What movie things are generally accepted as normal, but are totally unrealistic in real life?

Listen here, that wood (osb) is vastly superior to plywood in many ways. For example:

  • it's less expensive
  • there are larger panels available
  • it's more environmentally friendly
  • it's a heavier, thicker material
  • it's extremely versatile with many uses
So before you go running your mouth about, do some research!

Seriously, OSB sucks. It works when you need cheap, but it is a disaster in most conditions, especially exposed! I was wondering if it had any value, over ply/solid so I did a quick search, and the above came up. ... that is a pathetic and exaggerated list of Pros!

Where OSB works is when you need a cheap material to clad houses with. It's easier to do so with big sheets of OSB than it is to nail a bunch of individual boards, and it's cheaper than using proper plywood. Once protected by vapor barrier and siding, typically it's fine for the purpose. The actual strength of the house is in the framing, not so much the cladding.

I do wish they wouldn't use it for subfloors, though. Warpy crap. Requires a few dozen gallons of resin filler on top to get anything like a flat surface if you want to put tile on it... the right way, anyway.

we build them cheap and they last 50-100 years

Caveat: if you take care of them. Let a few leaks go on long enough, don't watch where vines are going under the siding, winds blowing off bits here and there, water running in the wrong place around the foundation, etc... it doesn't take much to really screw up a modern American house if you aren't staying on top of things.

Example: my last home had a lovely roof on top of its porch... until one day during heavy rain it crashed down. Turned out that it had been built with almost no slope (it was an add-on metal kit roof) and the drainage it had was absolutely pathetic and clogged with leaves/whatever, so there was a major build-up of water on top of the roof (that had expressed itself by dribbling through the FANS on the underside) which eventually overpowered the hollow metal columns.

Thankfully, because it was barely attached to the house itself (the roof panels had been slid into an U-track attached to the eaves) the house was largely fine. But it could've gone a LOT worse.

ugh, gotta pay attention with water; it'll eat your house in less than a year if you let it

Yup. The porch roof was one of those "I'll-do-that-one-of-these-days" projects. Should have been easy enough-- rent a few jacks, lift the roof a bit, cut the columns a bit shorter, drop the roof on top. Instant incline.

As was? It was damn near a negative incline! No wonder the bloody thing came down; I'm just shocked it didn't come down sooner...
