The DuraPlus system from DuraVent is designed to stay cool on the outside, provide a hot draft on the inside and boost stove efficiency, offering a fire-safe design that protects both the chimney and building. This Through-the-Wall Chimney Stove Vent Kit supports up to 40 ft. of DuraPlus chimney pipe (sold separately) and features the necessary items for a through-the-wall vertical chimney installation, including a chimney pipe with two insulating layers consisting of a ceramic blanket plus air space. The ceramic blanket insulation is held securely in position, eliminating hot spots common with loose-fill type insulations. In the event of a creosote fire, the compressible blanket insulation permits the chimney liner to expand outwardly in a radial direction. Designed for normal, continuous operation at 1000-degree F flue gas temperatures, DuraPlus is subjected to rigorous and stringent HT requirements of the UL standard, including one hour at 1400 degrees F, plus three 10-minute chimney fire tests at 2100 degrees F.

Rated 5.0 out of 5.0 by Great thru wall kit This is a well thought out kit with every piece needed to complete installation. The directions are clear and precise and the quality of the items in the kit are top notch. October 6, 2015
Rated 4.0 out of 5.0 by Helpful, but not perfect. The kit contained a number of necessary components for assembling the chimney. However, the short length of stove pipe will not be sufficient for many people trying to pass through today's highly insulated homes. Additionally, the fixed spacing wall mount brackets are not adjustable and therefore will be useless in many installations. Duravent sells much nicer adjustable brackets at substantial additional cost. Its upsetting to buy a kit that includes the 'budget' version of the components that won't work for many people. Furthermore, the finish of the T connector and the short length of triple-wall may or many not match the rest of the chimney, depending on the pipe you eventually purchase. Reaching M&G on the phone to ask questions is somewhat difficult and the rep on the phone was not very knowledgable about various install options. August 12, 2015
Rated 3.0 out of 5.0 by Careful This is why this is 50.00 bucks cheaper than everyone else. The Tee fitting is only stainless steel on the inside. All other important items are stainless steel with the rest of the kit. So in a year or two i will have a rusting tee fitting while everything else will still look nice. Hmmmmm forgot to mention this in the details part of the site. Careful September 29, 2015
Rated 5.0 out of 5.0 by Great product Purchased this thru the wall product (3) years ago for my camp. I did my home work a head of time so as to hopefully eliminate any problems when putting the hole thru the wall. Everything went together as advertised. The pipe is so well insulated that after having a fire in my stove for over a day there will still be snow on the thimble outside. Home Depot price also beat everybody else. September 27, 2015
Rated 4.0 out of 5.0 by Heartbeat of the Chimney I don't understand why the through the wall kit is exterior galvanized, while the pipe is all stainless. Just the way it is I guess. The through the wall thimble requires exact measurement and layout to get it correct. My installation was through masonry making it a little bit more difficult. Once the thimble is is, the rest is easy. I wonder about the long term weather tightness of the pipe going through the exterior wall plate. It is sealed with only caulk. A piece of circular flashing should be included with the kit. November 5, 2014
Rated 5.0 out of 5.0 by Great buy... back in 1999! We bought this whole kit, back in October of 1999, when we installed our Englander woodstove... it was easy to install, and it's easy to maintain... after 16 years of really great service (from both the Duravent chimney and the Englander woodstove!), we are looking at replacing it, only because we are redoing the whole woodstove area, and are thinking it would be prudent to do, even though, IF we weren't redoing the rest of it, we would've left it alone. Besides, we need a new arrestor! This is definitely a great product, and a great buy. You can do it! October 10, 2015

Rated 5.0 out of 5.0 by Easy to install Whole chimney went up in under 45 minutes, if you know what you're doing with the right tools then this kit is a walk in the park. October 29, 2015
