Unlike adhered roofing systems where the membrane is secured to the system using adhesive, Sikaplan Fastened Systems secure the membrane using fasteners within the membrane seam overlap. Typically called an “in-seam" attachment system, after the plates and screws secure the edge of the membrane, the next sheet overlaps the fasteners and is made watertight by hot-air welding the seam. This type of system is considered one of the fastest most cost effective ways to install a single-ply roof. Below are some of the reasons why a Sikaplan fastened roofing system might be the best fit for your project.
