Our Airtightness
Services

About airtightness testing
  • Airtightness Testing

    Measure building air leakage and assess performance against project targets.

  • Draught Detection

    Identify unwanted air leakage around windows, doors and construction joints.

  • Smoke Leak Tracing

    Pinpoint concealed air leakage paths using controlled smoke.

  • Construction-Stage Testing

    Identify airtightness defects before they are concealed by internal finishes.

  • Retesting & Performance Verification

    Assess airtightness improvements following remedial works or upgrades.

Why air tightness matters

A tighter building.
A better place to be.

An air permeability test helps you understand how your building performs and where improvements are needed. Testing early gives your team time to act before completion.

  • Identify air leakage early
  • Pinpoint problem areas before they become costly
  • Give your team time for remedial improvements and help achieve the target air permeability rate
