1. TwinZip®25
• TwinZip® 25 Architectural Standing is full interlocking roof system, with a double-lock design.
• In standing seam metal roof system, the edges of adjacent sheets of metal roof panels are turned
up and are then interlocked using stainless steel clips. The stainless steel clips are in turn, fastened
to the roof supports.
• This unique interlocking design forms a weather tight unit and unlike other metal roof panels, no rivets
or screws are exposed on the surface of the panels.
2. Key Features
• TwinZip®25 Architectural Standing Seam is a upgrade from the classic corrugated and ribbed style
metal roof panels. Standing Seam roof panels can be used in both roof and wall cladding applications.
• Corrugated and ribbed style metal roof panels such as Metaldek®24 & Metaldek®26 can be
roll-formed using 0.30mm - 0.42mm (BMT) steel. TwinZip®25 Architectural Standing Seam can only
be roll-formed using minimum 0.42mm (BMT) G300 steel.
• With TwinZip®25, the metal roof panels slot together tightly and snugly, and the raised narrow seams
(25mm) provide excellent protection against the weather elements.
• TwinZip®25 Standing Seam requires special crimping tools to manually crimp down the seams during
installation. For long run roof panels, the interlocking process would however, require the use of our
proprietory Robotic Zipper.
• Fasteners would be hidden under the upraised/standing seams where the roof panels interlocked.
Unexposed fasteners would mean lesser maintenance required in the long run.
3. Applications
• The clean vertical lines of TwinZip®25 roof system is much more visually appealing than the classic
corrugated metal roof panels and is strongly recommended for residential housings, presenting a
contemporary look and feel.
• Architectural components such as tapered or curved panels can be used for convex, concave or dome
roof constructions.
• Roof penetration features such as skylights and photovoltaic solar panels, can also be incorporated
into the standing seam roof design.
