Uses
  • for cast iron / SML pipes up to OD ≤ 135 mm – even using conventional connectors
  • material requirement always 1 layer around the pipe
  • zero clearance between the Rollit seals is possible
  • branches 50 mm above the ceiling are possible
  • from the upper edge of the ceiling, insulate 300 mm long with mineral wool (mineral wool A; melting point > 1000°C; apparent density > 40 kg/m³)
Notes
  • the Curaflam® Rollit winding tape must span the entire ceiling height.
  • attachment with aluminium adhesive tape
  • ceiling thickness of at least 150 mm for ceilings made from concrete; porous concrete

Calculation of minimum total OD =

Media pipe OD (with connecter if possible) + 12 mm Curaflam® Rollit tape thickness! Is the result of Media pipe OD (with connector if possible) + 1 layer Curaflam® Rollit (total 2 x 4 mm = 8 mm tape thickness) + 20 mm overlap of Curaflam® Rollit on the edge (4 mm tape thickness) (e.g. 110 mm cast iron pipe OD + 12 Curaflam® Rollit = 122 mm min. core drilling ID)
