Sealing Gaskets windows.

[Adam2050]

Can you try different seals from the ones fitted.

I ask because of a single layer gasket like the one I have fitted. Isn't going to produce as much thermal protection as one with two layers? Mine is the R4055, was thinking maybe the B009.

Windows open from the bottom out, they're in a loft dorma.

Thanks

You could buy a sample pack and try different types, obviously this won't indicate what it's like to have the whole unit sealed but might give you an idea?

Double Glazing Seal / Gasket Sample Pack (handlesandhinges.co.uk)

I just found that site with a random Google, if you type in gasket sample pack you've find other suppliers that might suit your requirement more.

Yes seen the packs again I agree you won't know until you try. I'd assume it's tension all round and fit in the groove.

I can't comment on your exact windows, however normally with gasket you don't want to stretch it when fitting. It should be installed under its normal tension if that makes sense?

As diy_fun_uk says definetly don't stretch it , or it will eventually ' shrink ' back and leave a gap. Gaskets are one of those things that are incredibily hard to be 100% accurate about as a replacement , as they are measured in such small sizes and each ' groove ' they go in can be different ( eg that B009 may well just slip out of the groove being 0.6mm narrower ) . Best bet is the gasket samples , readily available on the likes of Evil BAY, but bear in mind they are only a small selection of gaskets available. And in answer to your question about which one is best , as long as they keep the water and wind/air out , it will make no noticeable difference . One is a ' bubble gasket ' one is a ' flipper ' gasket , and they work is differing ways

Surely more material, in general, will offer more resistance to water/wind especially from a thermal point of view. I guess I will have to measure the gasket more closely and make a choice and do a bit of trial and error. At least it's not a generally expensive material to play around with.

Maybe try speaking to someone like this for advice based on your window design? It's not necessarily about more material in all cases, it's about ensuring you have the correct gasket for the window in terms of how the openers open and close/seal.

There nearly 30 years old and on the property when I bought it, think it's safe to say they no longer are trading. The ones in question are blown a little in the corner of the main pain, so it's probably just getting on with it myself as a short-term fix.
Thanks though.
