In a stick frame building, everything still gets clad with sheathing (plywood) and subfloor (thicker tongue and groove plywood).
Structural insulated panels (plywood/foam sandwiches) have been around since the 70s. They're a useful building technology.
There's no way they can provide an equivalent amount of product to a SIP cheaper. They're operating at small scale, and CNC machining everything which is expensive. The math ain't mathin'.
Building technologies do need to evolve, but this ain't it.
Starting with the tagline "Simple, beautiful zero-carbon building for everyone". WHAT?
- Claiming that timber building products are carbon neutral is dubious, just talking about the timber alone, before any value added lifecycle. They should put some pictures of the Spruce forests their plywood comes from and let people decide for themselves.
- Simple? Not really. They don't say much at all about what happens after you get walls and a roof. Who is going to plumb and wire, and how? How simple will it be to find a tradesperson who wants to actually figure out from scratch how to pull cable through your ikea home and put their license on the line?
- Beautiful? Meh.. ask again in 30 years and see if people don't say it looks like it was built in 2023.
And then just all the stuff that doesn't matter. The problem of making a building isn't putting up walls and a roof. That's usually the part that goes the fastest. Who cares that it's 'precision engineered' (spoiler alert, if it's OSB, theres no precision) and that it has 3x more compressive strength than stick frame. When was the last time you thought to yourself 'I wish I could put a car on my roof'?
That's the whole point of doing the exercise in the first place. You get hurt and have bad form because you are weak. Squats are not just for leg strength. They work the entire posterior chain. Any exercise has the potential to hurt you if you do it incorrectly.
After going through a web dev bootcamp myself where we actually devoted a decent amount of time to algorithms and their time/space complexity -- this has been the thing I have used the least in my professional career.
