Double-Lok® Metal Roof Panel

Double-Lok® metal roof panels feature mechanically field-seamed, trapezoidal leg standing seams and creates durable, weathertight building envelopes. This roof system is ideal for new and retrofit applications, and is commonly used for industrial and architectural applications. Double-Lok® panels can attach to sub framing with concealed, interlocking clips that minimize panel penetrations and increases weathertightness.

Features

Benefits

Panel penetration is eliminated over the entire building envelope other than at the end laps and panel ends which are connected by a compression joint

Assurance of a weathertight building envelope

Factory notched at both ends with pre-punched holes

Field installation efficiency is maximized with installation allowed from either end of building or on both sides simultaneously.

End laps feature a 16 gauge backup plate with pre-punched holes

Allows solid connection at end laps plus proper fastener spacing. Pre-punched holes improve installation; assure proper panel placement.

Fewer exposed fasteners (by 80%) than traditional side lap panels
