Standard double glass: tempered with insulation comparable to HR++

Our standard double glass offers robust insulation properties comparable to HR++. Its unique glass specifications include:

• HST tempered glass for safety
  The glass undergoes Heat Strength Toughening (HST), a thermal treatment that makes it extra strong and resistant to large temperature variations. This safety feature ensures that, like glass used in car windows, it shatters into small, less harmful pieces if broken.
• Argon-filled cavity
  The space between the glass layers is filled with argon gas, enhancing insulation beyond what dry air offers and contributing to better overall energy efficiency.
• Low E Coating for thermal efficiency
  A special low-E coating on the inner layer reduces heat loss, keeping warmth outside in the summer and inside in the winter, all without compromising light transmission.

Triple glass: Elevating insulation to HR+++

For even better insulation, opt for triple glass, which has three glass layers and two argon-filled cavities. This setup provides an impressive HR+++ insulation level, meeting stringent standards, including those for passive homes. To achieve this, glass specifications such as a U-value below 0.8 W/m²K are necessary. Note that U-values can vary based on glass size; narrower sheets tend to have higher U-values.

Laminated glass: Multi-layered safety glass

Laminated glass, also known as safety glass, is made up of multiple glass layers with transparent PVB foil between them. If broken, the foil holds the glass together, preventing large gaps. The glass specification here depends on the thickness of the glass and the number of foil layers, which can be adjusted as needed. However, note that the maximum length for laminated glass is typically smaller than for double or triple glass, with a standard maximum of 3,100 mm compared to 4,150 mm.

Opal glass: Privacy and light transmission

For bathrooms or spaces where daylight is needed without transparency, we offer opal glass with a white inner layer. This layer provides privacy without sacrificing light transmission, making it ideal for areas where visibility needs to be controlled.
