Less Rework – Minimized Liability

Rework Required

Lessrework_1 resize

Poorly installed weather resistive air barrier resulted in major rework and over 75% of construction defects are due to water intrusion, air leakage, and poor workmanship.

QAP In-process Repair

An installation error was noted by a QAP auditor during a routine quality control site visit.

The flaw was quickly rectified (no rework or change order required) thus avoiding possible moisture and air intrusion after the cladding was installed.

Multi-Faceted Approach – Integrated Components

Contractor Accreditation

QAP contractors are trained, accredited, and have signed agreements with ABAA to follow installation guidelines and correct deficiencies.

They must meet bonding/insurance requirements, employ ABAA certified installers, and possess the equipment to install and test their work.


QAP installers are trained and certified by ABAA. To qualify they  must have a minimum of 3,000 hours of documented work experience in air barrier/water resistive barrier installation.

Typically, certified installers work for QAP accredited contractors.


ABAA has tested over 100 manufacturer air barrier WRB assemblies that were tested in accordance with ASTM E2357 and many other stringent evaluation criteria.

By specifying evaluated materials, design professionals can limit their liability and be assured that materials will meet and exceed stated specifications.


Each day, certified installers are required to document the installation process, inspect, and fix deficiencies.

The reports are submitted to the construction site QA office and, in turn, provided to the general contractor and design professional.

Onsite Field

ABAA field auditors confirm compliance with project specifications, manufacturer installation guidelines, and ABAA Site Quality Assurance Program. Auditors review substrate preparation, compatible materials, applications, and repair procedures.

Audit findings are distributed to the: owner, architect, manufacturer, GC and accredited contractor.

Final ABAA Audit

Upon audit completion, the final report, including a photo log, is submitted to the ABAA Site Quality Assurance Program office for a final review by seasoned building science professionals.

Thereafter, it is filed and distributed to the owner, architect, manufacturer, GC, and accredited contractor.

Proven Approach – Mitigate Claims

For a fraction of the overall building cost, you can ensure PROPER MATERIALS, PROPER INSTALLATION, and PROPER INSPECTION for the most difficult to maintain component of your building: the wall assembly and air barrier system.
