Use of Laminated Glass

Laminated glass is used in office buildings, hotels, restaurants, shopping malls, public walkways, hospitals, libraries, museums, churches, airport terminals, residences & apartment buildings, noise control applications, embassies, computer centers. High security places, for example, banks, teller, and drive-through windows, ticket windows, gas stations, currency exchanges, armoured vehicles, jewellery shops and burglar resistant showcases. Other areas where laminated glass is used are...

Class of Structure

The buildings structures are classified into the following three different classes depending upon their size Class A - Structures and or their components such as cladding, glazing, roofing etc., having maximum dimension (greatest horizontal or vertical dimension) less than 20m. Table 4.6 Design Wind Pressure 'PZ' for Wind Zone-1 (Basic wind speed 33 m sec) Table 4.6 Design Wind Pressure 'PZ' for Wind Zone-1 (Basic wind speed 33 m sec) Table 4.7 Design Wind Pressure 'PZ' for Wind Zone- II (Basic...

Factors Determining the Performance of Glass

Factors, which determine the performance of glass are defined as follows 1. Visible light transmittance ( ) The percentage of light transmitted in the visible spectrum, from 380 to 780 nanometers. 2. Visible light reflection ( ) The percentage of visible light reflected 3. Ultra Violet Rays ( ) Percentage of amount of ultra violet rays transmitted. 4. Solar Energy Transmission ( ) Percentage of incident solar energy transmitted by glass. 5. Solar Energy Reflection ( ) Percentage of incident...

Laminated Annealed Glass

Light Transmission needs to be optimized so as to avoid glare and minimize artificial illumination. It mainly depends on use of buildings. Retail shopping areas may require maximizing light transmission due to higher visibility whereas software parks may require minimizing light transmission to reduce glare. Glass needs to transmit true colour, which means the colour of light transmitted through the glass should be close to that of light through the clear glass. This is essential to avoid false...

Net Design Wind Pressure PntT

Net design wind pressure (P ) is an important parameter governing the thickness of glass to be used in the window panels. It depends on several factors i.e. location of building (wind zone), construction patterns around buildings (terrain category), topography of site, building plan and height etc. Net design wind pressure (Pnet), may be defined using the following equation where, Cp Net pressure coefficient Pz Design wind pressure at height 'z' (N m2) Important terms related to the equation...

Types of Normal Annealed Glass

It is normal annealed glass, though clear amp transparent, It does posses some colour tint usually greenish. It is due to presence of some impurities such as iron. Clear glass has very high energy transmission when exposed to sun light. It provides a clear view of the objects across it. Applications Used in doors, windows, solar applications, shelves etc. It is also used for further processing to other glass types. 2.1.3.2 Tinted glass It is normal glass that is coloured by...
