Insufficient Insulation

Article Number

8.7

Condition

INSUFFICIENT INSULATION

Acceptable Performance/Condition

Performance/Condition:Insulation shall be installed in accordance with the Building Code.

Warranty

One-Year - Work and Materials. Two-Year - Ontario Building Code Health & Safety Violations

Action

Insulation levels not meeting the acceptable condition shall be repaired.

Remarks

Several factors affect living space temperatures: a) Proper installation of insulation shall include correct placement behind electrical boxes, backing studs, corner framing and wiring, and around window and door openings. b) Directional orientation - north-facing rooms are generally cooler than south-facing rooms. c) Windows - glass has little insulating value and allows more heat to escape from the room. d) Rooms over garages - have insulated floors that lose heat to the unheated garage below. e) Airflow - free airflow from the supply outlet in a room to a return inlet or undercut door is essential. Generally, a minimum 25 mm space under interior doors above the finished floor covering should be provided.
