Custom Extruded Thermoplastics in Modern Architecture and Building

Custom extruded thermoplastics are prominent in modern architecture because of their versatility, durability, and aesthetic flexibility. They offer both practical benefits and design flexibility. These materials are used in many essential building components, such as weather stripping, trim, molding, seals, tubing, and fittings. They are also used in decorative pieces.

The extruded plastics market is expected to grow from $240 billion in 2023 to nearly $263 billion by 2030. The growth is expected to be driven by the construction industry, which is seeing an increased demand for extruded plastic products. Extruded thermoplastics can be molded into any shape from various materials, making them ideal for creating custom solutions for each project. They are also manufactured with high precision, so they fit together seamlessly.

This blog post will explore how custom-extruded thermoplastics are used in modern architecture. We’ll look at how these extruded parts are used to protect, enhance, and refine the buildings we live and work in. We will also explore materials selection and design considerations for creating parts that function as intended within these buildings.

How Custom Extruded Thermoplastics are Used

From highly functional to highly decorative, custom extruded thermoplastic is found throughout residential and commercial buildings. Some examples of where they are used include:

• Doors and windows – Frames, gaskets, weather stripping, and decorative moldings
• Garage Doors – Weatherstripping, trim, molding, seals, or decorative pieces
• External – siding, trim, roofing membranes, gutters, and poles and shapes for fencing
• Plumbing and HVAC – Tubing, pipes, fittings, trim case, kickplates
• Electrical – coverings for wire and cables, lighting fixtures
• Other uses – thresholds, baseboards, flooring, shower seals, decorative elements

Material Characteristics and Benefits

Thermoplastics have long been used in building designs because of their many beneficial characteristics. Thermoplastics offer a wide range of characteristics that allow for versatility in design. Many have a high strength-to-weight ratio, resist weathering, and have desirable thermal insulation properties. The characteristics are dependent on the type of plastic used.

The application will determine which characteristics are most important. Some factors to consider when choosing a thermoplastic for a particular product:

• Strength and durability
• Weather resistance
• Chemical resistance
• Flexibility
• Cost

PVC is one of the most versatile and widely used thermoplastics in the construction industry. It is known for its durability, weather resistance, and low cost. PVC extrusion products are used in a wide range of applications, including plumbing and drainage pipes, siding and window frames, roofing membranes, electrical insulation, and flooring.

Acrylonitrile butadiene styrene (ABS) is a strong and impact-resistant thermoplastic resistant to chemicals and corrosion. ABS extrusion products are used in a variety of applications, including drain and waste fittings, vent pipes, roof vents, gutters and downspouts, and door frames and casings.

High-impact polystyrene (HIPS) is a lightweight and durable thermoplastic known for its good impact resistance and formability. HIPS extrusion products are used in various applications, including siding and window trim, soffits and fascia, door and window profiles, decorative molding, and rain gutters.

Polycarbonate is a strong, transparent thermoplastic that is highly impact-resistant and weatherable. Polycarbonate extrusion products are used in a variety of applications, including skylights and greenhouses, window glazing, sound barriers, and safety guards.

Polyethylene (PE) is a family of thermoplastics that are known for being lightweight, flexible, and chemical resistant. PE extrusion products are used in many applications, including vapor barriers, geomembranes, irrigation pipes, and electrical insulation.

Polypropylene (PP) is a lightweight and durable thermoplastic that is also resistant to chemicals and moisture. PP extrusion products are used in a variety of applications, including drainage pipes, plumbing fittings, vents and ducts, electrical insulation, and flooring.

Design Freedom and Aesthetics

One of the biggest benefits of extrusion is that the process allows for the creation of complex cross-sectional profiles, which can be designed to architects’ exact specifications.

Thermoplastics can be extruded into a wide array of shapes, sizes, and colors as well as textured, embossed, and printed to create unique and visually appealing finishes, allowing architects and builders to implement bold and unique visual statements.

In addition to some traditional uses, custom extrusion allows architects and builders to create solutions for design challenges, such as aerodynamic air ducts for ventilation systems, curved and angled siding to create unique architectural features, or sound-absorbing panels to improve acoustics in rooms.

Technical Considerations in Construction

Before architects, builders, or designers jump into designing custom extrusions, there are some technical considerations that they should be aware of in addition to material choice. Other factors to consider include:

• Cross-section design: The cross-section design of the component will affect its structural properties, such as strength, stiffness, and weight. It can also impact the fit and function, particularly if it must fit into another component or create a seal. It is important to design the cross-section carefully to ensure the component meets the required performance specifications.
• Manufacturing tolerances: Plastic extrusion is a manufacturing process with inherent tolerances. It is important to be aware of these tolerances when designing the component and to ensure that they are within the acceptable range for the application.
• Joint design: If the component will be joined to other components, it is essential to design the joint carefully to ensure that it is strong and durable. It is also important to consider how the parts will be joined (e.g., hardware, adhesive, etc.) and if that impacts the cross-section design.
• Assembly considerations: If the component will be assembled with other components, it is crucial to consider the assembly process when designing it. This includes factors such as alignment, fastening, and sealing.
• Cost: The cost of custom extruded plastic components can vary depending on the complexity of the design, the thermoplastic used, and the quantity required. It is important to factor in the cost when designing the component.
