PIR-ALU Board

Material: Rigid polyisocyanurate (PIR) foam core, fiber-free, coated on both sides with embossed aluminum foil.
Declared thermal conductivity: 0.023 W/(m·K)
Water absorption: ≤ 1%
Reaction to fire: C-s2, d0
Surface finish: Aluminum foil on both sides, also acting as a barrier.
Custom manufacturing: Can be cut into pieces, mitered for 90° folds, adapting to duct or installation tunnel formats.

Properties and benefits

High rigidity and low weight: Lightweight panels with great structural resistance.
Low water absorption: Thanks to the closed-cell core and aluminum coating.
High dimensional stability: Good performance against thermal changes and humidity.
Efficient thermal insulation: Ideal for HVAC ducts, air conditioning, and technical rooms.
Easy cutting, assembly, and machining: Perfect for adapting to technical enclosures or modular construction.
Professional aluminum finish: Ideal for visible applications or where cleanliness/aesthetics matter (cleanrooms, hospitals).

Typical uses

Thermal insulation for ventilation ducts, air conditioning (HVAC), and air distribution.
Installations in environments such as hospitals, cleanrooms, food industry, or data centers, where fiber-free panels are required.
Manufacturing of pre-insulated panels, duct boxes, or air conditioning modules.
Applications in commercial, tertiary, industrial buildings, or technical installations.

Available types and sizes

Typical thicknesses: 20 / 25 / 30 / 40 mm (or others upon request).
Standard and custom formats: 3000 × 1200 mm boards or other dimensions as per project.
Custom cutting and miter for 90° fold: Ideal for corners, rectangular ducts, or other modular structures.
Embossed aluminum finish and integrated vapor barrier.
Additional finishes possible: profiling, perforations, grooves, machining for fastening or integration of other components.
