National Windscreens is hopeless

I had a cracked windscreen replaced by National windscreens....twice and the problem is still there!

There are gaps between the applied PU sealant bead and glass along the top edge.

It seems to stem from the D2 screen's built in rubber shield/seal along the top edge. It prevents the screen from naturally seating down on the PU sealant. I have seen pictures of others doing it with straps/tape around A-pillars resting on big blocks positioned at the top of the screen to force the glass down.

Has anyone advice as to what I should do? I don;t think the clowns from National windscreens have the ability to figure this out. I am thinking perhaps I can remove the headliner and seal the gaps from the inside.

I should also ask my money back as they did not supply something fit for purpose.

Make them do it again.
My son had his done by a chap who used to spend his day refitting them for warranty work when new. He used plenty of glue and the seal to the roof fits good and nothing leaks.

They replaced the windscreen on my old disco 2 in around 2013. It had a heated windscreen, which showed on the spec when I called them and was confirmed as a straight replacement. The guy turned up with a non heated screen, saying they didn’t have a heated one in stock and did I mind a non heated screen! Needless to say he was sent away to come back with a suitable one.

The following week, two different fitters turned up and did a decent job.

Did any of you guys have fitters strap down the top of the screen or somehow apply additional pressure to seat the seal properly? The guys I had clearly never did this. I am pretty sure all of the D2 screens they fitted were not sealed along to the top edge.

No

I have now finally a windscreen fitted with no gaps, leaks or holes. Hallelujah!

To overcome the insufficient depth of seating along the top of the glass they first pre heated the top rubber strip with a heat lamp to soften it. Then they installed the glass with ratchet straps and suction cups on the inside of the vehicle to pull the screen inwards along the top edge.

One thing I learned in this process is that pretty much all windscreens fitted without these steps (ie. all mobile fitters) will inevitably have gaps along the top edge. This I believe will give rise to leaks and wind noise. Once my screen was correctly fitted there was a very noticeable reduction of wind noise.

Additionally, it is not hard to check your own windscreen by inspecting with a light pointed up into the top joint from within the cabin. The headliner is sufficiently clear of the glass to allow this.
