Float Glass


SGG PLANICLEAR is available in an extensive range of thickness suitable for a wide variety of applications. It can be toughened or laminated for safety benefits or silvered to produce mirrors. It is also suitable for screen printing, acid etching, decoration, sand blasting, lacquering or edgeworking etc.



Whether we're at home, at work, at school, in hospital or in any other kind of building, there are many factors that enhance or detract from our overall sense of comfort and wellbeing – including things like aesthetics, interior design, convenience and ease of maintenance.

It's the balance of the key factors below that provides overall comfort – and helps us to feel good.

SGG PLANICLEAR can be laminated, coated or heat-treated to provide numerous comfort benefits, such as noise reduction, solar control and safe breakage.



Over the past few years the glass and glazing industry has witnessed a growing trend towards clearer float glass substrates. This demand is being driven by the need for a more neutral appearance in both the Architectural (project) market and the Interior glass sector as well as the need for improved passive energy gain in the Residential window market.

For years, Saint-Gobain Glass manufactured SGG PLANILUX®, a high-quality clear glass. Now, Saint-Gobain Glass UK has improved its float glass offer by launching SGG PLANICLEAR®, a new standard float glass specification with lower iron content.

SGG PLANICLEAR contributes to a higher level of Light transmission. This helps to increase the level of natural daylight and reduces the need for artificial lighting – creating a more comfortable environment.

The lower iron content of SGG PLANICLEAR reduces the level of green colouring so that the appearance is clearer and more neutral. This difference is particularly noticeable when viewing the edge of the glass.

Safety glass, which will be either toughened or laminated, depending on where and how it is being used, protects from the risk of serious injury caused by accidental breakage or impact. When it breaks, it breaks safely thus protecting against the risk of serious injury.

The types of safety glass have different benefits:

  • Toughened glass fractures into small relatively blunt fragments upon failure, preventing cutting and piercing injuries associated with large shards of annealed glass.
  • Laminated glass contains a polymeric interlayer, designed to retain sections of glass in the event of fracture, and so prevent shards separating from the main body of the glass. Laminated glass also provides an enhanced level of protection where there is a change in level, and so a risk of falling, or where there is a potential for objects to fall from height onto occupied areas below.

The type and level of safety can vary from one project to the next. Saint-Gobain Building Glass always recommend seeking advice from one our Specification Managers before you proceed with a particular glass type.

SGG PLANICLEAR can be thermally toughened and/or laminated. When laminated by Saint-Gobain, the product becomes part of the SGG STADIP range.



Security rated glass can help protect against break-in attempts or vandalism by delaying, or even preventing, penetration through the glass in the event of forced break in or damage.

To offer security performance, SGG PLANICLEAR must be laminated, and so the SGG STADIP range should be considered where these requirements exist.
