Ply Gem

Ply Gem Market Overview

According to in-store data from Grips Intelligence covering January 1 through August 31, 2026 across Home Depot and Lowe's, Ply Gem — a brand of privately held Cornerstone Building Brands — maintains a near-even split between the two retailers, with homedepot.com accounting for 50.7% of year-to-date revenue and lowes.com the remaining 49.3%. That balance is unusually tight for a brand of this scale, suggesting neither retailer functions as a dominant distribution anchor. Average product price sits at $62.55 year to date, though the most recent monthly reading of $67.71 points to a 14.7% increase in average price over the tracked summer period. Revenue momentum has been choppier: the latest month rose 13.5% sequentially, yet overall revenue is down 8.9% across the June–August window. The combination of rising prices and softer aggregate revenue indicates volume pressure being partially offset by mix or pricing gains.
