PROMATECT®-L500

Application

Used for the construction of fire resistant ducts. Used in damp or humid conditions.

Description

PROMATECT®-L500 is a non-combustible low density calcium silicate board used for the construction of self supporting ducts, over cladding of steel ducts and for cable and service enclosures offering high levels of fire performance, moisture resistance and low levels of air leakage.

Boards can also be used to provide fire protection to ensure that critical cables remain functioning in a fire situation.


Features and benefits:

  • 30–240 minutes' fire resistance.
  • Large spans tested for self supporting ducts.
  • Used in damp or humid conditions.
  • Excellent fire insulation properties.
  • ETA No. 06/0218, CE Marked
  • Fire reaction class A1 non-combustible to EN 1301-1.
  • 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 full strength is regained after drying.
  • It will not encourage mould growth and is resistant to attack by insect or vermin.
