Types of Composite Wood Siding

When it comes to composite wood siding, there are several options to choose from. Each type has its unique composition and benefits, making it crucial to understand the differences. Let’s dive into the three main types: Engineered Wood Siding, Fiber Cement Siding, and Wood-Plastic Composite Siding.

Engineered Wood Siding

Engineered wood siding is a popular choice for many homeowners due to its natural appearance and robust composition. It is made from wood fibers that are coated with waxes and resins, then pressed under heat to form durable boards. This process ensures the siding is strong and can withstand various weather conditions.

Natural Appearance: Engineered wood siding mimics the look of real wood, making it an attractive option for those who love the traditional wood aesthetic.
Strength: The resin binder used in the manufacturing process adds strength, making it less prone to breakage compared to other types of siding.
Eco-Friendly: Often made from recycled wood fibers, making it a more sustainable choice.

Maintenance: Although it requires less maintenance than real wood, it still needs periodic painting or staining to maintain its appearance.

Fiber Cement Siding

Fiber cement siding is known for its durability and resistance to various elements. It is composed of cement mixed with cellulose fibers, sand, and water, creating a strong and long-lasting material.

Durability: Highly resistant to fire, insects, and rot, making it one of the most durable siding options available.
Low Maintenance: Requires minimal upkeep, saving you time and money in the long run.
Versatility: Available in various textures and colors, allowing for a wide range of design possibilities.

Weight: Fiber cement siding is heavier than other types, which can make installation more challenging and costly.
Brittleness: While durable, it can be brittle and prone to cracking if not handled properly during installation.

Wood-Plastic Composite Siding

Wood-plastic composite siding combines wood fibers with plastic materials to create a product that offers the best of both worlds. This type of siding often features UltraShield technology, which enhances its durability and appearance.

Durability: Extremely resistant to moisture, insects, and rot, making it ideal for various climates.
Low Maintenance: Thanks to UltraShield technology, this siding requires virtually no maintenance and retains its appearance for many years.
Eco-Friendly: Often made from recycled materials, contributing to a more sustainable environment.

Cost: Generally more expensive than other siding options, but the long-term benefits often outweigh the initial cost.
Appearance: While it mimics the look of wood, some homeowners may find it less natural-looking compared to engineered wood siding.

By understanding the differences between these types of composite wood siding, you can make an informed decision that best suits your home’s needs and your personal preferences. Next, let’s explore the benefits that make composite wood siding a standout choice for homeowners.

Benefits of Composite Wood Siding

Choosing composite wood siding for your home can bring many advantages. Let’s dive into the key benefits that make it a popular choice among homeowners.


Composite wood siding is known for its long-lasting durability. Made from a blend of materials like wood fibers, plastic, and resin, it can withstand harsh weather conditions, including heavy winds and extreme temperatures. This means fewer repairs and replacements over time, saving you money in the long run.

Low Maintenance

One of the standout features of composite wood siding is its low maintenance. Unlike traditional wood siding, it doesn’t require regular painting, staining, or sealing. A simple wash with soap and water is usually enough to keep it looking new. This makes it an excellent option for busy homeowners who want a beautiful exterior without the hassle.

Pest Resistance

Insects like termites and carpenter ants can wreak havoc on wood siding. Fortunately, composite wood siding offers pest resistance. The materials used in its construction are not attractive to these pests, providing an extra layer of protection for your home.

Mold Resistance

Mold and mildew can be a problem with traditional wood siding, especially in humid climates. Composite wood siding, thanks to its mold resistance, doesn’t absorb moisture easily. This reduces the risk of mold growth, keeping your home healthier and more attractive.

Fire Resistance

Safety is always a concern, and composite wood siding offers fire resistance. Unlike natural wood, which can be highly flammable, composite materials are designed to withstand high temperatures. This added layer of safety can give you peace of mind, especially if you live in an area prone to wildfires.

Fade Resistance

Exposure to the sun can cause many siding materials to fade over time. Composite wood siding, however, boasts fade resistance. Advanced manufacturing techniques ensure that the color remains vibrant for years, reducing the need for repainting and keeping your home looking fresh.

Stain Resistance

Accidents happen, and spills are inevitable. Whether it’s wine, coffee, or oil, composite wood siding offers stain resistance. The protective layer on the surface prevents liquids from being absorbed, making it easy to clean up any messes and maintain the siding’s appearance.

By opting for composite wood siding, you’re investing in a durable, low-maintenance, and aesthetically pleasing exterior for your home. Next, we’ll guide you through the installation process to ensure a successful project.

Installation Process

Step-by-Step Installation Guide

Installing composite wood siding can be straightforward if you follow the right steps. This guide will walk you through the process, from planning to final touches.

Local Building Codes

Before starting, research local building codes. These regulations will guide you on requirements or restrictions for siding. Compliance ensures safety and avoids legal issues.

Safety Gear

Safety is paramount. Wear appropriate gear: pants, gloves, long sleeves, safety glasses, and respiratory protection. This minimizes the risk of injury during handling, cutting, or installing the siding.

Suitable Tools

Use standard woodworking tools for installation. For cutting, carbide-tipped blades are recommended. Use stainless steel screws or properly coated deck screws to avoid corrosion and achieve the best results.


Proper ventilation is crucial. Composite siding should not be installed directly on a flat surface. Instead, attach it to a substructure that allows for unobstructed airflow. Leave at least an inch of free space under the siding to prevent moisture buildup.


When fastening, ensure screws are driven at a 90-degree angle to the surface. Avoid toe-nailing. If a 90-degree angle isn’t possible, add an extra joist.


Use aluminum joists or pressure-treated wood for the substructure. Space the joists no farther apart than 1.64 feet on center to support the siding properly.

Site Plan

Prepare a site plan before starting. This will help you visualize the layout and ensure you have the right amount of materials. Submit the plan to your local building department for approval.

Vapor Barrier

Install a breathable vapor barrier behind the joists. This allows proper air flow and prevents moisture from getting trapped, which can cause mold and structural damage.


Add insulation behind the vapor barrier to improve energy efficiency. This keeps your home warm in the winter and cool in the summer.

Expansion Gaps

Composite wood siding expands in warm temperatures and contracts in cold. Leave an expansion gap between boards. For example, leave a 2/16-inch gap if installing an 8-inch board at 32°F, and a 1/16-inch gap at 68°F.

Static Minimization

In high-altitude areas with low humidity, static can be an issue. Avoid using metal railings or chairs near the siding to reduce the chance of shocks. An anti-static mat by the doorway can also help.

By following these steps, you can ensure a successful and long-lasting installation of your composite wood siding. Next, we’ll explore the environmental impact of using composite wood siding.

Environmental Impact

When choosing composite wood siding, it’s important to consider its environmental impact. Let’s dive into how this material stands out in terms of eco-friendliness.

Recycled Materials

One of the key benefits of composite wood siding is its use of recycled materials. For instance, companies like NewTechWood use up to 95% recycled content in their products, including plastic bottles and reclaimed wood fibers. This practice not only diverts millions of pounds of plastic from landfills each month but also ensures that high-quality materials are used in production.

Reduced Carbon Emissions

Composite wood siding manufacturers are committed to reducing their carbon footprint. By minimizing waste and conserving energy, they ensure that their production processes are as efficient as possible. Additionally, these companies often undergo yearly audits by third-party organizations to ensure compliance with environmental regulations, further reducing their overall carbon emissions.

Eco-Friendly Production

The production methods for composite wood siding are designed to be eco-friendly. For example, NewTechWood has been following green manufacturing techniques for nearly three decades. These methods include:

  • Controlled Recycling Processes: Ensuring only the highest-quality materials are used.
  • Energy Conservation: Using efficient production processes to minimize energy consumption.
  • Waste Minimization: Reducing waste during manufacturing to lessen environmental impact.

Green Manufacturing Techniques

Green manufacturing techniques are at the heart of producing composite wood siding. These techniques focus on three main pillars of green living: environmental protection, social development, and economic development. By adhering to these principles, manufacturers can create products that are not only durable and low-maintenance but also sustainable.

In summary, choosing composite wood siding means opting for a product that supports environmental sustainability. From using recycled materials to employing eco-friendly production methods, this siding option is a smart choice for environmentally-conscious homeowners.
