Description
PROMATECT®-L500 is a non-combustible low density calcium silicate board used for the construction of self supporting ducts, 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.
- Used in damp or humid conditions.
- Excellent fire insulation properties.
- ETA No. 06/0218, CE Marked
