Air Tightness Testing

Air Tightness Testing

Air tightness testing, often known as "blower door testing", evaluates how well a building prevents air leakage. For retrofit projects, a unique approach, the pulse test, is also effective. This test method involves a rapid, controlled pressure pulse that measures air tightness more quickly and with less disruption to occupants.


Both testing methods identify gaps, cracks, and poorly sealed areas within the structure, offering detailed insights into where improvements are needed to maximize energy efficiency and comfort.

Boosted Energy Efficiency

Air tightness testing identifies areas of energy waste, enabling targeted upgrades that improve energy savings and design efficiency.

Cost Savings

Addressing air leaks reduces strain on heating and cooling systems, leading to immediate savings on utility bills.

Enhanced Comfort

Sealing air leaks creates a more consistent indoor temperature, improving comfort and reducing drafts.

Improved Air Quality

Air tightness testing helps reduce pollutants and allergens, leading to better indoor air quality and a healthier environment.

Regulatory Compliance

Meeting PAS2035:2023 standards ensures compliance and can qualify retrofitted buildings for sustainability certifications and incentives.

Detailed Leakage Assessment

Technicians conduct a thorough leakage assessment to identify air leaks around doors, windows, walls, and ceilings, helping to pinpoint problem areas in older buildings.

Test all potential leakage points, including doors, windows, walls, and ceilings, to identify air leaks effectively.

Special attention is given to the unique challenges of older buildings where air leaks are more common..

Identify critical areas where energy loss occurs most, enabling targeted retrofitting solutions.

Addressing air leaks ensures a tighter building envelope, improving energy efficiency and reducing heating and cooling costs.

Blower Door and Pulse Testing Options

Offer both blower door and pulse testing options, providing flexibility to suit your building's needs. The pulse test is a faster and less intrusive method, making it ideal for occupied retrofit projects.

A standard method for identifying air leaks by pressurizing the building, helping pinpoint problem areas that require sealing.

A quicker, less invasive technique that uses sound pulses to detect air leaks, perfect for occupied retrofit projects with minimal disruption.

Choose between blower door and pulse testing based on your building's specific needs and occupancy situation.

Both testing methods help ensure optimal air tightness, leading to improved energy efficiency and comfort.

Clear Reporting and Actionable Recommendations

Deliver a detailed report that highlights air leakage areas and provides prioritized recommendations for targeted improvements, aligning with energy efficiency goals.
