Firestopping in sandwich-panel walls can be challenging.
Different substrates often require different tested details, creating complexity for designers, installers and contractors.
The latest Protecta FR Acrylic certification upgrade now includes comprehensive approvals for mineral wool insulated sandwich panel walls.
In many cases, applications already approved for 100mm flexible walls can now also be used in sandwich panel wall constructions when installed in accordance with the tested detail.
The result?
✔ More tested solutions
✔ Greater design flexibility
✔ Simplified specification
✔ Increased confidence on site
As modern construction methods continue to evolve, tested solutions must evolve with them.
