I have done it once by sliding a wallpaper scraper between a pane and the divider, you may have to peel the tape off first and use a block of wood to knock the scraper along.

 Bit scary tho'  :shock:

Spiltting may not be the greatest problem, although I suspect they are sealed with something quite strong.

Cutting may be you're biggest problem, as , if they are patio doors, it could well be toughened glass for safety purpose.

The panes are vacuum sealed, but the seals do split or develop holes. It's not hard separating the panes, but like DD says, they're a beast to cut smaller because the glass is thicker than normal. I've never found it worth while, nor safe, to bother. Always take my old doors and extra large windows to the dump and look for regular single pane windows or glass while there. If you want to try cutting that glass, be very well protected because it breaks in large, very ragged pieces otherwise.

I had (and still do have) exactly the same problem Aunt Sally! It's been a nightmare to clear it all and I'm still finding lumps all over the plot. I'm gonna stick with plastic and perspex.

Hi Trillium are yours vacuum sealed then ? I know ours are not, I used to work for the ones that "fit the best, fit ........." and asked this question my self once.

I got hold of some double glazing to mess around with, anyway cut a long story short I merely laid it down slowly and gently end up onto the drive and it shattered in a great whoooosh!  :lol:  Millions of bits on the floor with the frame left standing. I presumed it was toughend glass which i just happend to catch right (or wrong) and it blew.

My OH takes the old secondary glazing that the fitters bring back in to the window and conservatory manufacturer I clean for.  There's always lots of it.  Do you have any around your way?

He always moans about the double glazing being a pain (ha ha, pain get it???) to re-use and being toughened doesn't help.

Yes, all of them, otherwise, what's the point of 2 panes of glass without an air seal between to block out the transfer of hot or cold air? The latest technology now seals the 2 panes with Low E (argon) gas, which is even more efficient at maintaining inside temperatures.

Thats interesting ours rely on Pilkington K technology which I presume does much the same as your argon gas.  8)

Probably does. The Argon gas is highly rated as a very low emittor source of pollution (Low E). Somehow lack of air doesn't work the same as the gas does.

lack of air makes large panes concave inwards towards eachother so the gap is smaller.

Well, that goes to show that some know how to fix toasters, and some know about window glass  :lol:  :lol:

the reason the the unit is sealed and filled with gas is to stop it steaming up (condensation).once the unit has failed it steams up between the panes of glass.

Being an inert gas - that's understandable! :lol:

Went through all my years at school being told that nothing reacted with an inhert (noble) gas to make a compound.

When I started work at a large lighting company I was introduced to......

Xenon diflouride!

Guess that is why glass is banned on our allotment
