Any crack repair is a temporary fix until you replace the unit:)

Get a new unit. The glass isn't actually as expensive as you might think.

The window measures 220cm X 120cm so i'd imagine your talking a few hundred?

Claim it on the house insurance.

So, thats what insurance is for surely.

A double glazed unit that size would be probably between 500-750 possibly
depending on the spec.

Why have insurance if you dont use it for what its for

I agree with the theory but lets say its 500 lids
his policy is say 1000 and they add on 20% for 3 or 5 years: the question on the forms are any claims in last 5...

If the chap has limited funds, and the glass is going to be expensive, plus the fitting,
then he may have little option but to claim.

I agree that an insurance claim would be a last resort, but its about circumstances and costs.

That size pane will no doubt be a 2 man job to fit due to weight.

Try the repair first, it might stop the crack from running longer and might stop moisture entering into unit cavity and misting up in between the panes.

Crack repair is a total waste of money, its only advised for a temporary fix, until you get the
replacement unit.

But if its for short term, go for it. You will probably need a long lead time for that large unit anyway.

4 weeks for double and triple, but also there is a builders' holiday coming up.

there isnt a vaccum in double glazing, there is air inside.
a-rated units have the air replaced with argon gas.

Probably meant integrity of the unit.

Which is correct, once compromised its no use.

If there is no condensation in the unit I would be tempted to try the repair.

From a pure safety point of view I dont know why anyone would try to repair a cracked double glazed unit.

As basil says, its kaput, its dead, it lives no more.:D

A large piece of glass thats cracked is a dangerous thing. Winter frosts and changes in temperature
will make short work of a a 20cm crack turning it into a 200cm crack, instantly.

It might not be claimable under the policy?
A crack from someone throwing a stone, or it developed somehow?
By the time you factor in the excess before a claim is paid out and then what you'd lose in your insurance going up, I'd look into replacing it themself first.


I'm not certain thats what insurance is for, or if the policy covers it, if it is necessarily worth it. I have window cover on my car insurance and it doesnt affect my car insurance if I need to use it, not sure if such a thing is available for a house or necessary.

Is it possible its under warranty from supplier..

There was a bit of a fuss a few years ago where large DG units were cracking all over the place. Turned out to be a manufacturing issue.

The unit is over 12 years old.I'd love to claim on the insurance but i don't actually have any insurance.

You dont have buildings and contents insurance?

I cant see a situation where that would work out well.
I'd start getting insurance cover before I sorted the window.
Honestly, I'd get a sheet of that laminate stuff to do something about safety, I'd look at repairing it myself, and go to you tube for guides and adverts/donedeal with measurements for glass or free/cheap panes.
I'd cut back on a lot of things to get buildings cover, unless it is not your building to cover of course.

Its not a one man fix due to its weight. That size of unit may be up to 100kgs, depending on its make up.
This is a recipe for a potential serious accident.

Its no wonder accidents occur, when professional advice is dismissed, in favour of a diy recipe.

When this fix goes pear shaped, be sure to open a thread on how to re attach your hands, due to an accident trying to fix a heavy glass panel.:eek::D
Hopefully you will get a diy method for suturing:p

I'm done.:)

Well, Im suggesting they prioritise buildings and contents cover over a window.
I can see there is a risk of problems, but not having home insurance is bigger imo.
It appears if they had insurance they would deal with it that way, and it may have paid off as the additional cost will be socialised to everyone.
(assuming it is covered for in their policy).
Regardless not having buildings cover is risky.

It's a chip.

How does a 20cm crack, turn into a chip???

IT'S A CRACK.
