I witnessed fiberglass insulation crammed in the void between a gas insert and the masonry firebox. This doesn't appear safe to me. Any opinions out there? Any on-line resource recommendations for me to learn more about installation guidelines on these?

That looks pretty cheesy!

I can't give you an insight to your specific observation. But, as a mason I used to install metal pre-fab units called "Heatilators" which actually came with a blanket of fiberglass insulation to be installed around the unit. The intent was two-fold. 1. Insulation 2. To keep the masonry away from the metal to allow expansion and contraction.

Hi,

It's glass. It can't burn and it won't melt until it's melting temperature is reached, which is probably not likely with a gas fireplace insert. However, if it's insulation made with urea formaldehyde I have no idea what the ramifications of heating that stuff up are.
