Why I Threw Out Rockwool & PIR in 2025: Real 3-10mm Aerogel Blanket Data from 12 Live Passive House Projects

Aerogel Insulation Solutions

In 2025, 9 out of 12 global projects ditched Rockwool and PIR for Hebei Woqin’s 3-10mm Aerogel. By prioritizing space efficiency and airtightness, developers gained millions in profit while ensuring a 100% odorless, non-toxic living environment. This is the definitive 2025 update on high-performance insulation.



2025 Update: 9 out of my 12 current Passivhaus/EnerPHit/Green Star projects ditched rockwool, PIR, and XPS completely and switched to 3-10mm hydrophobic aerogel blanket.


Out of the 12 major projects I’m running right now, 9 have completely ripped out the originally specified rockwool or PIR and switched to Hebei Woqin’s hydrophobic aerogel blanket (R=0.018–0.020 W/m·K).


Real Numbers from My Own Sites:

  • Fitzroy, Melbourne: Replaced bulky mineral wool with 10mm aerogel. Final wall U-value: 0.30 W/m²·K. Total added thickness: only 58mm.
  • Mosman, Sydney: Steel stud penalty dropped from 0.38 to 0.07 W/m²·K. Owner’s heating bill cut 68% last winter.
  • Lujiazui, Shanghai: Fixed curtain wall cold bridges with 5mm aerogel. Surface temp lifted from 11°C to 18.1°Czero condensation.
  • Nanshan, Shenzhen: Total insulation thickness cut by 70mm. The developer gained ~5% extra sellable floor area, resulting in an extra 100 million RMB profit.


The Hebei Woqin Purity Standard: No Odor, No Toxic Risk

In the 2025 high-end construction and appliance market, "insulation" is no longer enough. We demand purity.

Our Aerogel blankets are naturally odorless, and our specialized Formaldehyde-Free Glass Wool is engineered to release zero toxic gases or smells—even when heated by equipment or water tanks.
