LP Legacy® Sub-Flooring
Description
• Single-layer sub-ooring designed for residential and light
commercial construction, including manufactured and
modular home applications.
• Features a self-spacing tongue and groove system that is
specially engineered to t together with ease.
• Features panel end RainChannel
®
notches that allow
trapped water to drain from oor joists.
Basic Uses
• When fastened over appropriate framing, panels provide
a structural oor deck that serves as a suitable surface
for additional framing or underlayment. When properly
installed, panels will provide a surface that is appropriate
for the direct application of carpet over pad, and of
thick wood strip or parquet ooring. Some wood ooring
manufacturers may require additional underlayment.
Consult manufacturer’s installation instructions for details.
• Panels may be used in combination with an underlayment
approved by the manufacturer to provide a surface that
is suitable for the installation of resilient tile, sheet
vinyl, or other nish ooring materials. Refer to ooring
manufacturer’s guidelines for specic information related
to the use of adhesives and proper installation details.
Limitations
• Not designed for unprotected exterior use. Exposure to
reasonable precipitation during normal construction delays
will not damage the panels. ADDITIONAL PROTECTIVE
MEASURES MAY BE NECESSARY DURING EXTENDED
EXPOSURE OR ADVERSE WEATHER CONDITIONS.
• Do not install directly over concrete or masonry.
Storage and Handling
• Store panels in clean, dry areas and off of the ground. If
possible, store indoors.
• If stored outside, cover panels with plastic sheets or tarps.
Keep cover open and away from the sides and bottom of
the panels to allow for air circulation.
• Protect edges to avoid damage to the tongue and
groove prole.
• Space units at least 4˝ on all four sides.
