Certified PIR wall systems for high-performance builds

Big Hands Building Supplies is Sydney’s trusted partner for high-quality, cost-effective materials used in commercial construction and large-scale renovations. We supply polyisocyanurate (PIR) wall solutions for projects that demand thermal efficiency, durability and certified safety.

Our PIR insulation panels are well-suited to various wall applications and meet strict compliance requirements. They’re also supported by aluminium accessories that make installation clean, stable and long-lasting.

What is PIR wall insulation?

PIR wall insulation uses a polyisocyanurate core, known for its thermal resistance and fire-retardant properties. This material helps regulate internal temperature, improve energy efficiency and support compliance with modern building standards. It’s a smart choice for builders seeking high-performance wall systems that reduce energy load and contribute to safer, more comfortable indoor environments.

Our PIR wall solutions include:

• PIR insulation panels — These panels are lightweight and easy to handle. They’re designed to support thermal control and provide a strong, low-maintenance surface for internal or external walls.
  
• Aluminium channels and accessories — We stock a variety of aluminium profiles that support easy installation and a clean finish. These are available in multiple sizes and colours to suit different applications and design preferences.
  

All products are stocked locally and selected for performance, durability and ease of use on-site.

Suitable for a wide range of projects

PIR wall insulation is a flexible solution used in residential, commercial and light industrial buildings. It’s ideal for applications that require temperature control, fire resistance and structural reliability. They’re used in multi-unit developments and warehouses for internal partitioning, and in energy-efficient homes for thermal control.

Builders often use these panels for external cladding, fire-rated boundary walls or cool room linings where compliance and thermal performance are key. The system can be tailored to suit different project scopes and architectural needs with matching aluminium accessories and panel sizing options.

Whether you’re managing a renovation or new construction, Big Hands Building Supplies can provide what you need to get the job done right.
