Insulating Glass
H.B. Fuller | KÖMMERLING offers the worlds most comprehensive product range for the glass industry and all from a single source.
Our primary sealants, reactive and non-reactive secondary sealants fulfill the highest requirements of international certification standards. They are laboratory and field-tested in a variety of extreme and accelerated aging conditions, ensuring reliability and application flexibility. We offer a solution for nearly every Insulating Glass (IG) configuration. -
Primary Seal
Polyisobutylenes
The primary sealant is the key to maintaining a moisture vapor and gas tight seal for long term unit performance. The polyisobutylene seals the spacer width to the glass and prevents moisture from entering the insulating glass unit and keeps the gas sealed inside and unable to escape.
Our polyisobutylene sealants are characterized by an extremely low moisture vapor transmission rate and excellent gas retention while providing superior adhesive properties on glass and spacer bars.
All of our PIBs fulfill the requirements of EN 1279 and ASTM E2190.Specific Properties
- Extremely low moisture vapor transmission rate
- Very good gas retention
-
Secondary Seal
The secondary seal acts as a second layer of sealing but is more importantly, the structural component of the insulating glass edge. It is responsible for maintaining the structural integrity of the unit during expansion and contraction caused by environmental forces such as fluctuations in temperature, barometric pressure and wind speed. All of our standard secondary sealants are fully compliant with EN 1279 and ASTM E2190 and are approved for use with our Direct Glazing Systems.
Polysulfides
Our 2-component polysulfide sealants are characterized by a low moisture vapor transmission rate, excellent gas retention and a wide range of adhesion properties. Tolerant of mix ratio deviations of up to ± 20 %.
Specific Properties
- Approved by CEKAL
- Certified according to GMI
Polyurethanes
In addition to a low moisture vapor transmission rate and good gas retention, our 2-component polyurethane sealants are characterized by fast adhesion build-up as well as very good adhesive properties to the surfaces of many frame materials.
Specific Properties
- For use in serial production
- Approved by CEKAL
- Certified according to GMI
Silicones
If high UV stability of the edge sealant is needed, silicones are preferred as secondary sealants. Our silicone sealants not only have excellent UV resistance, but also particularly good weathering and temperature resistance.
Specific Properties
- Approved by CEKAL
- Certified according to GMI
Hot Melts And Reactive Hot Melts
Our hot melt sealants are characterized by an extremely low moisture vapor transmission rate and superior gas retention. As they easily melt in tank and drum melting equipment and are easy to process, they are perfectly suited for both automated production and manual equipment.
Specific Properties
- Processing temperature +170 °F to +350 °F
- No loss of material, no waste disposal issues
- No purging or flushing necessary
- No mixing issues

Glazing
For More Reliable Windows And Higher Safety Levels
The demands placed on modern windows are high! They need to be energy-efficient, visually appealing, flexible in shape and size, as well as burglar resistant. Direct Glazing is the key to a new world of window bonding: insulating glass is bonded into the window sash, which leads to significant improvements in the window‘s static properties. Load transfer no longer occurs selectively over setting blocks, but rather over the entire bonding area. This allows for thinner frames, lower weight, larger pane sizes, unusual window shapes and a higher safety level.
Direct Glazing can be realized with all types of window frame material, from wood via plastic to aluminum. Depending on the profile system, different bonding positions are possible: overlap, rebate and glass edge.
With Ködiglaze, H.B. Fuller | KÖMMERLING has developed a special product range for this innovative technology. Our Ködiglaze adhesives are polyurethane or silicone based and characterized by very good weathering performance, temperature resistance and an optimal relationship between stability and flow behavior. They also offer excellent creep resistance and are, of course, compatible with our insulating glass sealants.
Specific Properties
- Formulation and properties adapted to insulating glass secondary sealants
- Can be processed either as 1- or 2-component system

Facade Technology
System Solutions For Structural Glazing
Glass is a material that provides high quality natural daylight, timeless elegance and transparency. This is why glass façades have had a significant impact on modern architecture and will define our cityscapes for decades. Façades must satisfy the most demanding aesthetic expectations whilst performing as technically smart systems and fulfilling a multitude of construction compliant functions. These requirements are safely and perfectly reconciled in glass façades built with our structural glazing solutions.
Our high-performance, silicone-based structural glazing products guarantee that façades and their fascinating unique designs will be long-lasting even under the most extreme climate conditions. With Ködispace 4SG, our unique Warm Edge System developed especially for use in structural glazing, extremely tight and durable gas-filled glass façades can be realized.
