Insulation general
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?
