About this Guide, The Illustrated Guide to R22 Effective Walls in Residential Construction in British Columbia is published by BC Housing This. guide consolidates information on above and below grade wall assemblies for low and mid rise buildings that are capable. of achieving R 22 or greater effective thermal performance The guide is intended to be an industry utility and government. resource with respect to meeting this thermal performance level while not compromising other aspects of building enclosure. performance including moisture management air leakage and durability. This edition of the guide has a shift in focus from the original guide and now includes information that applies to low rise. detached and semi detached homes row houses townhomes and multi unit residential buildings up to six storeys within British. Columbia While this guide provides general guidance on assembly selection and key considerations it does not provide extensive. information on detailing of the assemblies at transitions and penetrations The Additional Resources section on page 53. contains a list of various other guides that provide extensive information on the design and construction of high performance. building enclosure assemblies Although the guide generally focuses on wood frame concrete and steel frame walls that use. traditional construction methods some guidance is included for other less common wall types. It is important to note that each building and construction project is different and each present unique challenges This guide. provides an overview of assemblies that can meet higher thermal performance targets but it is likely that the various methods. shown will need to be modified to accommodate variations in each project Additionally alternative wall assemblies exist that are. beyond the scope of this guide, Disclaimer, This guide is provided for general information except where noted The greatest care has been taken to confirm the accuracy of. the information contained herein However the authors funders publisher and other contributors assume no liability for any. damage injury loss or expense that may be incurred or suffered as a result of the use of this publication including products. building techniques or practices The views expressed herein do not necessarily represent those of any individual contributor BC.

environments It comprises various elements including roofs above grade walls windows doors skylights below grade walls. and floors which in combination must control water air heat water vapour fire smoke and sound Additionally the enclosure is. an aesthetic element of the building, To perform these functions building assemblies may use a series of. layers each intended to serve one or multiple functions within the. building enclosure As an example for an above grade wood frame. wall cladding is typically installed to provide the aesthetic exterior. finish as well as the primary water shedding surface A water resistive. barrier WRB is installed inboard of the cladding as a secondary barrier. to moisture to prevent water ingress and a drainage gap is installed. between the cladding and WRB to allow drainage of water which. penetrates past the cladding This approach is commonly referred to. as a rainscreen wall assembly Insulation is installed to control the flow. of heat i e energy transfer through the enclosure and an air barrier. is installed to control bulk air movement through the wall A vapour. barrier is also installed to control diffusion of water vapour through the. wall assembly and while typically a very impermeable material is used. for this function i e Type 1 vapour barriers less than 6 ng s m Pa. more permeable materials can also fulfill this function i e Type 2. vapour barriers less than 60 ng s m Pa and smart vapour retarders Plan View. In many cases these functions can be provided in combination by a. single layer within the assembly for example the WRB and air barrier Water Shedding Surface. may both be provided by the sheathing membrane In concrete wall Water Resistive Barrier. Air Barrier, assemblies any number of these barriers may be provided by the Vapour Retarder. concrete itself The position of these different elements of the enclosure. Thermal Insulation, assembly and appropriate detailing of the building enclosure systems at. transitions and penetrations is fundamental to their performance. This guide focuses on wall assemblies that can achieve an effective thermal performance of approximately R 22 R 21 86 RSI. 3 85 while still meeting the other performance requirements for enclosure assemblies These wall assemblies help to reduce. the transmission of heat energy through the building enclosure and consequently reduce the heating and cooling loads of the. building and the overall building energy consumption. BC Building Code BCBC and Vancouver Building By law VBBL Compliance In many cases this guide indicates best practices. with respect to air vapour and moisture management rather than minimum requirements as specified by relevant building. regulations This approach is intended to promote the construction of effective and durable assemblies Furthermore in some cases. the guide identifies materials assemblies or practices for which a registered professional B C architect or engineer may be required. by the Code and or the authority having jurisdiction to indicate compliance with relevant building regulations Relevant building. regulations should be reviewed and complied with for each project. Illustrated Guide R22 Effective Walls in Residential Construction in British Columbia 5. 1 Introduction, R value Calculations, The thermal resistance of building assemblies is commonly indicated using R value provided in imperial units of. ft F hr Btu and can also be provided as RSI value in metric units of m K W All R values in this guide are provided in imperial. units The higher the R value the better the thermal performance U values are another way of describing heat flow through a. wall and are the inverse of R values The lower the U value the better the thermal performance. RSI 1 0 m K W R 5 678 ft F hr Btu R 1 U, For low rise residential construction R values can be calculated according to Section 9 36 of the British Columbia Building Code.
BCBC This section specifies that R values are to be calculated using the Isothermal Planes method The R value of layers of the. wall assemblies which include multiple components such as insulated stud walls should be calculated using the Parallel Paths. method i e area weighted U value calculation An example R value calculation for a split insulation wood frame wall assembly is. shown below, 3 4 Ventilated Air Space neglects furring.

R values RSI values are provided in the appendix Section A9 36 2 4 of. 2x6 Wood Framing, the BCBC For all calculations in this guide a 23 framing factor was used. corresponding with standard framing practices for 16 spaced studs Part. 9 of the BCBC does not require accounting of thermal bridging through. fasteners or brick ties or other penetrating elements such as pipes ducts. shelf angles anchors and ties and minor structural members that must. partially or completely penetrate the building enclosure to perform their. AF 23 Framing AI 77 Insulation intended function Major penetrations such as balconies beams and. RF R 6 8 RI R 19 columns do not need to be included as long as they form less than 2. 100 100 of the gross wall area and the surrounding insulation is installed tight. AF AI 23 77 against the penetrating element Continuous cladding supports such as. R 13 4 strapping which penetrates the insulation should be accounted for. 6 Illustrated Guide R22 Effective Walls in Residential Construction in British Columbia. 1 Introduction, Wall Assemblies in Non Part 9 Residential Buildings. Requirements for Calculations, For non Part 9 residential buildings calculation of the thermal performance of the wall assembly may require more effort beyond. the minimum code requirements of Part 9 36 of the BCBC The heat loss of potentially significant thermal bridges like concrete. floor slabs mechanical service penetrations and large built up structural wood elements should be accounted for in the thermal. calculations Regular penetrations like clips or fasteners through exterior insulation should also be accounted for Both the. American Society of Heating Refrigerating and Air Conditioning Engineers ASHRAE standard 90 1 and the National Energy Code. of Canada for Buildings NECB provide guidance on accounting for thermal bridging in effective R value calculations and the. ASHRAE Handbook Fundamentals provides specific guidance for various calculation methods Appropriate methods include. hand calculations thermal modelling and even laboratory testing See also the Building Envelope Thermal Bridging Guide see. Additional Resources on page 53 A registered professional should be consulted with and may be required by the authority. having jurisdiction for the design and calculation of the effective R value of the wall assemblies in a non .
