For many jobs, though, products with less compressive strength are more than sufficient and can reduce insulation costs. Install Unitherm® beneath the concrete slab to ensure optimal heating performance. Exceeding the ASTM C578, ‘Standard Specification for Rigid, Cellular Polystyrene Thermal Insulation’. Check out our full range of commercial insulation products here. Our Businesses In … This highly effective combination of materials offers high compressive strength and great thermal performance when used in below grade and under slab … Heat flows from hot to cold, and in the […] There are two ways to handle insulating concrete floors. Three important factors to consider when comparing these two insulations for any belowgrade or under-slab application are compressive strength, moisture retention, and insulating capability. Upload Any Drawings, Pictures or Information, Quality Assured Company by AS/NZS ISO 9001, For a detailed pricing take-off, please s. end through your information, drawings and requirements for an obligation free estimate. Rigid foam insulations, such as expanded polystyrene (EPS), have been used successfully under concrete slabs for more than 40 years. This is especially the case in colder climates. When extracted and tested after 15 years in service, the EPS had 4.8% moisture content by volume, compared to 18.9% for the XPS (a four-fold difference). Kooltherm K3 Floorboard is a super high performance, fibre-free rigid thermoset closed cell phenolic insulation for solid concrete ground based floors. Many designers mistakenly assume that loads placed on slabs transfer through to the underlying insulation and soil at a 45-degree angle instead of a more uniform distribution. Can withstand loads from large vehicles and equipment, Retains R-value even with moisture exposure, Easily shaped on site or supplied prefabricated, No long-term R-value loss or thermal drift. Underslab expanded polystyrene pricing is based on sheet quantity and thickness. 3 Results Insulation Location: Under Slab. Insulation with polymeric laminate facers keep water from entering the insulation and also provide an added barrier to water wicking or diffusing through foundations and slabs. In order of achieving this, you will need proper insulation installed. Unitherm® delivers the high compressive strength and efficiency required in residential slabs, preventing thermal loss through the ground. Moisture resitance and stable R-value protects and insulates your concrete slab for a superior energy saving solution. A number of studies show that EPS retains less moisture than XPS. Slabmate is an under slab insulation solution that is applied first and then the concrete is poured on top with reinforcement. Plywood. Ram Mayilvahanan is product marketing manager for Insulfoam, a U.S. manufacturer of engineered EPS insulation products. Such insulation helps reduce heat loss to the ground in residences, cold storage units, warehouses and other commercial, institutional and industrial structures. Up to one-quarter of a building’s energy loss is due to lack of insulation in below-grade areas, including the foundation and under slabs. Horizontal insulation placed less than 12 inches below the ground surface or that portion of horizontal insulation extending outward more than 24 inches from the foundation edge should be protected against damage by use of a concrete slab or asphalt paving on the ground surface directly above the insulation or by cementitious board, plywood rated for below-ground use, or other acceptable materials, approved … Slabmate will not breakdown over time, is made from high quality materials and no CFCs or ozone depleting properties are used in the material. One of the best ways to save money on rigid foam insulation installed under concrete slabs is to ensure the material is not over-engineered.

This encapsulates the reflective foil sheet preventing it from being exposed to the ground or the concrete, ensuring the life and performance of … That decision may hinge on whether the slab is heated, but there’s no agreement … With a large fleet of trucks and premium delivery service in Victoria, you ensure that schedules are met and concrete is poured on time. Let's unpack the issue in the context of ANSI/ASHRAE/IES Standard 90.1 - Energy Standard for Buildings Except Low-Rise Residential Buildings. A careful evaluation of these materials’ performance attributes against the project’s needs can dramatically shrink labor and material costs. In some high-performance building circles, it has become common to place a layer of insulation under a slab on grade. To insulate a concrete slab, you will need to apply an insulation barrier.
