• Double stud between panels are too much. But necessary for
• Leaves on flat roof
• Snow clogs on drainage
• Make roof bulletproof - not for only water
• Interest in dimensional control of foundations for SIP based ADU
• Overhangs are highly recommended. Get this on current version?
• Can build up a leaf condition on top of the roof.
• Difficult if just openings to drains.
• Labor skill is variable
• Metal roof is best -
• There is hardware that avoids birdsmouth
• Make the framing hard and waterproofing easy. Waterproofing as bulletproof as possible. Metal roof sounds great.
• There are PV panels that can clip right on to metal roof
• Solar panel frames that clip directly onto ridges of the roof.
• Single slope to the south. Clip them to metal.
• Minimum slope of metal roof - 3" per foot.
• 6'8" for occupiable space
• Short walls on third floor. 4 feet to 7 feet.
• Local work - best for structural engineer to work out bugs in realtime.
• Early-on design review - most good on the front end. Offer from David Mar.
• Ideally PDFs at end to mark up.
• Concept design - and feedback session.
• Build to last - not have someone rebuild in 10-15 years.
• PDFs that show panels and how they come together?
• Still need: footing plan. Insulation coming out a certain number of feet. Missing insulation coming out.
• 2x4 studs - OSB - Rigid - Finish.
• Cost of TJI - engineered joists? At 16' go to engineered joists?
• Throw in a block underneath double header. We have a 16" (walls) and 24" system (joists) wherever we don't have
• DIY SIPs? Passive house standards for cold climates? Superroof?
• Spider Crane - [1]
• SIP Lines - make SIPs
