How to choose a glass specification for a glass roof?

There are multiple design options for a glass roof. As not every structural glass has the same properties, it’s important to opt for the correct glass specifications to make the glazed roof system more practical and efficient.

Here is a breakup of the type of glass according to the height of installation.

HeightType of glass Specifications
Upto 5mToughened/ Laminated/ Wired Glass

Inner pane can either be toughened or laminated. The Upper pane is to be toughened.

5m-13mToughened/ Laminated/ Wired Glass

Toughened glass with maximum 6mm thickness.

Panes less than 3sq/m.

The Inner pane has to be laminated or toughened.

The Upper Pane to be toughened.
Above 13mLaminated or Wired GlassThe Bottom Pane has to be laminated.

Glass roofs can either be constructed with single panels or multiple panels. A single panel roof works well for structures that seek maximum aesthetics whereas multiple panels come in with extra functionality. 

The glass specification can be chosen based on the performance as well, like:

  1. Low-E Coating Glass: The glass with low-E coating serves with extra thermal efficiency to maintain the heat levels within the interiors.
  1. Tinted Anti-sun Glass: Tinted glass can be opted for the outer pane to provide the advantage of lowered solar heat gain.
  1. Large Pane Roof light: It serves as an economic option due to its great thickness and pane size. 
  1. Triple Glazing: Triple glazing offers sound as well as heat insulation.
  1. Solar Control Glass: Solar control glass comes in a slightly grey or green tint which enables 70% of the light to pass through it but only 30% heat makes its way to the interiors. 

Low iron glass can also be opted for a clear glazing and maximum clarity of the views.

How are glass roofs supported structurally?

Structural glass roofs require support to hold the whole system. This can be done with low iron glass beams for clean and transparent aesthetics. This frameless detail is kept at the edges and conceals the brackets and joints used in the glass beam. 

For the joints where the structural glass roof meets vertical sections like walls, glass fins can be placed to support the structure. This transparent detailing offers a clean and neat design with enhanced visual appeal.
