If AeroBarrier is applied at the optimal time, i.e. between weathertightness up until after plasterboard is installed, there is very minimal preparation required.
Vertical surfaces like walls, doors, and windows require no covering. All designed openings, such as ducts, electrical and plumbing need to be covered before sealing by the AeroBarrier. All finished horizontal surfaces need to be covered – depending on the scale and number of finished surfaces installed, then there may be additional prep work required before the AeroBarrier team arrive.
