be applied to flat roofs like green roofs, wall and ceiling insulation, cool rooms and refrigeration, and cavity walls. XPS Insulation products at available at Pricewise Insulation include;
