120mm Unilin Xtroliner XO/FB Frame Insulation

120mm Unilin Xtroliner XO/FB Framing Board is engineered for versatile construction applications, including both steel and timber frame systems, with capability to reach heights of up to 11 metres.

This adaptable 120mm framing board offers flexibility in installation—it can be positioned between studs or used as an insulated sheathing board. Using 120mm XO/FB Framing Board significantly minimises Thermal Bridging, a common issue with steel or timber studs.

Specification Clause

The selected wall insulation shall be 120mm XtroLiner XO/FB, manufactured to EN 13165 standards by Unilin Insulation. This wall insulation product features a resilient modified Polyisocyanurate (PIR) core with textured, durable, low emissivity foil facings on both sides. The XtroLiner 120mm XO/FB variant has an Agrément declared Lambda value of 0.021 W/mK.

Resistance 'R' Values

To determine the resistance value for any thickness of Unilin 120mm 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).

Guidelines for Handling, Cutting, and Storage

1. Store 120mm Unilin XO/FB insulation on a clean, level surface raised above ground and protected from the elements.
2. The polythene wrapping alone does not provide adequate protection against weather exposure.
3. Take care to protect the insulation during storage and throughout the construction process.
4. Always use appropriate Personal Protective Equipment (PPE) when working with insulation materials.
