Cassette Fixing - narrow joint


Suitable for application on both existing and new constructions

SOLIDAL® T3® (3mm) and T4® (4mm) narrow joint cassette installation is designed for rainscreen - open joint installation on external areas such as walls and soffits. Double-folded edge Solid Aluminium Cassette is a cost effective solution, that is pre-fabricated in a factory environment according to clients requirements. Delivered directly to site ready for installation or to clients factory for inspection prior to the install process. 


A large variety of designs can be achieved with SOLIDAL® pre-fabricated Cassette modules. For large SOLIDAL® cassette modules, the combination of supporting stiffeners and internal angles are fixed to back of SOLIDAL® sheet, and either spot welded or fixed with structural adhesives, to ensure strength of module and flatness is maintained. The use of additional supporting angles and stiffeners is dependent on size of SOLIDAL® modules.


Calculations are completed on a project by project basis, so the SOLIDAL® Cassette modules are not over or under engineered for the required application.
