I really think many people don't pay enough attention to insulating homes they think solar panels, heat pumps etc.. But don't think of why the house is too hot or too cold. It's all just moving energy around cold is absence of heat but you hear of people say "cold is coming in" really it's heat escaping.

I'm going to try my hand at insulation my parent's home. Dad died last year he built the house and everything in it and on it. He was sick for 15 years so maintenance was difficult.

I'm looking at Rockwool for the attic most heat is lost through the roof. The pull down stairs are terrible for heat loss. Heat bridging is also what I want to tackle too I'll cover joists perpendicularly.

Stuffing the attic with insulation is easier than solar or a heat pump. For now.
