concrete slab insulation

  • InfraStop® Under Concrete Slab Insulation

    Pouring a slab can be a considerable investment in time, material, and labor. When looking at insulation options, consumers can easily be confused as to what products to use and how effective they are.

    This post is to help you understand your options. Your first option is easy and that is to do nothing. Maybe you are not concerned with heat retention for your project. In that case, use the recommended poly vapor barrier. Lay down your rebar and pour the slab.

    However, if you want to retain heat and certainly if you are using radiant heat, than you will probably want to get some insulation down. The ground is an infinite heat sink and will continually pull heat from the inside downward. Insulating, or providing a thermal break, is the only option to slow this process.

    The most economical choice available is our InfraStop concrete insulation. Offered in a wide variety of roll sizes, the foil within the product acts to spread out the heat signature of heating coils. This results in a more consistent floor surface temperature. The multi-layered bubble design creates a thermal break to give you an R-1.1. Other advantages are rapid installation times compared to other products, the ability to install on uneven grade, and traditional vapor barriers are not required. The insulation itself is the vapor barrier.

    To gain more R-value you must move into the foam board insulation products. These products do have a higher R-value. They also have a much higher price per square foot unfortunately. Transportation and installation is also much slower as individual board sections must be laid down and the seams taped. A standard 400 square foot roll of our concrete slab insulation for example can be installed in less than a minute, compared to 12 sheets of foam board that can take upwards of an hour. For larger products we can manufacture roll sizes of 1,250 square feet to make installation even faster.

    Foam board is also prone to breaking and cracking on uneven grade. This can make your concrete pour susceptible to failure. This is not to say the foam board should be avoided but it does, as with all products, have its limitations. Understanding the pros and cons of the various products available and measuring these to your specific project will be able to better help you make your decisions on what products to use when insulating under concrete slabs.

  • Insulation for Concrete Slabs & Radiant Heat

    Do you want a thermal break between your poured slab and the ground below? Are you going to install a polyethylene sheet as a vapor barrier? Do you want a radon barrier? If you've answered yes to any of these questions Tempshield Concrete Slab Insulation may be right for you.

    It is an approved radon barrier which is now code in several locations in the United States. At 0.02 Perms, it is already an approved vapor barrier. At 60 lb./in puncture resistance it will hold up to all jobsite abuse and not tear like standard poly. Because of the 5/16" thick cellular construction, the material provides an effective thermal break. This results in an R-1.1.

    Per square foot, Tempshield Concrete Slab Insulation is the most affordable product on the market to provide a vapor barrier and pick up some R-Value. Because the insulation is rolled, in installs lightning fast compared to any board type insulation. Because it's strong and flexible it can be installed on jobs with uneven grade without breaking. It also is lightweight to handle and easy to install. Transportation is not an issue. We ship directly to you.

    Tempshield is non-toxic and non-carcinogenic as well as environmentally safe. The material consists of seven layers. The first white poly layer is bonded to the foil to protect from lime in the curing concrete. Each outer layer is bonded to a tough layer of polyethylene for strength. Two inner layers of insulating bubbles resist conductive heat flow while a center layer of polyethylene gives Tempshield high reliability and strength.

    For the concrete contractor or installer who is looking for a cost effective insulation that provides a vapor and radon barrier as well as thermal performance, you can buy Tempshield Concrete Slab Insulation here, at our Concrete Slabs and Radiant Heat Insulation site. There's no project too large for the InsulationStop.

  • Why Doesn't Bubble Foil Insulation Pop under Concrete?

    Why The Bubbles Don't Pop Under Concrete Why The Bubbles Don't Pop Under Concrete

    Won't the bubbles pop in the foil insulation?

    We heard this recently on a large concrete pour. This question comes up now and again. For the math inclined here's a brief sketch regarding concrete weights per square inch for a 6" slab. The bursting strength measured in pounds per square inch for foil insulation ranges from 60-160 psi.

  • Radiant Heat Floor Insulation: Wood Floors & Concrete Slabs

    So you've decided to install a radiant heat system in your floor. Congratulations. Your added effort plus added expense will ensure that you have the most comfortable, efficient heating system possible.

    Radiant Barrier Foil Insulation under Concrete Slab There is nothing new about heating homes with radiant heat. Actually it is the oldest, most durable mass produced heating system ever used. Almost all older homes, after the days of coal stoves ended, utilized boiler fed hot water to heat cast iron radiators. These closed systems are very clean and efficient and hold their heat in the radiators well after the boiler has turned off.

    Today's homes, unlike the homes of old, are built for affordability. Little attention is paid to overall quality and longevity. Forced air furnaces are now commonplace in most mass produced homes. Their ease of installation and low cost make them ideal for today's building style. There are several drawbacks to forced air systems. For one, forced air heat is very dry. Moving air accelerates the exchange of dust and other allergens. And, when the furnace turns off, your home immediately starts to lose heat. Also, most of the precious heat generated quickly rises and ends up at the ceiling where it is least desired.

    Radiant heated floors however utilize the same principles of older radiator systems. Their design is also a closed system. There is no forced or moving air to pull moisture from the home and spread dust and other allergens. With advances in materials these systems are affordable and are placed within the floor. The floor is warmed by the continuous movement of hot water. The entire floor is warmed eliminating any cold spots that are common in forced air systems. This heat is then radiated from the bottom, where it is most desired, upward through the building warming everything it contacts.

    The initial cost of a radiant heat system is more expensive than a forced air system. When measuring your return on investment it is important to allow your radiant heat system to operate as efficiently as possible.

    Radiant Barrier Foil Insulation in Wood Floor Using reflective foil insulation as a radiant barrier underneath your radiant heated floor is the single most effective insulation practice you can do to maximize your return on your purchase. Radiant barrier insulation blocks the transfer of radiant heat. When used underneath a wood floor or concrete slab this insulation reflects the heat back into the living space as opposed to being lost to the slab or under the floor.

    This allows the system to work less while providing the same level of heat. This equals energy savings. Adding a radiant barrier using reflective foil insulation is only a small percentage of the cost to install a radiant heat system. This one time step is an important component to maximizing your energy efficiency and should never be overlooked.

  • Concrete Barrier Foil: Under Slab Radiant Barrier Insulation

    If you are pouring concrete and intend to build a heated space on the slab, rFoil's Ultra CBF or Concrete Barrier Foil is for you.

    Ultra CBF has a patented design consisting of a bubble/foil/bubble detail or bubbles to the exterior and foil to the interior. This ensures the reflective barrier is never in contact with the concrete. The bubbles are industrial strength, specifically designed for use under concrete.

    Reflective foil insulation blocks the transfer of radiant heat, allowing for a warmer, drier basement that loses less energy. Foil insulation is impervious to water and moisture making it ideal in basement applications.

    Ultra Concrete Barrier rFoil is easy to install even on rough grade. The roll size is 48" x 125' or 500 square feet making transportation and installation much easier than competitive foam products.

    Ultra CBF is also an approved vapor and methane barrier, making the addition of standard vapor barrier unnecessary.
