Cracked window - 1 month old

[Lydia94]

New bi-fold doors fitted less than a month ago and crack has suddenly appeared.  We have contacted the fitters and manufacturers, so just waiting on their response.  In the meantime is there anything we can do to stop the crack getting worse?  The crack seems to be on the outside pane of the double glazing on the inside of the glass, if that makes sense.  Also, apparently the glass isn’t covered under the guarantee, which seems odd, or is that normal?

Installation or manufacturing defect, quite common tbh. 
 

They should exchange that in a heartbeat, so I’d not panic.

 

It’ll get worse, nothing you can do other than don’t open / close it, if you care that much of course. If the opening ‘door’ part of the bifold is the other end, then using that will have no affect, but if this is the ‘door’ then every time you open and close it you’ll see this crack grow.

 

Let us know how you get on.

It’s consistent with a stress fracture, can’t say it’s thermal with certainty but possible load stress fracture where the glass has been packed.

 

Thermal stress fractures are not covered under warranty but load stress should be but needs to be proven.

 

If Thermal, then a solid argument to use is has the supplier advised on the risks of not using toughened/heat soaked glass? Did they give you the option? If no, it’s their responsibility tbh.

 

A decent supplier I’d expect them to take it on the chin “if” thermal and not advised of your options or load stress.

 

The position of the crack leads me to “suspect” load stress tbh, as that’s the area of the packer.

Hey thanks for your help - no thermal advice was given - will let you know what happens when we hear back.  They wanted vids and pics.  Hopefully we’ll get a reply soon.
