101BRMF: VISTAFOLD Single & Double Glazed Bottom Rolling Multi-fold Door

Envirotech Façade Solutions has started our design process with a blank sheet. Instead of short cutting the process and utilising the traditional top hung, to rolling bi-fold systems currently on the market, EFS has instead designed a high performance commercial multi-folding door to suit todays’ requirements, standards, codes and architectural trends.

In conjunction with Hillaldam Access Systems EFS has developed what is the most advanced, highest performing and flexible multi-fold door system available in the market today.

This system has the ability to accommodate 75kg sash weights translate to designers and fabricators being able to glaze thicker and therefore larger pieces of glass than many of the other suites currently on offer to the market.

From a performance perspective, these features mean that designers need not compromise their designs in order to achieve performance requirements for thermal, acoustic, structural and water ratings.

The EFS 101BRMF VISTAFOLD suite is complimented by its ability to seamlessly integrate with our framing systems allowing for highlights and side lights. This system also suits almost all locking hardware on the market in Australia currently.

Please contact our friendly sales or technical staff for help with your design requirements and if required, we can help customize a solution for your next project.
