faceboo Types of Glass and Windows | Saint-Gobain Glass

Windows are to the house; what fresh air is to us. Just like us, our house too needs to breathe; to inhale freshness and exhale staleness. Windows bring in the much-needed light and air, besides allowing the outdoors in. They showcase the outside world and break the monotony of everyday life.


Windows have a three-pronged or what we call The 3-O Approach - Objective, Orientation and Overall Look.


Windows are beyond mere aesthetics.They

  • Enhance the visual appeal of the house

  • Let in daylight

  • Offer convenience like letting out hot air and enable cross-ventilation

  • Provide energy efficiency, thus reducing power costs.

  • Provide sound insulation from external noise

  • Ensure Safety from both man-made and natural hazards

  • Connect us to the outside world


Not for nothing, are windows designed with a sense of direction.

  • South facing windows will have more sunlight through the day

  • East & West facing windows will get morning and evening sunlight

  • Factor in the direction of the breeze

  • Xtreme

  • Check surrounding buildings and outdoor views to identify the right orientation of the windows

Overall Look:

Base the overall look on the architectural design. For example:

Traditional Kerala Home

Comprises a long, sloping roof to safeguard the home’s walls and cope with the heavy monsoon rains

Displays pillars on walls erected on an elevated plinth, to protect against dampness

Windows: Casement windows on all floors provide both ventilation and views

Modern Kerala Home

Showcases a sturdy horizontal design with spacious open floor plans, deliberate asymmetry, and large glass windows or glass walls

Once the type of window is selected, selecting the frame is the next step to provide durability to the window and ensure its longevity.

Over 90% area of the window is its glass. The type of glass used has an impact on:

The amount of light coming through the window

The flow of heat in and out of the home

The amount of external noise

The energy-efficiency

A. Types of Glass:

Clear Glass - Simple glass that keeps the world outside from the inside Tinted Glass - Enhances the aesthetics of the home Sunban-Ideal for windows in Indian climatic conditions, specially engineered to maximize light and minimize heat; optimises daylighting, cuts UV radiation and up to 70% solar heat and offers superior insulation.

B. Glass Fitment:

Every glass comes with a specific fitment into the window, as a Single Glazed Unit (SGU), Double Glazed Unit (DGU), or Laminated.

Components of Laminated Glass
Single Glazed
Double Glazed
A single layer of glass that provides medium to low energy-efficiency, depending on the glass chosen.
Providing higher energy efficiency, a Double Glazed Unit comprises two panes of glass (an interior glass pane and an exterior one) and an embedded layer of inert gas which creates an insulated environment between the interior and exterior of a window.
Comprising two or more layers of glass sandwiched with a polymeric interlayer like Polyvinyl butyral (PVB), Laminated Glass provides safety and acoustic comfort.
