A look inside
Questions
What does the cost estimate include?
Glass, resin and gelcoat from your laminate schedule, plus an Other Materials line-item table (core, timber, fasteners, paint, fittings) — rolled into a project grand total in AUD with a waste margin.
Does it handle different cloth types?
Yes. Pick from presets (CSM, woven roving, biaxial, plain cloth) and the gsm and resin:glass ratio fill in automatically — or type your own for a custom cloth.
Is it metric?
Yes — square metres, kilograms, litres and Australian dollars, in Excel or Google Sheets.
