ASHI Interiors, Insulation & Ventilation 3

Question 1

An ASHI inspector tests a bedroom window and finds it cannot be opened. From a life-safety perspective, what is the PRIMARY concern?

Accepted Answer

Loss of emergency egress in case of fire

Answer

Sleeping rooms must have at least one operable window or door for emergency egress; a window that cannot open eliminates this required escape route in a fire.

Question 2

What does a home inspector look for when assessing the R-value adequacy of wall insulation without destructive testing?

Accepted Answer

Check for visible gaps, compression, or moisture damage around outlets and switches

Answer

Inspectors can remove outlet cover plates to observe insulation presence, thickness, and condition in wall cavities as a non-destructive indicator of insulation quality.

Question 3

Which ventilation system is MOST effective at maintaining good indoor air quality in a very tight, well-sealed modern home?

Accepted Answer

Mechanical balanced ventilation such as an HRV or ERV

Answer

A Heat Recovery Ventilator (HRV) or Energy Recovery Ventilator (ERV) provides continuous controlled fresh air exchange while recovering energy, making it ideal for tight homes.

Question 4

A home inspector notices that fiberglass batt insulation in the attic is compressed under heavy storage boxes. What is the effect on insulation performance?

Accepted Answer

Compression reduces the air pockets and significantly lowers R-value

Answer

Fiberglass batts rely on trapped air pockets for their thermal resistance; compression eliminates these air spaces and can reduce the effective R-value by 50% or more.

Question 5

An inspector finds that bathroom exhaust fans duct into the attic space rather than to the exterior. What is the MAIN deficiency?

Accepted Answer

Moisture-laden air dumped into the attic promotes mold and rot

Answer

Bathroom exhaust fans must terminate outside the building; venting into the attic deposits warm, humid air that condenses on cold surfaces, promoting mold growth and wood decay.
