Air Tightness & Thermography
"15-25% of winter heat loss within homes occurs via air leakage."*
Air leakage is the uncontrolled movement of air through the unintentional cracks and gaps in the roof, walls and floor of a building. Air tightness testing enables you to do three important things. 1. Quantify air leakage by scoring a building and enabling comparisons to national and international benchmarks, 2. provide important qualitative information about air leakage pathways within a building and 3. Inform you ventilation strategy and mitigate mould and condensation risks.
We provide various air tightness services on both residential and commercial projects:
Gain valuable credits for your Greenstar certification and show the industry your project is ahead of the game. Up to 3 credits are available by getting an air tightness test done.
For residential buildings, this allows a tradesperson to fix up as many of the identified air leakage pathways as possible on the spot, leaving you with a more energy efficient, comfortable building within hours. In many cases, testing leaky existing buildings for air leakage identifies several inexpensive and simple quick fixes that will improve comfort and reduce heating and cooling costs, sometimes by up to 25%*.
For larger commercial buildings, qualitative information on air leakage pathways can be extremely valuable prior to a refurbishment
This post construction testing provides you with additional reassurance that your building performs to expectations and also ensures that you are aware of your ventilation requirements based on how much air is naturally moving in and out of the envelope.
We offer advice on basic air tightness strategies through to detailed design advice for your next project. It is important to note that testing new construction is simplest if preceded by an air tightness strategy during the design and construction periods, particularly on large commercial buildings where the required testing equipment can be significantly reduced by a tighter building envelope (read: less expensive test).
This technique is used to detect heat distribution. During air tightness testing, thermography is very useful to create a visual representation of air leakage and insulation defects.
