Sealing double-hung sash windows

[LeftyJim]

Hello All,
I am in the process of trying to seal up all sources of cold air entry into my 50's red brick house. All of the windows are the double-hung sash type, and luckily, are in reasonable condition. The biggest problem with them is the gap in the seal between the top and bottom sash is anything up to 5mm when closed, which allows quite a bit of airflow. The sashes are also rather loose in their frames, and rattle when a loud car goes past :eek:

Has anybody come across a seal conversion system to suit sash windows ?
Something which replaces the running surfaces with some sort of sealing material, but still allows easy movement ? I remember seeing a product on 'This Old House' some years ago, but I don't remember if it was something local to the house they were working on (in the States of course) or a widely available product (US) that may have made it's way down here.


Cheers,
James

Welcome Jim.

Interested to hear responses to this one, I have the same prob, gaps not quite that big but still a fair amount of air leakage.

G'day scooter, all,

To add a bit more detail, this is the type of thing that I am looking for: http://www.mwwindows.com/pdf/rpinst.pdf

Anyone ever seen anything like this available in Australia ?
Is it another case of too small a market and too pricey ?

Cheers,
James

Hi, Have a look at Raven door and window seals. They have all types of seals for windows and doors. You can buy thier products at most hardwares.

The web site says, RP61 type seal for double hung sashes

I agree that Raven are probably the best to look at - I used the product which looks like a long furry strip (RP61) and put two strips on the window, one one the outside of the top bar of the bottom (inside) pane and one on the inside of the bottom bar of the top (outside) pane - they are opposite each other and completely hidden when the window is shut and provide a pretty complete seal and stop rattling - the only downside is that the rattling is still there (but not as bad) if the window is open.
