Curtain Tracks Sized to the Curtain

Start with the curtain, not the window. A curtain's weight depends on its fabric, lining, fullness and drop, and a lined, floor-length pair across a wide door can be far heavier than people expect. The profile is chosen to carry that weight across the span without bowing between brackets.

Then the gliders. They should be sized for the profile and the curtain, with one per hook plus spares at each end. Undersized gliders crack, and a missing glider leaves a gap in the heading where the fabric sags.

Brackets carry the track; their spacing decides whether it stays straight. Heavier curtains and longer drops need brackets closer together, and there must always be one near each end and either side of any bend or joint. Too few brackets is the most common cause of a sagging, sticking track.

The fixing behind each bracket matters just as much. Laterite and old masonry need resin anchors; concrete needs drilling into solid material rather than a hollow block; a false ceiling needs backing or a fix into its framing. Our ceiling curtain tracks page explains ceiling fixing in detail.

Where two curtains meet in the middle, overlap arms or master carriers let one leading edge pass in front of the other, closing the gap that otherwise lets a vertical line of light through. On blackout curtains this matters as much as the lining.

Stack-back is the width the open curtain takes up. A track extended past the window lets the curtain stack against the wall instead of the glass. The amount varies by heading and fabric; the curtain rod and track planner on this page gives a starting figure. End stops hold the curtain at the right place and stop gliders running off.

Aluminium profiles resist salt air well; plain or painted steel profiles do not, and rust along the channel is hard to stop once it starts. Nylon and acetal gliders are unaffected by humidity, but low-grade plastic gliders exposed to strong sun for years can turn brittle and snap. Keeping them behind the heading, out of direct light, prolongs their life.

The most common coastal problem is not corrosion but grit. Fine sand and salt crystals settle in the channel and make gliders drag. A dry cloth or a soft brush along the channel each season, and a dry silicone spray if needed, keeps the track running.

Most tracks are hand-drawn. Pulling at the leading edge marks pale fabric over time, so a slim draw rod clipped to the first glider is a small, sensible addition. Cord-drawn tracks move the curtain from the side, useful on wide or high windows, but in homes with children the cord loop must be tensioned to the wall.

For tall or very wide curtains, or houses that are often empty, a motorised track is the better route. It is a different system from a manual track, with its own carriers and belt; our motorised curtain tracks page covers it.
