The following comparison chart is designed to help you choose the perfect combination of SAINT-GOBAIN GLASS products that will enable your new conservatory to exactly match your specific criteria.

Benefits of glass over polycarbonate roof panels:

  • A glass roof dramatically improves the vision area from within, opening up more views, allowing in more natural light and instantly giving any conservatory a wow factor
  • A dramatic reduction in the noise of falling rain with a glass roof
  • Each of the four tint options has a character to suit your own
  • Stays clean and mould free for clearer views
  • Better thermal insulation (when combined with SGG PLANITHERM 4S) compared to 25mm polycarbonate


  • U-value - measures internal heat loss. The lower the number, the greater the insulation
  • W/mK - is the measure in Watts of heat lost per square metre per degree in temperature (Kelvin).
  • Self-cleaning glass - glass with a photocatalytic and hydrophilic coating which harnesses both light and water to break down organic dirt and adherence of mineral material.
  • Solar heat - sun's radiant heat in light which is transmitted through or reflected by glass.
  • Light Transmission - the proportion of the visible light spectrum which is transmitted through the glass.
