I remember but can't search for a thread several weeks ago that mentioned a building material that Dynamat is allegedly made from?
Can anyone name that stuff as I want to do a large area but don't want to spend the bucks.

Is this what you meant?
Available in different widths too. I tried to buy it from a local plumber's merchant and was quoted 4 times that price for half the length!!!:

Try phoning your local builders merchant(s) and ask them for flashband.

Not sure what it's likely to cost, but i'd say the screwfix price looks pretty good.

£9.99 @ my local merchants

 

I've tried some of this stuff but it has nothing like the weight and rigidity of the basic dynamat, nevermind Dynamat Extreme.

It needs to be a dense bitumen-based tape with a thick foil backing to be equivalent.

 

Thanks all - I'll scout a few merchants and look for some thick stuff.

Flashing is what you're looking for. I've used marley flashing tape before with some success.

A couple of points:
- it ain't as effective as "proper" stuff on a weight vs effect basis
- it tends to slide down panels when it gets hot...

Other than that, it's a cheap solution and is worth looking at.

Cheers,
Nick.
