reduced to not less than RSI 1.61 if,
(a) the thermal resistance of insulation for the exposed roof or ceiling required in
Table 10.3.2.1. is increased by an amount equivalent to the reduction permitted
in this Sentence, and
(b) for log walls, the logs have tongue-and-groove or splined joints.
(3) Where milled log walls are installed, the thermal resistance value in Sentence (1) for
the total wall assembly does not apply if,
(a) the mean thickness of each log is not less than 150 mm,
(b) the thermal resistance of insulation for the exposed roof or ceiling required in
Table 10.3.2.1. is increased by RSI 0.53, and
(c) the logs have tongue-and-groove or splined joints.
10.3.3. Thermal Design for Buildings of Residential Occupancy Within the Scope of
10.3.3.1. Application (1) This Subsection applies to the thermal design of buildings to which Clause
10.2.1.1.(2)(b) applies. 10.3.3.2. General Requirements
(1) The materials for, and the installation of, thermal insulation, air barrier and vapour
barrier protection shall conform to Section 9.25.
(2) Foamed plastic thermal insulation shall be protected as described in Article
9.10.17.10.
(3) Crawl spaces shall conform to Section 9.18.
(4) Roof spaces shall conform to Section 9.19.
(5) Ventilation requirements shall conform to Section 9.32.
(6) Heating and air-conditioning requirements shall conform to Section 9.33.
10.3.3.3. Thermal Resistance
(1) Except as provided in Articles 10.3.3.4. to 10.3.3.8., 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
Table 10.3.3.3.

1. ICF walls and walls with cavities filled with low density open cell spray foam insulation provide an effective insulating
value. Walls of this construction have inherently effective air barriers and minimal thermal bridging characteristics. 2. This value may be reduced to R 4 at the thermal break between the slab and wall.
3. Spray foam insulation products provide an effective insulating value. This type of insulation product has inherently an
Table 10.3.3.3. replaced: N.S. Reg. 96/2010.

unless it can be shown that the heat flow is not greater than the heat flow through a
wood frame assembly of the same thickness.
