  2. Tinted Anti-sun Glass: Tinted glass can be opted for the outer pane to provide the advantage of lowered solar heat gain.
  3. Large Pane Roof light: It serves as an economic option due to its great thickness and pane size. 
  4. Triple Glazing: Triple glazing offers sound as well as heat insulation.
  5. 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.
