composite / Panelised / Insulated Panel
Cross-Laminated Insulated Panel (CLIP) (CLT thickness + 50mm-200mm insulation)
CLT?insulated panels use CLT with density ~500 kg/m? and thermal conductivity ~0.12 W/m?K (XLam data); overall R?value depends on added insulation.

At-a-glance signals
CLT?insulated panels use CLT with density ~500 kg/m? and thermal conductivity ~0.12 W/m?K (XLam data); overall R?value depends on added insulation.
Overview
Executive summary
CLT?insulated assemblies combine CLT structural panels with external insulation layers. XLam CLT data list mean density around 500 kg/m?, thermal conductivity about 0.12 W/m?K, and global warming potential roughly ?492 kg CO??e per m? (biogenic storage). These base CLT properties underpin CLIP assemblies; overall R?value depends on insulation thickness and type.
