Class ‘O’ Modified PIR Insulation Cavity Wall Partial Fill Floors Solid & Suspended Systems XtroLiner XO/CW is an insulation for cavity walls where a residual cavity has to be maintained. The excellent thermal performance of the XtroLiner allows for very good U-values to be achieved whilst minimizing overall cavity wall thickness. XO/CW can be combined with Xtrathem Thermal Liner Boards to achieve U-values down to Zero Carbon fabric standards in traditional wall thicknesses. XtroLiner XO/UF under floor insulation boards are used to reduce the thermal transmittance of ground supported and suspended...
