Sliding window seals

    I currently have the 2 sliding windows out of my Viking camper. I have been trying to find a seal refurb kit so I can strip them down and refurbish them but I am unable to find my actual windows on any of the online suppliers sites.

    Is anyone able to assist as to where I can purchase replacement seals so that my sliding window runs freely in the chanel, does not rattle when I'm driving and actually seals the window from water ingress.

    I’m going to show my ignorance here as the only Woolies I know is where I use to go in the 1970’s to get my ‘Pick n Mix’ banana toffee swirls.

    I did this recently, not completely successfully though. You need to measure the width and height of the felt/rubber channel that the window slides in. Woollies is down the road from me so I popped in to see Duncan. He keeps a few profile sizes but didn't have the right one for my bus. Let me know if you can measure it and I'll see if I can find the details of the place I bought the correct one. I was trying to do it with the window in situ; got one done but it's too tight to slide open.

    Well, in some respects I wish I'd never started on the windows as it's been a right pain in the a##e to sort.

    The windows came out when I had some rust issues sorted and when I removed the rubber seals I saw what looked like dry black putty in the seals which just crumbled up.

    As my camper is a van conversion the windows are not recessed so I have 'Claytonrite' seals which have an infill strip which is what expands the seal and helps to make it more impervious to water ingress.

    After my van was repainted I refitted the windows using the old seals and they unfortunately leaked badly. It transpires the dry black putty I had seen was some sort of butyl glazing tape which helped to seal them.

    The fixed glass in side windows is 5mm thick, but the aluminium frames the sliding windows are in is only 2mm thick and the infill strip can't expand the rubber enough to stop the ingress of water.

    I liaised with 'Woolies' and they only supply/do one seal and as such I contacted 'Seals Direct' who provide a greater range. After lots of communication with them it transpired the best seals for my requirements were one for the solid glass and one of the sliding window frames. When the seals arrived I fitted the solid pane in the sliding door (a sliding window in a sliding door would just cause issues and a potential falling out of the window over time, hence the pane is solid). However when it came to the sliding window frames I discovered the wrong seal had been sent. This was soon replaced with the correct seal I had ordered but it became apparent that the seal was incorrect as the sliding window frame was not held by the seal as the web between the 2 gaps (gap for the panel of the van body and gap for the aluminium window frame) was too narrow.

    This resulted in me using the seal that had been sent by mistake (how lucky was that) and I inserted the aluminium window frames into the seal and prior to installing the infill strip I applied a generous amount of Polybutene permanently plastic sealant so as to make up the void where the aluminium seal sits in the seal gap.

    I am collecting the camper tomorrow and hopefully over the weekend the polybutene has time to set and the windows will be water tight.

    What I have learnt is that whom ever cut out the apertures in my camper for the sliding windows cut the holes to big and assumed the web of the seal was the same as for a piece of solid glass when in fact the web in the seal is thinner. It's all a learning curve.

  7. If you`re still struggling it`s well worth scrolling through here ...

    Very comprehensive range , i have a panel conversion with `oversized` window cuts and found what i needed - very helpful on the phone but the website will tell you everything if you`re patient :thumbsup:

    EDIT :- just seen you`re aware of seals direct but maybe of help to others ...:oops:

    This is a sketch I made of the old seal and panel thicknesses that I sent to Sealsdirect.

    Initially they recommended seals WR62 for the fixed glass and WR63 for the aluminium frame of the sliding windows

    [​IMG]

    [​IMG]

    I questioned seal WR63 as I was concerned a 5mm gap with a 2mm aluminium frame would leave too large a gap for the infill strip to seal it. It was then that seals direct suggested seal WR4930 but I did not realise at the time that the web in the middle is thinner.

    [​IMG]

    This resulted in a gap when the frame was inserted

    [​IMG]

    I then thought a strip of solid rubber (SN29) could be used to fill in the gap of the wrong seal that was sent (that I believe is WR61 or WR63) but that didn't work.

    So at one point I had 3 seals and a frame that did not want to fit in the aperture.

    In respect of the seals that make up the sliding window itself I used a rubber 'U' section for the fixed side of the window (US53) and some 25mm polyester sliding window strip (FWR5119) that I bonded in with silicone after cutting it so it followed the corners.

    So after installing the seal to the camper and putting the aluminium sliding frame into the seal I applied the sealant

    [​IMG]

    After which I installed the infill strip. The white spirit was then used to assist in removing the excess sealant and the windows left to set.

    At this time my sliding windows no longer rattle and are slightly stiff to move but glide silently and secure in place better than before.

    My only issue now is a solid infill piece that sits in the external 'U' section of the frame. I have been told it is no longer manufactured and so I have got to find an alternative.

    A bit of searching on eBay shows 10mm thick solid rubber and foam rubber strips .. and annoyingly a 9mm thick by 22mm wide solid rubber strip ( time for some precision work with a Stanley knife and a straightedge..)
