Ampatex SB 130 is a weather-resistant vapor check and airtight layer in one. All joints, gaps, overlaps, connections and openings must be made airtight. Any damage to the surface must be sealed. Ampatex SB 130 is usually used on the warm side of the insulation. The membrane runs parallel to the eaves on the existing two-dimensional substructure and the overlaps (10 cm) are fastened with concealed nails. The overlaps are glued with Ampacoll XT. Flashing on chimneys, skylights, etc., must be bonded with Ampacoll BK 530, 20 mm at least 15 cm high. Penetrations such as outlet vents, chimneys, etc., should be taped with Ampacoll BK 535 butyl rubber tape, 50 or 80 mm, to make them airtight and rainproof. Porous, dusty or rough surfaces should be pretreated with Ampacoll Primax or Airmax.
