Choosing the right type of glass for windows is a crucial factor that affects the comfort, safety, and energy efficiency of a building. Additionally, the proper selection of glass can significantly impact energy cost reduction, increase acoustic insulation, and provide protection against break-ins and other threats. There are several reasons to explore this topic, and here we present our comprehensive guide to types of glass. We warmly invite you to read on!


First and foremost, it is essential to start by understanding that different types of glass meet specific requirements. Therefore, it is important to understand the benefits that each solution offers. Below, we provide a detailed overview of the various types of glass available on the market.



1. Insulated Glass Units (IGUs)


Let’s start with what exactly these are. Insulated glass units consist of two or more panes of glass joined together with a space between them filled with air or gas, such as argon. This construction improves the thermal and acoustic insulation of windows.


  • Low-E Glass: Specifically designed to minimize heat loss, leading to significant heating savings and improved energy efficiency. These panes are coated with a low-emissivity layer that reflects heat back into the room.


  • Warm Edge Spacer Bars: Equipped with spacers with low thermal conductivity, reducing thermal bridges and increasing the insulation of the entire window structure. This reduces heat loss and improves thermal comfort indoors.


  • Solar Control Glass: Effectively regulates the amount of sunlight entering the interior, preventing overheating and reducing air conditioning costs. Additionally, it protects against harmful UV radiation.


  • Safety and Security Glass: Provides a high level of security through reinforced construction that makes break-ins more difficult and minimizes injury risk in case of glass breakage. Ideal for public and residential buildings.


  • Bullet-Resistant Glass: Specialized glass with enhanced resistance that withstands extreme impacts, providing additional protection in high-risk areas.


  • Acoustic Insulation Glass: Reduces external noise, which is particularly important in buildings located in busy urban areas. This glass significantly improves acoustic comfort indoors.


  • Fire-Resistant Glass: Enhances the fire safety of a building, as it is designed to withstand high temperatures and delay the spread of fire. Used in industrial and public utility buildings.


  • Ornamental Glass: Decorative glass that combines aesthetics with functionality. Ideal for applications where privacy is needed while still allowing light to pass through.


  • Internal Grilles: Offer additional decorative elements that divide the glass into smaller sections, adding a classic look and style to the windows.



2. Special Glass


Special glass is also made from insulated glass units.


  • Tempered Glass (SG): Increased impact and temperature resistance, making it ideal for exterior applications and areas with a high risk of mechanical damage.


  • Curved Tempered Glass: Unique glass with a curved form that retains the strength properties of tempered glass. Used in architecture where unusual shapes are required.


  • Heat-Soak Test (HST): A process for testing tempered glass to eliminate the risk of spontaneous breakage, ensuring additional reliability and safety.


  • Mechanical Edge Processing: Precise edge processing of glass, increasing user safety and aesthetics.


  • Glass with Holes: Glass with drilled holes, allowing for the installation of additional structural elements.


  • Glass with Cut-Outs: Precise cut-outs in glass, tailored to specific architectural and installation needs.


  • Printed Glass: Technology that allows aesthetic patterns to be applied to the glass surface, enhancing its decorative value.


  • Silk-Screen Printed Glass: Glass with patterns obtained through silk-screen printing, ideal for decorative and functional applications.


  • Spandrels – Opaque Glass: Used in building facades, opaque glass, often with a metallic coating, that hides structural elements.


  • Laminated Glass: Composed of multiple layers of glass bonded with PVB film, providing a high level of safety in case of breakage.


3. Single Panes


The basic type of glass used in windows, which does not offer the properties of insulated glass units but can be used in less demanding applications.


Choosing the right glass largely depends on the specific needs of the building and personal expectations. The variety of glass types available on the market allows for product customization to individual requirements, ensuring comfort, safety, and aesthetics.
