Been looking at switching to natural materials for my cottage renovation. Sheep's wool seems popular now but I'm not sure if it's a DIY job or if special installation is needed. Also wondering about cost difference compared to standard rockwool.
You can definitely DIY sheep's wool insulation if you're comfortable with basic installation - it's more forgiving than some materials - but a lot of people hire it out because it needs proper moisture management and you want to get the density right, especially around edges and penetrations. Cost-wise it'll run you maybe 30-50% more than rockwool depending on where you source it, but the longevity and breathability tend to make folks feel like it's worth the investment for renovation work like yours.
Sheep's wool is totally DIY-able if you've got basic handyman skills - it's forgiving stuff and doesn't require special equipment like rockwool sometimes does. Where people trip up though is thinking moisture management is optional; you really need a vapor barrier setup that works with how sheep's wool breathes differently than synthetic stuff, or you'll end up with damp issues down the line. Cost-wise you're probably looking at 30-50% more upfront compared to rockwool, but the longevity and environmental angle appeal to a lot of cottage folks. Are you looking at batting or loose fill, and what's your wall situation like - that matters for the moisture strategy?
