High-Performance Rigid Foam 50mm PIR Insulation Board

En Fiberglass PIR Insulation Boards 50mm is a premium rigid insulation board made with a high-density polyisocyanurate (PIR) foam core and fiberglass tissue facings on both sides. Designed for enhanced thermal efficiency and durability, this 50mm insulation panel is ideal for building wall insulation, building roof insulation, and floor systems—making it suitable for both new constructions and renovation projects.

Why 50mm Polyisocyanurate Panels Stand Out

En PIR Insulation Boards 50mm is a widely adopted standard in modern building insulation.

Its popularity comes from its ability to deliver outstanding thermal performance in a compact and lightweight form.

With a low thermal conductivity of less than 0.024 W/m·K, this rigid insulation board provides exceptional energy efficiency while saving valuable installation space.

It is a go-to solution for architects and builders prioritizing thermal performance and structural reliability in both building roof insulation and building wall insulation projects.

¿Por qué elegir el panel de aislamiento térmico GFI PIR?

Las planchas aislantes PIR con tejido de fibra de vidrio son un tipo de material aislante utilizado en la construcción por sus excelentes propiedades térmicas y la resistencia añadida que proporciona la capa de tejido de fibra de vidrio. Esto es lo que ofrece esta combinación:

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.

Prueba de comparación

Las siguientes imágenes muestran el estado del tablero compuesto ignífugo de aislamiento de poliisocianurato RLB-l bajo la combustión directa del soplete de llama de 1300℃ durante cada período de tiempo. Durante todo el experimento, la placa aislante de poliisocianurato RLB-I no se quemó y no goteó agua. Al evitar la propagación de la llama y la conducción del calor, no se produjo ningún fenómeno de combustión.
