Spray Foam Kit Yield Order calculator.
Convert supplied fill-zone volumes into complete foam kits using finished installed yield on the same basis. Does not recommend thickness, chemistry, application, ventilation or fire protection.

Formula and assumptions
How this calculation works.
Convert supplied fill-zone volumes into complete foam kits using finished installed yield on the same basis. Does not recommend thickness, chemistry, application, ventilation or fire protection. V = Σ(net area × specified thickness − known displacement); kits = ceil(V × allowance / selected finished kit yield).
A worked example
Illustrative inputs only. Product properties and design dimensions are not recommendations for your project.
- Product finished installed yield per complete kit
- 1 m³
- Your material allowance
- 10 %
- Measured zone area
- 20 m²
- Excluded area
- 2 m²
- Already specified finished thickness
- 50 mm
- Known displacement within the net zone
- 0.1 m³
Complete foam kits: 1 kits
Use finished installed kit yield, not liquid component volume or an assumed expansion ratio. Thickness and safe application are not recommended.
Before you purchase
Use dimensions from your plan and properties from your chosen product. Any design spacing, section or fixing pattern must already be specified.
Counts quantities from an existing supplied specification. Does not design construction, certify safety, recommend application requirements or establish code compliance.
Example dimensions and product properties are illustrative arithmetic inputs only. Obtain actual yield, density and coverage from your selected supplier.
