ABOUT

ASTRO EJ SEAL is manufactured with different thicknesses of cellular foams. Intumescent graphite-based material applied by a sprayer to both sides of the foam, forms a compressible firestop joint filler resistant to moisture. Graphite-based material expands at a temperature of 160°C – 180°C from the flame side while the foam is compressed allowing the graphite firestop mastic to seal the hole. Supplied in running meter lengths.

Application

Installation in walls. ASTRO EJ SEAL is used to fill gaps and linear joints within fire resistance class EI 240. Resistant to moisture, suitable for indoor and outdoor use.

INSTALLATION asrto_ej_seal_02
  1. The surface before installation must be clean, dry and devoid of dust.
  2. Make sure the size of the joint sealing element ASTRO EJ SEAL matches the width of the gap.
  3. To ensure a perfect seal, use the acrylic sealant ASTRO INTU MASTIC when joining each 1 meter of EJ SEAL. The mastic should also be used in partition junction point, if the hole is irregular.
  4. Place the filler flush to the edge of the floor or a wall.
