Calculation method
Calculation method
Sealant volume (ml)
sum(r[1]*r[2]*r[3] for r in a)*(1+c)
Cartridges
ceil(sum(r[1]*r[2]*r[3] for r in a)*(1+c)/b)
Backing rod length (m)
sum(r[1] for r in a)
Symbols and units

Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.
Calculation steps and notation
sum(list) adds all entries in the list.
Assumptions & limits
Assumptions & limits
- Supplied rectangular sealant profile and compatible backing dimensions. No joint movement capacity, sealant selection or fire performance inferred. Supported limits: All numeric inputs must be finite. Only the explicitly described mathematical scenario is supported.
