Owens Corning Q2 2026: Flat sales, resilient 24% EBITDA margin post-glass divestiture; Doors segment pressure continues.
Owens Corning delivered Q2 2026 net sales of $2.756 billion, flat year-over-year, with adjusted EBITDA margin holding at 24% despite a weakening demand environment for discretionary remodeling and residential new construction. The company completed its strategic pivot away from glass reinforcements in April 2026, positioning itself as a pure-play residential building products leader with roofing, insulation, and doors. However, the Doors segment deteriorated 7% in Q2 sales and contracted 240 basis points in EBITDA margin to 11%, signaling integration challenges and market softness; management expects further pressure in Q3, with guidance calling for revenue of $2.6B–$2.7B and adjusted EBITDA margin of 20–22%, a 200-basis-point decline.
