Product Specifications XO Framing For Steel & Timber Xtratherm XO/FB Framing Board is designed for use with timber frame and steel frame wall constructions. XtroLiner XO range of modified PIR offers excellent insulation performance with a thermal conductivity of 0.021 W/mK and a Class ‘O’ fire rating. XtroLiner is CFC & HCFC free and is manufactured under the highest standards of ISO 9001 and 14001 Quality and Environmental Management Systems. The XtroLiner board is a modified polyisocyanurate (PIR) bonded to low emissivity textured aluminium foil facings. Class ‘O’ modified PIR insulation Steel...

Installation Guidelines Timber Framed System Glass fibre insulation or Xtratherm XtroLiner should be accurately cut to fit snugly between the timber studding. If partially filling, ensure the insulation is securely held in place by treated timber battens to provide a stop, boards can be positioned front or back of the stud. When using the XtroLiner XO/FB as a sheathing board fix the insulation outside of any breather membrane or timber sheathing on the external surface (A second breather membrane may be added at this point for further protection) and temporarily fix with large headed clout nails....

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...
