Glass Glazing

Solar-control glazing

Selective coatings that balance useful daylight with incoming solar energy.

  • Control of incoming solar energy
  • Daylight and appearance balance
  • Useful for large or sun-exposed glazing

Product details

Daylight, with solar gain considered.

Solar-control glass is useful to discuss for large or sun-exposed openings where incoming heat and glare affect comfort. Selective coatings can retain daylight while reducing the proportion of solar energy entering the space.

Orientation, shade, ventilation and the size of the glazing all influence the room. Light transmission, solar factor and glass appearance should be compared as a whole rather than choosing on one number.

Your choices

Match the coating to the room.

Orientation and room use

Share the direction of the opening, existing shading and any overheating or glare concerns.

Coating selection

Compare available coatings for daylight, solar factor and appearance within the selected frame system. A lower g-value admits a smaller share of solar energy; light transmission describes how much visible light passes through.

Your project

Describe the sun and room use.

Share the direction and size of the glazing, existing shade and the times the room becomes uncomfortable. Tell us whether heat, glare or preserving daylight is the main priority.
