In the realm of high-performance Insulating Glass Units (IGUs), the longevity, energy efficiency, and overall integrity of the system are paramount.
A critical component in achieving these goals is the sealant, which plays a vital role in maintaining the internal environment of the IGU and protecting it from external factors. With decades of dedicated expertise, the Fenzi Group stands as a leading innovator in this field, offering a comprehensive suite of certified, sustainable sealant solutions specifically formulated for the demanding requirements of the insulating glass industry.
Fenzi Group‘s commitment to excellence is reflected in our range of high-performance sealants, each meticulously developed to address specific needs and exceed expectations. These advanced formulations are designed to ensure maximum durability, optimise energy efficiency, and deliver unparalleled long-term reliability for your IGUs.
At the core of our offering are solutions like Thiover, a polysulfide-based secondary sealant renowned for its perfect adhesion to glass and spacers, superior mechanical resistance, and very low permeability, effectively protecting against water vapor and gas leaks. Its solvent-free and sustainable composition, coupled with certifications to key standards (EN 1279-2/3/4, ASTM E2189-10, ASTM E2190-10), underscores its quality and environmental responsibility. 
For primary sealing applications, Butylver offers maximum efficiency. This exceptional primary sealant provides robust resistance against water vapor, gases, and UV rays. Its strong adhesion ensures tight seals, and its zero shrinkage characteristic maintains structural integrity over time. With low thermal conductivity, Butylver further contributes to optimizing overall IGU performance, holding approvals from respected bodies such as Applus+, UNI, CEKAL, RAL 520, and IGCC-IGMA.
Our Poliver AC, a polyurethane-based secondary sealant, is specifically engineered for superior moisture protection and gas retention. Its high mechanical strength makes it ideal for both double and triple-glazed units, and its excellent UV and moisture stability ensures resilience against environmental stressors. Poliver AC is also certified to critical industry standards (EN 1279-2/3/4, ASTM E2189-10, ASTM E2190-10).
Completing our range is Hotver, a fast-setting thermoplastic sealant that revolutionises IGU production cycles. Its rapid setting time optimises manufacturing efficiency without compromising quality. Hotver is not only recyclable, thanks to its reusable thermoplastic formula, but also boasts high mechanical resistance, making it perfect for dual and triple-glazed applications. Its contribution to top-tier energy ratings further highlights its value. Hotver is also certified to the stringent standards of EN 1279-2/3/4, ASTM E2189-10, and ASTM E2190-10.
Choosing the right sealant solution is crucial for the long-term performance of your IG units. Fenzi Group offers a full spectrum of cutting-edge products, each designed to meet your specific requirements and elevate the performance of your insulating glass units. We invite you to discover the difference our products can make.
