Typically, fiber cement boards are made up of cement and cellulose fibres (plant extracts). While the former is extremely hardy and can be used for high load-bearing applications, the latter is best used for decorative purposes, such as sidings, soffit, and trims, or as a tile backing board.
Fiber cement boards are available in sheets of varying sizes (such as 2,400 × 1,200 mm and 1,500 × 900 mm equivalents) and also vary in thickness, ranging from 3 mm to 20 mm. They have an advantage over gypsum boards (plasterboards) in that they are more resistant to impact. These boards are either water-resistant or waterproof, making them a great addition to bathroom and kitchen projects.
Here are three ways fiber cement board can be useful in your home:
1. Exterior Cladding and Siding
Fiber cement boards have gained considerable popularity as an exterior cladding and siding material. This is because they are far more durable than alternatives such as uPVC or timber cladding, and generally more economical than traditional render, stone, and brick (considering the cost of installation as well).
Apart from the fact that fiber cement boards are extremely resistant to external influences such as ultraviolet rays, salt spray, driving rain, and heat, they are also impenetrable by birds or insects. Further, they are immune to temperature fluctuations and physical impact, requiring minimal maintenance.
In addition, fiber cement boards are available in many different styles with varying textures and colours, allowing homeowners to choose a design that best suits their property. They can also be used for soffits and fascia trim applications. Ultimately, they have gained widespread popularity as cladding mostly because they replicate the appearance of timber while offering a cheaper and more durable alternative.
2. Tiled Wall Substitute and Backing
Fiber cement boards are equally useful inside the house. They are ideal as tile backing boards, particularly in bathrooms, wet rooms, and kitchens. Because these boards are usually water-resistant or waterproof, they make for an ideal substrate in wet areas of the property. They offer greater resistance to mould and mildew and do not degrade as a result of constant exposure to moisture.
Moreover, they help tiles adhere to walls more effectively, increasing the longevity of your tiled walls. They also provide a smooth, stable finish, which is essential for professional tile installation. Owing to their water-resistant and durable nature, fiber cement boards are also frequently used for kitchen worktop substrates and bathroom shelving slabs.
Tip: Different cement board brands offer varying degrees of water resistance, ranging from water-resistant to fully waterproof. Be sure to check manufacturer specifications first to find the right product for wet areas.
3. Flooring Underlayment
Fiber cement boards provide an exceptional substrate for tile flooring. While they can be used anywhere in the house, they are most commonly laid as an underlayment for bathroom and kitchen floors.
Because these boards bond effectively with both timber subfloors and tile adhesives while providing a smooth and rigid surface, they make an excellent choice of underlayment. When using fiber cement boards for flooring, it is important to use boards of an appropriate thickness—typically around 12 mm (equivalent to 1/2-inch)—to prevent tile and grout from cracking under weight while establishing a rigid working platform. Thinner boards (around 6 mm or 1/4-inch) are more commonly reserved for wall tile backing.
