Air testing is becoming a more stringent regulation, with buildings being designed with a low air leakage rate. 40% of the building's heat loss can be due to uncontrolled air leakage.

ATSPACE has a full suite of services, from the initial drawing review, diagnostic air pressure testing, to the formal air leakage test.

The Air Tightness Drawing reviews are a great way to analyse the architect’s drawings to ensure the air barrier has been considered and the implementation of materials, interfaces and junction details are correct.

There are many factors that need to be considered, and some regulations can contradict each other when it comes to design. These need to be all factored in when looking at drawings.

By using our air tightness testing, consultants who all have a wealth of experience will look at the primary air barrier, which tends to be a red line drawn around the insulation line of the building, and implement a better strategy and a possible secondary measure.

Addressing the problems from design to conception is key. Our advice is to prepare three site visits throughout the build to ensure the designs have been implemented. One thing we can guarantee is that what is on the drawings isn’t necessarily what gets built on site. Get your Air champion booked in to safeguard the designs. By having an experienced air champion on your side, you can not only look at designs, but also have hands-on solutions when these problems arise during the build.

Your SBEM or SAP calculation dictates the air target, but customers have higher expectations with air tightness targets, especially with the hike in energy prices.

ATSPACE will be here for all your compliance needs, and we’re happy to answer your questions without obligation.

The design of the building will impact the air tightness, so you need to ensure that you get this right. It is always easier to fix any issues before they occur, rather than in retrospect.

The design of your build can impact the air tightness more than you might expect. To be air tight, you need to ensure your design is up to scratch! Materials and construction methods also play a massive role in considering air tightness. To build tight, you must build right!
