  • Waterproofing Attachment: Sarnaweld Mechanically Fixed System / Sarnafast Mechancically Fixed System / Sarnabar Mechanically Fixed System (subject to Sika® specification).
  • Insulation: Sikatherm® PIR AL Insulation / Sikatherm® PIR AL Tapered Insulation / Sikatherm® MW DD Insulation / Sikatherm® MW DD Tapered Insulation.
  • Insulation Attachment: Mechanically Fixed with Sika® SBT thermally broken tube fasteners and SBIW insulation washers
  • AVCL: SikaBit® VB SA-724 / S-Vap 5000E SA.
  • Primer: Sika® Primer 610 Spray.


- Waterproofing:

Polymeric FPO membrane.

  • Resistant to UV exposure.
  • Resistant to permanent wind exposure.
  • Resistant to all common environmental influences.
  • Hot air weldable.
  • No open flame equipment required.
  • High dimensional stability from glass fleece inlay.
  • Resistant against impact load and hail.
  • Resistant to mechanical influences.
  • Resistant to root penetration.
  • Compatible with old bitumen.


- Waterproofing Attachment:

Mechanically fixed.


- Insulation:

Sikatherm® PIR AL is an insulation board for flat Roofing.

It is faced on both sides with an aluminium composite foil bonded to the insulation core and produces a tough, durable, light weight insulation board.


Sikatherm® MW DD/Tapered is an insulation board, faced with a mineral fibre tissue, bonded to the insulation core during the manufacturing process. The core of Sikatherm is high performance mineral wool with a typical density of 220 kg/m³ (top layer).


- Insulation Attachment:

Mechanically Fixed with Sika® SBT thermally broken tube fasteners and SBIW insulation washers.


- AVCL:

  • SikaBit® VB SA-724 is an SBS modified bituminous, self-adhesive air vapour control layer. It is reinforced with aluminium foil and a dimensionally stable non-woven polyester inlay. The underside has a removable liner over the adhesive compound for an easy application. It can be applied to wood, metal and concrete substrates. Top surface finish: sanded bitumen. Weight:~3.0 kg/m².
  • Sarnavap® 5000E SA is a multi-layer self-adhesive vapour control layer made of polymer modified bitumen with a glass-fibre mat reinforcement and an aluminium foil as top layer.


- Primer:

  • Primer-610 Spray: Solvent-based synthetic-rubber bonding agent in a pressurized canister system.
