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
Increased weathertightness
Air infiltration and water penetration tests under IAS E283 and E331 methods performed on side lap panels
Assures specifiers of minimal air infiltration and water penetration
Signature® 300 paint system
25-year finish warranty
Tall or short clips
Maximizes insulation systems options including 1” thermal spacers at the purlins
Panel side laps feature a factory applied sealant
Facilitates weathertight construction and ease of installation
UL 90 and FM rated
Lower insurance costs
Optional product and weathertightness warranties
Adds to customer confidence
