Look, we’ve all seen it—a job that got done in an afternoon when it really needed a proper afternoon plus half the next morning. Attic insulation is one of those jobs where shortcuts hide beautifully. Not many will go into every corner above to check what’s really there.
Here’s the thing as you know: if there’s no insulation in parts of your attic, or it’s thinner than it should be, moisture gets clever. It travels into that roof void and finds the first cold spot—usually your ceiling—and that’s when damp patches start showing up. Not always immediately. Sometimes it takes a wet winter to reveal what’s been happening quietly above your head.
If you’re fitting Isover Spacesaver Combi G3 (good choice—that mineral wool’s solid), you’ve got options from 100mm right up to 300mm, all layered properly between and over your joists to avoid cold spots.
