Insulating glazing

  • Insulating glazing is made up as follows: thickness of the 1st piece of glass (in mm), air space dimensions (in mm), thickness of the second piece of glass (for example: 4-16-4). For triple glazing, the composition also includes the dimensions of the second air space, and the thickness of the third piece of glass (for example: 4-12-4-12-4).
  • Various types of glass can be used:
    • low-emissivity coated glass,
    • solar control glass,
    • laminated glass,
    • tempered glass, ...
  • The choice of composition depends on the desired performance and the space available in the glazing channel in the frame.
  • Insulating glazing must be assembled in such a way that the glass is both watertight and break-resistant. CEKAL certification focuses in particular on :
    • resistance to damp penetrating into the insulating glazing assembly gasket,
    • performances ratings.
