- Airtight installation of junction boxes without dry lining in accordance with the requirements of DIN 4108-7, SIA 180 and OENORM B8110-2
- Provides space for up to three junction boxes
- Can be extended at will by cutting and sticking together again
- For cables and conduits up to 20 mm (.79") in diameter
- Lowest VOC rating in hazardous substance test
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 retarding and airtightness layer.
It complies with the requirements of DIN 4108-7, SIA 180 and OENORM B 8110-2 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.

The INSTAABOX can be used on all common airtight substrates used in construction. Recommendations on suitable sealants for connecting it to the airtight sealing layer (e.g. vapour retarder, wood-based panels or mineral substrate) is given in the pro clima application matrix.
Further information can be found in the technical data sheets provided with the sealant.
The bonds should not be subjected to tensile strain.
When the vapour control membrane is sealed, the weight of the insulating material must be borne by lathing. The adhesive tape should be supported by battens if necessary.
Press firmly to secure the adhesive tape. Ensure there is sufficient back-pressure.
Airtight seals can only be achieved on vapour control membranes that have been laid without folds or creases.
Ventilate regularly to prevent build-up of excessive humidity and use a dryer if necessary.
