If you’ve been looking at siding possibilities, you’ve almost certainly come across polymer siding. However, polymer siding isn’t as well-known as other cladding options, partly because it hasn’t been on the market as long as those options. It provides several advantages to today’s homeowners.

On the other hand, Polymer Siding has a lot of benefits and very few disadvantages. So, let’s take a look at the benefits and drawbacks of Polymer Siding in a nutshell. Before you use this incredible material, you should learn everything you can about it.

Polymer siding is a designed type constructed of polypropylene resin, a tough plastic. Polypropylene resin is a versatile material with several commercial and industrial applications.

Polypropylene is usually regarded as a safe material to use. It is completely harmless. Ordinary siding is less durable, requires less care, is easier to install, and is heat resistant. In today’s world, polymer siding is popular.

What Is The Main Difference Between Polymer And Vinyl Sidings?

Because they have a similar appearance, many people confuse polymer siding with vinyl siding. The primary distinction between Polymer and vinyl siding is the material used. Vinyl siding is made of polyvinyl chloride resin, whereas polypropylene siding is made of polypropylene resin.

Vinyl is a type of Polymer that is used to make plastics. The two fundamental constituents of polypropylene resin are hydrogen and carbon, making the material more neutral.

Vertical or horizontal vinyl siding is the most common. You can now construct polymer siding that looks similar to shingle or shake cladding, but where Polymer shines is in custom molded designs that mimic other building types like shingle or shake cladding.

The manufacturing method is another distinction between polymer and vinyl siding. Polymer is molded into three-dimensional designs with a variety of textures and sizes. Vinyl siding is available in only two styles: vertical and horizontal.

Polymer siding is more durable than vinyl siding, which is why people like it. The siding is made of polypropylene resin, which lasts for years and does not need to be maintained every month. They’re simple to clean and don’t need to be regularly re-caulked, re-sealed, or re-painted.

Advantages Of Polymer Sidings

This siding option is highly sturdy and capable of withstanding high heat because of polypropylene resin’s unusual chemical makeup.

Furthermore, it keeps its shape under all conditions, including impact and warping. Polymer siding is made in an environmentally safe manner, and the molding process allows the material to resemble traditional materials such as wood closely.

Highly Durable

After cooling, the polypropylene resin solidifies. You can expect polymer siding to survive for years, if not decades, after a professional finish installing it. Polypropylene resin is one of the industry’s toughest materials, making polymer siding the toughest and most durable option.

They are resistant to cracking, chipping, peeling, warping, and fading. They are also resistant to impacts such as hailstorms and are appropriate for adverse weather conditions.

Custom Appearance

Engineered siding panels come in over a hundred different shapes and patterns. Siding panels of higher quality have three-dimensional grain that resembles natural wood or stone veneers. You can have the polymer siding customized to match the style of your doors and windows if you ask the expert to do so. Or perhaps you have a different design in mind.

These sidings are highly customizable because you can mold them into any shape. Experts can even imitate the look of wood or stone to give the siding a more natural appearance while maintaining its durability and quality.

Because polymer siding is really a 3d cast made from a mold and then painted to add those finishing wood-like touches, it nearly resembles real wood. Because of the aesthetic, it can give your home, whether used throughout or just as an accent piece, it may significantly improve your curb appeal.

Easy To Maintain

Polymer siding’s color is baked in during the manufacturing process. This means the color will last for years without needing to be repainted or cleaned as often. It also keeps the siding looking new without the need for routine maintenance.

The monsoon rain washes away collected dust and dirt from the siding, so you won’t have to spend time physically cleaning it.

The absence of texture on vinyl siding and its seams make it easier to identify. Polymer siding panels, unlike vinyl siding, are frequently made to but up against one other, usually continuing a pattern and texture, making it very difficult to identify the seam.

Easy To Install

Polymer siding is one of the simplest to install compared to other sidings. Because the polymer substance is a cut-and-fold plastic, which can be set up with common tools. Polymer siding is installed in the same way that vinyl siding is. As a result, there is no need for any additional installation instructions.


It might be difficult to make the best decision for your home investment. Is the exterior of your homemade of stone or brick? If so, textural components in your polymer siding are an option. This will give the siding a similar appearance to the exterior of your property. It balances the looks if you use similar hues.

With so many styles to choose from, you’ll have no trouble finding a polymer siding that complements your home. Just make sure it adds to the attractiveness of your home and doesn’t make it appear weird from afar.

If you choose the wrong siding color or design, you risk alienating potential buyers. As a result, while selecting siding, always seek professional assistance.
