Ply Gem Market Overview

According to Grips Intelligence in-store data tracked across Lowe's and Home Depot from January 1 to September 30, 2026, Ply Gem — a brand within privately held Cornerstone Building Brands — holds a nearly even split between its two retail channels, with Lowe's accounting for 51.6% of year-to-date revenue and Home Depot 48.4%. The brand's average product price sits at $64.11 across the measured period, signaling a mid-tier price position. Revenue has grown 10.5% over the tracked span, though the most recent month registered a 2.6% decline versus the prior month. Average selling price has trended upward in the third quarter, reaching $68.86 in the latest month — a 1.7% month-over-month gain and roughly 1.0% higher overall. The combination of rising prices and a near 50/50 retailer split suggests balanced distribution leverage, with monthly revenue volatility worth monitoring into Q4.
