Description
Kemwell Corex A1 is a non-combustible fire-resistant board for the protection of steel structures.
Features and benefits:
- Steel encased with Kemwell Corex A1 can maintain its load-bearing capacity for between 15 and 240 minutes.
- The core is reinforced with special additives to enhance fire resistance.
- Both sides are covered with a completely non-flammable fibreglass mat.
- The board is classified as A1 non-combustible in accordance with EN 13501-1.
- Can be installed early in the building program prior to the building being weather tight.
Boards can be fixed using staples (length suitable to board thickness) and Paslode Impulse IM200 / 50 S16 gun. For a more traditional fix steel angles and screws can also be used. Please contact Kemwell Fire for further information relating to the fixing type and method of these boards.
