Fasten, Faster: Baseboards and Electrical Boxes

by NUDURA Blogger | Jan 02, 2017

As a company built on high-quality service and responsiveness, we pride ourselves on answering builders’ questions before they even arise. However, we understand that each ICF construction job is unique and the design intent will vary from project to project.

How to fasten the baseboard in a NUDURA house is one of the most frequently asked questions we receive from builders. The short answer is, the best way is to rip a plywood strip 2 to 2 ½ inches wide and screw it in place to the webs along all the walls. Next, fasten these strips at every fourth web. At this point, you will be able to set drywall on top of it.

Cut the top sheets to the appropriate height and – bang! – you have full wood fastening for nails along the complete wall surface. The plywood is also guaranteed to be covered by the baseboard.

A different type of fastening question – this one concerning electrical boxes – is another that deserves a quick mention. Our 2 5/8 inch form panel thickness is deep enough to accommodate almost every standard depth electrical box, including a typical 1104 type box. During the pre-pour phase of the installation process, simply gluing a square of foam on the inside of the form to accommodate deeper boxes.

    What size and how should the boards for the garage doors be attached to the icf?

    Should we use 2x4 and attach them to the webs (each column is about 15" wide between garage doors). Or

    Attach 2x12 to reach both webs at the same time? Or

    Attach 2x4s or 2x12 to the icf with redheads or tapcon screws?

    Thank you

    Suppliers/installers are ultimately responsible for the performance of their product when accessorizing a home built with ICF.  Please refer to the manufacturers specifications that must be followed to ensure proper operation and warranty coverage of the installed product. Please contact for additional assistance to address this concern.

    While building the bay window, our contractor removed all foam and attachments to place a nailer to wall under the opening.  I believe this to be a waste of time and money.  Maybe you can elaborate on the situation.  Contractor believed that the attachment points were to weak to hold a cantilever wall below the windows as 3 window 30x48 European windows est. 80lb ea. to combine to a bow opening.  I suppose there is some shear but with upper support I don't see that being an issue.  If nothing else carve the foam off the attachment points so weight could not crush the small amount of foam, and to have a hard point, so not to sag with time.  I would like a rep to respond to this to confirm my argument or debunk it.  thanks.  

    A picture is worth a thousand words. For our technical experts trying to better visualize your description through a post, is prompting more questions about what is existing and without a cross section or photo of the actual installation to get a clearer picture of exactly how the foam was cut and removed and how the supporting blocking was installed, we really cannot adequately respond in a manner that your question deserves. The bottom line is- we would ask-is the installation as installed completed in a good and workmanlike manner as it has been installed? Is there any defect in the installation that is present? There are many ways to complete the detail. We are hesitant to render any opinion that might find fault with the builder, if in fact, he executed work in a manner that he felt was necessary to assure adequate structural support of the bay window over time, as ultimately, he remains responsible for final installation. Any other specific questions please message us at

    Our propane gas tech is installing a propane heater in our basement and has to cut through the wall to extend the vent pipe to the out for our direct vent heater. Any suggestions as to how and where on the wall he drills and cuts through foam and concrete?


    The NUDURA wall can be drilled at any location with the proper equipment, a core bit of the correct size is the most common tool. There are better locations than others to drill through, the ideal location is where the drill will not hit the reinforcing steel. Identify the reinforcing locations from the plans and specifications. Typically horizontal rebar is installed 1-1/2” – 3-1/2” from the top edge of the form, try not to drill in this spot. Typically vertical rebar is installed against a web/fastening strip, so if you stay between the 8” o.c. webs there is less chance of drilling into the rebar.

    I just want to know how much it would cost to build a 1200 sq/ft basement with your product ?

    basic 4 corners.

    Pricing depends on your location and the distributor in your area, as we don't sell our product direct. We have sales reps that can help answer your question, where are you located?
