Structural Insulated Panels onto the roof




Today started off as early as yesterday, with a 6:00 am call from the truck driver who was bringing the SIPs from the manufacturer in Montana. Looking at his Google Maps, he was concerned that his 60 foot plus truck and trailer couldn't negotiated the residential streets of Old Mountain View. After sufficient convincing however, he made it to site around 7:30, just when John arrived with the crane. We ran into a slight logistical challenge, since the truck with the SIPs had to park under the power lines on the street, but we solved it by unloading the panels with the bobcat forks and strong bodies.

Patrick had all of the sill plates installed, so putting on the SIPs themselves was relatively straightforward. Mic Carmichael of SIPBuilder took charge of the operation. He used OSB splines in all of the panel joints, as well as adhesive between the panels and the plates, followed by 10" long screws. I'd say that once the truck was unloaded, they had all panels up on the kitchen and bedroom volumes in about five hours. They're coming back tomorrow to screw off all panels and install the facia boards.

We also took advantage of the crane on site to set the two big steel beams that support the glass south wall of the living room. You can see this structure in the photos. Since the living room trusses didn't make the deadline, we're going to wait until next week to set the final roof panels, but we are going to pour the two remaining floors on Monday so we can start on the framing for the two bathrooms.

The last photo in the series is how the site looked at the end of the day Thursday. The panels remaining on the ground are for the living room roof and for the garage, which we'll build in a month or so. If anyone is interested in getting a little hands-on experience with rammed earth, drop me a line.

  2. Insulated Panels are generally recognized for great structural ethics, wetness along with heat control and higher insulating attributes.
