What You'll Learn
Vinyl siding is made from polyvinyl chloride (PVC)
Vinyl siding is a popular choice for the exterior of homes, and for good reason. It is made from polyvinyl chloride (PVC), a type of plastic that offers a range of benefits. Firstly, vinyl siding is known for its durability and low maintenance. The PVC material is scratch-resistant due to the colourants added to the mixture, making any scratches practically invisible. Additionally, it is decay-proof and will not rot or flake, ensuring a longer lifespan compared to natural materials like wood.
Vinyl siding is also designed to be both rigid and flexible, thanks to the addition of plasticizers. This flexibility is crucial for installation and allows the siding to withstand wind speeds of up to 110 mph when properly installed. The siding is manufactured by co-extrusion, with two layers of PVC laid down in a continuous process. The top layer, known as the capstock, makes up about 25% of the siding thickness and provides weatherability and durability. It often contains titanium dioxide, which offers resistance to UV light breakdown.
The remaining 75% of the siding is made up of a lower layer called the substrate, typically consisting of ground limestone (calcium carbonate). This layer helps to reduce costs and maintain fluidity during manufacturing. Vinyl siding also comes in a wide range of colours, styles, and types, making it a versatile option for homeowners. However, it is important to note that vinyl siding has faced environmental and health concerns due to the additives used, such as the plasticizer DEHP.
Despite being one of the most widely produced plastics globally, PVC siding has faced criticism for its sustainability. Nevertheless, vinyl siding remains a popular choice due to its affordability and the wide range of options available. Thicker vinyl products tend to be more expensive but offer greater rigidity and aesthetic appeal, potentially increasing impact resistance. Overall, vinyl siding, made from PVC, offers a combination of durability, flexibility, and customisation options that have contributed to its widespread use.

Polymer siding is made from polypropylene resin
Polymer siding is a type of plastic siding made from polypropylene resin. It is a fairly new material on the market that is becoming popular due to its versatility and affordability. It is made using an injection moulding process, which allows for a wide range of styles, textures, colours, and sizes. This process also gives the final siding a three-dimensional pattern.
Polypropylene resin is a type of plastic with a chemical makeup that contributes to polymer siding's impressive durability, impact resistance, and heat resistance. It is quite flexible, allowing polymer siding to be easily moulded to resemble real wood or stone. This flexibility also enables it to be used in creating custom shapes like shingle or shake cladding. The resin hardens once it cools down, making it one of the hardest materials in the industry.
Polymer siding offers many benefits to homeowners. It is strong and impact-resistant, with triple the impact resistance of vinyl siding. It will not warp, crack, chip, fade, or peel, even during severe wind storms. It is also energy-efficient, as it comes with a layer of form-fitted insulation that reduces heat transfer. This helps stabilize indoor temperatures and reduces the burden on HVAC systems.
Polymer siding is more environmentally friendly than vinyl siding during the production process. Polypropylene resin contains only two elements, hydrogen and carbon, making it a more neutral plastic. In contrast, vinyl siding is made from polyvinyl chloride (PVC) resin, which contains chlorine and produces toxins when incinerated. The production of PVC has also raised environmental and health concerns.

Vinyl siding is widely available and affordable
Vinyl siding is made of polyvinyl chloride (PVC) resin, a type of plastic. It is one of the most widely produced siding options globally and is well-loved for its versatility and affordability.
Vinyl siding is widely available due to its high production rate. It is the most commonly installed exterior cladding for residential construction in the United States and Canada. Its popularity is attributed to its affordability, low maintenance, and ability to be customised to resemble other materials like wood or stone.
Vinyl siding is affordable because it requires less energy to produce compared to other alternatives. The limestone in its composition reduces cost while also balancing the titanium dioxide content. The thickness of vinyl siding also affects its cost, with thicker grades typically being more expensive. However, the chemical makeup of vinyl siding may have a greater impact on its durability than its thickness.
The affordability of vinyl siding can be further enhanced by choosing standard colours and styles, as custom options tend to be more expensive. Proper installation is also crucial to ensuring that poor materials or workmanship do not lead to higher long-term expenses.
Vinyl siding is available in a wide range of colours, styles, and product qualities. It is designed to be rigid while maintaining flexibility due to the addition of plasticizers. The colourants added to the PVC mixture protect the siding from scratches, making it low-maintenance. Its flexibility allows for easy installation, and its long lifespan reduces the need for frequent replacement.

Polymer siding is environmentally friendly
Polymer siding is made from polypropylene resin, a type of plastic. While vinyl siding is also made of plastic, it is made from polyvinyl chloride (PVC). The different chemical makeup of polypropylene resin makes polymer siding more environmentally friendly than vinyl siding.
The production process of polymer siding is more environmentally friendly than that of vinyl siding. Polypropylene resin is a more neutral plastic and is better for the environment. PVC production, on the other hand, has raised environmental and health concerns. For example, the use of additives like the plasticizer DEHP and the release of hydrochloric acid during the aging of PVC have been flagged as potential risks.
Polymer siding is also more durable than vinyl siding. It can withstand high heat and maintain its shape, resisting warping and cracking. Polymer siding is also stronger than vinyl siding of the same thickness due to its complex molecular bonding. This makes polymer siding a more long-lasting option, with a maximum life of 60 years compared to 40 years for vinyl siding.
Additionally, polymer siding offers greater insulation and is more energy-efficient than vinyl siding. The improved insulation helps stabilize indoor temperatures and reduces the burden on HVAC systems, leading to lower energy bills.
However, it is important to note that polymer siding is more expensive than vinyl siding, with costs up to twice as much. The higher cost of polymer siding is due to its longer lifespan and superior durability, but it may not offer significantly more features than vinyl siding.

Vinyl siding is low-maintenance
Vinyl siding is made from polyvinyl chloride (PVC) resin, a type of plastic. It is a popular choice for the exterior of homes and small apartment buildings, used for decoration and weatherproofing.
Vinyl siding is a low-maintenance option for those looking to save time and money. Unlike wood siding, which needs to be scraped, painted, and repaired, vinyl siding is easy to maintain. It only requires occasional cleaning with soap, water, or a mild detergent about once or twice a year. A soft brush and a hose can be used, and a mild detergent can be added for dirtier areas. A good rainfall can also wash away dirt and debris, and its slick surface means most debris and cobwebs can be removed with water alone.
Vinyl siding is also naturally fire-resistant and repels moisture, rot, and insects, providing an extra layer of protection for your home. It is scratch-resistant, as the colour runs through the PVC mixture, making scratches practically invisible. It is also decay-proof, resulting in a longer lifespan than natural options such as wood.
However, vinyl siding is susceptible to damage from high heat, hail, and excess water. It can warp in hot temperatures and crack in cold weather when struck by a hard object. Vinyl siding is also not considered environmentally friendly, and there are few places that will accept it for recycling.
Overall, vinyl siding is a cost-effective, low-maintenance option for those looking to avoid the constant upkeep required by other siding materials.
