75mm Unilin Xtroliner XO/FB Framing Board is engineered for versatile construction applications, supporting both steel and timber frame systems with wall heights up to 11 metres.
This adaptable 75mm framing board works in two ways - positioned between studs or serving as an insulated sheathing board layer. Using 75mm XO/FB Framing Board significantly reduces thermal bridging issues commonly found in steel or timber stud construction.

The specified wall insulation will be 75mm XtroLiner XO/FB, manufactured to EN 13165 standards by Unilin Insulation. This wall insulation product features a robust modified Polyisocyanurate (PIR) core with textured, durable, low emissivity foil facings on both sides. The XtroLiner XO/FB variant carries an Agrément declared Lambda value of 0.021 W/mK.
To determine the resistance value for any thickness of Unilin 75mm PIR insulation, divide the material thickness (in metres) by its Agrément declared lambda value. For example: Lambda 0.021 W/mK with 80mm thickness equals 0.080 ÷ 0.021, giving an R-Value of 3.80. Per EN 13165, R-Values must be rounded down to the nearest 0.05 (m2K/W).
