Insulation Around Wood Stove Pipe

You should never have insulation in contact with a wood stove flue pipe.

Insulation around wood stove pipe.

You worry for good reason. You cannot put fiberglass insulation around wood stove pipe or liners the liners are rated to 2100 deg with proper insulation and as you stated the fiberglass is less than that. I have a fireplace insert in my basement. Sprayed polyurethane foam will start to burn at about 650 degrees fahrenheit which is within the range of a wood stove s chimney temperature.

Rigid insulation increases the outside diameter of the liner pipe by 1 75. I want to insulate in the void above the woodburner so it will be about 2m above the actual fire. I packed some unfaced fiberglass insulation around the liner just under the plate at the top of the chimney. Compress the insulation around the rigid liner by hand until the two edges snap and lock together.

I have added a picture. Fireplaces emit a comforting glow during cold winter nights but if they are poorly designed they may take more heat out of your house than they put into it. Fire bug yes just in the damper area. Air traveling over the surface of the flue pipe may be required to keep it safe and cool.

Fiberglass insulation normally comes in the form of batts or blankets. Around the pipe for a woodburning stove. The fb grand manually specifically says to do this. The pipe comes out of the wall into the garage and up to the roof.

The area around the pipe will be an air heat leak i guess. Most code jurisdictions require the stove pipe be routed through a thimble to provide a safe distance from combustible materials. Available in 24 lengths. I was thinking of doing some better framing around it and maybe use rigid foam insulation but i read that building code requires a 2 gap around.

Piffin aug 06 2007 12 56am 3 look again at the parts a ceiling support has the cieling trim but also a shield that is a larger diameter than the pipe and stands 6 8 up into the insulation space of a typical flat cieling. Voids in a chimney flue liner to the full height of the flue is to use vermiculite chips can be bought for insulation purposes or as soil treatment check around for. If the point where your chimney passes through your wall or roof is badly insulated there is a lot of heat passing through that area and into the outdoors. This is why they sell special insulation for wood liners.

These are strips of the material that are cut to length for installation by being stapled to the ceiling of a basement or the floor of an attic and by being affixed around fittings such as pipe work and chimneys. I am reinsulating this wall and i need some advise on how to insulate this. Wood burning stoves.
