SoliBoard ULS-Grade

SoliBoard™ ULS®-Grade

The low bio persistence grade of the SoliBlanket product range is labelled our ‘ULS’ grade. The SoliBlanket ULS-grade is the first Generation III manufactured, Ultra Low Shot, low bio persistence (LBP) high temperature insulating fiber blanket worldwide. The SoliBlanket ULS-grade has a classification temperature of 1200°C and is engineered to perform continuously in a wide range of applications up till 1050°C continuously. As a result, SoliBoard ULS-grade is a ideal choice for refractory installations, but is particularly  populair for use in domestic boilers.

All products in the SoliWool ULS fibers product range, like the SoliBoard ULS, meet the requirements specified under NOTE Q of European Regulation 1272/2008. All SoliBoard ULS products are therefore exonerated from labelling requirements in Europe.



Vulcor is proud to introduce you our SoliBoard product range, which is manufactured on our state-of-the-art production line, the result of years of combined production knowledge and engineering excellence. It might sound strange to start a product page with an explanation on the manufacturing process, but as this has been a line of break throughs, it also explains why this product is so much different than the competition offering.

SoliBoard is manufactured on our continuous board line which has a total length of approximately 300 meter and a production width of 1200 mm. This line was set up in 2019, and is not only fully PLC controlled, but also equipped with robots to minimize manual labor. Our board line is equipped with the latest drying techniques, and is enabling double side surface treatment. This allows us to not only secure the highest quality, but also allows us to be competitive at high output.

Next to that we utilize a highly efficient drying technique which does not only reduced our energy consumption with 50 % compared to conventional forced air drying, but also allows us to manufacture uniform, lightweight, low shot and stable board up to a thickness of 100 mm at high consistency, quality and performance. In a world where reducing energy consumption and minimizing CO2 emissions is part of sustainable environmental drivers, it is good to realise that we have already taken the first step.

In the SoliBoard product range, SoliBoard ULS-grade is our standard Low Bio Persistence (LBP) fiber based board with a classification temperature of 1200°C. SoliBoard ULS-grade is engineered to perform in a wide range of applications up till 1050°C continuously. SoliBoard ULS-grade is taking great benefit of the Ultra Low Shot spining technology, which is commonly used for the production of our fiber products. SoliBoard is produced with a very tight thickness tolerance and offer unparalleled flatness. As a result the SoliBoard, compared to other types of board, offers better machining characteristics in CNC cutting. With SoliBoard you can easily tailor the board into a precision machined shapes for domestic boilers and heater.

Vulcor is offering one of the most extensive product ranges in high temperature board products. We offer a complete series of standard boards, a high strength series which is both offering higher green strength as better strengh after first firing, and a special series which are manufactured from mixed fiber chemistries (typically using very high temperature resistant PCW fibers) for the most demanding applications.
