If you are in the business of Installing or Maintaining Air Conditioning and Ventilation systems then Aeroseal Duct Sealing can be of benefit to you and your Customers.

New Installations

Are you aware that there is a new Australian Standard for rigid ductwork? AS4254.2 requires that any system supplying more than 3000 l/s is required to be tested for air leaks. This is now incorporated into BCA2013 which essentially this makes it compulsory to comply for new construction. Please click here for more information. To positively seal all potential leaks in a new system involves a great deal of care during both manufacture and installation. There is still the potential that there will be an issue on site. The Aeroseal process can be used before commissioning to give the best opportunity to seal the entire system in position from the inside out. In the current era of high efficiency design and equipment, NABERS, Green Star and Commercial Building Disclosure, air leaks in ductwork are an unsustainable loss which must be rectified. Until now there has not been an effective, efficient and affordable way to seal leaks. The Aeroseal process has now changed that.

Existing Installations

Existing systems have the dual issues of age, with the breakdown of sealants and movement in joints, as well as a lack of access to the installed duct. To provide the Aeroseal process we must firstly seal Ceiling, Wall & Floor Registers, isolate Fans, Coils and other supplementary equipment including smoke alarms. We then directly seal the entire duct system with a minimum of penetrations, access or preparation. All types of duct can be sealed – rigid, flexible, insulated, metal, masonry, P3 or any other material. There is no need to remove dampers. There is no residue left in the duct. The process in normally carried out outside of business hours to reduce any inconvenience to the occupants.

Cleaning of ducts may be required before the Aeroseal process takes place if there is a build-up on the ducts of greater than 3mm.

The Sealant is a safe effective Vinyl Acetate Polymer:

  • It is similar to what is used as a base for chewing gum, hair spray and water based paints.
  • It remains rubbery and flexible after it has cured.
  • UL723 listed for smoke & flame spread
  • UL181 listed for Mould growth
  • It is certified Low VOC
  • It takes approximately 2 hours to cure
  • There is a 3 year Commercial Application guarantee

The Aeroseal sealing process requires no on-going maintenance. It does not affect service openings or any other maintenance procedures. It will provide the benefits of a well-sealed system for many, many years to come.
