PROMATECT®-LS
Non combustible low density calcium silicate board, used for the construction of fire resistant ducts, cladding of sheet metal ducts and to provide fire rated cable and service enclosures.
PROMATECT®-LS is off white in colour and has a smooth sanded surface on one face with a lightly honeycombed texture on the reverse face. PROMATECT®-LS 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 full strength is regained after drying. Board can be painted or wallpapered. Board will not encourage mould growth and is resistant to insects or vermin. PROMATECT®-LS is chemically inert and is resistant to dilute acids and alkalis.

Fire resistant
Moisture resistant
Can be used in damp or humid conditions as performance characteristics are not degraded by moisture.
Long lasting
Performance characteristics are not degraded by age.
Hygienic harmless
Promatect®-LS boards are hygienically harmless, odourless and do not contain dangerous substances.
Finishable
Can be finished with paint or wallpaper.
Insect resistant
Promatect®-LS cement bonded calcium silicate boards are insect and vermin resistant thanks to their cement content.
