Terasun TSM — Exterior sheathing board
🌧️ Exterior sheathing board
Exterior Sheathing Board and Exterior Wall Board
Exterior wall board must remain dimensionally stable through freeze-thaw cycles, wind-driven rain, and temperature extremes. Terasun TSM cement board passes EN 12467 Category A moisture and durability tests — the highest classification for cement boards in European use. Unlike timber sheathing, it does not swell, rot, or lose structural integrity when wet.
Application
Cement board sheathing and cladding for exterior wall systems — render carrier, facade board, and weather-resistant wall substrate.
