What Insulation is best for use in a timber-framed construction?

The “best” insulation for timber‑frame construction depends on the balance between thermal performance, build‑up thickness, airtightness and moisture control, but, in practice, PIR insulation and insulated systems are among the most effective solutions for meeting Part L and low‑energy targets. In timber frame walls, insulation is typically installed between and/or across the studs. Options such as PIR insulation (e.g. Unilin Thin‑R Timber Frame systems) are widely used because of their low thermal conductivity (around 0.022 W/mK), meaning they can achieve the required U‑values with less thickness than mineral wool or other fibrous materials. This is particularly beneficial where wall depth is limited
