Stove Bright M230™ is an easy-to-use sealant for maintenance and installation of wood stove gasket, direct vent appliances such as pellet stoves, and gas-burning systems. This high heat sealant can also be used to seal a metal flue for wood and coal burning stoves. This sealant resists peak temperatures of around 1100°F but is designed for use with a continuous operating temperature of around 900°F. Create a safe fireplace seal and be sure to only use the best high heat sealant available - the M230. Black in color. Will dry as a charcoal finish available in a 10.3oz caulking tube for easy installation.
Please note: M230 Be Cured At 200°F For Approximately 1-1/2 Hours. This product contains 2-Dimethylaminoethanol and can cause nose and throat irritation. It may be harmful if absorbed through the skin. Always wear protective glasses, gloves, and clothing when applying, and wash thoroughly after handling.

The only sealant that will stay flexible are silicone based sealants and this specific product is not silicone based.06/12/2016
Thank you for visiting CJ's, unfortunately this item will not work. The high temp is only useful for stoves and direct vent seals in the pipe. Roof flashings need just regular silicone.
I hope this was helpful. Thank You29/05/2016

It is a good idea to use some type of fiber glass gasket to protect the glass from thermal expansion.
You can find all both gasket and cement by viewing the below link.

Ron helped me out very well on the phone (assistance with measuring). I was impressed with his follow-up too.
Wish I would have found you sooner
Thanks for the help - I had stalled for years in doing this without a local company - this on-line process worked very well - clear directions and followup to questions and good suggestions. Thanks!
Finally got to use these doors
I got my fireplace doors, and I just wanted to say thanks! They look fantastic, work perfectly, so simple to install. I couldn't be any happier! Thanks so much for all your help with getting the right doors for my particular fireplace. We all gathered around the fireplace this afternoon and enjoyed the fire and the doors!!
Thank you for the quick reply. I was successful installing my fireplace door this morning by adding a couple of washers between the bracket and bolt/screw supplied. I really am thrilled with the quality, craftsmanship, and ease of installation. Maybe this tip will help others if they find themselves in a similar situation.
I really enjoyed working with you! Your attention to detail and follow up were beyond expectation.
