SoliBoard™ HT-Grade

SoliBoard HT-Grade is developed by our team of engineers to offer you a 1400°C rated refractory ceramic fiber (RCF) board, but using standard Alumina-Silica fibers. SoliBoard HT-grade is based on our SoliBulk HA-grade and used in a unique composition which is boosting the classification temperture of our SoliBoard HT-grade to 1400°C without the use of zirconia. SoliBoard HT-grade is manufactured with selected inorganic and organic fillers to deliver high strength and performance in refractory linings and secures minimum shrinkage to temperatures close to classification temperature.


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 HT-grade is an engineering miracle whilst using our unique spun High Alumina Refractory Ceramic Fiber  to provide a board which can perform in a wide range of applications up till 1260°C continuously. SoliBoard HT-grade 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 heaters.

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.

The SoliBoard HT-grade is rated at 1400°C and engineered to perform in a wide range of applications up till 1260°C continuously. The SoliBoard standard product range consists of 3 types of standard refractory ceramic fiber (RCF) boards, an extensive range of low bio persistence (LBP) boards. We also deliver a Special Grade Boards range for High Strength or, when based on PCW fiber, boards for the most demanding applications.
