ZMesh the Great!

by Steve Bench

When people associated with the radiant heating and radiant snow melting industry use the words “ZMesh”, “Golden Mesh”, “Z Mesh”, or just plain “Mesh” usually they are referring to a durable line of low voltage electric products made by Heatizon Systems and used for Radiant Roof Snow Melt and De-icing, Radiant Floor Warming and Radiant Heating.

Designed to be installed on and under sub-floors and on sub-roofs, ZMesh provides a nice uniform heat and it is plenty robust to satisfy the demands of discriminating radiant heat, radiant roof snow melting and de-icing, and radiant floor warming customers. In addition, gold colored, ZMesh delivers unparallel performance and is backed by an industry leading twenty-five (25) year warranty.

What about the nails, screws, and/or staples used to attach certain flooring and roofing materials? No need to worry about nailing, screwing or stapling through ZMesh as long as the nail, screw, or staple does not come into contact with anything else electronically conductive. In other words, ZMesh should never be installed over or under metal roof decking, valley metal, metal flashing, etc. or metal roofing materials such as steel or copper but its durable sister Tuff Cable may be installed over and under such products. ZMesh can be installed, however, under all non-conductive roof shingles and nearly all floor coverings.

Unlike its line voltage and hydronic radiant heating, radiant in-floor and under floor warming and radiant roof snow melt and de-icing competitors, ZMesh is very simple and easy to repair in the event it gets cut or damaged. Repairing ZMesh requires a customized copper splice plate and a bit of solider. No one else in the radiant heating, radiant floor warming and radiant roof snow melt and de-icing business can honestly make that claim.

How much floor build-up does ZMesh require? Since ZMesh is only 1/16th of an inch thick and does not require a bed of light weight concrete or other cementous material to draw the heat away from it the answer to this question is “very little”! As a result using ZMesh avoids the expense of a cementious mud bed, the cost of the extra structural integrity necessary to support the weight of the concrete and the challenges created by the need for the additional framing required by radiant high or line voltage and radiant hydronic or hot water alternatives. Once again, ZMesh requires little or no floor build-up.

For radiant in-floor and under floor warming and radiant heating applications ZMesh may be installed in the floor (on top of the sub-floor and below the floor covering) or under the floor between the joist space. As a matter of fact, Heatizon Systems was one of the pioneers of retrofitting its products into the joist space of existing structures.

ZMesh is a cut to length in the field product rather than a fixed length product like most all of its UL listed radiant line or high voltage competitors. The ability to vary the length of the ZMesh enables the installer to adjust the radiant in-floor heating, radiant roof snow melt and de-icing or radiant floor warming system to fit the area rather than requiring that the area to adjust to the radiant in-floor heating, radiant roof snow melting and de-icing or floor warming system.

Available in lengths that extend from 50 feet to 400 feet and widths of 9 and 12 inches, ZMesh is plenty versatile to satisfy the needs of most projects. In addition ZMesh has the ability to deliver up to 11.5 watts or over 39 Btu’s per linear foot so it is plenty robust to heat entire spaces, warm spacious floors, and manage the risks of ice dam related roof damage.

Heatizon Systems cares about its customers and their property as a result all of its products have been tested to UL Standards and has earned the privledge of being listed by ETL, an internationally recognized testing laboratory approved by the United States Environmental Protection Agency.

Heatizon Systems products are proudly manufactured in the United States of America and may be purchased by fine distributors located across North America.

ZMesh

ZMesh is a 9 or 12 inch wide bronze mesh heating element used for in-floor radiant space heating, radiant floor warming, and roof deicing. Zmesh can be installed under non-metallic shingles and single ply membrane and under most floor coverings including carpet, hardwood, laminates, tile, slate, marble, and linoleum/vinyl. ZMesh’s durability is also perfect for your remodeling/retrofit applications.

ZMesh 12” is and excellent product for heating the entire home or for simply heating your floors. ZMesh 12” – wide, bronze mesh is similar to screen door material and comes in 50 to 350 foot rolls (in 50 ft. increments). ZMesh is a premier product because of its extremely low profile and ability to heat evenly. No other heating products can match its characteristic. Because ZMesh is so thin, it will not affect floor buildup, weight loads or flooring choices. ZMesh can be secured to wood sub floors with staples or nails and to concrete with glue or tape. ZMesh can even be installed underneath the cement board when used to heat tile. No additional mortar or thin set is needed to cover the heating system because it is sandwiched in between the sub floor and cement board. Because Heatizon Systems’s ZMesh products operate under 32 volts, it is possible to safely put your hand directly on the ZMesh during operation.

ZMesh 9” is used for melting ice and snow under non-conductive shingles or surface asphalt, shake or slate shingle roofs and is ideal for new construction or remodeling. It is only 1/16” thick. Our ZMesh 9” wide element is used for radiant roof deicing and can be nailed or stapled through, making its installation easier than other systems. Costly and disruptive roof ice buildups are eliminated with the use of this unique and low profile roof heating element. The ZMesh is installed underneath the shingles, so its appearance does not compromise the aesthetics of any structure nor is it exposed to weathering or corrosion. The 9” ZMesh is spaced at 2” and rolled out over the area to be heated. Depending on the roofing project, anywhere from 4 to 12 runs of ZMesh may be needed from the roof’s edge up. ZMesh can be installed on the entire roof, it is desired to eliminate snow or ice buildup. A great advantage of our roof deicing system is its versatility. You can roll out the ZMesh into any pattern to heat any desired area. ZMesh 9” is the only under roof heating product that is ETL listed.

The ZMesh 9” or 12” is listed to U.L. Standards and the product carries the ETL label. ZMesh has an industry leading 25 year warranty, and is long lasting with its “Warming America’s Cold Spots Since 1979” track record.
