Weight Calculations in Integrate

How Weights are Calculated:

Glass Weight:

Glass volume (mm3) = actual width (mm) * actual height (mm) * thickness of panes (4/16/4 glass = 8mm thickness)

Glass volume (m3) = glass volume (mm3) / 1,000,000,000

Glass weight (kg) = glass volume (m3) * 2500

Glass weight (lb) = glass weight (kg) * 2.2

The system makes some assumptions when calculating glass weight, so it will likely be slightly different to the number you get from manually calculating it. These assumptions include:

  • there is 1 glass unit in the sash, ticking individual panes doesn't change anything

  • the glass hidden in the rebate is 15mm on all sides

  • we use estimated widths and heights, so if the sightline is 500mm, we use 530mm for the calculation

  • raked and curved glass will act as if they were unshaped

Solid and astragal bars add weight, but are treated the same.

 

Timber Weight:

Timber weight = timber volume (m3) * density (kg/m3)

Volume can be found by writing a validation rule that includes a volume variable, and running it on your drawing.

Density values can be found on this page:

/Production/Settings/weight_calc

They can be adjusted here for survey drawings to change the weights on production outputs.

 

Panels:

Uses panel material, or sash material if not specified. A hardcoded value is used if the thickness and insulation thicknesses aren't specified.

Panel volume = (Panel thickness (mm) - insulation thickness (mm)) * panel area (mm2)

Panel weight (kg) = panel volume (m3) * density (kg/m3)

 

Whole Item Weight:

10% of the item new joinery weight is added on to account for ironmongery, paint, etc.

 

Debugging:

We have a tool for debugging item weight, which is accessed through the Summary tab on the Drawing Board. Clicking this will show more detail about how the weight is calculated.
