When you contact Square 1 with your glass enquiry, our experienced and helpful team will determine the right glass for you. We will ask some key questions about your requirement which will enable us to discuss the various options with you:

Choosing the right glass for you

  • The height of the glass you require
  • Placement of the glass balustrade (internal or external)
  • Is a stainless steel handrail required
  • The loading the glass balustrade needs to achieve – this can be provided by a structural engineer or your local building control officer
Once we have established this information, we can discuss what thickness of glass will be required and whether this will be provided as toughened, heat soaked glass or toughened and laminated glass. Toughened glass is ideally suited to most applications where safety is critical, but consideration should be taken if the glass balustrade is at a high level. Toughened & laminated glass is constructed of two pieces of toughened glass either side of a laminate interlayer and offers the same strength under impact as toughened glass with a crucial safety difference – If the pane is damaged resulting in the glass breaking, the fragments will be retained by the laminate interlayer, enabling the system to still act as a barrier until a replacement can be installed. As your glass balustrade will not only need to look great it is also designed to be a key safety feature in your environment. As safety is paramount to Square 1, we can call upon the services of an industry recognised Structural Glass Consultancy who, from the information provided to them, can determine precisely what type of glass is required to achieve the strength it is intended for. For your peace of mind, they can provide a written report detailing the calculations used to determine this. The glass delivered to you will have polished edges and radius corners as standard unless otherwise asked for. We can also supply frosted/sandblasted glass, silkscreen printed glass as well as etched glass and drill holes up to 30mm diameter – contact our friendly team for more information.
