Insulation: gross and net
Measure the façade, then subtract selected windows, doors and other exclusions. Treat reveals, flashing and material allowance according to the agreed method.
A clear basis for estimating and ordering.
CONSTRUCT / MEASUREMENTS
Insulation estimates, roof replacement and aggregate balances start with reliable measurements. Construct helps measure prepared spatial data and retain the context behind each result.
Example result500 m² − 80 m² of openings = 420 m² net. Method illustration, not a measurement from the photo.
SEE HOW IT HELPS
A measurement schematic, not a measurement of a photograph. Change values and select façade exclusions.
Net area 420 m²
Material including allowance 453,6 m²
Net = gross − selected exclusions. Material = net × (1 + allowance / 100). Schematic proportions are illustrative. Reveals, flashing and installation rules need separate consideration.
Solutions
Surface area, projection and volume answer different questions.
Measure the façade, then subtract selected windows, doors and other exclusions. Treat reveals, flashing and material allowance according to the agreed method.
A clear basis for estimating and ordering.
Roof surface area and horizontal projection differ. Exclude skylights and other areas to prepare an initial assessment.
Better inputs for a roofer or PV designer, without claiming a complete panel layout.
Define a measurement boundary and reference surface. Compare results using consistent methods, scale and model quality.
Easier tracking of stock or terrain changes.

Illustrative value. Survey results depend on the model, boundary and reference surface.
What we can prepare
Spatial surface measurements and XZ projection, depending on the selected tool.
Named regions contributing to the net result while the gross result remains unchanged.
Model source, scale, date, method and measurement reference.
FAQ
No. Scale, coverage, acquisition method and quality need checking. Required accuracy is agreed before the work.
No. Panel layouts need shading, structural capacity, clearances and other design considerations. Area is an input.
Net area uses selected semantic regions. Preparing and checking them is part of the process; universal automatic detection is not promised.
