The accelerated pace of market share conversion from wood to composites continues , and our ability to capture a large portion of this expanded addressable market reflects the strength of our brand and the range of our product portfolio , which supports consumer decision - making by providing a range of product aesthetics , features and price points that have broad appeal and distinct competitive advantages over wood . " Strong sales growth coupled with disciplined SG & A spending resulted in significant operating leverage in the third quarter .
