Hotver A+

One-Component hot-melt sealant with high gas retention

Hotver A+ is the newest and most advanced One-Component hot-melt sealant in the Fenzi range. It retains the same ease of use as Hotver 2000 while offering superior performance and significantly improving the gas leakage rate of IG units. it is renowned as one of the best-selling products in the UK, highly favoured by customers seeking to achieve an A+ rating, thanks to its exceptional gas retention in IGUs.

Hotver A+ is a specialized thermoplastic hot applied sealant designed specifically for sealing insulating glass units. Its rapid setting properties facilitate swift production of double glazed units, ensuring efficient delivery. Any excess product can be recycled, as it is capable of being reheated at the conclusion of processing operations. These caractristics make Hotver A+ an ideal sealant for producing high-energy efficiency windows that meet the strictest national and European ratings.

Hotver A+ sealant is free from solvents. It is versatile and can be utilized for both dual and triple seal panel productions. It is compatible with various application methods, including manual and robotic technologies.
