Why LP TopNotch® Sub-Flooring is BetterDuring construction, when a structure is open to the elements, standing water can damage the exposed sub-floor. For this reason, LP engineers designed a floor panel that incorporates a patented notch system that quickly drains away surface water. Self spacing tongue and groove edges provide easy installation. You save not only on your floors but time, labor and materials as well.
