Polyurethane Foam Consumption Calculator
Estimate the number of 750 mL polyurethane foam cans needed to seal window or door perimeters from total seam length and per-can yield.
How to Use the Polyurethane Foam Consumption Calculator
- Measure the total perimeter of all openings.
- Check the yield stated on the can (default 50 m).
- Click Calculate.
Cas d'utilisation
- •Planning window and door installation.
- •Shopping lists for renovation.
- •Comparing professional vs. household cans.
Formule
Cans = ceil(total perimeter / yield per can). A standard 750 mL can yields roughly 50 metres of 10×10 mm joint.
Questions fréquemment posées
Where does the 50 m yield come from?
Manufacturer datasheets for 750 mL professional cans: typical expanded yield is 40–60 L, corresponding to ≈ 50 m of a standard 10×10 mm window joint.
Should I buy extra?
Yes — add one spare can for primer loss, valve jamming and partial second passes.
