4 Understanding Window Thermal Performance Units of Measure U metric, U imperial & R Value The relationship between U metric and U imperial is a simple division by Similar function as centimeters to inches. The U value is the inverse of the R value 1/U or 1/R How to Convert U metric value to R value example: U metric must first be converted to U imperial then divided 1 by the U imperial value Example 1.4 U metric / = 0.25 U imperial then 1/0.25 = 4 or R4 Or, just Google it.

6 NAFS North American Fenestration Standard Fenestration means openings in the walls of a structure. The word comes from the Latin word fenestra ("window"). Wikipedia Fenestration includes windows, doors, louvres, vents, wall panels, skylights, storefronts, curtain walls, and slope glazed systems.

7 What is the NAFS window standard? A document developed by the American Architectural Manufactures Association (AAMA) Window & Door Manufactures Association (WDMA) Canadian Standards Association (CSA) Why do we have to follow it? Referenced in the 2010 National Building Code (Model Code) Referenced in the 2012 BC Building Code Referenced in the 2014 Vancouver Building Bylaw

8 Standards in the BC Building Code 2006 BC Building Code Single Family; Part Windows shall conform to CAN/CSA A440, Windows and CAN/CSA A440.1 User Selection Guide. Multifamily; Part CAN/CSA A440, Windows and CAN/CSA A440.1 User Selection Guide BC Building Code Single Family; Part Windows, doors and skylights shall conform to AAMA/WDMA.CSA 101.I.S.2/A440, NAFS (Harmonized Standard) and Canadian Supplement to NAFS. Multifamily; Part Windows, doors and skylights shall conform to AAMA/WDMA.CSA 101.I.S.2/A440, NAFS (Harmonized Standard) and Canadian Supplement to NAFS.

10 Replacement Windows

11 Top 5 Reasons Homeowners want new windows? 1. I m tired of dealing with condensation. 2. I want to reduce my heating bills. 3. Improve comfort. 4. My neighbours replaced their windows. 5. New windows will increase my property value.

12 How do we proceed from here? 1. Understand the buildings exposure. 2. Understand the condition of the building. 3. Understand the most appropriate installation method. 4. Select the right features and options.

14 Building Assessment WINDOW REPLACEMENT ON AN EXISTING BUILDING 1. Understand the type of building you are going to be working with. 2. Determine its exposure to the weather. 3. Review the cladding type and its ability to be removed or modified. 4. Identify any pre-existing conditions or underlying problems. Overhang Ratio = Overhang Width Wall Height

15 FL A 15 9 B Window Type A Overhang Ratio = Overhang Ratio = 0.5 Terrain = A Exposure Category = None Window Type B Overhang Ratio = Overhang Ratio = 0.2 Terrain = A Exposure Category = Low 3 of overhang 6 distance of sill to overhang 3 of overhang 15 distance of sill to overhang

16 6 A 24 Window Type A Overhang Ratio = Overhang Ratio = 0.08 Terrain = C Exposure Category = Medium 0.5 of overhang 6 distance of sill to overhang B Window Type B Overhang Ratio = Overhang Ratio = 0.02 Terrain = C Exposure Category = High 0.5 of overhang 24 distance of sill to overhang

17 WINDOW REPLACEMENT ON AN EXISTING BUILDING Determine the type of replacement option 1. Confirm exposure category Done 1. Will there be roofing work in the future which may increase the overhangs? 2. What is the Service Life of interfacing components? 1. Will siding be replace in the near future? 2. What is condition of existing trim and sealants? 3. Will there be Asbestos in the stucco or drywall? 1. Determine the age of the building. Worksafe BC notes that any building older then 1990 can contain asbestos in certain components. 2. Obtain an asbestos review of the building.

30 Where Condensation can form on Vinyl Frame Windows

31 How do you determine if condensation will occur on a window frame or glass? 1. Record the interior temperature. 2. Record the interior humidity 3. Determine the average monthly low exterior temperature. 4. Measure the interior temperature of the window frame or perform a thermal analysis.

33 Features and Options 1. What are Low E Coatings and why do we need them? 2. Dual Sealed glazing units and Argon Gas. 3. Lower maintenance glass coatings. 4. Frame Colour options and how to match aluminum windows. 5. Swing doors and multi point hardware.

34 Triple Versus Double Glazing: A poor triple glazed window is similar to a good double glazed window Casement sash sizes are limited due to added weight Overall added weight of the windows and the willingness for installers Product Cost Sliding 2 pane, 1 LoE to a Sliding 2 pane, 2 LoE 30% increase Sliding 2 pane, 1 LoE to a Casement 3 Pane, 3 LoE 110% increase Casement 2 pane, 1 LoE to a Casement 3 Pane, 3 LoE 60% increase Cost increase significantly when you have to change a double pane configuration to a triple pane configuration.

37 How LoE Works - Simplified Clear Glass LoE 1 Glass (180) LoE 2 Glass (270) LoE 3 Glass (366)

38 Through good design, windows can be used to add comfort in the home LoE is designed to reflect energy back to its source allowing for greater temperature control and increased comfort level. Keeps heat in Reduces heat gain Must be used in conjunction with orientation and shading. Condensation reduction allows for greater mechanical control. Glass surface temperate closer to room temperature will reduce convection currents reducing the feeling of drafts.

39 How to gain winter warmth through windows while avoiding high summer heat gain In certain situations LoE may be eliminated or a single coat system (Cardinal 180) can be applied to gain winter heat while using shading to reduce summer heat

44 Lower Maintenance Glass Cleaner Longer

45 Acoustical Glazing Upgrades Alternating glass thickness causes the sound waves to osculate at different frequencies reducing the transmittance of noise. This is referred to as STC or OITC. Most common glass used in Residential construction is 4 mm thick with 6 mm thick laminated glass.

46 AquaSurTech D200 Background AquaSurTech has been providing paint for the vinyl window market for over 20 years in Europe. Original paint was solvent based. Now all paint is waterborne and low VOC Over 12 million window frames in the market with D200 coating. Paint Bonding The polymer is physically interlocked to the PVC. Reactor in the UK creates short chained polymers that crosslink to the substrate after application.

47 Tested at 70 o F o F Vent holes to reduce heat gain Heat Gain testing has been completed in accordance with ASTM D4803 on approximately 125 different colour options.
