Wooden Wall Panels, Specified for Goa

Termites are the first conversation about wood in Goa. They travel through the ground, up inside walls and along hidden voids, and a timber panel fixed against a plaster wall is exactly the dark, undisturbed place they prefer. The damage is usually invisible until the panel sounds hollow or crumbles.

Protection is layered. The timber is chosen for natural durability or treated with a preservative. The wall is inspected for existing mud tubes and treated if there is any sign of activity. The battens are treated timber or a composite that termites ignore, and the panel stops short of the floor so a gap can be inspected. In houses with a history of termites, a pre-construction or post-construction treatment by a pest specialist is worth doing before any panelling goes up.

Laterite blocks are porous, and a wall that faces the monsoon rain or sits on damp ground can hold moisture for months. Before we panel a wall we take moisture readings at several heights and look for tide marks, peeling paint and white salt deposits. If the wall is wet, the cause comes first: an external crack, a missing drip, a blocked gutter or damp rising from below.

Wooden panelling is always fixed on battens, never glued flat to the plaster. The battens hold the panel off the wall and create a ventilation gap, usually open at the top and bottom, so air can move behind the timber and carry moisture away. A breathable membrane can go on the wall in borderline cases. The gap is what stops the back of the panel from sitting against cool, damp masonry and growing mould unseen.

Timber delivered from a dry store and fixed straight away in a humid room will swell after it goes up. Boards and sheets should sit in the room, stacked with spacers so air reaches them, for some days before fitting, so they settle to the moisture level they will live at. In the monsoon this matters even more.

Sealing is the second half. A board finished only on its visible face takes up moisture through its back and edges and cups. Every face, including the back and every cut edge, should get at least a sealing coat. Cut edges made on site around switches and corners are the usual weak point and need sealing before the panel is fixed.

In an older house with high ceilings and tall windows, timber panelling to dado or door height echoes the shutters and the beams. A darker stain with a soft oiled finish looks settled; a glossy lacquer can look out of period. Lime-washed walls above timber below is a combination that suits these rooms.

In a newer flat or villa, timber is often used as a single slatted wall or a band behind the bed, with a matt, natural finish. Pale woods keep a small room light; darker woods make a large room feel more intimate. Wherever it goes, the grain direction and the finish should be consistent with the doors and furniture nearby.

Near the sea, salt-laden air dulls oil finishes faster and corrodes ordinary steel screws and nails, which then stain the timber black around each fixing. We use stainless or coated fixings. Strong afternoon sun through a west window bleaches and dries timber; a UV-protective finish or a blind on that window slows it down.

A house closed for weeks through the monsoon is the hardest test. Without air movement, humidity stays high and the surface of the timber can grow a grey bloom. A dehumidifier on a timer, a caretaker opening windows on dry days, or simply wiping the panels down before you leave all reduce the risk considerably.
