The same drawing, in Kotelys.
The take-off drawn on the drawing, the quantities sorted by type in the Objects panel, each in its colour.
What you measure, and how.
Three tools are enough: length, area and count. Each type keeps its colour, from the drawing to the report.

Kotelys measures areas and volumes; the thermal resistance and insulation thickness remain those of your design or specification.
Why Kotelys for this package.
One element, one type
Lining 13+100, blown mineral wool, insulation under screed: each has its colour, its total and its line in the reports.
Openings deducted to your contract
Each opening is placed with its own height; the voids-not-deducted threshold is set type by type.
Accurate lofts and slopes
The type's pitch corrects sloping ceilings measured on plan, and the take-off calculations write it out.
Frequently asked questions
Another question? Write to us.
Is Kotelys suited to an insulation contractor?
Yes: linings, lofts, sloping ceilings and floors are measured on the architect's drawing or on a scan, flat by flat. It does no thermal calculation and no grant paperwork: it measures.
Can you get a volume of insulation?
Yes: give a thickness to an area type, and Kotelys writes the volume (“20.00 m² × 0.20 m = 4.00 m³”) in the take-off calculations.
Does Kotelys open DWG files?
No: Kotelys works on PDFs and images, scanned drawings included. Print a DWG to PDF at scale from your viewer.
How do I get the quantities into my estimate?
The Excel export gives a summary and the object-by-object detail, as fixed values. The PDF take-off calculations write out every calculation, to attach to your pricing.
