Hide Curtain Tracks Under Cornice (Pelmet Brackets)
To conceal a curtain track, fit it behind a cornice or pelmet sized around the complete track-and-curtain assembly. Measure the track projection, carriers, fabric stack, and end clearance before choosing depth. Support the track and pelmet with fixings suited to the structure, keep services and airflow clear, and make the finished cover removable for adjustment and repair.
A neat cornice should hide the hardware, not make the curtains harder to use or maintain. The key is to plan around the track, brackets, moving carriers, and gathered fabric as one assembly. I measure and test those parts before the pelmet goes up, because a cover that looks right at rest can still catch the curtain during travel.
A pelmet is a decorative cover fitted above a window; a cornice is often a more rigid, shaped version. Both can conceal a track. The details below apply to either, whether you are adding a simple straight cover or integrating one into a larger renovation.
Planning the pelmet around the track and curtain stack
Start by measuring the actual hardware and fabric, not by choosing a standard pelmet size. The track’s wall projection sets the basic depth, but brackets, carriers, curtain folds, and end stops may need more room. There is no universal code depth or track offset that suits every window and track system.
Measure from the wall to the track’s furthest projecting part. Allow at least 25 mm (1 in) of working clearance inside the pelmet beyond that projection. Increase this allowance if carriers, stacked fabric, a lining, or decorative trim projects farther. Where space is tight, dry-fit a carrier and a sample of the curtain before fixing anything.
Check the track maker’s instructions for end clearance and end returns. These details allow the carriers to move and the end stops to work without hitting the cover. Extend the pelmet beyond the window only as far as needed to hide the track ends and curtain stack. Then confirm the curtain can draw clear of the glass and does not collide with a wall or nearby fitting.
Think of the clearance as a working envelope, not a decorative gap. A pelmet that is deep enough for the track alone may still pinch gathered fabric. Measure the curtain at its fullest stack, especially with thick fabric or a lining.
Checking access, fixing substrate, and required clearances
Before setting out the pelmet, check what is behind and around the window. The substrate is the material that will hold a fixing, such as timber framing, masonry, or a suitable wall anchor. Confirm its type and condition, then choose fixings rated by their maker for that substrate and intended use.
Survey the wall and ceiling for framing or existing backing. Also note window handles, sills, radiators, vents, and concealed services. Test the curtain’s full path against these features, not just its position when closed. Keep both fabric and pelmet clear of supply and return grilles, and follow the relevant HVAC or appliance maker’s clearance instructions. There is no universal airflow allowance for a pelmet.
If the track may need adjustment or carrier replacement, plan a serviceable cover. A removable front, accessible end, or other suitable fixing arrangement can allow access without damaging the finish. The method depends on the pelmet design and how it is supported.
Heat needs the same care. If fabric or pelmet material is near a heat-producing appliance, follow its listed clearances and local fire requirements. Do not judge a safe distance by appearance alone. If you cannot identify the appliance requirements or the wall construction, pause and get the right information before installation.
Installing brackets, track, and removable cornice
Set out the track and pelmet before drilling. Mark the track centerline, pelmet face, end returns, bracket positions, and the space needed for the curtain stack. Check measurements at both ends and across the span, since walls and ceilings may not be perfectly square or level.
Support matters as much as concealment. Fit track brackets into verified structural backing or use anchors approved for the substrate and the track maker’s stated requirements. Add backing if needed. Plaster, plasterboard, or trim alone is not reliable support unless the selected fixing system is specifically rated for that installation.
Follow the track manufacturer’s instructions for bracket locations and maximum spacing. Do not substitute a generic spacing or load figure: track design, curtain weight, fixing type, and substrate all affect the installation. Use the same care for the pelmet brackets or supports. They also need sound backing or suitable anchors.
Install the track first, then operate the curtains through their full travel. Check that carriers run freely, end stops remain in place, and the track stays aligned. Only then fit the pelmet. Keep its fixing points accessible where possible, and avoid covering an adjustment point that will be hard to reach later. Finish the surface after a second operation test.
Testing operation, support, and final safety clearances
A finished pelmet can hide a problem as easily as it hides a track. Test the whole assembly before calling the work complete: open and close the curtains fully, inspect the ends, and check that fabric does not snag or press against the cover. Look for track movement or deflection while the curtains operate.
| Check | What to verify | If it fails |
|---|---|---|
| Curtain travel | Fabric clears the pelmet, sill, handles, and nearby finishes | Recheck depth, end allowance, and stack space |
| Track support | Brackets stay secure and the track remains aligned | Stop using it; check backing, anchors, and maker instructions |
| End operation | Carriers and end stops move without striking the cover | Adjust end clearance or pelmet position |
| Ventilation and heat | Grilles remain open; required appliance clearances are met | Alter the cover or seek the relevant product guidance |
| Future access | Track adjustments and carrier replacement remain possible | Add a removable or serviceable access method |
A fixing that feels tight is not automatically a sound fixing. A wall plug in unsupported plasterboard, or a screw into trim, does not become structural support through a snug fit. If the track binds or shifts, do not hide the issue behind the pelmet. Recheck the substrate, anchor type, spacing, and the manufacturer’s allowable load information.
Common installation situations and what they reveal
The examples below describe recurring site conditions, not universal dimensions or product specifications. I use them to show how the same design checks guide different projects. In each case, the right clearance and fixing depend on the actual track, curtain, wall, and surrounding features.
A lined curtain with a deep stack: The track fits behind the planned cover, but the gathered fabric crowds the inside face when drawn open. The useful check is the full stack depth, including lining, rather than the track projection alone. A deeper pelmet or adjusted side coverage may be needed, provided the curtain still draws clear.
A shallow window reveal with a handle nearby: A slim cover appears to fit, yet the curtain catches the handle during travel. Test the path with the handle in its normal position and consider the track offset and pelmet depth together. Do not solve the collision by narrowing the curtain’s usable travel unless that compromise is intended.
A pelmet fixed to decorative trim: The cover looks secure at first, but the trim is not verified as structural backing. The correct response is to identify the substrate and select support suited to it, or add backing where needed. Concealment does not reduce the load on the fixings.
A window beside a vent or heater: The cover would overlap a grille or sit close to a heat source. Check the equipment instructions and local requirements before deciding on the shape or location. A clean visual line is not a reason to block airflow or guess at a safe heat clearance.
Conclusion and FAQ
A successful cornice conceals the track while leaving room for carriers, fabric, and service access. Measure the full assembly, use the track and fixing makers’ limits, verify the support, and test the curtains before and after fitting the cover. These checks help protect both the finish and everyday operation.
How deep should a pelmet be to hide a curtain track?
Measure the track’s furthest wall projection and allow at least 25 mm (1 in) of working clearance beyond it. Add room for projecting carriers, gathered fabric, lining, or trim as needed.
How far should the pelmet extend past the window?
Extend it only enough to conceal the track ends and curtain stack. Check the track maker’s end requirements and confirm the curtain can draw clear of the window.
Can I fix a pelmet bracket to plasterboard?
Only use a fixing system specifically rated for that substrate and installation. Otherwise, locate structural backing or add suitable support. Do not treat a tight-feeling plug as proof of adequate support.
How far apart should curtain-track brackets be?
Use the track manufacturer’s maximum spacing and end-support instructions. There is no universal spacing that applies to every track, curtain, and fixing substrate.
Should I install the track or pelmet first?
Set out both, then install and test the track before enclosing it with the pelmet. This lets you check alignment, carrier movement, end stops, and curtain clearance while everything is accessible.
How much end clearance does a curtain track need?
Use the end clearance or return specified for that track system. It must let the carriers and end stops operate without striking the pelmet.
Can a pelmet cover a vent or grille?
Do not block supply or return grilles. Keep the cover and fabric clear, and follow the HVAC or appliance manufacturer’s instructions for required clearances.
How do I keep the track accessible after fitting the pelmet?
Choose a removable or serviceable fixing arrangement if future adjustment or carrier replacement would otherwise require destructive removal. Plan access before finishing the cover.
What should I do if the curtain binds after installation?
Stop and check for contact with the pelmet, wall, handle, or other fittings. Also inspect track alignment, bracket security, and end clearance before using the curtains again.
Is there a standard code-required pelmet depth?
No universal depth, track offset, bracket spacing, or track load rating applies to every installation. Follow the product instructions and applicable local building and fire requirements.
