Insulation For Ventinox Liner
The traditional form of insulation for Ventinox Liners is TherMix. TherMix is an excellent insulator - you'll find it featured on our Insulation Page. Longtime Ventinox users may also be aware that Ventinox offers a blanket-type insulation called ProFoil. The people at Underwriters Laboratories and Ventinox have thoroughly tested HomeSaver's 1/4" Foil-Face FlexWrap and found it to be a proven substitute for ProFoil. Therefore, if you choose to insulate your Ventinox Liner with ceramic blanket, simply use HomeSaver 1/4" Foil-Face FlexWrap. Always insulate in accordance with manufacturer's instructions.

Here's how to block off the damper frame area when you're making a connection from a stove or insert to only the first flue tile area of a chimney.
This easy-to-use Connector Sealing Kit allows installation from below the damp frame. It includes an insulation "gasket" and two precut galvanized sheet metal sections that adjust to fit snuggly around your length of HiFlex 321 oval relining pipe. All necessary hardware, instructions and crossbars to suspend the metal sections from the damper frame are included.
This round insert boot is for inserts with round or rectangular openings. Its base inside dimension is 8 1/2" x 16", the outside dimension is 10 1/4" x 18" and it's 4 3/8" high. It's made of heavy steel and comes in 6" or 8" diameters with a 20" angle. Attach to insert by drilling holes into the insert and bolting it down, or tapping/screwing to the insert.
Ventinox FasClamp Fastening System allows all Ventinox components to fasten to Ventinox Liner without pop rivets. An internal draw band system does the job. All it takes to attach components to the liner is a screwdriver or a 5/16" nut driver.
The FasClamp System means you can eliminate drilling your liner. And since pop rivets in 321-alloy stainless steel or AL 29-4C stainless alloy are not available, FasClamp does away with the need to use pop rivets of an entirely different alloy to fasten Ventinox components and liner.
The FasClamp System is available for all Ventinox components. Ventinox recommends you use the coupler to join two pieces of HiFlex, VFT, or VG Liner. It's available in 321, in AL 29-4C, or 316 Ti. On all components, the draw band itself is 304-alloy stainless. Consult price list below.
Thread a rope through the cone's end and screw it into the corrugations of the liner. Pulls the liner easily down the flue. 304-alloy.
45 DEGREE SECTIONED, ADJUSTABLE and 90 DEGREE ELBOWS available in 6" and 8" diameters.

Top-Mounting Hardware Assembled On Ventinox
Here's the Ventinox rain cap and top plate assembled on a piece of Ventinox Liner. Notice how efficiently the components mate together.
The Ventinox rain cap features an inverted cone design. This allows creosote condensation to drip back into the flue to prevent chimney staining. Made of 304-alloy stainless and features the FasClamp Fastening System. Rain cap also serves as storm collar and top clamp.
When you choose not to use a Ventinox rain cap, you'll need to use the storm collar with the FasClamp Fastening System. Notice how the storm collar is flared to go-right over the outside of the top plate. The storm collar is made of 304-alloy stainless and is intended for use on HiFlex, VFT, and VG installations.
When using the Ventinox rain cap or storm collar use one of these top plates. It allows the rain cap or storm collar to fit properly. Available with outside dimensions of 13" x 13" in 3" - 8" diameters and 18" x 18" in 9" -12" diameters.
