PROMATECT®-L

ADVANTAGES

  • Non-combustible
  • Moisture resistant
  • Rot

Matrix engineered calcium silicate board

PROMATECT®-L is a lightweight mineral matrix engineered board which is white in colour and has a smooth sanded surface on one face with a lightly honeycombed texture on the reverse face.

PROMATECT®-L is resistant to the effects of moisture and will not physically deteriorate when used in damp or humid conditions. Performance characteristics are not degraded by age or moisture. Untreated surfaces will absorb water which can cause some loss of strength but strength is regained after drying. PROMATECT®-L does not encourage mould growth and is resistant to attack by vermin. PROMATECT®-L is chemically inert and is resistant to diluted acids and alkalis. Boards should be protected where high chemical concentrations are likely to occur.
