Full certification tablesInsulated wall panels & cladding questions
Visible or hidden fixing?
Visible-fix panels (Alfa 1, Alfa 2) are cheaper and faster; hidden-fix (Star, Wall Design) give a clean facade with no screw heads. Performance is the same at the same thickness.
Can wall panels be fitted horizontally?
Wall Design is made for horizontal, bottom-up installation. Alfa panels are designed for vertical installation; horizontal use needs a designer to check the joint.
