Ceiling Install

The day roof install days have come and gone. We’ve installed our roof / ceiling and we now have a dry house. The SIP panels we ordered were 24’x4′ and 13″ thick with EPS foam in the middle, 7/16 OSB on top and 5/8″ OSB on the bottom. The 5/8″ OSB on the bottom was ordered smooth / shiny side down with no markings on it to be the finished ceiling. The sheets of OSB are single sheets with no seams along the 24′ length. Meaning they are not 4×8 sheets they are 4×24′ sheets. The thicker stuff on the bottom is to make fire code. It takes approximately 18 minutes to burn through a 5/8 sheet of OSB. Which meets standard fire code. The panels are huge in size, but not very heavy at about 380# per panel / 3.44# per square foot.

In my head I was thinking they would come on a semi-truck with a 54 foot trailer. I spent some time with the excavator on the driveway making the driveway wider to accommodate the longer rig. When the panels showed up they were hauled behind a dodge pickup with a 40′ trailer. No problem at all getting up the driveway. Dad brought the forklift over for the weekend and we unloaded the panels pretty quickly. The drive made two loads and we had all of our panels. Then we waited a few days for all of the help to become available. Took us two days to get all of the panels on the roof.

Cody and Trenton showed up Saturday morning and helped me get some of the panels in the right order and put some splines on. Forklift was key to stack the panels in the right order and move them around. Not sure how we would have done without the forklift. I suggest one for all SIP installers. The spines add the load bearing member of the sip of the panel. They are foam encased TJI engineered joists. We sealing them in the groves of the panels with an adhesive sealer to make sure they were airtight. Additionally I placed 3m tape sealer on top of the roof membrane before we roofed over the top as an added sealant along the seams

Dad lifted each panel into place with the boom truck while Trenton and I were on the roof beating the panels together with sledge hammers. Me in the middle on the ladder and Trenton on the roof the concrete walls. The panels fit together tab into slot b style. Once we’d worked out the cadence of the install the panels went up fairly quickly.

Always some pictures

A few more up in the middle starting to get a picture of what it will look like

End of the first day – half of the panels are on the roof. Looks like half of a house!

What the finished ceiling will look like – love the look of the beam and the wood
