(a) Table 3.2.3.1.B. or Table 3.2.3.1.C. for an exposing building face conforming to Article 3.2.3.2. of a building or fire compartment that is not sprinklered, or

(b) Table 3.2.3.1.D. or Table 3.2.3.1.E. for an exposing building face conforming to Article 3.2.3.2. of a sprinklered fire compartment that is part of a building that is sprinklered in conformance with Section 3.2.

(2)  The area of the unprotected openings in an exposing building face shall be the aggregate area of unprotected openings expressed as a percentage of the area of the exposing building face in Table 3.2.3.1.B., Table 3.2.3.1.C., Table 3.2.3.1.D. or Table 3.2.3.1.E.

(3)  For the purpose of determining the type of construction and cladding and the fire-resistance rating of an exterior wall,

(a) the exposing building face shall be taken as the projection of the exterior wall onto a vertical plane located so that no portion of the exterior wall of the building or of a fire compartment, if the fire compartment complies with the requirements of Article 3.2.3.2., is between the vertical plane and the line to which the limiting distance is measured, and

(b) the area of unprotected openings shall be determined from Table 3.2.3.1.B., Table 3.2.3.1.C., Table 3.2.3.1.D. or Table 3.2.3.1.E.

(4)  For the purpose of determining the actual percentage of unprotected openings permitted in an exterior wall, the location of the exposing building face is permitted to be taken at a vertical plane located so that there are no unprotected openings between the vertical plane and the line to which the limiting distance is measured.

(6)  The distance between individual unprotected openings described in Sentence (5) that serve a single room or space described in Sentence (7) shall not be less than,

(a) 2 m measured horizontally where the unprotected openings are on the same exposing building face, or

(b) 2 m measured vertically where the unprotected openings both serve,

(i) the single room or space, or

(ii) another room or space on the same storey.

(7)  For the purpose of Sentence (6), “single room or space” means a room or space that,

(a) is not divided by a wall,

(b) is divided by,

(i) a wall that extends less than 1.5 m from the interior face of the exterior wall, or

(ii) a partial height wall, or

(c) consists of two or more stacked spaces that are on the same storey.

(8)  If a building has any storey that is not sprinklered and firefighting facilities cannot reach it within 10 min of the alarm being received, the required limiting distance shall be doubled.

(9)  If the surface temperature on the unexposed surface of a wall assembly exceeds the temperature limit of a standard fire test as permitted by Article 3.1.7.2., an allowance shall be made for the radiation from the hot unexposed wall surface by adding an equivalent area of unprotected opening to the area of actual openings as follows:

AC = A + (AF FEO)

where,

AC = corrected area of unprotected openings including actual and equivalent openings,

A = actual area of unprotected openings,

AF = area of exterior surface of the exposing building face, exclusive of openings, on which the temperature limit of the standard test is exceeded, and

(a) the actual area of unprotected openings, or

(b) the corrected area of unprotected openings.

(11)  The required limiting distance for an exposing building face is permitted to be measured to a point beyond the property line that is not the centre line of a street, lane or public thoroughfare if,

(a) the owners of the properties on which the limiting distance is measured and the municipality enter into an agreement in which such owners agree that,

(i) each owner covenants that, for the benefit of land owned by the other covenantors, the owner will not construct a building on his or her property unless the limiting distance for exposing building faces in respect of the proposed construction is measured in accordance with the agreement,

(ii) the covenants contained in the agreement are intended to run with the lands, and the agreement shall be binding on the parties and their respective heirs, executors, administrators, successors and assigns,

(iii) the agreement shall not be amended or deleted from title without the consent of the municipality, and

(iv) they will comply with such other conditions as the municipality considers necessary, including indemnification of the municipality by the other parties, and

(b) the agreement referred to in Clause (a) is registered against the title of the properties to which it applies.

(12)  Where an agreement referred to in Sentence (11) is registered against the title of a property, the limiting distance for exposing building faces shall be measured to the point referred to in the agreement.

(1)  Openings in a wall that has a limiting distance less than 1.2 m shall be protected by closures whose fire-protection rating is in conformance with the fire-resistance rating required for the wall.

(2)  Wired glass or glass block shall not be used for a closure referred to in Sentence (1).

3.2.3.6.  Combustible Projections

(1)  Except for a building containing one or two dwelling units only, combustible projections on the exterior of a wall that could expose an adjacent building to fire spread and are more than 1 m above ground level, including balconies, platforms, canopies and stairs, shall not be permitted within,

(a) 1.2 m of a property line or the centre line of a public way, or

(b) 2.4 m of a combustible projection on another building on the same property.

(2)  Where the exposing building face has a limiting distance of not more than 0.45 m, projecting roof soffits shall not be constructed above the exposing building face.

(3)  Where the exposing building face has a limiting distance of more than 0.45 m, the face of roof soffits above the exposing building face shall not project to less than 0.45 m from the property line.

(4)  Where roof soffits project to less than 1.2 m from the centre line of a lane or public thoroughfare or from an imaginary line between two buildings or fire compartments on the same property, they shall,

(a) have no openings, and

(b) be protected by,

(i) not less than 0.38 mm thick sheet steel,

(ii) unvented aluminum conforming to CAN/CGSB-93.2-M, “Prefinished Aluminum Siding, Soffits and Fascia, for Residential Use”,

(iii) not less than 12.7 mm thick gypsum soffit board or gypsum ceiling board installed according to CSA A82.31-M, “Gypsum Board Application”,

(iv) not less than 11 mm thick plywood,

(v) not less than 12.5 mm thick OSB or waferboard, or

(vi) not less than 11 mm thick lumber.

(5)  For buildings of combustible construction, materials installed to provide the required protection of soffits may be covered with a combustible or noncombustible finish material.

3.2.3.7.  Construction of Exposing Building Face

(1)  Except as provided in Sentences (3) and (4) and Articles 3.2.3.10. and 3.2.3.11, the fire-resistance rating, construction and cladding for exposing building faces of buildings or fire compartments shall comply with Table 3.2.3.7.

(2)  Reserved

(3)  Except as provided in Sentence (4), cladding for buildings or fire compartments where the maximum permitted area of unprotected openings is more than 10% of the exposing building face need not be noncombustible where the wall assembly complies with the requirements of Sentences 3.1.5.5.(1), (3) and (4) when tested in conformance with CAN/ULC-S134, “Fire Test of Exterior Wall Assemblies”.

(4)  Cladding for buildings or fire compartments where the maximum permitted area of unprotected openings is more than 25% but not more than 50% of the exposing building face need not be noncombustible where,

(a) the limiting distance is greater than 5 m,

(b) the building or fire compartment and all combustible attic or roof spaces are sprinklered,

(c) the cladding,

(i) conforms to Subsection 9.27.6., 9.27.7., 9.27.8., 9.27.9. or 9.27.10.,

(ii) is installed without furring members, or on furring not more than 25 mm thick, over gypsum sheathing at least 12.7 mm thick or over masonry, and

(iii) after conditioning in conformance with ASTM D 2898, “Accelerated Weathering of Fire-Retardant-Treated Wood for Fire Testing”, has a flame-spread rating not greater than 25 on the exterior face when tested in accordance with Sentence 3.1.12.1.(1), or

(d) the cladding,

(i) conforms to Subsection 9.27.12.,

(ii) is installed with or without furring members over gypsum sheathing at least 12.7 mm thick or over masonry,

(iii) has a flame-spread rating not greater than 25 when tested in accordance with Sentence 3.1.12.1.(2), and

(iv) does not exceed 2 mm in thickness exclusive of fasteners, joints and local reinforcements.

(5)  Where Table 3.2.3.7. permits an area of unprotected openings of more than 10% but not more than 25% of the exposing building face, the requirements for noncombustible cladding are waived for wall assemblies that comply with Article 3.1.5.5.

(6)  The construction requirements for the exposing building face that are listed in Table 3.2.3.7. shall be satisfied before the area of unprotected openings may be increased as permitted by Sentence 3.2.3.12.(1).

3.2.3.8.  Protection of Exterior Building Face

(1)  Except as permitted by Sentence (3) and in addition to the requirements of Sentence 3.2.3.7.(1) and where the maximum permitted area of unprotected openings is greater than 10% of the exposing building face, foamed plastic insulation used in an exterior wall of a building more than 3 storeys in building height shall be protected on its exterior surface by,

(a) concrete or masonry not less than 25 mm thick, or

(b) noncombustible material that complies with the criteria for testing and conditions of acceptance of Sentence (2) when tested in conformance with CAN/ULC-S101, “Fire Endurance Tests of Building Construction and Materials”.

(2)  The criteria for testing and the conditions of acceptance for a wall assembly to satisfy the requirements of Clause (1)(b) are that,

(a) the fire exposed area of the wall assembly shall be not less than 9.3 m2 and have no dimension less than 2.75 m,

(b) the exposed surface will include typical vertical and horizontal joints,

(c) the test shall be continued for not less than 15 min and the standard time/temperature curve of the referenced standard shall be followed,

(d) the noncombustible protective material will remain in place and no through openings will develop that are visible when viewed normal to the face of the material, and

(e) the noncombustible protective material will not disintegrate in a manner that would permit fire to propagate along the surface of the test assembly.

(3)  The requirements of Sentence (1) are waived for wall assemblies that comply with the requirements of Article 3.1.5.5.
