Areas of application

For structures without dry lining, the INSTAABOX can create space for junction boxes and the like. It is attached and sealed so that it is airtight to the existing vapour-checking and airtightness layer. It complies with the requirements of DIN 4108-7, SIA 180 and RE 2020 with regard to airtightness when using conventional junction boxes. The INSTAABOX can be used for both internal and external walls.

The INSTAABOX is oversized to prevent the airtight sealing layer being damaged if holes need to be drilled for the junction boxes.
