The estimated completion time for this study session is ninety minutes.
Objectives
At the end of this study session, you should be able to:
At the end of this study session, you should be able to:
- Sate as least three precautions you should take when inspecting attics.
- List six other house system components you'll be typically looking at when in the attic.
- List twenty-six insulation and ventilation related problems (and their implications) you may find in attics.
- Describe in one sentence the inspection strategy for each of the above problems.
Question 1
How is heat loss and air leakage controlled around whole-house fans?Selected Answer: Using a insulated cover that can be placed over the fan in the attic during the winter montsh.Correct Answer: With an insulated coverResponse Feedback: [None Given] Question 2
How should insulation be handled around masonry chimneys?Selected Answer: Masonry chimneys should have non-combustible insulation surrounding them.Correct Answer: Masonry chimneys should only have non-combustible insulation surrounding them.Response Feedback: [None Given] Question 3
How should insulation be handled around metal vents?Selected Answer: Metal vents should have no insulation around them for a distance of one to two inches, depending on the type of the vent or chimney.Correct Answer: Vent is contained in a boxed-in area to keep insulation away.Response Feedback: [None Given] Question 4
List at least three things that may make attics dangerous.Selected Answer: 1. Covered with insulation2. Hatch is difficult to open3. Stairs may not be well maintainedCorrect Answer: Fall through the ceiling Electric shock Irritate lungs, eyes, and skinResponse Feedback: [None Given] Question 5
List at least two safety concerns related to pull-down stairs.Selected Answer: 1. They may come down very quickly if mechanical components are loose or broken.2. Treads or stringers may be loose or broken.Correct Answer: Mechanical components loose or broken when pulling down Treads or stringers may be loose or brokenResponse Feedback: [None Given] Question 6
List five attic staircase problems and the implications of each.Selected Answer: 1. Inadequate insulation and weather stripping2. Stair rise, run and tread problems3. Handrail and guardrail problems4. Lighting problems5. Headroom problemsCorrect Answer: Inadequate insulation or weatherstripping / Heat loss, air leakage Stair rise, run and tread problems / Safety concerns Handrail and guardrail problems / Safety concerns Lighting problems / Safety concerns Headroom problems / Safety concernsResponse Feedback: [None Given] Question 7
List four common access hatch problems and the implications of each.Selected Answer: 1. Not insulated2. Weather-stripped3. Missing4. InaccessibleCorrect Answer: Not insulated / Results in heat loss Not weather-stripped / Results in heat loss and air leakage Missing / Limits inspection Inaccessible / Limits inspectionResponse Feedback: [None Given] Question 8
List six other house systems that may have components to inspect while in the attic.Selected Answer: 1. Roofing2. Structure3. Electrical4. Heating5. Air-conditioning and heat pump6. PlumbingCorrect Answer: Roofing Structure Electrical Heating Air conditioning or heat pump systems PlumbingResponse Feedback: [None Given] Question 9
List three common problems with roof vents and their implications.Selected Answer: 1. Venting missing or inadequate2. Venting obstructed at soffit or roof vents3. Snow or wet spots below roof ventsCorrect Answer: Problems: 1. Birds? nests 2. Mechanical damage 3. Undersized openings Implications: 1. Inadequate venting 2. Mold/mildew/rot from condensationResponse Feedback: [None Given] Question 10
List three common pull-down stair problems and the implications of each.Selected Answer: 1. Stairs coming down too fast2. Stairs not solid and stable3. Stairs not insulatedCorrect Answer: Stairs come down too fast / Safety or dangerous Not solid and stable / Safety or dangerous Not insulated / Heat loss, air leakageResponse Feedback: [None Given] Question 11
List three possible concerns with turbine vents.Selected Answer: 1. Obstructed2. Bent3. CorrodedCorrect Answer: 1. No ventilation on calm days 2. Too much ventilation on windy days 3. Noisy or seizedResponse Feedback: [None Given] Question 12
Should power vents be operating in the winter? Why or why not?Selected Answer: No. It would depressurize attic and draw warm, moist house air into roof spacesCorrect Answer: No, they can depressurize the attic, increasing heat loss.Response Feedback: [None Given] Question 13
Under what circumstances should insulation cover recessed lights? What is one inspection strategy to help identify recessed lights while in the attic?Selected Answer: If the type has double shell with an air space between to help cool the fixture.Look for a double shell on the fixture. Designation that includes the letters IC indicating appropriate for use in a insulated ceiling.Correct Answer: 1. Only if lights are proper type, or installed in drywall boxes 2. Look for double shell, or ?IC? stampResponse Feedback: [None Given] Question 14
What are the implications of air/vapour barriers that are missing or incomplete?Selected Answer: Increased air leakage and possible rot damage from condensation are the implications of a missing air/vapor barrier.Correct Answer: 1. Air leakage 2. Rot damage 3. Insulation gets wet from condensationResponse Feedback: [None Given] Question 15
What are the implications of insulation that is only two inches thick, wet, compressed, interrupted by gaps or voids, or missing?Selected Answer: 1. Increased heat loss2. Amount of moisture is siginificantCorrect Answer: Two inches thick / Heat loss, ice damming Wet / Won?t work well, damage to finishes Gaps and voids / Localized heat loss Compressed / Reduced R-value Missing / Heat loss, ice dammingResponse Feedback: [None Given] Question 16
What is suggested by mold, mildew or rot on rafters and sheathing?Selected Answer: Weakened structural performances and ultimate failure of the roof structureCorrect Answer: An exhaust fan dumping warm, moist air directly into the atticResponse Feedback: [None Given] Question 17
What is suggested by snow on attic insulation below roof vents?Selected Answer: Water damageCorrect Answer: If soffit venting is missing, rain and snow may actually be drawn into the roof vents.Response Feedback: [None Given] Question 18
What safety issues are there surrounding permanent staircases to attics?Selected Answer: 1. Not uniformly, adequate tread width2. Not enough rise3. Not enough headroom4. No handrails5. No guardrail around the topCorrect Answer: Should be uniform with adequate tread width and rise Headroom should be adequate Handrails and a guardrail should be at the top Adequate lightingResponse Feedback: [None Given] Question 19
What should you wear when inspecting attics? (List three things.)Selected Answer: mask and gogglesCorrect Answer: Mask Goggles Long sleeves with tight cuffsResponse Feedback: [None Given] Question 20
What two things should you be looking for on ducts in attics?Selected Answer: 1. Leaking or disconnected2. Insulation missing or looseCorrect Answer: 1. Insulation 2. Air/vapour barrierResponse Feedback: [None Given] Question 21
Will you ever see walls in attics? Where? Should these be insulated?Selected Answer: Knee wall. They should be insulated.Correct Answer: 1. Walls indicate skylights or light wells 2. Yes, should be insulatedResponse Feedback: [None Given]
