Sikaplan® G-20

2.0 mm thick polymeric PVC membrane for mechanically-fastened roof waterproofing

Sikaplan® G-20 (thickness 2.0 mm) is a multi-layer synthetic waterproofing membrane designed for roofing applications. Manufactured from polyvinyl chloride (PVC), it incorporates an internal polyester reinforcement, in compliance with EN 13956 standards. The product is hot air weldable, formulated for UV exposure and independently assessed for external fire performance. Can be applied in all climatic zones.

  • Highly flexible membrane allows for easy application
  • Increased resistance to damage through wind uplift
  • Hot-air welding application avoids fire risk
  • White coloured membranes reduce air conditioning costs by reducing heat transmission into the building
  • IMPORTANT Requires named reference to an established recycling programme for post-consumer PVC that is easily accessible for > 65 % of customers and that feeds post-consumer recycling material to production of new products.

Compatibilidade

Membrane must be separated from any incompatible substrates / materials by an effective separation layer to prevent accelerated ageing. Not compatible in direct contact with bitumen, tar, fat, oil, solvent containing materials and plastic / thermoplastic materials, e.g. expanded polystyrene (EPS), extruded polystyrene (XPS), polyurethane (PUR), polyisocyanurate (PIR) or phenolic foam (PF). These materials could adversely affect the product properties.

PREPARAÇÃO DA BASE

The substrate surface must be smooth and uniform.

The supporting layer must be compatible with the membrane, resistant to solvents and dry.

  1. Remove any sharp protrusions or burrs from the substrate.
  2. If contaminants such as grease or dust are present, clean the supporting layer.
 

APLICAÇÃO

IMPORTANT

Strictly follow installation procedures

Strictly follow installation procedures as defined in Method Statements, application manuals and working instructions which must always be adjusted to the actual site conditions.

IMPORTANT

Application by trained personnel

The application of this Product must only be carried out by an applicator that is trained or approved by Sika. The applicator must also be experienced in this type of application.

FIXING METHOD - GENERAL

The waterproofing membrane is installed by loose laying – without stretching the membrane or installing under tension – with mechanical fastening in the seam overlaps or independently of overlaps. Overlap seams are hot-air-welded using specialised hot-air equipment.

FIXING METHOD - SPOT FASTENING (SARNAFAST®)

  1. Install the Product at right angles to the deck direction. Unroll the waterproofing membrane, overlapping it by 120 mm.
  2. Fix the waterproofing membrane using Sarnafast® fasteners, barbed washers and tubes along the marked line, 35 mm from the edge of the membrane. The spacing of the fasteners must be in accordance with the project specific Sika calculations.
  3. At upstands and at all penetrations, secure the Product with a Sarnabar®.
  4. Use the 4 mm diameter SikaRoof® Welding Cord PVC to protect the roof covering against tearing and peeling off by wind uplift.

FIXING METHOD - FIELD FASTENING

  1. Install the membrane at right angles to the deck direction. Unroll the waterproofing membrane, overlapping it by 80 mm..
  2. Fix the membrane by induction-welding Sarnadisc hot-melt-coated washers and Sarnafast® fasteners along the marked line, 35 mm from the edge of the membrane. The spacing of the fasteners must be in accordance with the project specific Sika calculations.
  3. At upstands and at all penetrations, secure the Product with a Sarnabar®.
  4. Use the 4 mm diameter SikaRoof® Welding Cord PVC to protect the roof covering against tearing and peeling off by wind uplift.  

HOT-WELDING OVERLAP SEAMS

Overlap seams must be welded by electric hot-welding equipment. Prior to welding, welding parameters including temperature, machine speed, air flow, pressure, and machine settings must be evaluated, adapted and checked on site according to the type of equipment and the climatic conditions. The effective width of overlaps welded by hot air must be a minimum of 20 mm.

TESTING OVERLAP SEAMS

  1. Mechanically test seams with a rounded-edge screwdriver to ensure the integrity and completion of the weld.
  2. Rectify any imperfections using hot-air-welding.
