Sealing Windows

barry75

Hi
Could anyone tell me what way to go about sealing up the gap around the windows in a timber frame house.There is a hell of a draught coming in around the opening.I was think of stuffing knauff fibreglass insulation around the window,or the other way was to use expanding foam.What would ya recommend?

Expanding foam is the way to go.

Yes, expanding foam. watch out that stuff really expands!!

You can get low expansion foam (window fitters use it) or have a water sprayer to stop the expansion when needed.

Hi

I have just gone through my entire first fix shell applying expanding foam to all of the windows (both sides).

I understand that windows are often fail points on airtightness tests and I wondered how difficult it would be for a novice like myself to use the special tapes to tape the windows.

Has anyone done this themselves or is it a job for a specialised contractor ?

Cheers

I did it myself, under manufacturers instruction. The principle is straight forward - tape, seal overlap. Have a chat with your supplier and study all photographs in manufacturers broucher / pdf / video etc

Some manufactures run 2 day courses.

Try Siga.ie for tapes - fairly easy to install if you are careful.
As posted before - although it looks you are beyond this now, I would advise using the Hilti air seal foam, as it remains flexible/ airtight and 'goes off' fairly slowly. That's the pros, cons is the expense.

Hi, I'm trying to find a company which supplies liquid rubber sealing for wooden window frames. There was such a company back in the late 80s and I got the windows on my old house done then however I can't find an equivalent now. This product was applied by the installers, it was a liquid rubber which was pumped into the window apertures and it adopted the shape of the wood. It dried over a couple of hours and was trimmed to fit. It worked very well and I'd love to get it done again. Does anyone know of such a product please?
Thanks

Hi, could you ever tell me where to find a company which supplies the expanding foam please? There used to be a company who filled window apertures with liquid rubber (which set quickly) but it's 20 years since I was in contact with them, I can't remember their name and the chances are they don't exist any more. Any advice please and thanks?

Try any of the car accessary shops, there are several liquid "rubber" products that may do what you want.

I have used RTV sealants before and they sound like the product you describe.
