1 Scope

1.1 

This Supplement is for use in conjunction with AAMA/WDMA/CSA 101/I.S.2/A440-17 and contains additional requirements for Canada.

1.2 

This Supplement provides simplified methods to calculate the minimum performance levels for resistance to water penetration, wind loads, and snow loads for fenestration products on buildings in Canada.

This Supplement specifies two different methods for calculating the minimum performance levels for resistance to wind loads and snow loads:

Method 1: the simplified procedures specified in Clause 4.2.

Method 2: compliance with the more detailed procedures specified by the structural commentary requirements of the National Building Code of Canada (NBCC).

Note: The edition of the NBCC in effect can vary by jurisdiction.

In some cases, the simplified procedure specified in Clause 4.2 of this Supplement can result in higher values than those attained by using the procedures in the building code.

The simplified procedure to calculate specified wind load in Clause 4.2.2 applies only to buildings on level terrain, having a slope no greater than 1:10. For buildings that do not meet this criteria (e.g., buildings on steeper slopes, hills, or escarpments) wind load values are calculated in accordance with the structural commentary requirements of the NBCC.

The simplified procedure to calculate specified snow load in Clause 4.2.4 applies only to small, simple, light-frame buildings. For buildings that do not meet this criteria, snow load values are calculated in accordance with the structural commentary requirements of the NBCC.

Calculating wind load value using Tables 1 to 5 in Clause 4.2 can result in a higher wind load value than if the calculation is done using the formula in Clause 4.2. The higher wind load can result in a higher performance grade product being specified than is required by the applicable building code.

 

1.3

This supplement introduces the issue of Climate Change, and the associated effects on fenestration in buildings.  It is anticipated that fenestration designers will need to incorporate changes in climate loads resulting from climate change into the fenestration product design.  Annex B – “Climate Change effects on the durability of fenestration products” provides some information on this topic for consideration by designers.  As information on climate loads evolves, so too will this standard and the information available to designers.

 

 

1.4 

In this Supplement, “shall” is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the publication; “should” is used to express a recommendation or that which is advised but not required; and “may” is used to express an option or that which is permissible within the limits of the publication.

Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material.

Notes to tables and figures are considered part of the table or figure and may be written as requirements.

Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.

1.2

This Standard specifies both measurement and calculation methods for establishing the following fenestration system properties for both residential and commercial applications:

(a)   overall coefficient of heat transfer (U-factor);

(b)   solar heat gain coefficient (SHGC); and

(c)   visible transmittance (VT).

This Standard also specifies measurement methods for establishing the Temperature Index (I) for fenestration systems for both residential and commercial applications.

Note: The fenestration properties established in accordance with this Standard are for specific indoor and outdoor conditions and will vary slightly under actual conditions. The values obtained by the methods specified in this Standard are considered to provide an acceptable basis for comparing performance in use.

1.3

1.3.1

This Standard specifies a method for determining an energy performance rating for vertical fenestration systems, under heating conditions, for use in low-rise residential applications. The Energy Rating (ER) includes factors for

(a)   solar heat gain;

(b)   heat loss by conduction, radiation, and convection; and

(c)   heat loss by air leakage.

1.3.2

The ER allows for a comparison of different fenestration systems on the basis of their effect on the energy supplied annually by the heating system. The ER calculation assumes vertical installation in low-rise residential buildings and is based on average conditions for

(a)   incident solar radiation on fenestration systems facing the four cardinal compass directions (north, east, south, and west); and

(b)   representative climate zones in Canada.

1.3.3

The ER should not be used to rate

(a)   any sloped glazing (residential or commercial); or

(b)   fenestration products that will be installed in commercial, industrial, or high-rise residential buildings.

1.4

CSA A440.3 is a user guide to this Standard. It provides guidance on determining

(a)   a specific Energy Rating (ERS) for particular locations, orientations, and vertical fenestration system sizes; and

(b)   an ER for residential cooling (ERC).

 

1.5

This supplement introduces the issue of Climate Change, and the associated effects on fenestration in buildings.  It is anticipated that fenestration designers will need to incorporate changes in climate loads resulting from climate change into the fenestration product design.  It is also anticipated that adjustments will be needed to installation detailing.  Annex B – “Climate Change effects on the durability of fenestration products” provides some information on this topic for consideration by building design professionals, authorities having jurisdiction and installers.  As information on climate change  evolves, so too will the requirements of this standard.

 

1.6

This Standard does not apply to

(a)    fixed glazing cast into precast concrete panels;

(b)    revolving doors;

(c)    doors intended for indoor use; and

(d)    storm doors.

Note: While these products have not been considered in the development of this Standard, simulation procedures given in the Standard may be used to evaluate the U-factor and the SHGC of these products.

1.7

This Standard does not address the retention of thermal and optical properties and airtightness by fenestration systems over time and under conditions of use.

1.8

In CSA Standards, “shall” is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the standard; “should” is used to express a recommendation or that which is advised but not required; and “may” is used to express an option or that which is permissible within the limits of the standard; and “can” is used to express possibility or capability.

Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material.

Notes to tables and figures are considered part of the table or figure and may be written as requirements. Legends to equations and figures are considered requirements.

Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.

1 Scope

1.1 

This Standard sets forth methods for both new installation and replacement installation of factory assembled windows, exterior doors, and skylights that are intended for installation in low-rise buildings and buildings used primarily for, but not limited to, residential occupancy where the windows, doors, and skylights (including window wall) are R, LC, or CW class within the application of AAMA/WDMA/CSA 101/I.S.2/A440.

Note: The effectiveness, safety, and durability of installed fenestration products depend on the choice and quality of materials and design, adequate assembly, the support system, and proper installation. Improper installation of fenestration products might reduce their effectiveness, including excessive condensation; unacceptably high levels of air, water, and sound leakage; and deterioration of the wall and roof systems into which they are installed.

1.2 

This Standard provides minimum requirements for the installation of fenestration products including windows, doors, and skylights. This Standard addresses issues that could compromise the performance of the fenestration product as established by testing to the requirements of AAMA/WDMA/CSA 101/I.S.2/A440. Where installation methods are not specifically addressed in this Standard or in the installation instructions of the manufacturer of a fenestration product, a design professional should be consulted for a solution consistent with the intent of the minimum requirements and principles in this Standard.

1.3 

This supplement introduces the issue of Climate Change, and the associated effects on fenestration in buildings.  It is anticipated that fenestration designers will need to incorporate changes in climate loads resulting from climate change into the fenestration product design.  It is also anticipated that adjustments will be needed to installation detailing.  Annex H – “Climate Change effects on the durability of fenestration products” provides some information on this topic for consideration by building design professionals, authorities having jurisdiction and installers.  As information on climate change evolves, so too will the requirements of this standard.

The application of this Standard requires a working knowledge of applicable federal, provincial, and local (municipal) building codes and regulations specifically concerning, but not limited to, required means of egress and requirements for safety glazing.

1.4 

This Standard does not apply to the

a) selection of fenestration products for a given application;

b) selection of other products for use in the installation;

c) installation of storm windows or storm doors;

d) maintenance of installed fenestration products;

e) rebuilding of fenestration products; or

f) fabrication of fenestration products, whether such fabrication takes place in a factory or at the installation site.

Note: For product selection information, see CSA A440S1.

1.5 

This Standard does not purport to address all of the safety problems associated with its use. It does not set out requirements relating to the safety of the person installing the units. It is the responsibility of the installer to obtain necessary health and safety training and to follow proper procedures for safe handling and application of installation materials and fenestration products.

1.6 

This Standard assumes that its users are familiar with the terminology, procedures, and requirements of good building practice. Some requirements and guidance are included in this Standard, but the installer should also refer to information available from installation material and fenestration product manufacturers.

1.7 

This Standard does not address the qualifications and skills that an installer should possess. It assumes familiarity with the fundamentals of low-rise building construction in Canada as described in Division B, Part 9 of the NBC and of installation techniques for fenestration products normally available in Canada. Although guidance is provided in the manner of installation of fenestration products, it is not a training manual.

1.8 

In this Standard, “shall” is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the standard; “should” is used to express a recommendation or that which is advised but not required; and “may” is used to express an option or that which is permissible within the limits of the Standard.

Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material.

Notes to tables and figures are considered part of the table or figure and may be written as requirements.

Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.

1.9 

The values given in SI units are the units of record for the purposes of this Standard. The values given in parentheses are for information and comparison only.
