Joinery quantities: aluminium, wood and kitchen

Enter the dimensions you already have: PRAXAO counts the frame and sash profile bars and the glass of aluminium windows and doors, the boards needed to cover a deck or a cladding, or the cabinets, worktop and plinth of a kitchen run. Every system value is editable and none is a manufacturer’s figure.

How to use it

  1. Choose aluminium units, wood boards or a kitchen run.
  2. Enter the dimensions and the number of identical items.
  3. Replace the starting values (profile widths, bar length, gap, module width) with your supplier’s data.
  4. Read the bars, boards or cabinets to order, with the waste included.

Examples

2 aluminium units 120 × 100 cm with 2 sashes, 5 cm profiles, 6 m bars, 10 % waste

Frame profile: 8.80 m, 2 bars. Sash profile: 11.60 m, 3 bars. Glass: 4 panes, 1.58 m² with waste.

Frequently asked questions

Does it design the windows?

No. It counts what a set of dimensions requires. Profile series, thermal performance, wind resistance, glazing build-up and hardware come from the manufacturer’s data and the joiner’s drawings.

Why can I edit the profile width, the bar length or the module width?

They depend on the system and the maker you choose. The values shown are only starting points, never a manufacturer’s reference.

How are boards counted?

Each board covers its width plus the gap, over its length. The area is increased by the waste percentage, then divided by what one board covers, rounded up to whole boards.
