Experts in Insulated Panels

Why PIR?

PIR (Polyisocyanurate) is a closed cell rigid polyurethane foam made by mixing two main chemical streams (isocyanate and polyol) with appropriate catalysts and a blowing agent. The mixture undergoes a number of processes including foaming and expansion, heating, curing, trimming and cutting followed by quality control to produce the panel as you know it. These processes produce a cross-linked and closed cell structure, which contributes to the rigidity, stability, compressive strength and insulation properties of the panel, by reducing heat transfer through convection.


PIR has superb thermal performance and allows buildings to achieve premium levels of energy efficiency, with some of the thinnest available solutions. It does not sag or absorb moisture so you can be confident of consistent performance which will last the lifetime of the building. Due to its closed cell structure, PIR is a hydrophobic product meaning it does not absorb water. This allows thermal performance to be retained regardless of water exposure. PIR is a thermoset material which does not melt, flow or drip when exposed to fire. It will form a strong char that helps protect the foam core and prevent flame spread.


Our current range of PIR products include:

Insulated Panels

Insulated Wall Panels
