Q1: What is airtightness in building construction?

Airtightness measures how effectively a building prevents uncontrolled air leakage through its envelope.

Q2: Why is airtightness important in modular buildings?

Better airtightness improves energy efficiency, indoor comfort, moisture control, and HVAC performance.

Q3: What do international buyers usually evaluate?

Buyers commonly assess air leakage test results, insulation performance, sealing quality, energy efficiency, and compliance with building standards.

Q4: What are the future trends?

Future developments are expected to include advanced sealing materials, digital performance testing, smart building envelopes, and stricter energy regulations.
