Air Barrier & Weather Barrier Testing
Comprehensive air barrier testing and weather barrier assessment to diagnose infiltration pathways, identify envelope discontinuities, and verify airtightness performance in building envelope assemblies.
Air barrier testing evaluates the continuity and performance of air control layers within building envelope assemblies. Using blower door testing, smoke visualization, and thermal imaging, we identify air leakage pathways that compromise building energy performance, allow moisture infiltration, and reduce occupant comfort.
Effective air barrier systems are critical for building envelope performance in BC's climate. Air leakage transports moisture into wall cavities through infiltration and exfiltration, leading to condensation, mold growth, and structural deterioration. Discontinuities at material transitions, penetrations, and interface details create pathways for uncontrolled air movement. Professional air barrier testing identifies these deficiencies and provides data for remediation and energy efficiency improvements.
Our Testing Process
Blower Door Testing
Pressurization and depressurization testing to quantify air leakage rates and identify areas of significant air infiltration.
Thermal Imaging Survey
Infrared thermography during pressurization to visualize air leakage pathways, insulation defects, and thermal bridging.
Smoke Visualization
Smoke pencil testing at suspect details to identify specific air leakage locations and envelope discontinuities.
Performance Report & Recommendations
Detailed analysis of air barrier performance with quantitative leakage data, failure locations, and remediation guidance.
