PIR-AK Board

Material: Rigid closed-cell polyisocyanurate (PIR) foam core, faced on both sides with a Kraft-aluminium multilayer complex
Declared thermal conductivity: 0.022 W/(m·K)
High compressive strength: ≥ 175 kPa for thicknesses 25-49mm; ≥ 200 kPa for thicknesses 50-160mm.
Very low water absorption: ≤ 1%
Main applications: thermal insulation in roofs with heavy protection, cold room floors.
Custom fabrication: Can be cut to pieces, with mitred edges for 90° folds, or irregular shapes

Properties and benefits

Thanks to its low conductivity, it allows for less insulation thickness for the same thermal performance, optimising space and cost.
Highly rigid and lightweight panel: facilitates handling and installation.
Multilayer facing (Kraft-aluminium), which acts as a vapour barrier and improves sealing performance.
Versatile for cutting, mitring and adaptation to complex structures (such as ducts, folds, corners)
Ideal for installations requiring high thermal performance, low thickness, and ease of installation

Typical uses

Thermal insulation of flat roofs with heavy protection build-up, such as gravel, slab or accessible traffic.
Insulation boards for cold room or cold storage floors.
Applications in industrial and commercial buildings with high thermal requirements.
Adaptation to modular systems, prefabricated or metal structures where thickness is critical.
Custom design when panels need to be adapted to irregular shapes or technical details (e.g. mitred edges for 90° folds).

Available types and sizes

Typical thicknesses: 20 / 25 / 30 / 40 mm (or others on request).
Standard and custom formats: Boards of 3000 × 1200 mm or other dimensions according to project.
Cut to size and mitred for 90° folding: Ideal for corners, rectangular ducts or other modular structures.
Additional finishes possible: profiling, perforations, grooves, machining for fixing or integration of other components.

Sustainability commitment

Fibre-free core, safer alternative for sensitive environments.
Long service life, less need for replacement and lower environmental impact.
Production on demand and cut to size, waste reduction.
