Eventually, I will be replacing the rotten single-glazed windows in my Small Mission Hall in the Outer Hebrides. However, until I get planning permission/warrants etc. sorted, they are what I have to live with.
To make it slightly more windproof when the breeze gets over 60mph 🤣, I want to try and seal some of the gaps around the frames and the solid stone walls. Is some form of expanding foam the way to go, or are there other options I should consider?
Am I right in thinking expanding foam is not that eco-friendly? Are there options on that front without having to spend a small fortune on what will ultimately be a temporary disposable fix…
