Minerit HD (aka Cembrit Construction and Cembrit Raw) is an untreated fiber cement board that allows the authentic appearance of the rough fiber-cement to stand out. In nature, Minerit HD is a building board which can be installed for facade purposes, when a natural and rough expression is desired. Minerit HD is a natural material and variations may occur in the individual boards and from board to board, adding a lively expression to your facade. Minerit HD is a high quality fiber cement building board used as both a building board as well as a part of a ventilated facade solution.

Best in class exterior cladding
A smooth, natural gray fiber cement board with an even-quality surface that allows for effective staining.
Heavy Duty façade boards arcell namextremely well suited to both new buildings and the renovation of old buildings. Heavy Duty is a safe construction material for façades, balconies and footings and for agricultural construction. Heavy Duty’s smooth, natural gray and even-quality surface allows effective staining or painting if desired, but does not require any surface treatment.
Heavy Duty is a Finnish product that is made of clean and non-hazardous raw materials. As a Finnish product, Heavy Duty is designed to withstand wear and extreme weather conditions of the north, such as major temperature and air humidity fluctuations. In addition, Heavy Duty boards are noncombustible.
Heavy Duty is available in 4 by 8 foot and 4 by 10 foot sheets, with a standard thickness ranging from 1/4 to 3/8 of an inch
Specially developed for exterior cladding, Heavy Duty (HD) is strong, durable and able to withstand extreme climatic and working conditions. Its smooth, cement gray surface provides the perfect base for a variety of finishes and composite panels.
Ideal for any application where the strongest cement boards in the Minerit range are required:
- Exterior Cladding
- Sports and Leisure Centers
- Agricultural Buildings
- Balconies
- Production Facilities
- Prefabricated Units
- Stairways
- Laminated Panels
- Squash Courts
- Fume Hood Liners
- Mechanical Screens
