What is under aluminum siding

When it comes to siding, aluminum is one of the most popular options. It's durable, easy to maintain, and comes in a variety of colors and styles. But what is under the aluminum? What are you actually getting when you install aluminum siding on your home?

In this blog post, we will take a closer look at the materials used in aluminum sidings and discuss whether they are worth the investment.

How is aluminum siding made?

Aluminum siding is made of two pieces of aluminum bonded together with an adhesive. The bottom piece is called the base sheet, and the top piece is called the finished sheet.

The base sheet is made of a strong, durable aluminum alloy that can withstand high temperatures and pressure. It is then coated with a layer of primer that helps the finished sheet adhere to the base sheet.

The finished sheet is made of a softer, more malleable aluminum alloy. It is then coated with a layer of paint or vinyl that gives it the desired color and finish.

Once the two sheets are bonded together, they are cut into long strips that are installed on the home's exterior.

What Is Underneath Aluminum Siding?

There are three main materials that are used under aluminum siding:

1. Plywood

Plywood is a type of wood that is made by bonding together several thin sheets of wood. It is strong and durable, making it an ideal siding material.

Plywood is often used as the base sheet in aluminum siding. The plywood is first attached to the house with nails or screws. Then, the aluminum siding is installed over top of the plywood.

Plywood is susceptible to rot and insect damage. However, you can easily prevent these problems by regularly inspecting your plywood for signs of damage. If you see any cracks, holes, or warping, it is essential to repair them immediately.

2. Oriented Strand Board (OSB)

Oriented Strand Board is a type of engineered wood made by compressing and bonding strands of wood. OSB is typically used as a subfloor or sheathing material. It is also sometimes used under the aluminum siding.

OSB consists of layers of wood that are oriented in different directions. This gives the board strength and stability. OSB is a cheaper alternative to plywood and can be used for various purposes.

Some people worry that OSB will absorb moisture and rot. However, OSB is treated with chemicals that make it resistant to moisture and mold.

3. Fiber Cement Board

One of the most common materials used as a backing for aluminum siding is fiber cement board. Fiber cement board is made from a mix of wood pulp, Portland cement, and silica sand. It is then formed into thin boards that are about ¼ inch thick. The boards are then coated with acrylic resin to make them waterproof and insect resistant.

Fiber cement board is a durable material that can withstand a lot of wear and tear. Also, it is not susceptible to rot or insect damage. Fiber cement board is also easy to install and is available in a variety of thicknesses.

Are Aluminum Sidings Worth It?

Aluminum siding is a popular choice for homeowners for several reasons:

  1. It is durable and easy to maintain: Aluminum siding is a very strong and durable material. It can withstand high temperatures and pressure, making it ideal for homes in harsh climates. Aluminum siding is also easy to maintain. It does not require painting or staining and is resistant to rot and insect damage.

Aluminum siding is an excellent choice for homeowners looking for a durable, low-maintenance option. It is also a good choice for homeowners who want to be able to easily replace damaged panels. However, it is essential to remember that aluminum siding can be expensive to install. Also, if your home is not adequately insulated, aluminum siding can make it challenging to regulate the temperature inside your home.

If you are considering aluminum siding for your home, it is essential to consult a professional siding contractor to get an accurate estimate of the costs. They will also be able to advise you on whether or not aluminum siding is the best option for your home.
