Roof/Wall Thimbles

AES roof thimbles are engineered to meet NFPA 37 requirements, featuring heavy-gauge steel construction, 2" of thermal insulation rated for up to 1200°F, and an outer wall air gap for enhanced performance. Each roof thimble comes standard with a heavy-duty slip-fit rain guard and band clamp. The standard finish is high-temperature black paint, with optional 304SS and 316SS versions available for added durability and corrosion resistance.
