4SG Insulated Glass, powered by Ködispace 4SG spacers from Germany's Kommerling, represents a breakthrough in insulating glass technology. The core 4SG spacer is a flexible, thermoplastic system with integrated desiccant, completely replacing traditional edge systems that combine spacers, desiccants, and primary seals. Its ability to form strong chemical bonds with glass and silicone makes it uniquely suited for structural glazing, delivering unmatched performance in durability, design, and energy efficiency.

Core Advantages:

1.QUALITY & LONGEVITY：RESILIENT SYSTEM

The main stress in the sealing of box spacer profiles is on the butyl applied to both sides. Expansion and contraction of the insulating glass caused by climatic stress leads to enormous strain in the butyl. This permanent stress caused by compression and elongation of the primary seal, can cause seal failure over time. However the edge bond with KÖDISPACE 4SG remains elastic which results in considerably less stress on the bond and hence greater longevity.

• Excellent compensation of climatic stress

• Optimal sealing barrier against gas loss and penetrating moisture

• Absolutely tight joint due to CNC application

• No extra butyling of joints and corners required

2.CREATIVE FREEDOM & LIMITLESS DESIGN POSSIBILITIES：

THE INVISIBLE SYSTEM

conventional metal spacers can affect the visual appearance with their shiny and perforated surfaces. Matt black 4SG reflects the color of the window frame and therefore renders the space between the panes virtually invisible, resulting in a visually larger glass surface.

THE PRECISE SYSTEM

Exact spacer positioning is impossible by hand with triple glazing and conventional profile systems. Misalignment will detract from the visual appearance of the insulating glass. The fully automatic application of 4SG helps triple glazing achieve the greatest precision, leading to visually flawless results.

THE VARIED SYSTEM

4SG offers flexible creative options with consistently high quality including large and curved insulating glass. The reflection of the frame color negates the need for various spacer colors.

3.THE LONG TERM ENERGY EFFICIENT SYSTEM WITH ADDED VALUE：

4SG offers top-class Psi values. This means minimal heat loss along the linear thermal bridge at the glass edge and thus maximum improvement of the Uw values for windows and Ucw values for facades.The outstanding performance of 4SG has been tested and awarded as a Certified Passive House Component.

• Metal-free material with very low thermal conductivity

• Lower heat loss

• Saves heating costs

• Minimization of condensation

• Lowering the health risks caused by mould spores

• Higher living comfort and cosiness

• Contributes to CO2-reduction

Main Characteristics:

Gas-tight

• Minimal Argon gas leak

• Lowe doesn't oxidize

• Lifespan 3 times longer than aluminum spacers

• Long-term Energy-saving

When 90% argon gas-fill is used in a low-e IGU,instead of air, the window's insulating value can improve by up to 16%.

Flexible spacer

• Flexible spacer effectively eliminates glass,deformation caused by pressure difference.

• Reduces overflow and tearing of butyl glue, and avoids argon gas leakage,desiccant leakage.

Completely metral-free

• Reduce convection in the room.

• Minimize condensation on window edges

• The dew point is below -51°C

• 10-15%,improvement of the windowU-value

4SG Insulated Glass isn't just a product-it's a fusion of German engineering, durability, and design freedom. Ideal for structural glazing, passive houses, and high-end architectural projects, it delivers long-term value through energy savings, aesthetic appeal, and unmatched reliability.
