PROJECT DESCRIPTION

The Wayside Church addition is a new construction expansion designed to seamlessly integrate with the existing facility. The project team selected a comprehensive VaproShield building enclosure system to create a continuous air barrier across multiple substrates while delivering effective moisture management throughout the building envelope.

A key element of the project was the use of VaproLiqui-Shield, VaproShield’s fluid-applied air barrier membrane, applied directly over CMU walls with a roller. The fluid-applied application allowed the membrane to fully conform to the CMU surface, sealing irregularities, cracks, and transitions that are common with masonry construction. This approach provided a durable, continuous air barrier that simplified detailing and enhanced overall building envelope reliability.

PanelShield SA sheet membrane was installed over CDX plywood areas, delivering a compatible, vapor permeable air barrier that tied into VaproLiqui-Shield fluid-applied membrane. To support drainage and drying behind the exterior cladding, VaproShims were installed behind horizontal hat channels, creating a rainscreen cavity that will safely manage moisture through drainage, ventilation, and drying.

On the roof, RoofBlock HT, air and vapor barrier roofing underlayment, was incorporated at critical areas including eaves and valleys, providing added protection at transitions where water exposure is most concentrated.

The result is a cohesive roof-to-wall air barrier strategy that supports durability, moisture control, and long-term building performance for the expanding church facility.
