Vapour diffusion

Uncontrolled air movement accounts for 98% of all vapour diffusion through building envelopes, with the smallest air leakage points will carry moisture to unwanted points in the building.

The CHBA manual states that for every m2 of building envelope, a 20mm x 20mm penetration transports 100 times more moisture through the building in an uncontrolled manner than by any other mechanism – 30 ltrs of moisture per month, rather than 300ml!

Whilst these penetrations will not be uniform, the net level of uncontrolled moisture can be calculated through equivalent leakage area, representing the net size of all penetration through the envelope.


This can impact the operation of intended ventilation and diffusion strategies, reducing efficiencies of mechanical systems and impacting the lifespan of the building. This is further compounded by the non-uniform application of traditional airtightness systems and testing, with the final airtightness value only representing the building’s operation as a single unit.

However, if half of the home is sealed very tightly (e.g. 0.5 ACH), and the other is leaking significantly more (2 ACH), then ventilation strategies will be designed around a net leakage of 1 ACH – oversized by 2x for half of the building, and half undersized for the other.

With AeroBarrier, the active nature of the air sealing process ensures that all areas of the building are sealed to the same degree in a uniform manner. As the building is pressurised during the sealing process, the larger penetrations draw more sealant than the smaller leaks – a 1mm x 1mm penetration draws 1mm2 of air through it, whereas a 2mm x 2mm hole draws 4mm2 of air – the larger the leak, the faster it seals.

As the AeroBarrier gives real-time updates throughout the sealing process, when the airtightness of the building is measured at 1 ACH, you can be sure that this is uniform throughout the building- no more unwanted or unknown leakage points!

Furthermore, the modular set-up of the AeroBarrier system means that if a room is already very airtight, the system self-monitors and shuts off stations in sealed areas of the building – if 3 out of 4 stations have shut off with one station operating continually dispersing sealant, then we can trace leakage by room, not just by building! This can be fed back to trades, contractors and teams to ensure high standards are being followed throughout the build process.

A simple 4 step process


Preparation & setup

We undertake an initial air tightness test to find out what level your building currently has and cover intended areas of air movement (e.g. cooker hoods, shower vents, window/door frames, etc).


Your building will then be pressurised, and AeroBarrierUK’s smart sealing stations will be activated. We will monitor and control each unit’s progress via a computer positioned outside of the building

Monitor & seal

Having reached your desired air tightness level (anywhere from Building Regulations down to Passivhaus), the sealing stations will be deactivated, and your building will gently vent and depressurise.

Verify & certify

Once the process is complete, we will carry out a final post-seal air tightness test. This is an on-site verification of the building’s airtightness and guarantees your air leakage level.
