PIR Foam Insulation Board: Ideal for Walls and Roofs

In modern building insulation systems, PIR Board Insulation have become a preferred choice for both exterior walls and roofing projects due to their excellent thermal performance, structural strength, and weather resistance. At GFIDuct, we provide high-performance PIR thermal insulation boards engineered to meet the rigorous demands of commercial, industrial, and steel-structure buildings.

Roof Insulation Boards Projects

PIR Board Insulation are widely used in roof insulation engineering, especially for flat roofs and steel-structure roofs. Their high thermal resistance helps minimize heat loss, while the rigid surface layer enhances structural support.

Key construction guidelines for roof insulation boards include:

Design Requirements: The thickness of the insulation layer should be calculated based on local climate and project specifications.
Panel Quality: Only certified panels with valid test reports should be used. Unqualified products are strictly prohibited.
Roof Panel Installation: For steel roofs, the boards should not be directly connected to main structural components. Instead, reliable connection systems must be used to prevent heat bridging and ensure structural safety.
Weather Conditions: Construction should not proceed in rain, snow, or winds above Force 5. Cement adhesive applications must be conducted above 5°C, and organic adhesives should not be used below -10°C.
Protective Measures: After installation, panels should be protected from mechanical damage. During subsequent works, any drilled holes or penetrations must be carefully sealed and reinsulated.

Exterior Wall Insulation Boards

In exterior wall systems, PIR foam thermal insulation boards contribute to energy-saving, moisture resistance, and thermal comfort. These panels are lightweight and offer excellent thermal insulation, making them easy to install on concrete, masonry, or steel substrates.

When used for Exterior Wall Insulation Boards, construction teams should:

Review design drawings thoroughly before starting.
Ensure even surface treatment and adhesive application for secure bonding.
Control process quality and maintain installation records for long-term performance assurance.
Best Practices and Precautions
To ensure optimal performance and durability, attention should be paid to:
Avoiding construction during adverse weather conditions.
Protecting installed insulation boards from impact or exposure.
Following proper load-transfer methods in roof systems to ensure safety and long-term stability.
