Acrylic is another clear plastic building material commonly used for skylights, canopies, signage, and decorative glazing. It offers excellent clarity, a glossy appearance, and good weatherability.

When you need lightweight plastic alternatives to glass with strong visual appeal, acrylic sheets are a popular option. Laird supplies acrylic materials through its Acrylic Sheets category.

FRP Wall Panels: Hygienic and Easy-to-Clean Surfaces

Fiber-reinforced plastic (FRP) wall panels are widely used in commercial kitchens, food processing plants, restrooms, and healthcare facilities. They create smooth, easy-to-clean surfaces with excellent moisture and impact resistance.

These FRP wall panels for commercial buildings often meet strict codes for hygiene and durability, making them ideal for high-traffic and wash-down environments.

EPS and Other Plastic Insulation Materials

Expanded polystyrene (EPS) and other plastic insulation systems contribute to the building envelope by improving thermal and acoustic performance. They are used in roofing systems, wall assemblies, and under-slab insulation.

These plastic materials for construction help reduce energy consumption while maintaining comfort and limiting thermal bridging.

Aluminum Composite Panels (ACM) and Hybrid Systems

Aluminum composite panels (ACM) combine aluminum skins with a plastic core to create lightweight, rigid panels used for cladding, façades, and signage. They are widely used in modern architecture due to their flatness, durability, and design flexibility.

Laird supports façade and cladding projects through its Aluminum Composite Panels (ACM) offering, helping designers and contractors specify the right panel systems.

Advantages of Using Plastics for Construction

Advantages of Plastic Building Materials vs. Traditional Materials

The advantages of plastics as building materials are driving their adoption across commercial, industrial, and even residential projects. When compared to glass, metal, or wood, plastics often deliver better value on a lifecycle basis.

Key advantages of plastics in construction include:

  • Lightweight: Easier and safer to handle on the jobsite, reducing structural loads and installation time.
  • Impact resistance: Polycarbonate and certain composites outperform glass and brittle materials when struck.
  • Corrosion resistance: Plastics do not rust, making them ideal for damp or chemically aggressive environments.
  • Design flexibility: Plastics can be formed, cut, routed, and thermoformed into complex shapes and curves.
  • Thermal and acoustic performance: Many plastic systems help with insulation and noise control.
  • Lower maintenance: Smooth, non-porous surfaces are easier to clean and maintain over time.

These properties make construction plastics a strong choice for glazing, interior protection, and exterior cladding where performance and long-term value matter.

Are Plastics a Good Choice for Sustainable Construction?

Did You Know Plastics In Construction

Choosing the Right Plastic for Your Construction Project

With so many types of plastics used in construction, the best way to select a material is to start with performance requirements. Ask what the surface needs to resist and how it will be installed and maintained over time.

Key questions to guide material selection:

  • Is impact resistance more important than scratch resistance?
  • Will the material be exposed to UV, chemicals, or frequent cleaning?
  • Is clear visibility required, or is the panel mainly structural or decorative?
  • What fire ratings, codes, or certifications apply?
  • How important are weight and ease of installation?

For example, polycarbonate panels for construction are often best for high-impact glazing, while acrylic sheets may be chosen for high-clarity skylights and signage. FRP wall panels fit harsh, hygienic interiors, and HDPE sheets suit high-wear or corrosive environments.
