Hi,
I've been doing a few runs in the van and found that at 50 miles an hour it gets a bit loud, at 55 I can't hear passengers in the back and at 60 ish it's pointless trying to listen to anything including the radio...is there a way to muffle the noise apart from driving slower?

Sin

Lots on youtube with methods/materials. Its not T25-specific. Lots of ways of doing it depending on budget.

What sort of noise is it?

If it's mechanical noise, what engine, and how much insulation do you have around the engine bay?

Have a look at Lloyds "Getting There" post in the Syncro forum, he has posted some pics on how he did his, looked good......it may take a while to find the pics though

What Adrian said.

Mechanical, wind, external, vibration etc. The van interior will act as a boom box/speaker cabinet and you want to stop any external sound getting in and kill any sound bouncing about the inside.

Check door/window seals are good and tight.

Exhaust/inlet tract is as it should be. If it's a diesel make sure cam/pump timing are bob on- that will stop some vibration.

Silent coat is my new favourite, 25% coverage is ample to stop panel vibration - you don't need to wallpaper the van in it

Bulkhead over gearbox and engine bay/lid you could use one of the heavier vinyl/foam type coverings (same idea as the rubber/foam oe mat in commercials.

Put some in seat boxes under seats.

If you have a panel van, cloth covering the panels will absorb sound.

If you have a camper, make sure sink./cooker etc is stowed tightly with anti rattle stops.

Etc etc. sure others will add more

My camper is far too noisy, but I don't think, short of stripping out the interior and applying sound proofing everywhere, much can be done. The engine cover, for example, sits under a well fitted 3 inch foam mattress, so what's the point of adding more sound deadening material to the engine cover itself?

My cost effective solution has been to install a 1.4kW sound system with a boom box in one of the cupboards. This system, by following the DIY route, only cost around £200, and I can now happily listen to music whilst cruising on the motorway without the added distraction of hearing the advice from "back seat drivers".

Thanks for all the info, I'm going to be buying some of the sound proofing matting/foam to put inside the door panels to start with and will give it a test ride and then add to it as I go along...im not particularly savvie when it comes to car/van things

Have fun getting into the door then.

Each panel only needs a decent sized pad or two to damp any resonance, it doesnt need to be seam to seam coverage.
