Instead of silicone, the dry seal system uses gaskets to protect panel joints from water infiltration. Not only does this help to prevent any seepage, it also negates the issue of dust and debris accumulation, so building exteriors can stay looking clean and untouched for long periods of time.

 Additional features including continuous extrusions around the exterior perimeter, as well as secondary gutters help to enhance the structural integrity and water resistance of this attachment system. However, because these installations require more aluminum and greater accuracy during the application stage, they can be up to 30% more expensive than wet seal systems.


This application system was one the first installation developed. As a result, it’s considered one of the more economical attachment systems on the market today.

First, a silicone sealant is applied to each panel to create a tight protective layer against air and water filtration. Then, hooks are rigged to the building wall and a system of clips is used to attach the panels themselves to these hooks. Once they’ve been positioned correctly, they’re simply screwed into place. While this method is quick and affordable, it does pose a few problems.

 Building owners may be concerned  by the amount of dirt and staining that gathers on the silicone layer. These materials are naturally adhesive and can accumulate debris quite quickly. Because of this, building exteriors will need to be continuously maintained; otherwise, the appearance of the paneling will quickly deteriorate.

 Because these systems rely on silicone applications to prevent moisture infiltration, even the smallest patch left bare during the sealing process can quickly begin to gather water. Unfortunately, once liquid does get in between or behind the panels, there is no easy way to remove it. This can lead to black mold developing in the interior structure.

A THERMAL Break are used to separate traditional Z-girts or hat tracks from the backup wall structure, they are universal to any type of cladding.

They will support any cladding that would normally be attached with these methods, or any other type of rail system. Since the effective R-value is extremely efficient compared to any other cladding support assembly, a much thinner wall will accomplish the same or  better results.

Exposed fastener panel systems provide a great combination of form and functionality. These attachment solutions are available in a variety of colours, tones and textures alongside matching flashing to suit the needs of any project.

Panels can be exactly fabricated to meet construction requirements, and because of the unique properties of the construction materials, they can actually be modified during the building process. EF attachment systems are also performance tested for wind and water performance, as well as structural integrity.

Because joints between the panels are exposed, designers recommend adding a secondary weather proof barrier behind the line of installation to prevent any moisture seeping through to the interior wall.
