12.3.2.4. — Insulation of Foundation Walls
(1) Sentence (2) applies to construction for which a permit has been applied for before January 1, 2009.
(2) Foundation walls enclosing heated space shall be insulated from the underside of the subfloor to not less than 600 mm below the adjacent exterior ground level.
(3) Sentence (4) applies to construction for which a permit has been applied for after December 31, 2008.
(4) Foundation walls enclosing heated space shall be insulated from the underside of the subfloor to not more than 380 mm above the finished floor level of the basement.
(5) The insulation required by Sentences (2) and (4) may be provided by a system installed,
(a) on the interior of the foundation wall,
(b) on the exterior face of the foundation wall, or
(c) partially on the interior and partially on the exterior, provided the thermal performance of the system is equivalent to that permitted in Clauses (a) or (b).
(6) Insulation around concrete slabs-on-ground shall extend not less than 600 mm below exterior ground level.
(7) The minimum RSI value required in Table 12.3.2.1. for the perimeter of a slab-on-ground is permitted to be reduced by 50% if the underside of the entire slab-on-ground is insulated.
(8) If a foundation wall is constructed of hollow masonry units, one or more of the following shall be used to control convection currents in the core spaces,
(a) filling the core spaces,
(b) at least one row of semi-solid blocks at or below grade, or
(c) other similar methods.
(9) Masonry walls of hollow units that penetrate the ceiling shall be sealed at or near the ceiling adjacent to the roof space to prevent air within the voids from entering the attic or roof space by,
(a) capping with masonry units without voids, or
(b) installation of flashing material extending across the full width of the masonry.
Editor's note
As filed in O. Reg. 350/06, Clause (5)(c) of Article 12.3.2.4. closes 'equivalent to that permitted in Clauses (a) or (b)' with the plural 'Clauses'; the current e-Laws consolidation renders the singular 'Clause (a) or (b)', with no amending regulation making the change. Both forms refer to the same two clauses, and this map preserves the wording as filed.
