The glass on a wood burning or multifuel stove is heat resistant, highly polished and heat stable, but it isn’t toughened. Therefore, it should be expected that this will need replacing at some point in a stove’s life. Cracked, shattered, or crazed glass can be caused by a few common factors:
- Closing the door on a protruding log
- A rogue fireside tool
- Over-firing causing the door to warp, putting stress on the glass
- Over-tightening the clips that hold the glass in place, which will expand with heat
- Uneven casting
- Natural heat expansion
- Acidity in the fuel being used

Check out our helpful guide to replace your stove’s glass in a few simple steps.
- Allow the burner to cool fully before attempting to do anything.
- If you can, remove the door and lay it on a flat surface. It’s not the end of the world if you are unable to do this, it just makes life easier.
- Loosen or unscrew the retaining clips that hold the glass in place. If these have seized up over time, use some WD40 or gently tap the screws.
- Remove the old glass wearing gloves to avoid injuring yourself on sharp edges.
This is an ideal time to also replace your rope seals if they are frayed, hardened or loose. If you need help with this, take a look at our installation guide on how to easily replace your rope seals.
- Clean the stove door removing any loose or flaking material.
- Place your new glass into the door making sure it is central, has room to expand and creates a seal with the stove rope.
- It is IMPORTANT to reattach the retaining clips removed in step 3, but make sure you don’t over-tighten them. You want these to be finger tight only. As the stove heats up, all metal fixings including the retaining screws will expand, putting pressure onto the glass. Too tight and they will cause the glass to crack.
- Replace the stove door back onto its hinges.
