1. give two reasons why carpenters install doors and windows with their tops at the same height.
2. what are two alternative methods to construct a header for large window openings without decreasing the length of the cripple studs?
3. why is a story pole often used when laying out wall framing?
4. after corner posts are plumb and top plates are doubled, how is a wall straightened?
5. what are four major benefits of advanced framing?
6. name two different uses for housewrap.

Explanation:

1. Aesthetic and functionality: Aesthetically, it creates a more uniform and pleasing - to - the - eye appearance. Functionally, it simplifies measuring and installing trim and other finishing materials.
2. Use of engineered lumber or multiple - piece headers: Engineered lumber can provide more strength without reducing cripple stud length. Multiple - piece headers made of standard lumber can be stacked to achieve the required strength.
3. Consistency and accuracy: A story pole ensures consistent placement of studs, headers, and other components in wall framing, reducing errors.
4. Using a straightedge and adjusting studs: A straightedge is placed along the wall, and any out - of - line studs are adjusted or shimmed to straighten the wall.
5. Material savings, faster construction, better energy efficiency, and increased structural integrity: Advanced framing uses less lumber, speeds up construction, improves insulation due to fewer thermal bridges, and can enhance the overall strength of the building.
6. Weather protection and air barrier: Housewrap acts as a barrier against rain and moisture, and also helps in controlling air infiltration and exfiltration.

Answer:

1. Aesthetic appeal and ease of finishing installation.
2. Using engineered lumber; creating multiple - piece headers.
3. To ensure consistent and accurate placement of framing components.
4. By using a straightedge and adjusting studs.
5. Material savings, faster construction, better energy efficiency, increased structural integrity.
6. Weather protection, air barrier.
