Fiber Cement Siding
Fiber Cement Siding

Fiber cement is a material used in construction that is designed to mimic the appearance of wood without being susceptible to wood’s natural weaknesses: fire, pests and rotting. Fiber cement is made from a mixture of sand, cement and cellulose fibers. Fiber cement siding has advantages that make it an appealing choice for building construction. Thick fiber cement is highly resistant to impact damage, giving it a competitive edge versus other favorite siding options like aluminum, vinyl and wood composite materials.

Although fiber cement siding has many advantages, the intricacy involved in installation makes it one of the most complicated and demanding materials to work with. Because of this, the role of the contractor is very important to ensure the stability of structures made out of fiber cement. Discover the properties of fiber cement and learn why a reliable contractor is important to ensure its performance.

Quality and Properties of Fiber Cement

Fiber cement for siding comes in many types depending on the width and the design. Most fiber cement siding are differentiated by brand name. But the basic properties that add to the resistance of fiber cements falls on the quality of the product. Top quality fiber cement must be made using industry standards: since the fiber cement is made of composite materials, the correct combination and manufacturing process must be followed to ensure their resistance and durability. Fiber cement is often sold depending on how they are shaped, including shingle, shake, lap and vertical siding.

Fiber cement is extremely tough, but they are very fragile and highly prone to breaking and chipping before installation. Through proper installing techniques, thinner or less dense fiber cement siding should also be reinforced to make it more resistant to impact. Installing the siding can be complicated when done alone, which is why it would help to hire contractors for proper and tighter assembly.

Fiber Cement Siding Installation

Fiber cement is usually installed by levels. The alignment is important to make it more water-tight, and nailing techniques will help hide the nail heads and make the panels sounder. Overlapping is the common technique of installing fiber cement, but manufacturers may have specific instructions for installation.

Because of the number of materials needed, installing fiber cement siding takes time. Sheets shaped into certain thicknesses are also cut using specific tools that may not be available in many hardware stores. Installing fiber cement also becomes more complicated once ventilation and flashing are considered. Ventilation and flashing are done to improve the life of the materials and to prevent damage. Contractors are suited to do the job and provide the expertise to assure quality.

The size of these sheets varies from manufacturer to manufacturer and according to the demand and needs. Generally the size of these sheets range from 4′ x 8′ sheets and in lenghts of 6″ by 12′ long.

The thickness of fiber cement boards also varies from manufacturer to manufacture. General width of the fiber cement cladding is about 3/8″. Usually the higher density of the fiber cement cladding having a cleaner edge when cut but the lower density having a rough edge when it cut.

Higher density fiber cement siding is the best product for thermal resistance, sound transition resistance and for wall insulation process. If the product is thicker and denser, better is the thermal resistance and sound transition resistance. Fiber cement siding is a very heavy material so it is very difficult to carry by a single man. Usually two or more men needed to carry this product properly. Before the installation, there are many chances for the breakdown and damage of this product, so you must need to handle it very carefully. It will be easily destroyed if not handle with care.

  • For proper installation of fiber cement siding, you must need to hire a professional siding installer.
  • Fiber cement cladding is a composite material that is made off cement, sand, and cellulose fiber and silica particles. Due to this reason fiber cement siding generate large amount of dust when you cut it into different pieces.
  • The cost of fiber cement siding is also higher than the other siding material available in the market.
  • Fiber cement cladding is more porous than vinyl and other materials available in the market. It absorbs water through the edges.
