Secret Fix - SFS1

The method of fixing rainscreen cladding can have a dramatic effect on the overall look of the building. Options for our rainscreen cladding solutions can be hook on, face fix, secret fix or whatever you require to suit your needs.

Secret fix, unobstructed by any visible fixings, gives a building a sheer smooth facade that complements the modern aesthetic. Taller buildings and increased occupancies are driving a need for additional safety features and may be more appropriate for a face fix system.

Our technical team are able to offer advice on all aspects of support systems for rainscreen cladding, including passive fire protection in tall buildings:

• Professional software for anchor design

• Selection of right anchor based on base material and loading

• Pull out test of anchors at project sites, along with a test report

• Training to specifiers and contractors on anchor design, installation and quality checks
