  Years. Ago I worked with a sip panel company…. And we used up to a. 8/24 foot panel .. it was. AWSOME … using the panels for the roof and walls … putting in a window or door just take out a chainsaw and put it wherever the customer wanted it.. customers would usually change their minds about where they wanted it after the walls were up as apposed to what was on the blueprint… plugging a space where they had originally planned was easy to install as well ….   Sound proofing and insulation quality was excellent compared to any other system….

  Great analysis and further makes the point that if you want to do anything construction related in the UK and have it turn out right, on time and on budget, then do it yourself!<br>Looks like you have an excellent integration of sketchup with the your excel costing sheet, would you do an upload explaining your workflow sometime?<br>I watch a lot of UK based construction related youtube and you content is top stuff and extremely useful !

  I built my tiny house on wheels with SIPs. I believe the cost was $3.8k for an 8.5&apos;x22&apos; x10&apos;h shell that i picked up and assembled myself. <br>This was pre covid but it worked well for me.

  Great videos, thanks. However I would like to point out that your timber-framed wall example that reaches a u-value of 0.10w/m2K &nbsp;adds up to an overall wall thickness of 427mm, not 328mm as stated. A similar wall thickness to the SIPS example and no reason why it should be that different in thickness anyway.

  Great video, I’ve been installing sip kits for a while and I’ve noticed a lot of people wanting to build out of sips are looking to make green homes, ultra modern homes , energy efficient and make them air tight etc

  I agree that for a small extension you are correct. &nbsp;<br>For a full house new build, perhaps SIPS make sense.<br>A lot comes down to how diligent your builder is. <br>SIPS definitely win on air tightness. &nbsp;I suspect a lot of framed buildings only get passed due to expanding foam to seal gaps, which is hardly a permanent solution.<br>Framed buildings often have poor cold bridges. &nbsp;Though a continuous sheet over the outside of the framing should sort this.<br>One thing most SIPS no longer have is a stud between panels, they use a strip of OSB slipped and glued into a slot behind the OSB. So no thermal bridge, and an excellent moisture seal. <br>Of course SIPS are still relatively new, who knows how long the essential glue bond will last?

  We have just built a SIPs home here in New Zealand. The panels came to 24%of the total cost. We built our own home and did 95%of the work ourselves. It took me 1800hours and running my wiring and pressure water plumbing we only used 2tradies. With a large deck the size of the house cost was just over 4000$per square meter. We live in a very cold climate in winter and with a small wood burner I&apos;m in a singlet and shorts inside all year round. Running services on the exterior panels is the &nbsp;only hassle with a cavity wall required.

  I don&apos;t recommend buying from the dictators but I bought SIP panels with 15mm OSB in 2019, total thickness was 15+190+15 (OSB+EPS+OSB) and I payed 105 USD per piece (1200x3000) so about 30 USD per square meter, then I payed a high price for the 20 feet shipping container but I got even more when I sold it in Sweden so I can&apos;t add that cost really, but I can add the 2000USD customs fee for handling import and 25% VAT (bought it as private customer so no VAT return.) &nbsp;But in total I payed close to 8000 USD for 145 square meter of outer wall with 190mm EPS insulation which I think is very price competitive. I also bought 150 sheets of grade B+ pine Plywood for 34 USD per piece and 54 pieces of 6m long 45x300 LVL Beams that are flawless for 60 USD per piece. So regarding how crazy the prices became in Sweden during Covid I saved a real big chunk by the China trades but I&apos;m not sure I would do it again.

  I’ve constructed a few small buildings but the two I use for comparison were a framed workshop using eased edged treated 3x2 and usb3 9mm sheets and 97mm SIP 8x4. I can say without any hesitation I’ll never touch SIPs again, when you build on your own as I do, never any help when you need it but that’s my choice working with SIP sheets once they are jointed and the edge timbers glued and screwed is back breaking they must be 40 plus kilos and very tough to move lift and position. With a framed building the most difficult job of the whole build in terms of lifting was the rubber roof covering which I lifted one ladder rung at a time to the top that was really hard, I knew I was in trouble when I went to collect the rubber sheet when it was brought out to the car with a fork lift truck, the bloke said have you got any body to help I never even try and lift those. But SIP panels are constant massive efforts each one you glue and screw in place or nail whatever. You can pay upto £100 a panel and the quality varies some are terrible and need every recess cleaning out to fit the timber inserts. You’re told it’s 50x 75mm I cut my timber before delivery big mistake as they are not that size. 47x72mm would be a better estimate, some sheets have a twist in them, some have a misplaced insulation so you end up having an hours work on each sheet cleaning out the excess glue, styrene insulation and poorly positioned sheets to enable your timber to fit. The joiners have thin OSB so you need to be very careful with the screws if you’re screwing, the material will strip out and the screws just spin, I had to countersink every hole on the joiners, this allowed the screw to pull up and tighten the cheeks as clamping would have been needing, a nightmare. Never again. I didn’t find a huge difference in price about 15% more on the SIP building of the same size. When you do eventually get a panel up it does grow quickly which after the effort of lifting and positioning is very welcome. Windows in the SIP were arrrrrh I won’t go there, trying to work out a pre prepared panel set to frame out a window was impossible for me so I cut out after complete panels were fitted as the windows were small and just the timber frame was all I needed was structural support. Kits are available but were £3000 more than just plain panels, expensive windows I thought. It is warmer inside and I like being in the building but I haven’t insulation the framed workshop yet. More expense to factor in.
