Fixing Windows with foam

[camerart]

Hi,

I'm fixing a PVC window, and have just cemented up the brickwork. I intend to use Fixing foam. How long do I need to leave the cement to cure before using the foam?

Cheers.

Have you put screws in to secure the frames?

Hi Andy,

No screws. I just want to use fixing foam.

You need screws as well, foam is just for filling gaps, draft proofing and keeping everything in place using only foam is a bodge

I am worried about the weather changing without proper security at this window.

I am an amateur and am most probably not doing it how a builder would do, but if I can fix it quickly, then strengthen it all afterwards with screws, this would be better for me.

I realise I would have to fit, remove and re-fit the glass.

Use some masonry fixing screws as shown on this page, no need for plugs. If you don'fix before you foam you will have all sorts of problems

Thanks for the link. I have used this sort of screw before.

I have to fill the cavity wall before fixing the window. (It was a door)

So it is only just being cemented, so I can't drill it yet. There is an existing section where I can fix it with foam. I can then fix it with these screws after wards.

I just need to know how long I need to leave fresh cement before using foam on that bit.

Just board it up from inside with OSB board let the cement go off properly and then fix the window, and then use foam

OK, Thank you.

Structural fixing foam is available.

I have structural fixing foam. Does this change the last recommendation of waiting or do you think I can fix it with foam first then reinforce it later?

This would be much better for me.

I prefer foam first it help prevent movement/distortion when screwing thru frame .

Perhaps it's not the proper way, but I did fix it with dots of foam while the cements cures. Today it is quite firm. I can fix it properly later.

It would have been really difficult, to do it properly under the circumstances, and needed to compromise, even though I would hope any proper builder wouldn't do it like this.

Thanks all.
