What This Trade Covers
- External thermal insulation composite systems (WDVS / Vollwaermeschutz)
- Interior thermal insulation for walls, ceilings, and roofs
- Cold insulation for refrigeration systems and industrial piping

Energy renovation boom
Austria's climate targets and renovation subsidies (Sanierungsoffensive) are driving
massive demand for insulation specialists. Buildings account for roughly 30% of
Austria's CO2 emissions, and the government funds up to €14,000 for comprehensive
thermal renovations. This makes insulation one of the highest-demand construction trades.
WDVS Systems
External thermal insulation composite systems (WDVS) are the most common retrofit insulation method in Austria. Proper installation requires manufacturer-specific training (e.g., Baumit, Capatect, StoTherm). System approval (ETA certification) must be followed precisely to maintain fire safety and warranty coverage.
