AeroBarrier Vs Conventional Air Sealing For New Construction
A builder-focused comparison of AeroBarrier and conventional air sealing for new construction, with guidance on using mid-construction blower-door testing before drywall.
Aerosol sealing can be valuable when the air barrier is already buried and conventional access is gone. That is why it often makes sense in retrofit situations or late-stage rescue scenarios.
New construction is different. During framing and pre-drywall, the air barrier is still visible. Builders can tape, caulk, gasket, and detail the actual leak paths before finishes make those fixes harder. The key is measuring early enough to know where the weak points are.
A mid-construction blower-door test gives builders that feedback before the final occupancy test. Apollo’s position is practical: use conventional detailing while the assembly is open, test it while it is still fixable, and reserve aerosol sealing for projects that truly need it.
What builders ask before booking.
Is AeroBarrier bad?
No. It can be useful when conventional access is limited. The practical question is whether a new build can solve the leakage with visible air-barrier detailing and early testing first.
What is the builder-friendly alternative?
Detail the air barrier carefully, run a mid-construction blower-door test, fix visible leak paths, then confirm at final.
When should I decide?
Before drywall. Once the air barrier is buried, the cheapest fixes are usually gone.
