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.

Fireplace insert replacement glass
I called and spoke to a young lady that walked me through the order placement process. My glass came in quickly fit perfect very well pleased. I will definitely recommend you to my friends.
Thank you!!! What great response!!! I appreciate the quickness and the service of your company!!!
Glass had to be resized to meet order once. Customer service was amazing. Unfortunately the glass was not. Even with the resizing and additional information provided the glass failed to meet the specifications required. Although the company was amazing to work with, I will have to go somewhere else with my business.
This was the lowest price for glass
As I responded above, all went well and I appreciate being able to purchase the replacement glass for my gas fireplace insert at a reasonable cost. Thanks.
I received my shipment of the Cottesmore Electric Coal Basket this morning. I am very pleased with the basket and the way it operates. The heater is very quiet and the flickering flame effect is very attractive. I had planned to plug the unit into the electrical outlet on the right side of my fireplace. The electric cord is not long enough to reach that outlet since the cord comes off the left side of the unit. I will have to work something else out. I was very happy and surprised to receive the basket this soon. Thank you for such excellent service. Its been a real pleasure doing business with your company.
