What Is Sika Sarnafil?
Sika Sarnafil is a PVC-based, single-ply membrane system. It’s been used in commercial roofing and waterproofing applications for more than 60 years, making it one of the most time-tested PVC membranes and roofing products on the market.
Manufactured by Sika, a worldwide leader in waterproofing membranes, Sarnafil membranes are formulated to withstand extreme global climatic conditions, from desert heat to freezing alpine temperatures.
But, Sarnafil is more than just a roofing product. Sika Roofing solutions are designed to meet the long-term durability and sustainability needs of commercial facilities and buildings. Many airports, stadiums, schools, and high-rises are protected by Sika’s Sarnafil membrane, making it one of the most used products in the roofing industry.
Key Features of Sika Sarnafil

- Sarnafil membrane is made from a proprietary PVC formula. It resists UV, hail, and chemical damage, even under direct exposure.
- Sustainable Manufacturing
- Sika’s Cradle-to-Cradle certified products reflect a commitment to circular, environmentally responsible practices. These products are designed with sustainability in mind, are built to last, and are easy to recycle at the end of their lifespan.
- System Compatibility
- Sika Roofing systems are compatible with green roofs, solar panels, and other building systems, making them ideal for modern high-performance roofing.
