Firestem™
F60 System
The openings and cable penetrations which require to be Fire Rated to a minimum
of 60 minutes are treated with a coat of Firestem™ 1W, around the
opening over a width of 40mm and over the services for a length of 200mm, measured
from the heart of the opening (total length of services treated with Firestem™
1W 2 x 200 = 400mm). Any gaps between cables are filled on site with Firestem™
2.
The opening is then sealed with sheets of mineral wool boards, 50mm thick and
a density of 160 kg/m3. The mineral wool is treated on both sides with Firestem™
1W (approximately 0.75mm thick - 1 litre/m²). Gaps between cables and the
mineral wool boards are sealed with mineral wool fitted tightly around the cables.
These small pieces are treated with Firestem™ 1W and glued in position.
The remaining voids between cables and cabletrays are filled with Firestem™
Mastic over a length of 100mm on both sides of the opening. After the opening
is totally sealed, it is given a final coat of Firestem™ 1W. |
