The Bridgewater Glassary: A Glossary of Glass Terms

If you’re looking for glazing services, whether that’s some simple window films or double glazing for your home or entire office, navigating some of the confusing glass terms can be confusing. Want to know the difference between tinted and toughened glass? Don’t worry, just keep reading.


  • Balustrades (glass) – large rectangular panels which are attached either side of staircase. They often support handrails, too.


  • Bevelled glass – often used ornamentally, bevelled glass is created by taking thick panels and creating an angled surface cut. The uneven recesses reflect light in an interesting way.


  • Coated glass – two panels of glass with a space in the middle to insulate the unit. It has excellent insulative properties.


  • Fire rated glass – specially reinforced glass which can resist flames and smoke. It’s often used in office buildings.


  • Float glass – made by floating molten glass on a bed of molten metal, float glass is uniformly thick and very flat.


  • Frosted glass – glass which has been sandblasted, rendering it translucent. Used in many commercial and residential buildings for privacy.


  • Glass cutting – quite simply the process of cutting glass with a glass cutter.


  • Laminated glass – a type of safety glass which holds together when shattered. Often used in commercial buildings to aid the prevention of crime


  • Low-e glass – an abbreviation of low emissivity, low-e glass has an extremely thin, transparent coating which reflects heat, making it great for summer


  • Mirrored glass – a metal coating is applied to one side of the glass and sealed with a protective layer for a mirrored effect. Used for interior design purposes, normally to create the illusion of space


  • Painted glass – available in both float or frosted glass, back painted glass tends to be used simply to inject colour into a room


  • Patterned glass – like painted glass, patterned glass is usually used for decoration. It’s usually created by contrasting frosted and transparent glass


  • Secondary glazing – the adding of another smaller window inside an existing window. It can be an excellent way to insulate and soundproof your windows


  • Tinted glass – by altering the chemical formulation of regular glass, a tinted effect can be created. It’s often used for UV protective purposes and to reduce glare in commercial buildings


  • Toughened glass – also known as tempered glass, toughened glass is created using a thermal tempering process making it the ultimate safety glass


  • Window films – a thin laminate film that can be installed over the interior or exterior of glass surfaces, usually for protection, privacy or thermal benefit


  • Wired glass – wire mesh is added into the structure of the glass, improving its durability and fire resistance greatly
