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, a drywall bridge applies the drywall, and routs opening for any ceiling fixtures. The floor panel is rotated to the vertical for the installation of any electrical or fire protection systems. Once those systems are installed the floor panel is turned over and the Bridge applies the sub-flooring. Our standard sub-flooring is a Huber product called AdvanTech.
We frame our roofs in a post and beam method, so your attics will be free of any truss interference. There will be livable space up there, so we’ll be encouraging you to finish the attic. We can deliver it in an unfinished condition if that’s your preference. Each of the rafters are pre-drilled with the appropriate cut-outs for recessed lighting, sprinkler heads or other fixtures, whatever it happens to be.
Similar to the walls, we install drywall on the ceiling side of the roof and floor panels before insulation. The same insulation options are available. Once insulated, 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 roof and floors are now finished. They are shrink wrapped and placed on the pallet for transportation -- again stacked in the right order for installation and assembly on site.
