SoliBoard HT-Grade

SoliBoard HT-Grade has been developed by our team of engineers to offer you a 1400°C rated refractory ceramic fiber (RCF) board, using our standard 1260°C fibers. SoliBoard HT-grade is based on our SoliBulk HP-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.

The SoliBoard product range is manufactured using the same Ultra Low Shot technology utilized throughout our fiber product range. SoliBoard can be used for a wide range of application in refractory linings or in domestic appliances.

We manufacture the SoliBoard product range on our continuous board line, with state of the art drying techniques. This drying process is much more sustainable, leading to 50 % energy saving compared to conventional drying techniques and allows us to dry the product to the core to a thickness of 100 mm. As it is manufactured on our continuous board line, which spans over 200 m (600 ft), our product are much more controlled and consistent compared to batch manufactured vacuum forming process boards. As a result we can offer you a uniform, lightweight, low shot and stable board at high consistency, quality and performance.

The SoliBoard HT-grade is rated at 1400°C and engineered to perform in a wide range of applications up till 1250°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.

Boards from high temperature Refractory Ceramic Fiber (RCF) insulation wool and selected fillers.

Temperature range

SoliBoard HT-grade has a classification temperature of 1400°C.

The maximum continuous use temperature provided on the website is a guideline and only applicable in a clean oxidizing atmosphere.

First firing

All Board formulations contain a small amount of organic binder to improve the cold handling strength which burns out on first firing at approximately 200-300°C.


SoliBoard is available in the standard dimensions 1200×1000 mm or 1000×600 mm which are supplied on carton boxes of 120-150 mm high (based on the thickness of the board) and Please refer to the list below for packaging details of the SoliBoard product range other sizes are available on request.
