High Quality Thermoplastic Membranes
To date, Sika Sarnafil has produced almost 15 billion square feet of membrane for use on roofing, waterproofing, tunnels, pools and other civil engineering projects around the world. Our roofing and waterproofing membranes are widely recognized for exemplifying the highest standards of quality, reliability and watertight protection.
It all begins with a proven formula. Sika Sarnafil has been using the same basic formulation in its membrane production process since its inception. Today, building owners are assured their roofing system will successfully perform for many, many years.
Sika Sarnafil uses only the highest quality raw materials to produce its membranes. In the U.S., Sika Sarnafil produces Sarnafil and Sikaplan membranes.
Sarnafil
The Sarnafil G Membrane is a thermoplastic PVC-polymer membrane used in adhered systems. Formulated for long-term, direct exposure to the elements, this membrane is fiberglass reinforced, offering exceptional dimensional stability and a low coefficient of thermal expansion. By fully encapsulating the fiberglass reinforcement, there is no risk of delamination or water wicking. As well, a unique lacquer coating is applied to the top of the membrane which gives your roof a “self cleaning” feature that resists staining from airborne dirt and pollutants.
G series membranes offer the following benefits:
- Vapor permeable
- Dimensionally stable
- Highly flexible
- High mechanical strength
- Decay resistant
- Root resistant
- Weather and UV resistant
- Available in six standard colors as well as custom colors
- Available in two standard widths – 6.5 ft and 10 ft rolls
The Sarnafil G410 and S327 EnergySmart Roof® membranes includes the above benefits, along with highly reflective surfaces designed for energy savings. Its reflective properties have been proven to aid in “urban heat island” reduction strategies. It was also one of the first membranes labeled under the EPA’s ENERGY STAR program and aids building owners in their quest for LEED certification.
The Sarnafil G476 waterproofing membrane is a specially formulated fiberglass reinforced thermoplastic sheet specially compounded to remain watertight in sub-grade environments, such as under plaza decks, green roofs, planters, parking garages and balconies. G476 is designed to withstand the rigors of constant dampness, high alkalinity, exposure to plant roots, fungi, and bacterial organisms, as well as varying levels of hydrostatic pressure.
The Sarnafil S Membrane is a thermoplastic PVC-polymer roofing membrane used in mechanically attached systems. This membrane is polyester reinforced, which provides the high breaking and tearing strength needed to prevent excessive elongation and sheet deformation under the stresses produced by the lifting of the membrane in this type of system.
With four decades of proven performance history, our durable thermoplastic PVC membranes are the products of choice by architects, specifiers and building owners who want the peace of mind that comes with buying from the performance leader.
Sikaplan
Sikaplan 5 is a single ply PVC roofing membrane designed for low-slope and steep slope roofing applications. The membrane has an internal polyester scrim reinforcement to provide the tear resistance required for mechanically-attached roof systems.
Sikaplan 45 is ideally suited for applications that require a quality, cost effective roofing membrane from a trusted supplier. The product has a successful track record of use on buildings in many parts of the world of more than 20 years.
Sikaplan 45's white color reflects the sun's solar energy and helps to lower building cooling costs. The product meets the cool roofing requirements of USGBC's LEED program, Green Globes, Energy Star and California Title 24.
Like all Sika Sarnafil membranes, Sikaplan 45 is thermoplastic; allowing seams and flashings to be hot-air welded using the Sarnamatic automatic hot air welder. When welded together, the sheets of membrane become one monolithic layer of material impervious to water and moisture infiltration.
