12.3.3.3. — Thermal Resistance

(1) Except as provided in Articles 12.3.3.4. to 12.3.3.8., and except for doors, windows, skylights and other closures, the thermal resistance of each building assembly through any portion that does not include framing or furring shall conform to Table 12.3.3.3.

Editor's note

The note to Table 12.3.3.3. is reproduced here as filed in O. Reg. 350/06. The consolidated e-Laws text applies editorial formatting changes that were not enacted by any regulation; this map preserves the note as filed. The differences are: the heading "Notes to Table 12.3.3.3:" is in regular weight as filed and is rendered in bold on e-Laws, which also adds a trailing period to the table number ("12.3.3.3."); and the note marker "(1)" is plain text as filed and is rendered as a superscript on e-Laws.
