Insulating on top of a slab is a fast way to warm up a slab-on-grade concrete floor. Continuous insulation is defined in 90.1 as “insulation that is continuous across all structural members without thermal bridges other than fasteners and service openings. Rigid foam insulations, such as expanded polystyrene (EPS), have been used successfully under concrete slabs for more than 40 years. Enhance energy efficiency and moisture resistance using Styrofoam™ Brand Rigid Foam insulation both under and over slab. One of my concerns was how this would effect my diaphragm but I can't think of a good reason why it couldn't be made to work. How to install rigid floor insulation on ground floor concrete substrates before screeding Posted on 19th October 2011 The following information is a guide to the installation of rigid insulation on ground floors to receive a screed. You can attach wood sleepers to the floor, fill the gaps with rigid-foam insulation, and then apply your finish flooring. Is one way better than the other from an architectural standpoint (str isn't in Revit yet :banghead:) One advantage to the novice, who has neither the equipment, the tools, nor experience to install foam insulation, is that rigid foam insulation can be installed very simply. OSB panels can be installed over concrete slab floors in both commercial and residential settings. This all-in-one product comes in tongue-and-groove panels that snap together over the concrete. Their researchers found that XPS insulation installed below grade for 15 years had absorbed 67 percent or more moisture. Such insulation helps reduce heat loss to the ground in residences, cold storage units, warehouses and other commercial, institutional and industrial structures. Building foundation slab sill plate sealing rigid foam the path to zero net energy 2017 03 concrete slab insulation for home concrete slab insulation peritussprayfoam eps and xps rigid insulation. EPS is also the most inexpensive of the three types of rigid foam insulation, while also meeting the required building and energy codes. Products and Resources for Interior Basements. A slabless slab may sound far-fetched, but peeling back the layers, we can see that the assembly begins with a compacted base over undisturbed ground. Spray foam for sure has uses where it is the best choice by a long shot, but under a slab is not the place. A well-insulated concrete slab ensures that the thermal efficiency of the property is controlled and maintained. While you can apply insulation over the concrete slab, that requires adding wood subflooring and other components that … For installation on concrete foundations and under floor slabs, the rigid foam insulation you choose can make a difference of tens of thousands of dollars on a project. Benefits of foam insulation under concrete slab . For under-slab applications, the rigid foam insulation typically should be installed over a gravel base, with a poly vapor diffusion retarder between the gravel and insulation. Concrete Slab. When building a slab on grade, EPS rigid foam insulation is the most common choice of insulation, for performance and cost. A common design assumption leads to specification of rigid foam strengths that are many orders of magnitude higher than necessary, which can double the insulation … EPS is, by far, the most versatile of the three rigid insulation options. I wouldn’t go as far as saying you 'couldn't' use spray foam below a slab, but I’m not sure why you’d want to. Products for this Application. The panels can be installed directly onto the concrete slab, over sleepers which are installed onto the concrete slab or over rigid foam insulation. at each tire. When exterior foundation walls are insulated, it helps the concrete stay warm and uses thermal mass properties to help keep the basement warmer. If I use a wall I can use a wall sweep and it is easy but if I use a structural foundation I can't use a wall sweep and would have to use an in-place model. Additional insulation is applied along the edges of the slab, because that is a primary surface for heat loss. Specialty subfloor systems consist of rigid foam insulation sandwiched between a vapor barrier on the bottom and a sub-floor material like plywood or OSB on top. Kooltherm K3 Floorboard. Exceeding the ASTM C578, ‘Standard Specification for Rigid, Cellular Polystyrene Thermal Insulation’. Suitable Product for Concrete Slab on Ground Floor. Perimeter slab insulation should cover as much of the exposed concrete as allowed by code. Concrete Slab Insulation DBWEF48100 (48” x 100’) – 400 sq. FOAMULAR® 1000 High Compressive Strength Rigid Foam Insulation 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. Notice that the sheet polyethylene “vapor barrier” is located on the top of the rigid insulation between the rigid insulation and the bottom surface of the concrete – in direct contact with the concrete. Concrete Slab Insulation. A 4-inch-thick concrete slab was placed on top of the vapor barrier. Rigid foam insulations, such as expanded polystyrene (EPS), have been used successfully under concrete slabs for more than 40 years. In cold climates (climate zones 4 and higher), it’s important to install vertical insulation on the interior side of the stemwall all the way down to the footing. XPS and EPS rigid insulation is used under concrete slabs. It can be mounted directly over the concrete slab, and abut the FOAMULAR® wall insulation where it meets the floor. He wants to put rigid insulation on metal deck and then pour a slab over the insulation. . Kooltherm K3 Floorboard is a super high performance, fibre-free rigid thermoset closed cell phenolic insulation for solid concrete ground based floors. As the slab will only be able to dry upward, the slab should be allowed to dry before finishes are applied. ft. About the Product: The Reflectix® Concrete Slab Insulation is an innovative, easy-to-handle product that increases the energy efficiency of radiant floor and snow melt systems (under concrete). It can be applied on the roof, floor, and walls, and it’s most widely used in structural insulated panels and insulated concrete forms. Many builders bevel the top of the vertical insulation so that none of the rigid foam is visible after the concrete slab is placed. Such insulation helps reduce heat loss to the ground in residences, cold storage units, warehouses and other commercial, institutional and industrial structures. When slab insulation is provided, a sheet polyethylene vapor barrier should be located over the rigid insulation and in direct contact with the concrete slab. phamENG - You are correct, this would obviously not be a composite deck situation. With solutions ranging from our OPTIM-R vacuum insulation panels to our Kooltherm phenolic insulation boards to Therma PIR insulation boards, we can provide the best solution for solid floors, below the screed or below the concrete slab, including floors with underfloor heating. Ground floor – insulation above concrete slab. Photograph 2: Perimeter Slab Edge Insulation and Perimeter Slab Insulation—Two inches of rigid insulation is about the maximum practical thickness possible. Under-Concrete Slab Adding a continuous layer of insulation under the concrete slab foundation creates a thermal barrier between the ground and the heat-conductive concrete. Over concrete slab floors, FOAMULAR® rigid foam boards offer long-lasting thermal protection. Or, as demonstrated here, you can cover the slab with rigid-foam insulation, add two layers of plywood, and then add the finish flooring. There are two ways to handle insulating concrete floors. Slab on grade Unlike its fluffier and flexible counterparts, foam insulation is rigid and needs to be installed correctly so that no gaps exist. In the case of a house in central Missouri, it is also a way to eliminate the concrete slab from the equation. If the vapor barrier had been placed over the gravel, below the insulation, we could have had a major issue on our hands with water retained in the foam insulation layer.
