We offer non-barrier tubing for use in potable water or heating applications using no cast iron components. We also provide radiant barrier type reflective insulation. We offer Pex tubing, for use in radiant floor heating and domestic water plumbing. Pex tubing is made from a cross linked (stabilized) high density polyethylene (HDPE) polymer. The HDPE is melted and continuously extruded into tube. PEX tubing is flexible, resistant to scale and chlorine, doesn't corrode or develop pinholes, is faster to install than metal or rigid plastic, and has fewer connections and fittings.
