Uponor Wirsbo offers contractors more choices with Quik Trak(R), its new wood panel system designed for fast, easy and cost-effective installations with special advantages for remodeling and retrofit projects. Quik Trak is an aluminum heat transfer sheet attached to 7" x 48" or 10" x 48" wood panels that are only 1/2" thick. Once the panels are in place, Wirsbo hePEX(TM) plus tubing is snapped into a groove running down the center of the panel. The shallow 1/2" profile means it can be placed over almost any floor with little need to raise door heights, molding or wood trim. Uponor Wirsbo. Circle 4.
