Fixing a UPVC door using foam? Anyone done it or have stories to tell?

We were somewhere around Barstow, on the edge of the desert, when the drugs began to take hold. I remember Cordless Crazy saying something like:

It's a standard way of fixing most DG units (with the aid of a couple of weedy brackets), just make sure you don't use too much else it can distort the frame as it expands.

Anyone used that Fischer 2-part foam designed for fixing door and windo

frames in lieu of using regular fixings?

What do you reckon

-- Cordless Crazy

It is probably a good structural fixing.

What is to stop a thief cutting it through with a hacksaw blade and removing the entire frame in silence?

Just use chewing-gum, since you're in France at the moment.

The render you put over it afterwards.

Would regular expanding foam do, or is the Fischer stuff better as it designed for it? (Am fixing a DG unit of size 2400w x 2100h

-- Cordless Crazy

In silence? - you've obviously never tried to remove a PVC frame that has been fixed in with foam...hacksaw blades to start (which incidentally sound like a pig giving birth, except they are much louder), then many, many hits with 5lb lump hammer onto 3X2 timber against the frame, this causes the whole thing rattle and vibrate and sounds similar to a washing machine being pushed down a staircase....this is all done with the glazing units removed, I'd hate to think what it would sound like fully glazed.

What the fudge?

Is this any different to fixing using normal 1-part expanding foam ? Anything special about the 2-part ? Simon.

Not really, except that it is applied using a mastic gun, the outcome is virtually the same, except you don't need to buy a foam gun

'French' doors.

So why does a 2-part have to be used in a gun? I thought the mai difference was the strength once cured? The 2-part is more of structural solution as opposed to the 1-part?. Or am I barking up a expensive tree

Ahhhhhh. Kerching....the penny drops!!!!!!!!

-- Cordless Crazy

It's 2 part because it mixes in the nozzle to become foam, if it was premixed in the tube it would set, the reason why it doesn't in a pressurised container is because the solvent is present, which evapourates once expelled....AFAIK there's no difference in strength.

Just remember Hoffnung's "French widow in every bedroom" and you can't go wrong...
