- 120-iseju Rating: Required for building separation walls, exit enclosures (stairwells), and atrium walls. This tier demands a thicker core and steel face skins.
Rule of thumb: Always confirm with the AHJ before you issue your shop drawings. Never assume a 60-minute assembly will pass a 90-minute inspection.
2. Select the Core Material (Mineral Wool, Stone Wool, or Intumescent Honeycomb)
The core is the heart of the panel. A standard ACP (polyethylene core) is combustable. Akoko. Do not use it for fire-rated walls.
Your fire-rated core options are limited to three classes:
- Mineral wool (MW): Density between 100 kg/m³ and 180 kg/m³. Provides 60–90 minutes of fire resistance. Best for thermal insulation (U-value down to 0.35 W/m²K). Moisture-sensitive if seals fail.
- Stone wool (SW): Higher density (180–250 kg/m³). Withstands temperatures up to 1,200°C. Required for 120-minute ratings. Silikoni-free mojuto idilọwọ awọn delamination awo.
- Aluminiomu oyin pẹlu intumescent fẹlẹfẹlẹ: Aṣayan ti o kere julọ (àdánù feleto. 8-12 kg/m²). Layer intumescent gbooro ni 180°C lati ṣe idena eedu kan. O dara fun awọn agbegbe jigijigi ṣugbọn iye idabobo kekere (U-iye isunmọ. 0.8 W/m²K).
