100

This standard governs the design and construction of masonry structures in the U.S.

What is TMS 402/602?

100

This product, placed at the base of a masonry cavity wall, prevents mortar droppings from blocking drainage and keeps weep holes clear.

What is a mortar collection device?

100

Over time, brick does this as it absorbs moisture.

What is grow or expand?

100

Masonry veneer anchors secure the veneer to the structural back up and transfer these types of loads.

What are lateral loads?

100

Installed across the entire cavity width, this type of flashing directs water out of the wall at critical points such as shelf angles, foundations, openings, etc.

What is through wall flashing?

200

This property of masonry walls can reduce peak heating and cooling loads by storing and releasing heat energy.

What is thermal mass?

200

Installed horizontally in bed joints, this steel product strengthens walls and helps resist cracking.

What is joint reinforcement?

200

These vertical joints in CMU walls are used to accommodate shrinkage and thermal changes, helping prevent random cracking.

What are control joints?

200

Placed between the structural backing and veneer, this layer helps reduce energy loss by resisting the flow of heat.

What is insulation?

200

Placed at the ends of flashing, these vertical pieces prevent water from running off the edges and into the wall.

What are end dams?

300

What is the maximum cavity allowed per TMS 402/602 prescriptive requirements.

What is 6 5/8 inches?

300

This component spans wall openings to support masonry above.

What is a lintel?

300

These joints are placed in brick veneer to relieve stress caused by expansion and to prevent unsightly cracking.

What are expansion joints?

300

This system component is continuous and critical for keeping air and moisture from leaking into the building.

What is the air barrier?

300

This component mechanically secures flashing to the backup wall and prevents water from migrating behind it.

What is a termination bar?

400

To meet IECC energy efficiency requirements, designers may specify this type of shelf angle modification to reduce thermal bridging.

What are offset shelf angles?

400

Weeps in a masonry cavity wall must be located directly above this component to allow collected water to drain.

What is through wall flashing?

400

Brick and CMU expand and contract at different rates, requiring this type of joint at intersections.

What is a movement joint?

400

In a masonry wall, this system includes termination bar, weeps and vents, mortar collection device, drip edge, corners and end dams.

What is the flashing system?

400

These openings are located near the top of the cavity to allow air circulation and help the wall dry.

What are weep vents?

500

This type of metal should be considered when selecting masonry veneer anchors for projects looking for maximum thermal efficiency.

What is stainless steel?

500

When continuous insulation is added to masonry walls, these small components should be evaluated for their impact on thermal efficiency.

What are masonry veneer anchors?

500

When brick veneer meets cast stone, this material is often placed between them to prevent cracks caused by differential movement.

What is a bond break?

500

CMU Walls can achieve a 4-hour fire rating when this material is used at the control joint location.

What is ceramic fiber?

500

This flashing accessory projects beyond the face of the wall so water drips clear instead of running down the veneer.

What is a drip edge?
