What Insulation Typically Goes Under Concrete Slab? Building Codes For Rigid Insulation Are You Required to Use a Vapor Barrier Under Concrete Slab? How Much Does Rigid Insulation Cost? How To Insulate Concrete Floor Before Pouring Insulating Basement and Garage Floors With Rigid Foam Underslab insulation is any type of insulation that is used below a concrete slab on grade (a concrete floor directly on the ground). Common examples of under slab insulation include extruded polystyrene (XPS) and expanded polystyrene (EPS), but there are other lesser-known options on the market that we'll cover in this article.
Commercial BelowGrade & UnderSlab Insulation Insulfoam
ROCKWOOL concrete slab insulation is strong and durable, lasting for the lifetime of a structure 1 . As the insulation sits under the weight of the floor, its compressive strength makes it ideal for both domestic properties and commercial premises, where heavy product displays - for example - can weigh down on the floor 2 . Types Of Insulation For Under Concrete Slab The most common types of under slab or concrete insulation include rigid foam insulations, such as expanded polystyrene (EPS), extruded polystyrene (XPS) and radiant insulation, such as Prodex. Let's look at each type of insulation in more detail. Expanded Polystyrene Insulation requirements for slab-on-grade floors can be found in section R402.2.9 of the 2012 IECC and section N1102.2.9 of the 2012 IRC. Both codes state, "Slab-edge insulation is not required in jurisdictions designated by the building official as having a very heavy termite infestation." The insulation used under a slab needs to meet strength requirements, or else it can slowly collapse under the weight, destroying the foundation of the home. Compressive strength is measured in PSI and refers to how many pounds one square inch of the insulation can support.

Insulation extending away from the building shall be protected by pavement or by not less than 10 inches (254 mm) of soil. Insulating an existing concrete pad refers to adding an insulating layer on top of the pad and adding a new surface. This process will vary depending on the intended use of the space.

Under Slab Insulation with Radiant Heating Owens Corning Owens Corning® Enclosure Solutions
Insulating a slab prevents heat loss through conduction, which significantly offsets the energy costs of indoor climate control. Along with using energ y-efficient tax credits, this is one of the best ways to save money on energy bills. Lower Environmental Impact Insulation helps keep moisture from condensing on your concrete slab. Moisture problems inside a building can cause significant damage, such as mold and mildew under the flooring. Some under slab insulation products incorporate a built-in vapor barrier to help keep moisture out. Under Slab Insulation Options
Under Slab PSI Requirements. As a bare minimum, 16 psi is the lowest contractors will go on compressive strength of under slab insulation. It's best to use a factor of safety and settle with a slab insulation with a compressive strength in the 20-25 psi range. Options for Under Slab Insulation ENERGY STAR Single-Family New Homes, Version 3/3.1 (Rev. 11) Rater Field Checklist. Thermal Enclosure System. 3. Reduced Thermal Bridging. 3.2 For slabs on grade in CZ 4-8, 100% of slab edge insulated to ≥ R-5 at the depth specified by the 2009 IECC and aligned with the thermal boundary of the walls 15, 16.

Commercial BelowGrade & UnderSlab Insulation Insulfoam
EPS insulation in an under-slab application. Take the case of a warehouse with a 6-inch-thick, 2,500-psi concrete slab on 2 inches of EPS insulation with a rated stiffness of 360 psi for one inch. Forklifts to be used in the building impart 8,000 pounds of force at the wheel, which has a 6-inch by 10-inch tire footprint on the slab. EcoFoil Under Slab Insulation is a patented product specifically manufactured to withstand the pressure and corrosive nature of concrete and to provide the most reflectivity of any under-slab insulation on the market. It's a vapor barrier and works exceptionally well with in-floor radiant heat systems.
