Insulation and Interior Inspection Section#1 Insulation and Ventilation Quiz#1

This study session covers the ASHI ®/CAHI Standards of Practice for inspecting insulation systems. It also covers a brief introduction to the Insulation inspection.

The estimated completion time is about thirty minutes.

Objectives
At the end of this Study Session, you should be able to:

• Identify three components that have to be observed during the insulation inspection.
• Identify two components that have to be reported as a result of your insulation inspection.
• Define in one sentence the terms insulation and vapor retarder.
• Describe in one sentence the implications of inadequate insulation.
• Describe in one sentence the implications of inadequate air/vapor barriers.
• Define degree-day in two sentences.
• Name two house systems that affect moisture control in houses.
• Name two kinds of house ventilation.

• Question 1

  Needs Grading

  	A vapour retarder is designed to...(Complete the sentence)
  	Selected Answer: restrict vapor diffusion. An air/vapor barrier restricts vapor diffusion and air leakage. Correct Answer:   Restrict vapour diffusion Response Feedback: [None Given]

• Question 2

  Needs Grading

  	Define degree-day.
  	Selected Answer: The average temperature for a day is subtracted from 65F. If the average temperature on a given day is 45F, there would be 20 degree-days attributed to that day. This calculation is done for each day of the heating season and the number of degree-days are added. The total provides the number of degree-days for that season.  Correct Answer: The average temperature for a day is subtracted from 65 degrees Fahrenheit, giving a number of degree days for that day (i.e. 65 degrees Fahrenheit - 45 degrees Fahrenheit = 20 degree days, if the average temperature is 45 degrees Fahrenheit). Response Feedback: [None Given]

• Question 3

  Needs Grading

  	Describe two functions of kitchen and bathroom venting systems.
  	Selected Answer: 1. To eliminate moisture, which may otherwise condense in wall system, causing damage.  2. To remove indoor air pollutants and draw an adequate supply of fresh air into the house.  Correct Answer:   1. To eliminate moisture 2. To remove indoor air pollutants and draw an adequate supply of fresh air into the house Response Feedback: [None Given]

• Question 4

  Needs Grading

  	Give four examples of unconditioned spaces.
  	Selected Answer: 1. Attic 2. Flat roof space 3. Knee wall areas 4. Crawlspace 5. Wall cavities Correct Answer:   1. Attic 2. Flat roof space 3. Knee wall areas 4. Crawlspace areas 5. Wall cavities Response Feedback: [None Given]

• Question 5

  Needs Grading

  	List three areas that have to be observed during the Insulation part of an inspection to the Standards.
  	Selected Answer: 1. Insulation and vapor retarders in unfinished areas 2. Ventilation of attics and foundation areas 3. Kitchen, bathroom, laundry and similar exhaust systems 4. Clothes dryer exhaust systems Correct Answer:   1. Insulation and vapour retarders in unfinished spaces 2. Ventilation of attics and foundation areas 3. Kitchen, bathroom and laundry ventilation systems Response Feedback: [None Given]

• Question 6

  Needs Grading

  	List two items that have to be described in your insulation inspection report.
  	Selected Answer: 1. Insulation and vapor retarders in unfinished areas.  2. Absence of insulation in unfinished spaces at conditioned surfaces. Correct Answer:   1. Insulation and vapour retarders in unfinished spaces 2. Absence of same in unfinished space at conditioned surfaces Response Feedback: [None Given]

• Question 7

  Needs Grading

  	List two items that you are not required to report on as part of your Insulation inspection.
  	Selected Answer: 1. Determinate indoor air quality 2. Determinate system adequacy or distribution balance Correct Answer:   1. Concealed insulation and vapour retarders 2. Venting equipment which is integral with household appliances Response Feedback: [None Given]

• Question 8

  Needs Grading

  	Name two house systems that affect moisture control in houses.
  	Selected Answer: 1. Air/vapor barriers 2. Ventilation Correct Answer:   1. Air/vapour barriers 2. Ventilation Response Feedback: [None Given]

• Question 9

  Needs Grading

  	Name two kinds of house ventilation.
  	Selected Answer: 1. One type flushes moisture from unconditioned spaces in the winter and flushes heat from these spaces in the summer.  2. Provides fresh air for the occupants of the home. Correct Answer:   1. Flushes moisture from unconditioned spaces in winter and heat from these spaces in summer 2. Provides fresh air for building occupants Response Feedback: [None Given]

• Question 10

  Needs Grading

  	The primary function of insulation is to...(Complete the sentence)
  	Selected Answer: control heat loss Correct Answer:   To control heat loss Response Feedback: [None Given]

• Question 11

  Needs Grading

  	What are the implications of an inadequate air/vapour barrier?
  	Selected Answer: heat loss Correct Answer:   Moisture may get into the building structure, causing damage. Response Feedback: [None Given]

• Question 12

  Needs Grading

  	What isd the function of insulation?
  	Selected Answer: The function of insulation is to control heat loss Correct Answer:   To control heat loss. 1. In cold climates, it keeps the house warm. 2. In hot climates, it keeps the house cool. Response Feedback: [None Given]
