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…

Hi everyone, I'm sure you all have an immediate answer/preference here, but can I ask what is recommended when looking at replacement windows and how window fitters seal the windows into the opening. I've just visited a site where a well known window company used Wurth expanding window foam, I was looking at the can being used and it's clearly designed for windows, has a fine cell structure and of course will fill every gap, especially around the spacers used to ensure a square mounting. On the other hand I was under the impression that expanding tape such as compriband was recommended but then I notice a number of forum posts which indicate difficulties with the tape, particularly if the gap is not consistent and how it works when butting up against the window spacers/packers and how to maintain an airtight seal with the tape. I wonder do some companies choose one method over the other based on installation speed and cost, and there's also the question of how well foam or tape perform over the 20 year lifespan that you would expect from the window itself. I would appreciate any feedback here from those more knowledgeable than me in this area, Best regards Richard. -
I have a smallish void behind plasterboard to fill. Expanding foam is the ideal product, but I really don't want to have to do more than drill a small hole or two into the plasterboard - cutting a large hole out of the plasterboard and repairing thereafter is not an acceptable option. I know the volume, dimensions and shape of the void. My thoughts are to drill two, perhaps three holes to cover the length of the void (600mm) positioning them such that I could angle the nozzle of the foam gun extension through an arc to get the best coverage. This would also in part ensure there was somewhere for displaced air to go. As I see it the main issues are going to be judging how much foam to squirt in (as I don't want over expansion blowing the plasterboard off) and ensuring a good cure given most expanding foams are moisture curing. I'm thinking it may be worth buying a USB inspection camera scope that I can plug into my phone so I can at least get some idea of what's going on in the void and to assist in curing, use a plant mister to spray in a little water into the void before applying foam. Any other suggestions?
