Rear windows in hardtop - noise issues?
Considering fitting rear windows to my 90 H/T, just wondered wether anyone who has done this has regretted it afterwards?

Is there any increase in road or draft noise from the windows compared to a hard top? My Td5 has got a bit of soundproofing behind some TGE rear interior panels, I'd fit some Masai tinted/sliding windows and plastic panels around the inside.

We fitted some used side windows from eBay to our HT, no trim in the back at all. Took our time, sealed them well with quality silicon. No leaks, no noisier, just a lot safer at junctions. Dogs love the improvements!

Thanks Grumpy,
Our dogs would love it too, plus the safety element.
No regrets then?

No, none at all. Well worth the £41 it cost us, some people end auctions at daft times don't they? Whistle

Loads better, more visibility and easier to find things in the back. SWMBO is a gardener and is often rummaging about in the back trying to find stuff. Not worried about the perceived lessening of security as IMO they're always going to get in if they want to.

If you do decide to go for it you can get black 4.8 x 12 (I think) black pop rivets and the filler strips are only a few quid, MUC1005.

I measured the sides, lining up the top to where I thought it looked best then made a template out of a piece of 6' x 2' hardboard so it just cleared the inner lip. If you're using internal trims this will help you work out the alignment.

You'll need to remove the stiffeners either side, drill off the rivet heads with an 8mm bit then use a wallpaper scraper or similar to remove the bonding adhesive.

I transferred the outline to the panel with a fine permanent marker then cut out with a 1mm slitting disc and jigsaw for the corners. Quick tidy up with a file, fitted the window and drilled for the rivets in each corner to hold it steady. Drilled the rest of the holes, using the rivets to hold it in place while I drilled all the holes then a good bead of silicon on the panel edge and frame and riveted all around in a cross pattern starting from the centre. Not a bad job to do Thumbs Up

[trim to cover rivet heads yet to be fitted]

They are the Masai fixed windows and it took about half a day to do. Honestly, I was not impressed with the quality. The paper template was £15 and being paper it was about as useful as a chocolate teapot. It really needed to be card. That aside, I am not convinced the rubbers are right as they rattle like hell and if you push the rubber seals in tight with your finger tip they are quiet for about 2 miles and then they rattle again. Trouble is, windows are not the sort of product you can send back for an exchange or a refund!

Safety-wise they are a bonus and I did this for the good lady as she was terrified of bumping my pride and joy and we felt windows made it a little more user friendly. As for general noise levels - I would say mine is about the same before and after (if I do the trim squeeze first). I do have silent coat and closed cell foam all over the place so I wouldn't have expected it to be much different. Ironically, I bought fixed windows to avoid the rattle but these are dreadful and noisier. I am on the verge of getting out the silicone on a warm day and gum them up to try and stop the rattle.

If you do buy Masai (I wouldn't again), I would have a very good look at the seals and be comfortable they are right before you cut a hoofing great hole in your van as it is a little bit late to find a problem with the window as you are fitting it. As for their £15 template, save your money and measure it and mark it instead. It might be slower but it will be better in the long run. Phil

Oh dear, sounds like I might have had a lucky escape, not ordered anything yet, just thinking of doing. I'll keep my eye out for a genuine set or look at another supplier, I had a quick look on Landyglass but they don't seem to do replacement rear windows unless it's the panoramic ones

Has anyone else had experience of Masai Windows? I notice Britpart/Bearmach also do them now too.

I converted my 1984 HT in 2000 with OEM windows and Simmonites version of the factory interior side trims, I already had a County roof with full headcloth. The rear had been checkerplated by the previous owner but I fitted a full set of inward facing seats as well.

Basically the motor is now quieter than before because I no longer have the booming noise from the aluminium side panels vibrating, and that's despite running a 200Tdi!

Thanks for the replies, I've now found an old pm from mark1collector, he said he was very happy with the Masai windows, I suppose orangesofa could have had a badly made pair, it happens.

Mine are still working great with no leaking or noise, but mine were the slider version so can't comment on the fixed that orangesofa has Ray

Hi Lambley,
You may have decided / done, but I went from this:

to this:

as T3 had to live in Switzerland for a while and side windows are an absolute must on a right turn in the EU
I used a mechanic (Gumtree 4x4) and, to my spec they put in sliding units. They are good.
I'm in UK now and any gubbins in the back has never been a security concern to me. The rear door can probably be opened with a safety pin Whistle
They make no difference to the noise of a diesel truck with limited sound proofing!
Of all the mods I made the windows were the most benefit - visibilty is safety. I also now have larger side mirrors and decent headlights. And my friend, a 57kg lady in her 60's, will happily drive it. Must have got it right ! Sold the much modified 110 2.8, in Oz
Brought the 90 home from Switzerland ...

Thanks ppad, looks good, I'm still going ahead, I bought a genuine set of L/R tinted privacy sliding ones, unfortunately I'm not 100% happy with them, there's a couple of small holes in the tint that I wasn't aware of so I'm going to return them, but I'll definitely be fitting some shortly Thumbs Up
