Winter is coming! What are you doing to stay cozy/save on heating costs?
Me? I'm currently in the middle/at the start of various projects on the house I got.
>Windows
I'm changing the gaskets, they're done and leaking heat, just gotta figure out how to adjust the windows to get rid of the remaining gaps.
>attic
Already got a big-ish layer of rockwool in it, but apparently, nowadays you're going thicker. Contemplating if I should just plaster the whole area in a few cm of XPS, which would also give me a better walking surface and the option to store some stuff, without producing stupid ass rock wool dust.
>pipes
Not really worried about pic related, but my heating system in the basement has all its pipes uninsulated. While it does warm up my basement, the fact that the basement itself isn't really insulated does waste quite a lot of heat. So those pipes gonna get covered. Just wondering if it's really worth it to shell out for armaflex, or if I can just get random PE or rock wool insulation of my local big box store, which costs half as much as armaflex and seems to have a better λ as armaflex. For armaflex, I can only find λ ≤ 0,036W/(m·K) at 0°C at the various stores that sell it, but for the cheapos, I get about λ = 0,037W/(m·K) at 40°C, and armaflex lists 40°C only in their datasheet for all their products, and there its at 0.041, so worse. What gives?

The point of armaflex is outdoor, weather/UV resistance. There's no reason to use it indoors, other than maybe better longevity in theory.

Careful with rockwool. Well documented to cause lung issues. If you're not comfortable working with it call an accredited installer and they will be able to take care of the installation for you no problem.

>shell out for armaflex
this is generally so the ambient temperature of the room your heater is in doesn't leach temp from the hot water you're using
if your heater is set to 120, by the time the water reaches your shower it's down 10-20 degrees from ambient loss along the pipe path
armaflex helps that

>comfortable
Not really. I hate that shit. But nothing a pair of gloves and a good mask won’t take care of. But for pipe insulation (which is covered in aluminum foil as a top layer) I don’t expect that to be a big issue. But I guess for cutting and going around curves PE foam and armaflex is way easier to handle. Just some cheapo cutter knife.
>>2943389
I know. I’ll also do my warm water pipes, but heating is the main issue. Just wondering if armaflex is worth the extra €€€. I’ve worked with it at a job before, so that’s why it’s my go-to, plus, the stuff you get at the big box store tends to be the lowest quality, but in the other hand, a foam tube can’t be that hard to make good enough?

>foam tube can’t be that hard to make good enough?
right. i see. yeah i men, foam is foam. even 30% more efficiency isn't noticable in our context and I highly doubt there's that much variance
