Ampatex A primo plus
Neu
Non-combustible reflective vapour check and electrical smog barrier
Used as a vapour check, airtight membrane and electrical smog barrier.
- sd value 50 m: vapour check
- Fire behaviour: A2-s1,d0
- Non-combustible: no contribution to fire, low smoke development
- Extremely high tensile strength: holds insulating material securely in place
- Surface made of micro-perforated aluminium foil: reflects heat and electromagnetic radiation
Used as a vapour check, airtight membrane and electrical smog barrier on the warm side of the thermal insulation in roofs, walls, floors and ceilings in externally diffusion-permeable constructions. Ideal for blow-in thermal insulation, thanks to extremely high tear values.

Ampatex A primo plus
Ampatex A primo plus functions as both a vapour check and an airtight layer. All joints, crevices, overlaps, connections and holes must be airtight. Any damage to the area just be sealed. Ampatex A primo plus is installed on the warm side of the insulation in dry interior construction and fixed in the overlap area using concealed staples or nails. The smooth, printed side faces the interior of the room and is the side used for bonding. Ensure that the membranes overlap by 10 cm during installation. Seal the overlaps to form an airtight bond using the integrated tapes or the system adhesive tape Ampacoll A Tape silver. Rub down adhered areas thoroughly. Cross joints must also overlap by 10 cm and be bonded with Ampacoll A Tape silver. On furring that cannot be nailed, the double-sided adhesive tape Ampacoll DoubleSeal serves as a mounting aid. The final fixing is carried out when the interior lining is installed. Ampacoll Profix liquid adhesive can be used for connections. These must then be covered with the membrane or the adhesive tape Ampacoll A Tape silver.
Porous or dusty surfaces should be pre-treated with Ampacoll Primax or Ampacoll Airmax.
Attention: Never allow the membrane to come into contact with fresh mortar, cement or other alkaline products. This may damage the aluminium layer.
