System Description:
Levelrock Brand Floor Underlayment RH (Radiant Heat) is a fast-applying gypsum cement designed by USG for use in both residential and commercial construction. Levelrock Brand Floor Underlayment RH (Radiant Heat) is specifically formulated for electrical and hot water radiant heat floor installations. It is formulated to provide compressive strengths up to 3200 psi at 3/4-inch minimum thickness up to 3-inch maximum thickness. The tough compressive and surface strengths of Levelrock Brand Floor underlayment RH (Radiant Heat) allows for long-term resistance to trade activity typical of single-family home and light commercial construction. It accepts virtually all types of floor coverings such as ceramic tile, carpeting, and wood. The non-shrinking nature of Levelrock Brand Floor Underlayment RH (Radiant Heat) locks tubing in place, prevents noise and tube chafing, and its special formulation prevents the high temperature associated with radiant heat floors from breaking down the floor matrix.

Product Description:
USG poured gypsum underlayment products are mixed with sand and water to yield a lightweight slurry. Most radiant heat jobs will be poured at 1-1/2 inch thickness to cover the pipes. A 1-1/2 inch thickness gypsum underlayment weighs approximately 14.4 pounds per square foot and has a density of only 115 pounds per cubic foot.

System Benefits:
USG poured gypsum floor underlayment systems provide an economical way to achieve lightweight, fire-resistant, sound-rated floors in residential and light commercial construction. Typical applications are less labor intensive than many other types of construction and provide high fire ratings characteristic of gypsum systems. Higher compressive strengths minimize damage to floors from trades.
