لماذا تختار لوح العزل الحراري GFI PIR؟

ألواح العزل PIR ذات أنسجة الألياف الزجاجية هي نوع من المواد العازلة المستخدمة في البناء لخصائصها الحرارية الممتازة والقوة المضافة التي توفرها طبقة أنسجة الألياف الزجاجية. إليك ما يقدمه هذا المزيج:

01 / Optimized Thickness for Modern Construction: With its 50mm thickness, this building insulation panel balances high thermal performance and installation ease. It fits easily into confined cavities in wall systems and layered roof structures, making it an optimal choice for space-efficient insulation design.

02 / Fiberglass Tissue Facing for Strength and Durability: Polyisocyanurate Foam has inherently good fire-resistant properties, making it a preferred choice for insulation in buildings where fire safety is a concern.

03 / Advanced PIR Core for Energy Savings: Unlike foil-only facings, the fiberglass tissue improves rigidity and handling durability. It resists moisture, cracking, and mechanical damage during installation, while offering excellent bonding performance for render coatings or mechanical fasteners. This makes it an ideal choice for site conditions demanding tough and reliable insulation.

04 / Moisture Resistance and Fire Safety: Made with over 90% closed-cell foam, the panel naturally repels water and retains its insulation value in humid conditions. It also meets BS 476 Part 6 & 7 Class 0 fire safety standards, limiting flame spread and reducing smoke emissions—making it suitable for use in high-compliance construction.

Typical Applications of 50mm Building Insulation Panels

• Building Wall Insulation: Serves as the thermal core in external and internal wall assemblies, suitable for render, cladding, or mechanical fixing.
• Building Roof Insulation: Ideal for flat or pitched roofs—can be applied above membranes or between rafters.
• Floor Insulation Systems: Performs well in suspended and concrete floors, enhancing both thermal performance and indoor comfort.
• Curtain Wall Systems & Cladding: Provides a non-combustible thermal barrier behind ventilated façades or glazed assemblies.

A Smarter Choice for Sustainable Construction

Choosing GFI’s Polyisocyanurate building insulation panel means less material usage to meet thermal codes—lowering transport costs, reducing jobsite waste, and supporting green building practices. These rigid insulation boards contribute to long-term sustainability goals while delivering immediate performance benefits.
