Installing high-density foam insulation beneath concrete floors keeps them warmer than they would be without the insulation during winter and decreases . Studies show that as much as 25% of energy loss from a structure can be attributed to a lack of insulation on below-grade foundations, cl spaces and under slabs
Nov 4, 2010 . Here's a video of insulating foam being put down and then the concrete slab being poured for our new office at 1500 W. College Avenue in Appleton, WI
Two-inch extruded polystyrene foam (XPS) is typically used as one-inch foam is too fragile to place under a slab. Expanded foam (EPS) is a less expensive option, and considered better for the environment, but you would need to use high-density Type II EPS for this application. Type II foam has a nominal density of about..
Nov 5, 2013 . As such, it is not uncommon for under slab insulation to be over-designed by a factor of 10 or more. Using an unnecessarily high-strength insulation, you end up paying for something you don't really need. Since EPS is lower cost per inch than XPS, and is available in a range of compressive strengths (from..
Owens Corning FOAMULAR 400, 600 and 1000 are high strength extruded polystyrene (XPS) insulation products designed for use in engineered applications requiring additional load-bearing capability such as under slab, concrete floors, foundations, roadways and rail beds, plaza and parking decks and cold storage..
HydroFoam is a lightweight high density EPS radiant heat insulation product that increases install speeds, easily cuts to any angle, offers R-10 value
Feb 16, 2012 . When exterior foundation walls are insulated, it helps the concrete stay warm and uses thermal mass properties to help keep the basement warmer. This present. . Which is more effective under the slab vapor retardant on the ground and then foam or visa versa? I would think the retardant would be on the..
.1 High density foam board insulation for [above grade,] [at grade,] below grade,] [______] applications. 1.2 RELATED . .2 [Section 03 30 00 - Cast-in-Place Concrete: Substrate foundation walls, grade beams, concrete slabs.] .3 [Section 04 22 00 . .6 [Section 32 13 00 - Concrete Paving: Under pavement insulation.]
Dec 23, 2014 . We put rigid foam under the footings. In some high-performance building circles, it has become common to place a layer of insulation under a slab on grade. This is . However, after extensive research it became clear there is a long history of using certain types of very high density expanded polystyrene..

FOAMULAR 250 Extruded Polystyrene (XPS) provides continuous insulation in insulated concrete sandwich panel walls, in masonry unit cavity walls, or when used with non-penetrating, surface mounted furring systems over masonry or concrete walls. FOAMULAR 250 retards the transmission of water vapor and moisture..
Jun 8, 2011 . Pink and blue rigid foam insulation boards are made from polystyrene resin that is melted and then forced through a die to form it into the desired shape. As insulators, pink . High-density blue foam products are designed to resist compression under heavy loads when they're used beneath concrete slabs
When installing a heated floor system, remember to allow sufficient EPS insulation under the slab. High-strength Benchmark Foam High-Density EPS is ideal for heated flooring system applications. Or choose Thermo-Snap (patented), our 4 X 4 in-floor insulation panels into which radiant tubes are easily snapped into..
NOFP insulation products includes reflective foil foam and under concrete radiant floor insulation products can be used in Wood Frame, Post Frame, and Metal . MicroFoil , MicroLT, MicroVent, RigidBoard, Igloo, and Premiere round out the line up of reflective foil foam insulation products that integrate high..
Exterior EPS sheathing can be used for above ground or below ground insulation to increase R-Factor in walls, or 2 to 3 inch thickness of one pound density foam .. The rigid, high R-Value composition of EPS foam adds an important element to a contractors ability to offer homeowners a way to seal the slab floor and the..
Aug 14, 2014 . Contractors are increasingly called upon to install rigid foam insulation under concrete slabs and on building foundations. 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. Now that high-performance building envelopes..
Jul 4, 2014 . Finally, some contractors in cold climates began installing a continuous horizontal layer of rigid foam insulation under their concrete slabs. The foam . With a layer of blotter sand, excess water can drain out of the fresh concrete, making it easier to place concrete with a high water/cement ratio. In contrast..
Dec 28, 2012 . Using rigid foam insulation around the perimeter of the slab to minimize heat loss seems like an obvious step, but whether to place insulation under the slab is another story. That decision may hinge . In radiant slabs, the slab temperature is much higher and it makes most sense to insulate because of that
ACH Foam Technologies' Foam-Control PLUS+ is an architectural insulation product line with high compressive strengths and R-values. . Foam-Control Radon Guard is a patent-pending, structural under-slab insulation and ventilation panel system that provides for radon gas removal, insulation, and a capillary..
Apr 15, 2012 . 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. Do not, and I repeat, do not locate the polyethylene under the insulation as it will keep the insulation wet
A common, simplifying assumption used for specifying polystyrene insulation under concrete slabs results in material costs that are significantly higher than necessary. Using a design equation based on a more rigorous analysis of the design conditions can help avoid over-engineering the insulation and save thousands of..
