Upgrading a home’s exterior with new siding can provide aesthetic benefits, but it can also significantly improve energy efficiency. Proper installation of siding enhances insulation, leading to reduced energy costs and a more comfortable indoor climate.

Homeowners considering siding installation should understand the options like vinyl, fiber cement, and engineered wood. Work with an experienced professional to select materials that suit your climate and complement your home’s architecture.

Careful installation and strategic use of insulation under new siding can reduce air leaks and improve energy performance. With the right materials and proper technique, a siding upgrade can make your home more beautiful while cutting energy bills.

What Is Siding Installation and How Does It Impact Energy Efficiency?

Siding installation involves replacing or repairing exterior siding on homes. New siding can significantly improve a home’s energy efficiency, as older siding may be damaged or allow air infiltration. Properly installed siding creates an effective weather-resistant barrier and insulation for homes.

Types of Siding

The most common types of siding for homes are vinyl, fiber cement, and wood. Vinyl siding is inexpensive but not very durable. Fiber cement siding is more durable and fire-resistant but also more expensive. Wood siding requires ongoing maintenance like staining and sealing but can have a natural wood appearance. For energy efficiency, vinyl and fiber cement siding are good options as they provide an effective weather barrier.

How Siding Improves Energy Efficiency

New siding installation involves sealing and weatherizing the entire exterior of the home. Gaps or cracks in walls, attics, basements, and roofs are located and sealed to reduce air leakage. Insulation may also be added behind the new siding to improve the home’s R-value, which measures resistance to heat flow. Together, these weatherization and insulation measures can significantly reduce utility costs and improve comfort inside the home.

What is Siding on a House?

Siding refers to the exterior material installed on the walls of a house. Common types of siding include vinyl, aluminum, wood, brick, and stone. Siding protects the structure from environmental damage while also impacting a home’s appearance and energy efficiency.

Vinyl Siding

Vinyl siding is a popular, low-maintenance option made of PVC plastic. It is durable yet lightweight, resistant to weather, and available in a variety of styles resembling wood or stone. However, vinyl siding lacks breathability and insulation. Installing vinyl siding can increase a home’s energy efficiency by up to 20% if existing siding is badly damaged or missing.

Aluminum Siding

Aluminum siding is another low-maintenance siding made of aluminum panels. It is corrosion-resistant, durable, and recyclable. However, aluminum is an excellent conductor and does not insulate well. Aluminum siding may reduce heating/cooling costs by 10% compared to uninsulated walls but less than more insulating siding types.

Wood and Composite Wood Siding

Wood siding, such as cedar and redwood, is attractive and natural. However, it requires frequent maintenance to prevent rot and insect damage. Composite wood siding, made of wood fibers and plastic, has the appearance of wood with lower maintenance. Both provide good insulation and can improve efficiency by up to 30% compared to uninsulated walls.

Types of Siding That Improve Insulation

Installing residential siding that provides effective insulation is one of the best ways a homeowner can increase energy efficiency and lower utility bills. There are several siding options suited for this purpose.

Vinyl Siding

Vinyl siding is an affordable and low-maintenance siding material that offers insulation. It is made from polyvinyl chloride (PVC) plastic and comes in a variety of styles that mimic the appearance of wood or masonry. Vinyl siding panels help insulate by trapping air in pockets within the material. They provide an R-value of around R-3 per inch of thickness.

Fiber Cement Siding

Fiber cement siding is a durable siding option made from sand, cement, and wood fibers. It is resistant to rot, insects, and fire. Fiber cement siding can also improve home insulation with an R-value between R-2 to R-3 per inch. It is available in a variety of styles, including shingles, planks, and panels.

Insulated Vinyl Siding

For the highest insulation, insulated vinyl siding is an excellent choice. It features a layer of insulating foam adhered to the back of the vinyl panels. This provides an additional R-3 to R-7 per inch of insulation. Insulated vinyl siding comes at a higher cost but can significantly improve the energy efficiency of a home.

Evaluating Your Home to Determine the Best Siding Option

To choose the most energy-efficient siding for a home, several factors must be considered. The home’s location and climate are important, as materials that insulate well in cold weather may cause overheating in warm weather. The home’s existing siding and wall structure must also be evaluated.

Climate Considerations

In colder climates, siding options like vinyl, insulated steel, and fiber cement may be good choices, as they provide more insulation than wood or brick. In warmer areas, siding that reflects heat, such as light-colored painted metal or vinyl, can help lower cooling costs. For the widest range of climates, impact-resistant fiber cement siding may be ideal.

Existing Wall Structure

The condition and type of a home’s current siding and sheathing should be assessed. If there is water damage or rot, it must be repaired before new siding is installed. The sheathing, or boards under the siding, also affect choices. Sheathing that is warped or damaged will telegraph through to the new siding. homes with little or no sheathing may require strapping or wood planks to be installed before new siding.

Siding Options Pros and Cons

The pros and cons of siding types like vinyl, wood, stone, brick, or fiber cement should be weighed based on a home’s specific needs. For example, while vinyl siding is affordable and low-maintenance, it may not suit homes in very hot climates. Wood siding is appealing but requires frequent maintenance. Fiber cement provides the look of wood with lower maintenance. By evaluating climate, existing walls, and siding types, homeowners can determine the most energy-efficient and cost-effective siding for their homes.

Hiring the Right Siding Installation Contractor

Hiring a qualified siding installation contractor is crucial to ensure proper installation and maximum energy efficiency. Homeowners should conduct thorough research to find contractors experienced in their siding material of choice.

Look for contractors with at least five years of experience installing the specific type of siding you want, such as vinyl, wood, or fiber cement. Ask for references from previous clients with homes similar in size and style to your own. Contact references to ask about the quality of work, timeliness, and budget.

Choose a contractor with proper licensing and insurance for siding installation in your area. Proper licensing and insurance protect homeowners in case of injury or damage during installation. Ask for proof of both the contractor’s license and insurance before signing a contract.

FAQs About Siding Installation

What types of siding are available?

The three most common types of siding are vinyl, fiber cement, and wood. Vinyl siding is low-maintenance but can look artificial. Fiber cement siding has the appearance of wood but requires painting. Wood siding, such as cedar or redwood, provides an attractive natural look but requires ongoing maintenance like staining or painting.

How long does the siding installation take?

The time required for siding installation depends on several factors, including the square footage of the home, the number of stories, and the type of siding. On average, vinyl siding installation takes 2 to 3 days for a typical single-family home. More intricate siding like wood or fiber cement may require 3 to 5 days. The installation time also does not account for any necessary repairs to the underlayment or trim that may be needed.

How much does the siding cost to install?

Siding installation costs vary significantly based on the home’s size and the materials used. On average, homeowners pay between $10,000 to $20,000 for siding installation. Vinyl siding is typically the most affordable at $3 to $7 per square foot. Wood and fiber cement sidings tend to cost $6 to $10 per square foot. Additional costs include trim, underlayment, and installation fees which can add $3 to $5 per square foot overall. Premium grades or intricate designs of any siding type will be on the higher end of the cost spectrum.

Will new siding increase home value?

Yes, installing new siding can increase a home’s value, especially if the current siding is damaged or an outdated material. Attractive, low-maintenance siding like vinyl or fiber cement provides good curb appeal and can boost a home’s value by 3% to 5% according to industry estimates. High-quality wood siding may increase value even more, around 5% to 8% due to its natural, custom appearance. However, siding alone typically will not significantly increase a home’s value without other upgrades.


In conclusion, the importance of choosing an energy-efficient siding installation cannot be overstated. By selecting materials with optimal insulation properties and working with experienced contractors who follow best practices, homeowners can dramatically reduce wasted energy and utility costs.

The investment into high-performance siding will pay dividends for years through improved home comfort and reduced environmental impact. With careful planning and research, homeowners can make their home exteriors a source of efficiency rather than an energy drain.
