Methodology
Transparent calculation
BuildMeter converts every input to a consistent internal unit, applies the selected allowance, and rounds products up to whole purchasable units.
Net run = exterior sill + interior runs − approved deductions. Multiply by layers, add lap allowance, round to rolls, then round to cases.

FAQ
Sill Sealer Calculator questions
Should door openings be deducted?+
Only deduct locations where no sill plate or gasket will be installed. Many framed wall runs remain continuous during layout.
Does sill sealer replace caulk?+
Not necessarily. Joints, anchor penetrations and irregular gaps may need compatible sealant in addition to the gasket.
What width should be ordered?+
Match the sill plate and project detail. Width is a product-selection decision rather than a length calculation.
