Insulation for Relining Pipe
Products available for insulating include the following:
The Importance Of Proper Insulation
All ceramic blankets are not alike. Even brands with similar factory ratings have shown dramatically different insulating characteristics when put to a heat test in a "real world" chimney. this is why it's so important that genuine HomeSaver Foil-Face FlexWrap be used with HomeSaver.
Additionally, please understand that to create a HomeSaver relining job that meets the UL Listing Standards, you must use only HomeSaver Foil-Face Flex-Wrap, InsulationMix, or TherMix.
Two Reasons To Insulate:
When you use genuine HomeSaver Foil-Face FlexWrap, you're getting the best dollar-for-dollar insulating value on the market. Foil-Face FlexWrap is one of HomeSaver's recommended insulations for all their flex liners. HomeSaver Foil-Face FlexWrap is also a suitable insulator for Ventinox VG, VFT, and HiFlex Liners, 1/4" only.
Insulation is a necessary part of a UL/ULC Listed HomeSaver solid fuel relining installation. Always install it according to instructions. Foil-Face FlexWrap is truely a great insulator. It consists of special ceramic fibers that resist separation, making it perfect for installations with bends and offsets. When installed, it also helps to center your liner porperly in the chimney.
HomeSaver Foil-Face FlexWrap comes in two thicknesses, 1/4" and 1/2". The 1/4" FlexWrap lofts to a working thickness of about 1/2". The 1/2" FlexWrap lofts to a working thickness of about 3/4". HomeSaver 1/4" Foil-Face FlexWrap is available in 25' rolls in 24", 30", and 48" widths. 1/2" Foil-Face FlexWrap comes in 24" and 48" widths, and in custom widths in our insulation kits.
HomeSaver's special ceramic blanket is covered with a tough aluminum foil that's 2 mil for 1/4" or 3 mil thick for 1/2". The foil adds insulating value and makes FlexWrap easy to work with and easy to cover with HomeSaver ArmorMesh.
To install FlexWrap, simply wrap it lengthwise on your pipe and secure it with an adhesive. Seal the seams with foil tape and cover it with HomeSaver ArmorMesh Insulation Cover - you'll find all of these products below. And you will also learn just how and when to use 1/4" or 1/2" thickness of Foil-Face FlexWrap, depending on the clearances on a particular job. And please, read everything presented for you here and on down. You'll learn about insulation and how it relates to the UL/ULC Listing. See chart to determine which width to use with which HomeSaver liner. View Insulation Trim Chart featured at bottom of this page.
Though they are not UL Listed for use with any of our chimney liners, we also offer two non-foil-face versions of FlexWrap.
You can use Non-Foil-Face FlexWrap for sealing between the shroud of an insert and fireplace facing. Also great for replacing the insulation seal between frames of glass doors and fireplace facing. It's also a good all-around insulator that's often used in non-relining situations where large volumes of insualtion are needed.
*You'll find lots of uses for Non-Foil-Face FlexWrap, but never leave any blanket exposed to a living area as the fibrous dust may be harmful if inhaled.
Remember: Non-Foil-Face FlexWrap is not UL Listed for use with any relining products.
We put our Foil-Face FlexWrap insulation in a kit so you can get everything you need for a typical relining job. When using HomeSaver Pro or UltraPro insulation kits with their matching relining kit, you'll find the insulation is cut perfectly for the liner size you order. The liner kits come in 25', 30', and 35' lengths which means you will not have to measure and cut the insulation yourself. (There will be just a slight amount of trimming needed when using HomeSaver RoundFlex).
HomeSaver Pro and UltraPro insulation kits come with 1/2" insulation. That means you only have to use a single wrap of insulation on the pipe, not the two wraps required with 1/4" insulation. Since one wrap of 1/2" gives a smaller outside diameter on the finished product than two wraps of 1/4", you'll have even more clearance for getting HomeSaver Pro down the flue. Naturally HomeSaver Pro and UltraPro are UL/ULC Listed for one wrap of 1/2" insulation.
Note: All kits include Foil-Face FlexWrap, ArmorMesh, aluminum tape, 1 Make-A-Clamp kit and 1 3M spray adhesive.
Now with just two item numbers (one for the relining kit and one for the insulation kit) it's possible to get everything you need for a reline, including insulation, perfectly sized for the job. Consult our sizing charts shown at bottom of this page.
Required as part of a HomeSaver UL Listed installation, this tough 304 stainless woven wire mesh wraps, holds, and protects HomeSaver Foil-Face FlexWrap in the chimney. ArmorMesh makes FlexWrap highly resistant to snagging or tearing during installation, and its presence guarantees that FlexWrap will stay in place, around the pipe, for years to come.
The picture in the upper left corner shows ArmorMesh as it arrives - in a 25' roll. As you can see, the "roll" is really a "tube shape." Simply open the ArmorMesh and slip it over your FlexWrap (upper right photo - for simplicity, pretend this short piece of HomeSaver is a full liner length).
As the photo at lower left shows, clamp one end of your ArmorMesh to the pipe using our unique Make-A-Clamp System shown below. Then take the loose end of the ArmorMesh and pull, Presto. the ArmorMesh immediately tightens to fit snugly around your insulation. Then add the final clamp, as shown in lower right photo.
ArmorMesh comes in three sizes: small, large, and extra-large. Consult our handy sizing chart below.
Attaching ArmorMesh to HomeSaver Chimney Liners requires different-sized, stainless, radiator-type hose clamps. The fantastic Make-A-Clamp system gives you any length clamp you need. A close look at the photo on the box shows just how the Make-A-Clamp System works. Basically, you have a roll of stainless steel strapping and a series of male and female clamp ends. These clamp ends hook right onto your strapping after you cut it to whatever size you need. Making clamps - from huge to small - is a breeze. Mini-Kits, Maxi-Kits, and boxes of 10 extra fasteners are available.
...for a total HomeSaver installation, HomeSaver InsulationMix is a UL Listed 1777 Zero Clearance insulator for HomeSaver Relining Pipe. Also use for ULC S635-00 standard. This includes UltraPro, Pro, RoundFlex, RectangleFlex, and OvalFlex. HomeSaver InsulationMix may also be used for Dial-A-Flex and FireplaceFlex. A big plus for HomeSaver InsulationMix is its bag-to-bag weight consistency. You can depend on your bag calculations being right every time. HOMESAVER INSULATIONMIX MIXING AND INSTALLATION INSTRUCTIONS
TherMix is a UL Listed 1777 Zero Clearance insulator for HomeSaver Relining Pipe. It's also recommended with Ventinox VG, VFT, an HiFlex Liners.
PREPARATION IS THE SAME FOR INSULATIONMIX AND THERMIX
HomeSaver InsulationMix is available in 45 lb. bags and fills 2.4-3 cubic feet. They are easy to work with, poor easily (they have the consistency of damp potting soil), and contain no asbestos. To figure how many cubic feet you need on any given job, you need two things:
Subtract the latter (2) from the former (1) and you've got the volume of insulation you'll need. Here are the mathematical formulas:
Hold it! Remember that TherMix bag holds 2.4-3 cubic feet and HomeSaver InsulationMix bag holds 2.5 cubic feet, so be sure to divide your final figure by either 2.4 or 2.5 to determine how many bags you'll need for the job.
Please follow all instructions on the product bags, paying particular attention to requirements concerning mixing, curing, drying, and chimney sizing. Wear a respirator, goggles, and adequate skin protection when working with HomeSaver InsulationMix or TherMix.
Note: HomeSaver liners are UL Listed with both mixes. Ventinox is only listed with TherMix.
