Rigid floors with a minimum thickness of 150mm and comprise aerated concrete or concrete with a minimum density of 650kg/m3.
The supporting construction must be classified in accordance with EN 13501-2 for the required fire resistance period.

Sealant Usage
To get a reasonable usage estimate use formula below.
Formula is size of tube (ml) divided by the square area of the seal (width of joint (mm) x depth of joint (mm)) =.
Example. Tube holds 310ml and the joint is 5mm wide x 5mm deep this becomes
310 ÷ (5 x 5) = Number of lineal metres per 310ml tube. 310 ÷ 25 = 12.4 lineal metres.
**Remember to factor in or allow for some wastage**
