What is korolite insulation?
Korolite® Expanded Polystyrene (EPS) is a high-performance, closed cell, rigid foam insulation material that uses air as main ingredient. Excellent durability, recycled content and low environmental impacts using air as insulator instead of CFC, HCFC, or HFC gases.
What is Geofoam fill?
Geofoam is expanded polystyrene (EPS) or extruded polystyrene (XPS) manufactured into large lightweight blocks. The primary function of geofoam is to provide a lightweight void fill below a highway, bridge approach, embankment or parking lot. EPS Geofoam minimizes settlement on underground utilities.
What is the main ingredient of EPS?
EPS is manufactured from styrene monomer; low levels of styrene occur naturally in many plants, fruit, vegetables, nuts and meat. EPS is a derivative of ethylene and benzene and is made using a polymerisation process which produces translucent spherical beads of polystyrene, about the size of sugar granules.
How strong is Geofoam?
Despite its light weight, geofoam is remarkably strong. It can be produced with strengths up to 2,678 pounds per square foot, and as long as the combined dead/live load does not exceed one percent strain, EPS geofoam will never creep or experience plastic yield.
How much does Geofoam cost?
Construction considerations Recent cost estimates of geofoam vary from $55 to $100 per cubic yard, depending on a project’s required physical properties.
Is EPS flammable?
EPS is flammable, as is the case with so many other building materials. However, this is only relevant if you assess EPS as an exposed insulating material.
Is EPS waterproof?
Expanded polystyrene is commonly called beadboard. While polyiso, XPS and EPS have some of the strongest waterproofing properties of all insulations, EPS is the weakest of the three and absorbs more water. EPS is also susceptible to crumbling on the edges.
Is Geofoam flammable?
Q: Is geofoam flammable? Fire Hazard : Regular EPS and XPS products are combustible and protecting against fire hazard is an important consideration. Geofoam has been used for insulation and light weight fill applications for over 25 years.
Is Geofoam expensive?
Recent cost estimates of geofoam vary from $55 to $100 per cubic yard, depending on a project’s required physical properties.
What is Geofoam made of?
What is it made from? EPS Geofoam is made from a material called polystyrene polymer. This polystyrene resin “bead” is delivered in large containers and fed into a hopper for manufacturing. It is essentially a thermoplastic that can be shaped and reshaped repeatedly.
At what temperature does EPS melt?
212° F
If EPS is exposed to temperatures above 212° F (100° C), it begins to soften, to contract and finally to melt. Whether or not these can be ignited by a flame or spark depends largely on the temperature, duration of exposure to heat and air flow around the material (the oxygen availability).
Why choose airairfoam for building envelope insulation?
Airfoam delivers many building envelope insulation solutions at the highest R-value per dollar over other insulation products. With low environmental impacts and stable R-values, resilient EPS resists moisture and is ideal for continuous insulation applications that can all but eliminate the risk of condensation, rot and mold.
Why resilient airfoam insulation?
With low environmental impacts and stable R-values, resilient EPS resists moisture and is ideal for continuous insulation applications that can all but eliminate the risk of condensation, rot and mold. Most Airfoam products are available in various thicknesses & strengths to meet any project requirements – from underslab to the roof.
