Sika Sarnafil membranes are inherently root and algae resistant and require no additional barriers to be added to the system. Sika Sarnafil membranes have passed the most stringent European tests.
Sarnafil® G 410 is a multi-layer, synthetic roof waterproofing membrane based on premium-quality polyvinyl chloride (PVC) with an inlay of glass non-woven and a polyester fleece backing. Sarnafil® G 410 has a unique lacquer coating applied to the top of the membrane to reduce staining from airborne dirt and pollutants. This is ideal for exposed roof applications.
Sarnafil® G 476 is a multi-layer, synthetic roof waterproofing sheet based on premium-quality polyvinyl chloride (PVC) with inlay of glass non-woven. It is ideal for green roof applications and carries a long term warranty.
Sika Sarnafil’s waterproofing membrane is specially designed for sub-grade environments. The G476 membrane is available in a range of thicknesses to match your application, overburden type and specific project requirements. Highly puncture resistant, its color makes it easy to identify and inspect to maintain high levels of quality assurance and control during installation.
Sika Sarnafil Sustainability Promise
LOOSE LAID SARNAFIL MEMBRANE | GREEN ROOF SYSTEMS
Loose Laid Membrane Systems with Sarnafil
Sarnafil has a proven track record of over 50 years with green roof construction. The Sarnafil waterproofing membranes used in these systems are:
Resistant against biological and micro-organisms
Fully resistant to root penetration
Efficient application is also a key advantage of these materials:
Can be installed in most weather conditions.
Loose laying of the membranes provides fast installation
Soil with a minimum weight of 80 kg/m2 provides the necessary wind uplift resistance, eliminating the need for any additional mechanical fastening
MECHANICALLY FASTENED SYSTEMS
Mechanically Fastened Systems with Sarnafil Membranes
Mechanically fastened roofs are the most cost efficient for exposed roofing applications
The fastest installation speed is achieved with mechanical fastening
Sarnafil membranes for mechanical fastening have special polyester reinforcement, enabling high wind load resistance
Installation is almost not weather dependent
Mechanically fastened systems are ideal for large, lightweight metal decked structures and buildings, such as distribution and logistics centres, warehouses, supermarkets, workshops.
Adhered Systems with Sarnafil
Sarnafil adhered systems are a great solution if there is a need for:
High aesthetic appearance
Freedom of design and suitability for complex roof shapes
No penetrations of the roof deck are required
These adhered systems also have additional advantages in many situations such as:
Very low noise emissions during installation
Easy refurbishment of existing bitumen roofs
Sika adhered systems are generally installed on public and residential buildings, including schools, offices, hotels, hospitals, apartments, etc. plus all types of refurbishment projects.
