About the Alfa 1 insulated wall panel
It also works as an internal partition, creating offices or stores inside an existing building without blockwork. With a PIR core it is certified B-s2,d0 at every thickness. It is designed for vertical fixing; horizontal use needs a designer to check the joint.
