Question 1

Why can the infill walls not be used in contemporary construction?

Accepted Answer

Because of the current energy code requirement that the entire exterior be continuously insulated.

Question 2

Using sketches and notes, explain the important features of a drainage- type exterior wall.

Accepted Answer

A drainage-type exterior wall is designed to effectively manage water and moisture to prevent damage to the building structure. The important features of a drainage-type exterior wall include:

1. Weather-resistant barrier: A drainage-type exterior wall includes a weather-resistant barrier, such as a house wrap or building paper, to protect the building from moisture infiltration.

2. Drainage plane: The wall system includes a drainage plane, which is a space or material that allows water to drain away from the wall assembly. This can include a drainage mat or a ventilated air space.

3. Flashing: Properly installed flashing is essential for a drainage-type exterior wall to direct water away from vulnerable areas, such as windows, doors, and other penetrations.

4. Weep holes: These small openings are incorporated into the wall system to allow any trapped water to drain out of the wall assembly.

5. Durable cladding: The exterior finish, such as siding or stucco, should be durable and properly installed to provide an additional layer of protection against moisture.

6. Sloped design: The wall should be designed with a slight slope to encourage water to drain away from the building rather than collecting against the wall.

These features work together to create a drainage-type exterior wall that effectively manages water and moisture, protecting the building from potential damage. Proper installation and maintenance of these features are essential for the long-term performance of the wall system.
