6. About This Program
With so many facets to the building process and unlimited amount
of systems, products and techniques to offer your clients, it can be
difficult to know which ones have the highest quality, the broadest
product and design offerings and will be there to educate, service
and support you.
The concept of electric floor warming is not necessarily new to the
building industry, but advancements in efficiencies and
technologies have led to new and innovated products load with
more features and benefits to offer consumers.
This two-hour class is designed for construction and design
professionals to gain a better understanding of electric floor
warming as an reputable and ideal system to enhance the lives of
consumers through wellness, safety and comfort.

82. Calculations Above Floor
1. Measure the length of each joist bay that is not
underneath cabinets, closets or spaces that should
not be heated
2. Check the spacing between joists
3. Select one UnderFloor mat per joist bay
4. If space is in-between 2 sizes, select the shorter
length

83. Calculations Under Floor
1. Measure the length of each joist bay that is not
underneath cabinets, closets or spaces that should
not be heated
2. Check the spacing between joists
3. Select one UnderFloor mat per joist bay
4. If space is in-between 2 sizes, select the shorter
length

129. Look for The Standards

130. Products have been tested to the American Standard Test Method: ASTM
C627, a standard test method for evaluating ceramic floor tile installations
systems using the Robinson-Type Floor Tester.
This test was performed by the Tile Council of America for installation above
a concrete slab and above a framed floor.
This ASTM testing resulted in a rating of “Moderate Commercial” for normal
(non-vehicular) commercial and light institutional use. This would exceed all
(non-vehicular) residential use as well.

find it. No need to replace the floor!
