Sika-Trocal INNObond/ INNOfix
Application

Thermal insulation underneath waterproofing layer in:

  • Sika-Trocal INNObond: Sika-Trocal SGK Felt adhered single-ply membrane systems.
  • Sika-Trocal INNOfix: Sika-Trocal S/ SG mechanically fastened single-ply membrane systems and Sika-Trocal SGmA loose-laid membrane systems with ballast.

The whole system structure consists of single ply membrane (Sika-Trocal S/ SG or SGK), fasteners and fixings, adhesives (for INNObond) and the S-Vap range of vapour control layers.

Description

Sika-Trocal INNObond is a rigid insulation board, faced on both sides with a wet lay-coated glass fibre tissue, adhesively bonded to the insulation core during the manufacturing process. The core is manufactured from a high-performance CFC-/ HCFC-free rigid urethane insulant with a typical density of 32 kg/m³.

Sika-Trocal INNOfix is a rigid insulation board, faced on both sides with an aluminium composite foil, adhesively bonded to the insulation core during the manufacturing process. The core is manufactured from a high-performance CFC-/ HCFC-free rigid urethane insulant with a typical density of 150 kPa at 10% compression. Completely gas-tight.

Features and benefits:

  • Very low thermal conductivity.
  • CFC-/ HCFC-free with zero Ozone Depletion Potential (ODP).
  • Suitable for new construction and refurbishment.
  • No separation layer for membranes is required.
  • Low adhesive consumption.
  • High compression strength.
  • Supports high adhesion with appropriate Sika-Trocal adhesives.
  • Lightweight and low load on the roofing structure.
