Plastic materials are now in widespread use in the construction industry. Why are they selected and what applications are commonplace?

All-Round Properties

Plastic parts are often selected due to their low relative cost. Additionally, they can be far more durable than a lot of metal alternatives. Plastic has been proven to be stronger in many applications and is of course not subject to rusting or corrosion.

In certain applications, plastic can be chosen because of its better insulation properties. This can be particularly advantageous in the construction industry when creating multifamily units, for example. Due to the fact that plastic is generally lightweight it can be easier to install, and this can make for a safer all-round workplace.


When contractors are looking for flooring materials, polyethylene or polyvinyl chloride are great plastic-based solutions. These products have much more resistance to wear and tear and can be cleaned quite easily.


Plastic is used in two separate parts of any roofing process. The surface can be protected from damage by using vinyl on top with polyurethane foam beneath. This will also help to keep the interior of the home more insulated in winter, saving energy.

Interior installation

Inside the home, polyurethane is sprayed as an insulating agent, especially in buildings with high energy-efficiency ratings. This type of foam is thermal resistant and good for maintaining static internal temperatures. From a safety perspective polyurethane is flame retardant and it's also particularly popular because it's both resistant to chemicals and lightweight.

Wall Construction

Interior walls are often made from a composite of expanded polystyrene in between two layers of strand board. This type of structure can be put into place easily and is particularly strong, providing support for columns and other structures within the property.


Lightweight piping is often composed of different plastic products including polyethylene and PVC. Once again, they are easy to install, and they are resistant to water infiltration and chemicals, so they can be used in industrial applications too.

Windows and Doors

Windows often feature polycarbonate due to its lightweight, clear and strong capabilities. They are less prone to breakage and hence popular where security is very important. The frames surrounding the windows can in turn be made from fibreglass or vinyl plastic, with the advantage of being cost-effective, durable and strong.

Finally, the doors on your construction project can also benefit from the wonders of plastic. Polyurethane foam cores can be coated with reinforced plastic to make for a sturdy barrier to entry.
