Single-ply roof membranes are one of the most popular flat roofing materials, ideal for lightweight, cost-effective fast-track construction projects. They work well for a variety of projects with roofs of all shapes and sizes, including exposed roofs, green roofs, cool roofs, ballasted roofs and more, from large scale commercial projects such as airports and factories to a private house rooftop.  

Single-Ply Membranes Are a Popular Choice Because They Are...

  • Durable
  • Fire resistant and fire retardant
  • Chemical resistant
  • Resistant to UV and natural elements such as harmful micro-organisms
  • Eco-friendly
 

Sika’s Single-Ply Roof Membrane Technologies and Advantages

Sika offers two key technologies - polyvinyl chloride (PVC) membranes and thermoplastic or flexible polyolefin (TPO/FPO) membranes. Understanding the differences will help you select the right single-ply membrane for your project.

Polyvinyl Chloride (PVC) Membranes
  • Established technology with the longest track record
  • Availability of products for exposed roofing applications with high fire ratings / extended fire resistance
  • Easy to repair
  • Possibility of customized design solutions (colors, profiles, and roof graphics)
  • Homogeneous hot air-welded joints
  • Easy to handle on site
  • Suitable for use and exposure in different climatic conditions
  • Fast installation independent of the weather
  • Good vapor permeability
  • Highly flexible
  • Flame-free installation
  • Recyclable
  • Proven technology for over 50 years
Thermoplastic or Flexible Polyolefin (TPO/FPO) Membranes
  • High chemical resistance
  • Suitability for direct application on such substrates, as old bitumen, EPS and XPS insulation (polystyrenes)
  • Availability of products for exposed roofing applications with high fire ratings / extended fire resistance
  • Plasticizer free (no migration / contamination or leaching)
  • Long life expectancy
  • Easy to repair
  • Homogeneous hot air welded joints
  • Easy to handle on site
  • Suitable for use and exposure in different climatic conditions
  • Fast installation independent of the weather
  • Outstanding ecological profile
  • Flame-free installation
  • Recyclable
  • Proven track record since 1989

Sika Exposed Single-Ply Roof Membrane Fixing Methods

Method Mechanically-fastened systems with Sarnafil / Sikaplan membranes Adhered systems with Sarnafil / Sikaplan membranes
Applications Ideal for large, lightweight metal deck structures and buildings, such as distribution and logistics centers, warehouses, supermarkets, and workshops. Generally installed on public and residential buildings, including schools, offices, hotels, hospitals, apartments, stadiums, sports centers, plus all types of renovation and repair projects.
Characteristics
  • Mechanically fastened roofs are the most cost efficient for exposed roofing applications
  • The fastest installation speed is achieved with mechanical fastening
  • Sarnafil / Sikaplan membranes for mechanical fastening have special polyester reinforcement, enabling high wind load resistance
  • Installation is almost not weather dependent
  • High aesthetic appearance
  • Freedom of design and suitability for complex roof shapes
  • No penetrations of roof deck are required
  • Very low noise emissions during installation
  • Easy refurbishment of existing bitumen roofs
