The correct installation of polythene DPM, rigid insulation and separating layers are highly important not just for the overall integrity of the screed system but for the quality of the entire flooring. Unitherm® is made from Unipoly®, a light-weight moulded polystyrene material with exceptional thermal insulation properties. INSTA-PANELS ® are designed to be used as affordable and durable slab insulation and have all the benefits of regular sprayed-on polyurethane foam but in a clean and portable solution.. Common uses for INSTA-PANELS ® are:. 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 … To insulate a concrete slab, you will need to apply an insulation barrier. Many builders bevel the top of the vertical insulation so that none of the rigid foam is visible after the concrete slab is placed. The side-by-side insulation comparison highlighted previously found the EPS retained 94% of its specified R-value, while the XPS lost nearly half of its insulating capability over the 15 years the materials were on the foundation. While you can apply insulation over the concrete slab, that requires adding wood subflooring and other components that add to the cost and complexity of the project. Using an unnecessarily high-strength insulation, you end up paying for something you don’t really need. Existing Drywall. The U.S. Department of Energy (DOE) estimates insulating the exterior edge of slabs in slab-on-grade buildings can reduce winter heating bills from 10 to 20 percent. You can attach wood sleepers to the floor, fill the gaps with rigid-foam insulation, and then apply your finish flooring. 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. Installation of Unitherm® perimeter insulation is the simplest, most effective way to improve the thermal performance of the concrete slab. A careful evaluation of these materials' performance attributes against the project's needs … Yet, expanded polystyrene (EPS) performs as well or better than XPS, and at a substantially lower cost. There will be a damp-proof membrane under the insulation and possibly a second membrane on top, depending on the type of screed. Spray foam for sure has uses where it is the best choice by a long shot, but under a slab is not the place. The most common insulation materials for use under a concrete slab are extruded polystyrene (XPS) and expanded polystyrene (EPS). In this scenario, a rigid foam insulation is usual, and as you’d want the same U value in the roof, we need the same thickness of insulation (180mm). As such, it is not uncommon for under slab insulation to be over-designed by a factor of 10 or more. Concrete Slab Insulation. INSTA-PANELS ® are insulated R-11 foam panels made of rigid polyurethane foam, covered in steel or fiberglass on both sides. DuroFoam is the solution to your insulation needs. Underslab expanded polystyrene pricing is based on sheet quantity and thickness. In addition to under slab insulation, slab edge insulation helps prevent internal temperatures being varied because of exposed sides. Moisture resitance and stable R-value protects and insulates your concrete slab for a superior energy saving solution. Confirm with your engineer what strength is needed. Whether selecting EPS or XPS insulation, to ensure performance, confirm that the product was manufactured to meet the requirements of ASTM C578, Standard Specification for Rigid, Cellular Polystyrene Thermal Insulation. x 4 ft. x 8 ft. R-1.93 Insulating Sheathing (136) ... rigid foam insulation insulation foam boards foam insulation board In case your home is laid directly onto the ground, then added insulation will only prevent heat loss and the cold coming from the … Slab edge insulation protects the sides of concrete slabs. As insulation becomes increasingly common on foundations and under slabs, understanding the performance and cost factors of the different materials is important for successful bids and profitability. Unitherm sheets are available in 4 standard thicknesses, measuring at 2500mm x 1200mm, or can be custom made to suit your requirements.
