I want to insulate in the void above the woodburner so it will be about 2m above the actual fire.
Insulation around wood stove pipe.
The area around the pipe will be an air heat leak i guess.
Rigid insulation increases the outside diameter of the liner pipe by 1 75.
At the top i have a plate covering the flue with a cap on top.
The stove sits in front of the fireplace and the piping runs through the damper plate opening and up the length of the chimney about 20 feet.
You should never have insulation in contact with a wood stove flue pipe.
You worry for good reason.
The fb grand manually specifically says to do this.
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 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.
Sprayed polyurethane foam will start to burn at about 650 degrees fahrenheit which is within the range of a wood stove s chimney temperature.
The only insulation that should be touching that flue pipe is something that s rated for high temperatures like mineral wool and even then only in accordance to the manufacturer s instructions.
I packed some unfaced fiberglass insulation around the liner just under the plate at the top of the chimney.
Available in 24 lengths.
I have a fireplace insert in my basement.
This is why they sell special insulation for wood liners.
Fire bug yes just in the damper area.
Around the pipe for a woodburning stove.
Compress the insulation around the rigid liner by hand until the two edges snap and lock together.
Fiberglass insulation normally comes in the form of batts or blankets.
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.
Air traveling over the surface of the flue pipe may be required to keep it safe and cool.
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.
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.
Most code jurisdictions require the stove pipe be routed through a thimble to provide a safe distance from combustible materials.
Wood burning stoves.
The pipe comes out of the wall into the garage and up to the roof.
I have added a picture.
