Wood, metal or aluminium curtain rail: what the difference is

Wood: a warm look with a limit on weight

A wooden rail suits older flats and wooden houses, particularly where the rest of the room has wooden windowsills, skirting or furniture. It comes in a natural finish, stained darker, or painted white, and the pole itself is usually 28 to 35 millimetres thick, which reads as more substantial than a thin metal pole even when it is not.

The trade-off is load. A wooden pole flexes and can sag over a wide window if it is asked to carry heavy blackout curtains or a lined double layer, especially when the span is longer than about two metres without a centre support. For a net curtain or a light cotton curtain it is fine for the life of the rail.

Wood does not like a damp bathroom or a kitchen directly above a hob where steam collects daily, since repeated damp cycles can warp or crack it over years. In a normal bedroom or living room, humidity is not a concern.

Metal: the strongest option, but heavier and pricier

A steel or wrought-iron rail is the one to choose for heavy curtains: thick blackout fabric, double-layer curtains with a sheer and a lined drape together, or an unusually wide window that needs a long unsupported span. Metal holds its shape under sustained weight far better than wood or aluminium.

It also comes in the widest range of finishes: brushed steel, matte black, aged brass or bronze look, which suits a more traditional or classic interior. The pole itself is heavier, which matters when it comes to fixing it to the wall, since a solid steel rail with a full curtain load needs sound wall plugs and, in a panel building, often longer anchors set into the concrete rather than just the plaster layer.

Metal is also the most expensive of the three, both as material and because a heavier rail can take a little longer to fit correctly and level. Where corrosion-resistant coating is used it copes reasonably with occasional humidity, but a plain steel finish in a genuinely wet room is not the right choice.

Aluminium: light, damp-resistant, moderate capacity

Aluminium sits between the two. It does not rust or warp with moisture, which makes it the sensible choice near a kitchen, a bathroom doorway, or a summer house with less stable heating. It is also noticeably lighter than steel, which makes it easier to fit into plasterboard partitions common in newer developments, though a plasterboard wall still needs proper cavity fixings regardless of rail weight.

Its weight capacity is decent for most everyday curtains, including a single lined curtain, but it is not the material to reach for with the heaviest blackout fabric on a wide span, where it can bow slightly over time.

Aluminium rails are usually sold with a simple brushed or white finish rather than the decorative range metal offers, so it reads as more functional than a design feature. Prices sit below steel and often close to painted wood.

Which material suits which room

The right choice depends more on the room and the curtain than on personal taste alone. A few situations come up often enough in Tallinn homes to be worth listing directly.

None of these are absolute rules, and a fixed quote from us after seeing the window and the intended curtain will confirm what a given rail can safely carry before you buy it.

• Living room with heavy lined curtains and a wide window: metal, for load and a long unsupported span
• Bedroom with a standard curtain in a wooden house or older flat: wood, for the look and adequate capacity
• Kitchen, bathroom hallway or summer house: aluminium, for damp resistance
• Panel flat with plasterboard partition walls: aluminium or a lighter wood pole, easier to fix without heavy anchors
• Wide window over 2.5 metres with any heavy fabric: metal with a centre support bracket

What we would fit in a typical Tallinn flat

For an ordinary Tallinn flat, whether a Soviet-era panel building or a newer development, we would usually recommend aluminium for a kitchen or hallway and either aluminium or a painted wood pole for a living room or bedroom with a standard curtain weight. It handles the building's humidity swings without complaint and does not need the heavier wall fixings that a full steel rail demands.

For a 1930s wooden house in Kalamaja or Nõmme with heavier drapes and higher ceilings, a metal rail earns its price, since the room usually calls for a more substantial look and the curtains are often heavier to match the taller window.

We fit curtain rails from 35 € per job, including checking the wall type and choosing the right fixings for it. If you are hanging shelves or a mirror near the same window at the same time, that is priced separately from 39 € per hour.
