Exterior Building Components

Avient's material solutions help bring strength, durability, and design flexibility to every exterior surface.

Avient delivers advanced composite solutions and a high-performance portfolio of colorants, UV stabilizers, and additives engineered specifically for exterior building manufacturers. Our materials solutions can help manufacturers achieve enhanced durability, consistent aesthetics, and long-term performance across every component of the building envelope, while integrating seamlessly into existing production processes.

Which Building Components Can Benefit from Avient Composite and Polymer Solutions?

Avient's material solutions are engineered for every major component of the exterior building envelope, including:

  • Exterior wall systems and cladding
  • Garage doors and overhead panels
  • Roofing systems and underlayment components
  • Outdoor decking and structural flooring
  • Fascia, trim, and framing profiles

Why Replace Traditional Metal and Wood with High-Performance Composites and Polymers?

Traditional materials like steel, aluminum, wood, and OSB can each carry inherent performance limitations that high-performance composites and polymers are engineered to overcome.

  • Replace heavy metals: Steel and aluminum components are prone to denting, corrosion, and rust — particularly in coastal and high-humidity environments. Avient's composite and polymer solutions deliver equivalent or exemplary structural performance at a fraction of the weight, eliminating the maintenance burden and lifecycle costs associated with metal building products.
  • Replace wood and OSB: Wood-based materials are susceptible to moisture absorption, warping, rot, and insect damage. Avient's composites resist moisture, dimensional change, and environmental degradation while delivering the natural look of wood grain without the ongoing maintenance.
  • Lightweight construction advantage: Avient composite materials are significantly lighter than traditional metal alternatives, enabling easier installation, lower transportation costs, and improved energy efficiency for building system designs.

What Performance Technologies Can Be Built Into Avient's Composite and Polymer Solutions?

Avient's exterior building materials incorporate multiple engineered performance technologies in a single material system:

  • UV stabilizers can reduce the degradation caused by ultraviolet radiation, helping exterior building components maintain color fidelity, surface integrity, and structural performance over extended outdoor exposure. UV stabilization is critical for roofing, decking, and cladding applications where long-term color retention is a specification requirement.
  • Antimicrobial technologies can be formulated to limit the growth of bacteria, mold, and fungi on composite surfaces. This technology is particularly important for outdoor decking, garage door panels, and exterior wall systems in humid climates where biological growth accelerates surface degradation.
  • Laser marking capability can enable manufacturers to add permanent part identification, regulatory markings, barcodes, and decorative surface detail with high precision and production-line repeatability. Laser marking eliminates the consumables and messy cleanup associated with inkjet or pad printing systems.
  • Colorants and aesthetic additives can help manufacturers achieve consistent color matching, custom finishes, and specialized surface effects — including wood-grain textures, matte and gloss finishes, and fade-resistant exterior color palettes — across all major composite processing methods.

Which Manufacturing Processes Are Compatible with Avient's Composite Solutions?

Avient solutions are designed for seamless integration into leading composite manufacturing processes used across exterior building applications. Compatible processes include:

  • Extrusion – decking boards, trim profiles, siding panels
  • Co-extrusion – capped composites, multi-layer wall panels
  • Compression molding – garage door skins, structural panels
  • Pultrusion – structural profiles, door frames, composite rebar

What Sets Avient Apart:

Avient combines a customizable materials portfolio with deep application engineering expertise to help exterior building manufacturers solve complex design, performance, and processing challenges. From material formulation to production support, we collaborate every step of the way.

  • Application-specific formulations: Avient can engineer solutions for your specific substrate, manufacturing process, and performance requirements — not off-the-shelf approximations.
  • Multi-technology integration: UV stabilization, antimicrobial protection, laser-marking capability, custom colorants and other performance-enhancing technologies can be combined into a single material solution, reducing the number of suppliers and simplifying your supply chain.
  • Process compatibility: Avient solutions are qualified for extrusion, co-extrusion, compression molding, and pultrusion — covering the full range of exterior composite manufacturing processes.
  • Technical support: Avient's application engineers provide on-site and remote support material qualification, process optimization, and new product development.

Highlights:

  • Materials offer excellent strength-to-weight ratio compared to traditional siding materials
  • Optimization additives act as cycle-time reducers, helping improve production efficiency while enhancing dimensional stability and energy efficiency
  • Halogen-free flame-retardant technologies meeting E84 Class A, B, and C fire safety standards
  • Up to 60% improvement in dent resistance compared to unreinforced metal for doors and cladding applications
  • Chemical foaming agents to reduce weight and density without compromising mechanical properties
  • FX special effect colorants offer granite, marble, and woodgrain appearances, while stain colorants provide unique surface effects
