Why Illbruck?

Renaker and the wider project team chose illbruck’s solutions because of the confidence in using a fully compatible system from one provider. This reduced complexity on-site and gave reassurance to the fire engineer, who was closely involved in product sign-off.
Rapidfix continue to use illbruck due to the ease of installation, strong on-site support, and competitive pricing. The Class B VCL, in particular, provided a significant cost saving against other manufacturers. 

illbruck Results and Benefits?

  • Full system warranty provided peace of mind to both contractors and the client
  • On-site toolbox talks and site visits delivered by CPG’s Leanne Eckersley and Tarryn Doody ensured proper application and installation
  • Speed of installation helped the project stay on schedule, with using self adhesive interface seal proving particularly efficient.

Client Feedback “Once Rapidfix began working with the AVCL system, we were very happy with the ease of installation and the support provided on site. The pricing and performance gave us confidence moving forward with the illbruck system.”
