The Retro Zone System
Retrofitting an existing metal roof with heat panels couldn’t be easier with the Retro Panel’s simple design. New heated panels are layed on top of the old metal roof. Colors can be matched to your existing roof. The aluminum alloy panel surrounds the available heat source; the top, bottom and sides are in direct contact with the heat source at all times.
Material Selection
UNA-CLAD Kynar 500 Painted Aluminum, 20 oz. Copper, Core-Ten and other specialty options are available.
Panel Color Options
The siliconized-modified polyester coatings on T-Zone Systems carry a 30-year warranty. Virtually any custom color is possible. For a true color representation, please call for actual metal sample(s).

Compatible Heating Cables
Commercial Grade-Self Regulating Heat Cable (5, 8 or 10 Watt per foot in 100-130 VAC or 208-277 VAC) or 3/8” PEX Hydronic Radiant Tubing.
*RHT Radiant PEX pipe is a composite PEX-b pipe created with the silane cross-linking method (similar to Zurn Pex and Watts RadiantPEX). It fully meets today's strict ASTM F 876, 877 and NSF 14/61 standards for PEX tubing and has been certified for use w/potable water. RHT PEX is produced with a strong Oxygen-Barrier and can be used interchangeably for either heating or drinking water supply lines.
