Humber/Ontario Real Estate Course 3 Exam Practice

Which of the following is NOT a criterion for Canadian Standards Association (CSA) window ratings?

1. Air Tightness

2. Energy Efficiency

3. Noise Resistance

4. UV Protection

5. Water Tightness

6. Wind Resistance

The correct answer is: Noise Resistance

The Canadian Standards Association (CSA) window ratings are designed to assess various performance aspects of windows, ensuring that they meet specific safety and quality standards. These criteria include factors crucial for the window's overall functionality and efficiency. Air tightness evaluates how well a window prevents air from leaking, which affects energy consumption and comfort. Energy efficiency measures how effectively windows contribute to a building's thermal performance and overall energy savings. Water tightness is crucial for preventing water infiltration, which protects the integrity of the building. Wind resistance assesses the window's ability to withstand pressure from wind loads, an essential feature for ensuring structural safety. UV protection, although important for interior comfort and protection against fading, is not a formal rating criterion in the CSA window assessment. Noise resistance, while valuable for enhancing indoor acoustic comfort, is not included as a specific criterion for CSA window ratings. Instead, these ratings focus on physical characteristics like airtightness and structural integrity rather than sound mitigation, which may fall under other standards or categories but does not directly impact structural performance assessments by CSA. Thus, noise resistance is the correct answer, as it does not align with the primary performance metrics employed in the CSA's window rating criteria.
