PIR Insulation Boards: A Practical Guide – Selection, Installation, and Common Pitfalls
Anyone working in construction knows this truth: when insulation fails, it's rarely because the board itself was defective. More often, it's because someone chose the wrong specification or installed a critical detail incorrectly. PIR (polyisocyanurate) insulation boards have become increasingly popular in recent years, and the performance data is genuinely impressive – thermal conductivity as low as 0.022 W/(m·K), better fire performance than standard polyurethane, and far superior dimensional stability compared to EPS and XPS.
