How to Install Curtains for Velux Windows: Complete Guide
Your skylight floods the room with generous light, yet without control, that brightness can quickly become intrusive. Fitting curtains for a Velux window is far more than a decorative gesture: it is a strategic choice for thermal comfort, privacy, and restful sleep. From integrated systems and bespoke tracks to blackout fabrics that soften the sun’s glare, this subject deserves your careful consideration. This guide sheds light on the available solutions and essential criteria to turn your sloping window into a true asset, balancing luminosity with serenity in your everyday living space.
Installing curtains for Velux windows is much more than just a decorative choice. It is an essential practical and aesthetic solution for controlling light, regulating temperature, and preserving privacy in these sun-drenched rooms. Whether you have a loft, a bedroom under the eaves, or a bathroom with a skylight, choosing and installing the right shading system requires special attention. This article guides you step by step, from crucial selection criteria to installation techniques, including current trends in fabrics and designs, to transform your Velux into a comfortable and stylish asset.
Why install curtains on a Velux roof window?
Roof windows bring incomparable brightness and a sense of space. However, without control, this light can become a drawback. Curtains specially designed for Velux meet specific needs that go beyond mere aesthetics. Their primary function is natural light management. They help soften the sun's rays during the most intense hours, protecting both your eyes and your furniture from UV damage.
Secondly, they play a major role in thermal and acoustic insulation. Even a high-performance roof window can be a point of heat loss in winter and overheating in summer. A curtain with a suitable lining creates an additional insulating air layer. Similarly, it can muffle the sound of rain or hail, providing significant comfort.
Finally, they guarantee privacy and total darkness for bedrooms. Waking up with the rising sun is pleasant, but being able to sleep in complete darkness is equally so. An effective shading system is therefore essential for restful sleep.
The different types of shading systems for Velux
Before choosing your curtains, it is essential to understand the available mounting systems. They are not installed in the same way as on a standard window.
Specific Velux blinds and roller shutters
Velux offers its own range of integrated blinds, such as manual or electric roller blinds, roller shutters, or pleated blinds. They are designed to fit perfectly into the window frame, offering a professional finish and optimal sealing. Installation is typically done on the window frame itself. This is a high-end solution, often more expensive, but extremely effective and durable.
Rail kits for classic curtains
For those who prefer the aesthetic and warmth of a fabric curtain, specific rail kits are available. They are fixed either to the ceiling (following its slope) or to the side jambs of the Velux. These kits allow the use of almost any fabric, offering total decorative freedom. They often consist of a curved rail or tracks that follow the slope of the window.
Custom and alternative solutions
For more complex installations or a unique design, custom-made is the solution. Specialized companies create curtains and rail systems adapted to the exact dimensions and slope of your Velux. Additionally, alternative solutions such as adhesive solar films (to reduce heat and UV) or magnetic blackout covers (for total darkness) can complement or replace curtains.
How to choose your Velux curtains wisely: essential criteria
Choosing the perfect curtain depends on a combination of technical and aesthetic factors. Do not overlook any of these points for a result that meets your expectations.
Taking measurements: a crucial step
This is the foundation of any successful installation. Always measure the internal opening of the window (the width and height between the frames) and not the glass. Note the roof pitch angle, as it will influence the choice of rail system. Also determine whether you want the curtain to strictly cover the window or extend beyond the sides for better blackout.
Choosing the fabric and material
The material determines functionality. For a bedroom, opt for opaque and thick fabrics (velvet, blackout canvas) for darkness. In a home office or living room, lighter, translucent fabrics (linen, voile) diffuse soft light. Also consider thermal fabrics and insulating linings to improve energy efficiency. Current trends favor natural and textured materials like raw linen or thick cotton.
Color and design: decorative integration
A Velux curtain can be a discreet element or a centerpiece. To visually enlarge the space and reflect light, light and neutral tones (white, ecru, light grey) are unbeatable. Geometric patterns or vertical stripes can add dynamism. The idea is to harmonize the curtain with the rest of your decor, whether it's your bedding, sofa, or wall color.
Opening and closing system
How will you operate your curtain daily? A manual system with a rod or cord is simple. But for a high or hard-to-reach window, a motorized system, controllable by remote or even via a smartphone app, is a game-changer. This is a comfort investment, particularly appreciated in smart homes.
Step-by-step installation guide for a Velux curtain rail kit
Installing a universal kit is within the reach of many DIY enthusiasts. Here is a general method. Always consult the specific instructions for your kit.
Step 1: Preparation and marking. Gather all materials: the rail kit, a tape measure, a spirit level (or laser level for slopes), a pencil, a drill/driver, wall plugs and screws suitable for your support (drywall, wood, concrete). Clean the mounting area thoroughly. Position the rail or brackets following the roof slope and mark the locations for the fixing holes.
Step 2: Fixing the rail or brackets. Drill at the marked locations with a suitable drill bit. Insert wall plugs if necessary. Screw the brackets or the complete rail firmly, ensuring it is perfectly aligned and stable. A sagging rail will compromise the smooth glide of the curtain.
Step 3: Hanging the curtain. Attach the curtain hooks or gliders to the rail. For curtains with eyelets or rings, simply thread them onto the rod. Slide the assembly to check the smoothness of movement. Adjust the curtain length if needed (iron-on or sewn hem).
Step 4: Finishing and adjustments. Check that the curtain covers the entire window surface when closed and does not obstruct the opening of the Velux window. Adjust the tension of cords or mechanisms if your kit is equipped with them. Clean any fingerprints or dust.
Mistakes to absolutely avoid during installation
Some common mistakes can ruin the final result or even damage your window. Here are the main ones.
Neglecting the strength of the support. Fixing a rail to a simple plasterboard partition without reinforcement is a guarantee of failure. Always use suitable wall plugs (Molly, butterfly) or fix into the roof structure if accessible.
Incorrectly calculating measurements. A curtain that is too short lets in annoying side strips of light. A curtain that is too wide can bunch against the walls and slide poorly. Measure three times, cut once!
Choosing an unsuitable fabric. A very fine voile in a bedroom will never provide the desired darkness. Conversely, a thick velvet in a small space can visually weigh it down.
Forgetting about maintenance. Dust and pollutants accumulate quickly on roof windows. Choose washable fabrics or plan regular cleaning to preserve the beauty and hygiene of your curtains.
Deco trends 2026: dressing your Velux windows with style
Velux curtains are no longer limited to simple white blinds. They are becoming true design elements.
The trend is towards natural materials and textures. Linen, in all its forms, is king. It brings an organic, slightly wrinkled, very soothing touch. Linen-cotton blends or light jute canvases are also popular for their raw and authentic look.
In terms of colors, we are seeing a return of earthy and deep tones. Sage green, terracotta, teal, or even mustard add a warm and contemporary touch, often contrasting with light walls. Black, used sparingly on a single Velux, creates a graphic and sophisticated effect.
Finally, smart custom-made solutions are becoming more common. This involves creating curtains that are an integral part of the architecture, with shapes that follow complex attic spaces or systems of layered sheers (a translucent voile + an opaque curtain) for ultra-precise light modulation.
Budget: how much does it cost to install Velux curtains?
The budget can vary considerably depending on the chosen solution.
A simple universal rail kit, to be installed yourself, costs between €30 and €100. You need to add the cost of the fabric and any sewing.
Velux brand blinds and roller shutters (supply and installation by a professional) represent a larger investment, typically between €200 and €600 per window, depending on the model and motorization.
The custom haute couture solution, with a complex rail system and designer fabric, can easily exceed €800 to €1000 per window. This is the price of exclusivity and perfect integration.
Don't forget to consider possible financial aid. Some high-performance shading solutions, as part of a comprehensive energy renovation, may be eligible for grants like MaPrimeRénov'. Check with the relevant organizations.
FAQ: Your questions about Velux curtains
Can you install regular curtains on a Velux?
Yes, but not directly. You cannot simply hang a straight rod above an inclined Velux. It is imperative to use a specific rail kit designed to follow the roof slope. This kit will serve as a support for your "regular" curtains. Ensure the chosen fabric is not too heavy for the system.
How to achieve total darkness with a Velux?
Total darkness requires a combination of factors. First, choose a quality "blackout" fabric with an integrated opaque lining. Then, opt for a mounting system (rail or blind) that allows the curtain to press tightly against the frame all around, without light gaps on the sides. Velux integrated blinds with side guides are often the most effective for this.
What is the best alternative to curtains for a Velux?
Several alternatives exist depending on the need. Adhesive solar films are excellent for reducing heat and UV without obstructing the view. External blinds (sunshades) are very effective at blocking heat before it enters. Finally, removable blackout covers made of foam or aluminum, often fixed magnetically, offer the best thermal and acoustic insulation for the night.
How to maintain and clean your Velux curtains?
Maintenance depends on the fabric. For most modern fabrics, regular vacuuming with a soft brush is sufficient. Check the label for washing: some are machine washable at low temperature, others require dry cleaning. For fabric blinds from integrated kits, a slightly damp microfiber cloth is generally recommended. Avoid abrasive products.
Is it possible to motorize a Velux curtain after installation?
Absolutely. Many systems, whether integrated blinds or curtain rails, offer retrofit motorization kits. They often involve replacing the manual mechanism with a discreet motor, powered by mains or battery. This is an excellent solution to improve comfort without changing everything, especially for high or multiple windows.
Conclusion: Creating harmony between light and comfort
Installing curtains for Velux is a project that perfectly combines technique and creativity. By understanding the different systems, choosing materials suited to your needs (light, heat, privacy), and following a careful installation, you transform a simple roof window into a true element of comfort and decoration. Whether you opt for the clean simplicity of an integrated blind or the warm character of a linen curtain on a curved rail, the result should bring you serenity and daily pleasure.
