FAQs for Heatizon’s Systems & Applications

Our FAQs have been complied from our years in the radiant heating industry. Feel free to email us, with any questions you might have about our systems, applications or product lines.

Roof Deicing & Heat Tracing

GutterMelt SR Cables are self regulating and do not over heat.  The heat output of these cables increase as the surrounding temperature decreases and output decreases as surrounding temperatures increase.  GutterMelt is perfectly fine to use with plastic downspouts due to these self regulating heating characteristics.

Our gutter heating cables (GutterMelt) are the ideal solutions for preventing dangerous and damaging snow and ice forming.  It is recommended that gutter melting cables be used in conjunction with our roof systems.  Our cable systems are also activated by automatic sensors that sit in the gutter.  And conserve energy by only turning on when necessary.

The Tuff Cable Invizimelt/Heat Sink kits for roof deicing are designed to be installed under metal roof, valley metal and flashing.  Tuff Cable must always be embedded completely in an Invizimelt/Heat Sink system regardless of which roof covering is going over it.

Tuff Cable is a resistance heating wire that is very durable, 10 gauge coated copper cable that is chemical resistant and comes with footage marks on the wire.  The Tuff Cable has been engineered to work as a low-voltage system.

ZMesh was first used over 28 years ago.  Since 1979 the 9” ZMesh systems have been sold worldwide and are still in operation.

ZMesh is ETL listed for the United States and Canada and conforms to UL Standard 1588.  Heatizon Systems Roof Snow and Ice Melt products are the only products available today that are listed for under-roof applications.

ZMesh comes with an industry leading, 25-year manufacturer’s warranty.

It is not recommended that you use ZMesh underneath a metal roof. We recommended that Tuff Cable in Invizimelt/Heat Sink be used instead.

Roof deicing systems can be activated with an aerial-mounted moisture and temperature sensor, temperature sensor, gutter –mounted switch, or 12 hour manual timer.  With the aerial-mounted moisture and temperature sensor with automatically turn on when the temperature is below 38 degrees and there is moisture on the sensor.

The largest 9” ZMesh system (zone) will cover approximately 425 square feet.  Multiple zones are sometimes required for larger projects.

9” ZMesh is sandwiched in between two layers of ice and water shield and stapled to the roof decking.  Shingles are then secured with nails directly on top.  Nails can pierce the ZMesh as long as the nails do not come in contact with any other metal objects.  The ZMesh comes in 9” wide rolls and is rolled out over the area to be heated.  Heating at least 6” above the roof eaves is recommended.

No, because it is “paper thin” no roof buildup or construction alteration is required.  ZMesh is 1/32” thick and 1/6” on the fold back.  This is not the case with other types of radiant heat systems.

ZMesh is a 9” or 12” wide durable bronze heating element that resembles screen door material.  It is used to melt ice and snow off roofs and is listed to be installed under shingles to UL standard 1588.

ZMesh is installed under shingles for several reasons.  Heatizon offers a long term solution to winter roof problems and we believe in do the project once and do it right.  ZMesh is protected when it is installed under the shingles and in most cases will outlast the roofing above. Thinking long term we offer an invisible solution as well as the longevity of a system that will perform for the long term so the customer will never have to worry again about winter roof problems. To install ZMesh existing shingles will need to be removed by a roofing contractor so it can be installed on the sub-roof with a layer of ice and water shield over the top of the system before shingles are installed back over it.

Yes, ZMesh can be installed over any membrane and covered with an additional membrane.

Since 1979, Tuff Cable systems have been sold worldwide and are still in operation, worry free.
