The Floor and Roof Lines
We use an open-webbed joist for most of our floor applications; for special purposes we’ll use an I-joist or dimensional lumber. We like the open-webbed joist because if there is a retrofit issue you can easily fish any electrical or plumbing apparatus through the web. We have the ability to deliver a very stout floor and you should take advantage of that.
We slide the pre-cut joists into the specific locations controlled by a computer driven pin-table that ensures the precise location of each joist. The rim board is already routed to give us a complete connection with the joist. With the joists in-place, using a CNC bridge applies the sub-floor, and routs openings for any fixtures. We apply two layers of AdvanTech sub-flooring to our floor panels or in the case of roof panels a layer of Huber Zip roofing sheathing. The double layer of AdvanTech on our floor panels gives us unlimited access to the floor cavity during installation. The floor and roof panels are rotated to the vertical for the installation of any electrical, plumbing or fire protection systems followed by insulation according to your specifications.
Denim, rockwool, and fiberglass insulation options are available for the roof panels. Our preferred method is Cotton Armor, a dense denim batten that achieves R-50 in 11 inches. Once finished the roof and floors panels are shrink wrapped and placed on a horizontal pallet for transportation -- again stacked in the right order for installation and assembly on site.
