My kids alerted me to a crack on the window I fitted in their betdroom last
year.

In fact it is a series of cracks eminating from a single point under the
bead, probably the top centre edge of the panel.

They've sworn blind that they haven't hit it with anything and given the
apparent origin of the cracks, I'm inclined to believe them.

Now, it was my first glazing effort and I did have trouble, involving
removing the DG and doing it a second time. So it has been rather abused (I
chose a small window as my first on purpose).

So 2 questions:

a) I'm thinking a minor fault in the glass and/or the abuse I gave it.

b) (Worse) I'm doing glazing fundamentally wrong. I don't (hope) think so as
I used proper glazing packers, bridges and packed the DG in nicely without
forcing it.

and:

How does one measure a panel when fitted for replacement?

I have the invoice, so the company might have it on record and can just make
me another one. But if not, I'd rather not de-glaze to measure as I'll have
a hole in the wall for a week while I wait for a new panel.

Is there a way to determine size from the frame or the visible parts of the
glass?

Tim


PS

Cracks sellotaped to buggery for now, so won;t fall out and kill them.
Luckily it is only 2x1 ft ish so isn't going to be too expensive.

Could be any number of reasons such as a high spot somewhere, a bit of
debris between glass and frame, temperature variations etc - or even the
vibration from the kids loud boomboox :-) . Glass is a very touchy material
to work with.

Even the pros get the same problem.

I know you are reluctant to do so, (but presuming that the information is
forthcoming from the company) the easiest method in your case is to simply
remove the beads and measure the glass in three dimensions (length, breadth
*AND* thickness) and temporarily replace them when that is done (it
shouldn't take long and the glass unit should stay in one piece).

When you fit the new unit, ensure that every thing is clean and free from
any high spots between the glass, frame, rubbers and beads.

of the glass?

There is, but you will have to do a certain amount of guesswork with regards
to the thickness of the packers, thickness of the unit etc.

I would worry too much about that, the construction of the unit usually
stops 'cracked' glass falling out - especially one that small.

Thanks for that. I'll be super careful about cleaning the strips and
checking it next time.

OK - ta. I have plywood available if the worst comes to pass when I take it
out. But I'll phone the supplier first.

Is this a fixed or opening light?
I assume you left a reasonable air space above the glass?
From the instructions from various sources I followed when doing my glazing
there should be nothing touching at the top centre, and I think a reasonable
space.
The diagram I followed showed a fixed light resting on bridge packers at the
bottom, and an opening light packed out at most of the corners.
I was initialy amazed at the amount of air space around the glazing unit,
but less so after I had used various frame fixings to secure the frame.

Hi David,

Fixed.

Yes - 3-5mm.

From the instructions from various sources I followed when doing my
glazing there should be nothing touching at the top centre, and I think a
reasonable space.

Nothing I know of.

the bottom, and an opening light packed out at most of the corners.

I was careful to make sure the glass didn't touch any screw heads. This is a
lower light, so definately no fixings on top.

Possibly a manufacturing defect then.
But difficult to prove.

If the supplier has your order on record, they will know the window
profile that they supplied you with. This is important.

If that is the case, measure from the outside of the glazing bars left
to right and up and down and they can calculate the size of the DG unit.

Seen this in a Patio Door at work. I would suspect a pressure point on
the frame - perhaps a piece of grit trapped in the bead.
