Humber/Ontario Real Estate Course 4 Exam Practice

Which material was commonly used for joists in older homes?

1. Concrete.

2. Plywood.

3. Metal beams.

4. Bricks.

5. Glass-fiber plastic.

6. Compressed straw.

The correct answer is: Plywood.

Plywood was indeed commonly used for joists in older homes, particularly in the mid to late 20th century as part of the framing system. It provided strength and stability while being relatively lightweight and easy to work with. Other materials like concrete and metal beams are more often associated with commercial construction and modern homebuilding, rather than older residential structures. Bricks are primarily used for walls or foundations rather than as joists, while glass-fiber plastic and compressed straw have not been traditional choices in residential framing due to their properties and structural limitations.
