Four checks before you buy
A short framework for buyers who are new to this material
Thermal & Fire
Confirm thermal conductivity and Class A fire claims; curtain wall and roof need system-level reports.
Acoustic Ceiling
Fiberglass tiles for high NRC spaces; compare weight, edge detail and fiber fallout vs mineral fiber.
Installer Safety
Cutting requires dust masks and gloves; archive MSDS and asbestos-free declarations.
Brands & Supply
Owens Corning, Johns Manville, PPG — verify density, water repellency and package compression.
