Colours and Glazing

All Idealcombi product ranges come with low-energy panes, argon gas and “warm edge” spacer technology as standard, which minimise the loss of cold in window perimeter areas. This leads to greater indoor comfort and reduces the heating bill considerably. Our glass is custom made for each window, this gives us a flexibility to add various functions such as noise reduction, solar protection, opaqueness, and security.

There are many solutions available. Consult your sales representative directly so that you are guaranteed a solution that meets your needs.

The total solar energy transmittance, or solar heat gain coefficient (SHGC) value, indicates how effectively solar energy passes through the glass and transmits heat into a building.

• The G-value is calculated based on direct solar radiation passing through the pane (1) and secondary radiation absorbed by the material, which is then radiated internally into an enclosed space (2).
• The lower the g-value, the less energy reaches the building’s interior
• Benefit of a low g-value in summer: building interiors heat up less
• Benefit of a high g-value in winter: lower heating costs
• The optimal g-value is determined in each case by the architect’s calculations for each window that will specify if it will be used to create heat gain or prevent overheating

The thermal transmittance coefficient value describes the amount of energy a building loses through a window.

• U-value determines how much thermal energy is escaping through material
• A lower U-value indicates better insulation, resulting in reduced heating requirements
• While lower U-values are better, it’s important to ensure they are appropriately matched with the rest of the house structure. Getting lower U-values compared to the rest of the house structures (walls, roof) will not return additional benefit.

The light transmittance level indicates the percentage of visible light that passes through the glass.

• The higher the LT-value, the more visible light passes through to the building’s interior
• Factors including the glass thickness, reflectivity and coatings affect the LT-value
• Benefit of a low LT-value: Prevents overheating by limiting the amount of heat that radiates into the room
• Drawback of a low LT-value: The glass is tinted, reducing the amount of light entering the room and affecting the external view
