PEX-Al-PEX

The new Alumicor® PEX-Al-PEX tubing offers the benefits of cross-linked polyethylene tubing plus it holds its shape when bent. A layer of aluminum is sandwiched between two layers of PEX that not only gives it an easy-to-handle, malleable characteristic, it also improves heat transfer and acts as an oxygen barrier, helping to protect the boiler and all other nonferrous system components from corrosion.  Zurn Industries www.zurn.com

Gypsum Underlayment

Therma-Floor® gypsum underlayment

Therma-Floor® is a gypsum underlayment designed to pour over hot water tubes or electric heating cables. It acts as the thermal mass for any radiant floor system. Therma-Floor encases the tubes or cables in crack-resistant, noncombustible gypsum. It resists breakdown to 150 degrees F and, because it's poured only 1 1/4 inches thick, the heating system is more responsive and more comfortable.  Maxxon Corp.  www.maxxoncorporation.com
