What material should be used to panel walls in a wooden house to prevent mice? - briefly
Install a continuous metal barrier—such as 0.5 mm steel or aluminum sheathing—directly over the studs. This eliminates gaps that mice can exploit and provides a durable, non‑chewable surface.

A solid, non‑porous barrier is essential for rodent resistance. The most effective options are:
- Metal sheathing (galvanized steel or aluminum). Rigid, impervious to gnawing, can be fastened directly to studs. Use sheets at least 0.5 mm thick; seal seams with stainless‑steel screws and a silicone‑based sealant.
- Concrete panels (pre‑cast or poured in place). Provide a hard, continuous surface that mice cannot chew through. Apply a vapor‑barrier membrane on the interior side to prevent moisture migration.
- Fiber‑reinforced polymer (FRP) boards. Combine high tensile strength with a smooth finish. Install with epoxy‑bonded anchors; joint tape and polyurethane sealant close any gaps.
- Hardboard with metal mesh backing. The outer layer resists moisture, while the embedded mesh blocks rodent entry. Secure with corrosion‑resistant nails; tape seams with metal‑foil tape.
Additional measures:
- Seal all penetrations – pipe sleeves, electrical boxes, and vent openings must be wrapped in copper mesh (minimum 1 mm wire gauge) and sealed with expanding foam that hardens.
- Install a continuous perimeter strip – a metal flashing or rubberized barrier at the base of the wall prevents mice from entering from the foundation.
- Use rodent‑grade fasteners – stainless‑steel or hardened steel screws with a minimum head diameter of 6 mm reduce the risk of stripping.
- Apply a deterrent coating – a thin layer of lanolin‑based repellent on the interior surface can discourage chewing without affecting material integrity.
Choosing a material that combines hardness, durability, and seamless installation will markedly reduce the likelihood of mouse intrusion in a timber‑frame residence.
