What Poured Finish Flooring to Use Over a Thermal Mass Passive Solar Concrete Floor Slab
The question-and-answer article below paraphrases, quotes-from, updates, and comments an original article from Solar Age Magazine and written by Steven Bliss.
What Poured Finish Flooring Products are Available to Use Over a Passive Solar Thermal Mass Concrete Floor Slab?
Question:I plan to build a passive solar home with poured acrylic floors over a thermal mass concrete slab.
I understand tha these finishes can be installed for as little as $2 a square foot [in the 1980's].
How will they affect the solar performance of our passive thermal mass concrete floor slab?
- Gerald Griffith, Columbia PA
Our photograph (above left) shows a modest (limited sunlight) passive solar interior floor, constructed over a poured concrete slab in a Minnesota Cabin on Lake Superior. The designers intended to use a radiant-heated insulated concrete floor slab, but unfortunately the builder installed the radiant tubing improperly and the heat was not usable. (See RADIANT HEAT FLOOR MISTAKES). The insulated concrete floor continues to function as a limited passive solar slab, offering thermal mass that steadies building temperatures even in very cold Minnesota weather.
In the 1980's poured acrylic flooring products were difficult to find but available. Poured acrylic or poured epoxy finish flooring products come in two parts: an acrylic (or epoxy) matrix and a catalyst (hardener).
You can vary the pattern and color of the poured finish floor covering by adding colorants and chips to the material.
The abilities of the surface to absorb and conduct heat both affect how much heat enters the thermal mass passive solar floor slab. Because the acrylic (or epoxy) finish flooring bonds chemically to the concrete floor, heat should flow into the slab better than it would through adhesive-bonded resilient flooring and better than it does through adhesive-bonded ceramic tiles in our photograph of the Minnesota floor above.
The darker the color of your pour-on finish flooring, the more heat will be asbsorbed. Light flooring materials absorb less solar radiation (heat) and are thus less efficient (as much as 40 percent less for pastel colors).
Examples of Pour-on Finishes for Thermal Mass Concrete Slabs

"Passive Solar Home Design", U.S. Department of Energy, describes using a home's windows, walls, and floors to collect and store solar energy for winter heating and also rejecting solar heat in warm weather.
"Solar Water Heaters", U.S. Department of Energy article on solar domestic water heaters to generate domestic hot water in buildings, explains how solar water heaters work. Solar heat for swimming pools is also discussed.
"Heat-Transfer Fluids for Solar Water Heating Systems", U.S. DOE, describes the types of fluids selected to transfer heat between the solar collector and the hot water in storage tanks in a building. These include air, water, water with glycol antifreeze mixtures (needed when using solar hot water systems in freezing climates), hydrocarbon oils, and refrigerants or silicones for heat transfer.
"Solar Water Heating System Freeze Protection", U.S. DOE,using antifreeze mixture in solar water heaters (or other freeze-resistant heat transfer fluids), as well as piping to permit draining the solar collector and piping system.
"Solar Air Heating" U.S. DOE also referred to as "Ventilation Preheating" in which solar systems use air for absorbing and transferring solar energy or heat to a building
"Solar Liquid Heating" U.S. DOE, systems using liquid (typically water) in flat plate solar collectors to collect solar energy in the form of heat for transfer into a building for space heating or hot water heating. The term "solar liquid" is used for accuracy, rather than "solar water" because the water may contain an antifreeze or other chemicals.
