Minimise Air Leakage Risks from the Design Stage

Early-stage design reviews can identify any air leakage risks and recommend cost-effective design solutions to achieve air tightness targets. Stroma Built Environment offers desktop and on-site design reviews, as well as pre-test inspections to ensure compliance before final air testing and handover.

Desktop Design Reviews

We’ll review your architectural drawings to identify any design faults and potential risks that may affect your development’s air tightness. Our Air Tightness Consultants will provide recommendations to improve the project’s design intent and overall air tightness approach for final compliance.

On-site Design Workshop

Our consultant will visit your site to attend a design workshop alongside your project team. The on-site design workshop will examine the key details of your air barrier design to highlight potential weaknesses or risks at an early stage to recommend improvements to achieve compliance, whilst saving costs.

Pre-test Site Inspection (Audit)

Before final air tightness testing, we’ll arrange a pre-test site inspection to review the air barrier against the design and as-built details. The inspection will examine the air barrier details to identify the potential risks of an air test failure in an illustrated report. Any remedial works can then be actioned to ensure your project is on course to pass its final air tightness testing.
