Where to Buy InSoFast

InSoFast panels are available for purchase here, on our website.

Next to the simplicity of installation, one of the best features of InSoFast panels is that we ship them (free!) directly to your site, anywhere in the contiguous United States. You may also special order them through your local lumber supplier, if prefered. They are not currently available at Lowe’s or Home Depot, which is actually a good thing because it means you’ll never have to suffer the circumstance pictured below:

The Struggle at Home Depot

Our free shipping is handled by a common carrier shipping company. You’ll get a tracking code and can even specify a time with the company that you’d prefer to have it delivered. We also offer a FedEx delivery service for even more hands-off convenience. We add $5/box to get panels delivered via FedEx.

InSoFast panels come in boxes that are extremely easy to carry. Our insulation actually fits through doorways! It can be easily maneuvered around corners and it weighs next to nothing.

You can learn more about all of our purchasing and shipping procedures by visiting our Order > Shipping and Purchasing policies page.

    do I have to seal my poured concrete walls prior to installing insofast?

  • Yes, but please note it is important to check with your local building code official to make sure the wood paneling meets your local requirements. InSoFast panels are classified as rigid foam plastic insulation. They fall into the same class as pink, blue and yellow insulation boards which are required by code to be covered by ½” drywall or any other approved 15-minute thermal barrier (IBC 2603.4).

    Here is more information on drywall and alternative finishes for interior walls.

    I live in Colorado where they require “floating walls” and the building inspectors say this product is allowed and

    “It must be installed per the manufacture’s installation instructions,
    and must still allow for slab movement, even at the outer walls.”

    How can it allow for movement when this basically is glued to the wall? Do you have any documents from folks in Colorado that have used your product? Thanks in advance!

    • The slab refers to the floor of your foundation. Here, the floating wall requirement ensures that if the soil expands or contracts beneath your home, the floor will be able to rise and fall independently of the walls. So it is okay to glue the panels to the walls because they are given space to float from the floor. For installation, we recommend using a temporary shim. Essentially, you would lay the shim (such as a 2×4 or something that meets the float space requirement) around the perimeter, install the panels and remove the shim once they have cured to walls and are ready to finish.

    Can the panels come in contact with a copper hot water heating pipe for several feet. I intend to box out the pipes after I get the panels up, but the clearance between the cement block wall is nominally 2 inches +/_ and so the panels will come in contact with the pipe in several spots.

    • The EPS body of InSoFast panels has a long-term temperature tolerance of 167° F and an intermittent tolerance of 180° F (see our Physical Properties page for more). If your hot water pipes are consistently near or above 167°, it would be best to surround them with a standard temperature-rated pipe insulation or spray foam to limit direct contact with the InSoFast panels. With either method you can carve out an area in the panels around the pipes to achieve the necessary clearance. This might be easier than re-running the pipes to push them a few more inches off the wall. Here is a Plumbing page which may offer some additional tips for your scenario.

    To insulate a 40 ‘ high cube walls and ceiling. What is appt cost

    • That is a difficult question to answer unless we know how many walls, floor, and ceilings -(minus) openings you actually plan to do. There are 12 different surfaces you can cover. Here is how to figure your needs. Measure your surfaces length x width add them all together. Then multiply the total surface square footage -(minus) window and door openings to get the total square footage. Once you have this number go to https://insofast.3dcartstores.com/ then see where your price per square foot is and multiply by the appropriate cost per square foot. The delivered price, for InSoFast, in the US lower 48 states will vary from $1.96 to $2.49 per square foot.

        Do you deliver to Big Island Hawaii

        • No we do not deliver directly to Big Island Hawaii. Our price includes delivery to a freight forwarder of your choice and then you are responsible arranging ocen transport. We have several projects in Hawaii and in the past the customer arranged transport from a port in Oakland, California.
