Replacement stove glass

[bmp01]

Chaps,

 

Well, I've darn gone and busted the glass in the stove..... lack of maintenance I reckon, not changed the sealing rope in 15 years and now I'm gonna pay for it.

 

So, it's a Stovax Huntingdon 35, glass is 390 wide by 305 tall, with quite a pronounced curve to the top edge. 

-Direct from manufacturer is 80 pounds plus delivery and is on back order.

-Supplied by Calfire, supposed to be Schott Robax material, is 40 pounds.

 

Sounds like a no brainer until you look at glass thickness,  Stovax is 5mm thick Schott Robax 4mm.

 

 

Thoughts, anyone had direct experience of replacing stove glass, where to buy etc. Also is it worth polishing the edges to get rid of 'crack here' nasty finishes?

 

Thanks,

Hi, Just bought a spare Schott Robax glass by Calfire for my Morso on Ebay, a bit smaller than yours but that's what I last fitted when I broke mine some years ago and It's been fine....I doubt they'd sell any if they couldn't be fitted.

 

The last time mine broke [ carelessness ] I made a temporary  replacement with a piece of sheet steel  so I could still use the fire...also handy to have lying around if needed, cheers.

Nice one, thanks for that. 

The steel sheet thing,  yeah, i had that thought - comforting to realise I could get it working if need be.

when our glass fell out we just took the bits out, put the spark guard from upstairs in front and carried out without the glass. The stove then just becomes a slightly more efficient open fire but it stillworks without the need to make a temporary replacement

4mm is the industry standard,  make sure you change the rope under the glass,  do NOT overtighten the fixing screws,  the glass needs to be able to expand a shade when hot.

All good info. I do wonder why Stovax went for 5mm though.  As stated 5mm is not something people stock.

I agree the glass needs to be able to move in the surround but here's something to ponder : this stove glass has a very low expansion compared to normal glass which already has a low expansion - if it's mounted in a cast iron (or steel) door which has a massive expansion rate in comparison  to normal glass what happens when the stove heats up ?

I'd wager the frame expands more than the glass .... 

Not that it makes any difference,  still got to let the glass move.  I plan to support the weight of the glass on thick glass fibre pads (2 off), new glass fibre seal and use the screw clamps just to stop the glass from wobbling about - little or no pressure. Currently the glass weight is taken by clamping the glass tight enough to stop it sliding down....

Most stove manufacturers use a flat self adhesive rope to fit between the door and the glass for exactly this reason.    Most stove shops should stock it, usually 10mm x 2mm,  trim to suit if needed.  Not aware of what Stovax use as I am not a dealer for them,
