Aluminium Robust Secret Fix Soffit

Our Robust Secret Fix Soffit, as the name implies, means that the soffit panels have zero visible fixings. We press with solid aluminium and a robust jointing detail to eliminate sagging and enable wider format soffit panels. 

Lengths can be supplied up to 4m long and we offer a wide range of gauges to suit all applications.  Our internal union joints and secret fixing detail eliminates the need for visible penetrations and presents smooth unbroken lines.
