3 LEARNING OBJECTIVES How to incorporate privacy and translucency in building designs using glass Understand the types of decorative glass, and design and application possibilities How the different types of decorative glass are made Key considerations of specifying decorative glass 01

4 Course Outline How it is Made What Does the Product do for the User? Specifying Technical Standards Applications Suitable & Not Suitable

5 WHAT DOES THE PRODUCT DO FOR THE USER? Surface diffuses light Reduces Glare Combine or mix privacy and light transmittance in different areas 03

6 WHAT DOES THE PRODUCT DO FOR THE USER? Offers depth or visual effect Personalize by adding color or texture to the glass Exterior applications for birdfriendly buildings 04

7 ACID ETCHED GLASS Acid Etched Glass is often used in the following applications INTERIOR GLAZING EXTERIOR GLAZING SPECIALTY APPLICATIONS 05

8 ACID ETCHED GLASS Definition Glass that has been chemically treated with an acidic material, such as hydrofluoric acid to obtain a translucent appearance. The treatment can be applied to provide different levels of translucency, either uniformly over the entire surface or in selected areas creating decorative patterns. 06

9 ACID ETCHED GLASS Benefits Varying levels of translucency available Privacy without affecting light flow Wear resistant / low maintenance surface 07

10 ACID ETCHED GLASS How It s Made Surface is polished with a chemical solution, which includes hydrofluoric acid Selective areas can be masked to create etched patterns or designs 08

11 ACID ETCHED GLASS Specification Considerations Specify the desired finish [and glossreading tolerance]; varying levels of translucency available Choose glass substrate; thickness and color appropriate to application Full surface etching, single or double sided etching or etched pattern Gradient or fading effects are available, as well as slip resistant surfaces 09

12 SANDBLASTED GLASS APPLICATIONS 10

13 SANDBLASTED GLASS How It s Made Protective masking placed on clear areas Abrasive particles sprayed at high velocity Masking removed and protective coating applied 11

14 SANDBLASTED GLASS Abrasive material sprayed onto the surface Full coverage or decorative pattern Different levels of translucency Gradient fade patterns Applied to one or both surfaces 12

15 SANDBLASTED GLASS Specification Considerations Interior vs. exterior Level of translucency Pattern on one or two sides Maintenance Coating warranty 13

16 CARVED GLASS APPLICATIONS GLASS APPLICATIONS GLASS APPLICATIONS 14

17 CARVED GLASS 3 dimensional look Carved into the surface with differing depths Creative, sculpted image 15

18 CARVED GLASS How It s Made Apply protective masking Carve each piece of the pattern in order of depth Specification Considerations Follow fabricator s maintenance guidelines Glass strength (heat treating) 16

19 TRANSLUCENT & OPAQUE COATINGS Translucent coatings are often used in the following applications TRANSIT SHELTERS SPANDREL GLASS SIGNAGE 17

20 TRANSLUCENT & OPAQUE COATINGS Translucent coatings are often used in the following applications INTERIOR GLAZING SHOWERS 18

21 TRANSLUCENT & OPAQUE COATINGS Created by applying inks to glass through screen printing Can be solid coverage or pattern Available in many colors, patterns & translucencies 19

22 TRANSLUCENT & OPAQUE COATINGS How It s Made Silkscreen Pattern created with film and silkscreen Inks pushed through clear areas and applied to glass Ceramic Frit fused to the glass when tempered Organic Coatings chemical bond 20

23 TRANSLUCENT & OPAQUE COATINGS How It s Made Digital Printing Image is printed directly on the glass similar to an ink jet printer on paper Glass can be tempered Organic Coatings chemical bond 21

24 TRANSLUCENT & OPAQUE COATINGS Specification Considerations Application Maximum Size Coating Opacity Pattern and Colors Pattern Resolution Compatibility Long or short run quantities 22

25 SLIP RESISTANT GLASS FLOORING STAIRS BRIDGES 23

26 SLIP RESISTANT GLASS Increases dynamic coefficient of friction Safety for walking surfaces Creative flooring design 24

27 SLIP RESISTANT GLASS How It s Made Self texturized enamels Acid etch glass Particles fused to the surface Sandblasting Cast or Patterned Glass with slip resistant surface 25

28 SLIP RESISTANT GLASS Specification Considerations All glass flooring must be engineered Clarity or diffusion of the glass Type and density of the slip resistant pattern Desired slip coefficient based on recognized test methods *Performance specifications cannot be made without referencing a recognized test method 26

29 DECORATIVE INTERLAYERS CANOPIES INTERIOR GLAZING PUBLIC ART PIECES 27

30 DECORATIVE INTERLAYERS Visual effects Custom graphics Unique colors Privacy 28

31 DECORATIVE INTERLAYERS How It s Made PVB, EVA, Ionomer Layered in a sandwich Cured through heat & pressure Resins Poured or pumped between glass Cured by adding chemicals or UV light 29

32 DECORATIVE INTERLAYERS Specification Considerations Correct type & thickness of interlayer Suitability to conditions and exposures Glazing system compatibility 30
