Damming tape of the right width and height hopefully!Tim - what are you going to use for the damming tape? It needs to be the right width and height.
Steve - I bought an ACC "mastic with pad" insulation kit along with the carpets from Rockauto. It's pretty thick and much cheaper than Dynamat.
I used a foam glazing tape when I refitted my screen a few years ago. I hadn’t ever seen it done that way before for a car windscreen but I used to work in the window industry and at one time glazing tape was used a lot to hold in double glazed units. Holding the glass away from the frame at the right height is critical or you’ll get a gap when the chrome goes back on. I think I used a 9.5mm thick double sided tape, closed cell (open is not waterproof). I stuck the tape to the frame then glazing sealant to the outer side of that. If you use double sided tape then you only get one go at dropping the screen into place, but I wanted to know the screen was going to be well held in.If you find that article, I have another couple of questions:-
Should the tape be self adhesive on both sides (like glazing tape), or just one?
Why stick it to the glass, not the windscreen surround?
Oh and any idea where you can get this tape from, if it's not just glazing tape?
I gunned a fat bead of sealant next to the foam tape before dropping the screen in place. With screen in place I then smoothed the sealant into the gap and then gunned in a bit more if necessary to make it neat. Can’t do that along the lower edge obviously, but not critical there.Hi Andy, I remember you telling me that's how you'd done it. Did you apply the sealant after putting the windscreen in place? I can't actually find anyone selling damming tape, Ecklers and the like sell a butyl adhesive strip instead. Presumably all I need is closed cell foam with single side adhesive in the right dimensions (whatever that is), but then I also need to know how much it will compress to get the height right. Think it would best if Tim gets a shift on and does it first
Definately, but if foam tape is used as a damming strip, there’s not actually much width left for sealant...not like the 1” wide patch on a modern car. I used double sided tape as opposed to single sided to get some extra adhesion from the taped area also, for what that’s worth!I think the modern urethane windscreen adhesives are stronger than double sided tape. A lot of modern cars use the glass as a structural element
Not quite that easy, this site only wants to sell to businesses and they have a minimum order of 12 rolls. Of course if you'd like to buy the 12 and send me what you don't need .Just google windscreen damming tape.
These CRL Foam Windshield Support Tapes have been used in the past as a support device when using medium viscosity urethanes, but is now a required item when replacing numerous windshields that need additional sound proofing in order to keep wind noise to a minimumwww.crlaurence.co.uk
