Sarnafil Plus Refurbishment Options

Sika Sarnafil is the leading manufacturer of single ply roofing systems. Essentially, our single ply membrane is a strong, flexible PVC or FPO material. All permanent joints are fusion welded via a hot air heat welding process. It can be either mechanically fixed, fully adhered, or loose laid ballasted to the roof surface.
