“AeroBarrier is up to 3x FASTER than traditional sealing methods”
Enhance primary airtightness layer
Resolve junction and penetration leakage points, up to 12mm in diameter
Inclusion in drawings either through direct detailing or via (optional) in description – provide option for either UL drawing description, or PassivHaus. Full details upon request.
AeroBarrier integrates and adheres excellently with all common building substrates, membranes, and air sealing systems, with no adverse chemical reactions. Systems retain their flexibility and durability regardless of the system employed.

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.
AeroBarrier has sealed houses to as low as 0.11 ACH50. The value is in the system’s ability to seal a home as tight as it is designed for.
AeroBarrier can meet any Building Regulations Requirements, from England & Wales, Scotland, or N. Ireland regulations, right down to Low Energy/Net Zero Levels, such as International Energy Conservation CodeIECC), Passivhouse / Passivhaus Trust, EnerPHit, and the AECB Building Standards.
Third-party lab testing reveals AeroBarrier withstands a simulated 50-year durability test, with little or no seal degradation.
AeroBarrier has been used in apartments as small as 46 sqm and homes over 1,000 sqm.
As long as the space can be pressurised, it can typically be sealed. Additional blower doors can be added to increase the pressure in larger spaces.
It is based on water-borne acrylic that has been used as a fluid-applied permeable air barrier for many years.
