How to hang a curtain without drilling: 5 tested and compared solutions
To hang curtains without drilling, there are 5 solutions: the tension rod (3 to 8 kg), magnetic supports (5 to 12 kg), roller shutter box supports (3 to 6 kg), adhesive hooks (2 to 4 kg), and adhesive rods (1 to 3 kg). Only tension rods and magnetic supports are suitable for heavy technical curtains weighing over 600 g/m².
The choice depends on the weight of your curtain, the material of your window frame, and the size of the opening. This guide compares the 5 solutions with their actual load capacities, limitations, and durability, to help you choose the right attachment for your situation.
The tension rod: 3 to 8 kg capacity
The tension rod is an extendable metal bar held by pressure between two parallel surfaces (walls or window frame). It supports 3 to 8 kg depending on the diameter and model, making it one of the most versatile no-drill solutions. Installation takes 2 minutes, no tools required, and the rubber end caps leave no marks on the walls.
For sheer curtains and light decorative curtains, the tension rod works on all window sizes. For high-density technical curtains (620 g/m² like Kurtens curtains), limitations appear quickly. A 250x230 cm curtain at 620 g/m² weighs approximately 3.6 kg: the rod holds, but with little safety margin. At 300x270 cm, the weight exceeds 5 kg, which creates a risk of falling for most telescopic models.
Verdict: reliable solution for small windows (100x150 or 150x230 cm) with light to medium curtains. For large windows with technical curtains, prefer classic wall mounting.
Adhesive hooks: 2 to 4 kg, reserved for sheer curtains
Adhesive hooks support 2 to 4 kg under normal conditions, which limits them to sheer and light curtains. They attach via double-sided tape to walls or window frames, with no tools and no visible marks upon removal (if the adhesive is of good quality).
"High capacity" models advertise up to 9 kg, but these figures are measured in a laboratory on smooth, clean surfaces. In real conditions, adhesion degrades with heat (south exposure in summer), humidity (bathroom, kitchen), and time. According to adhesive strength tests published by the French National Metrology and Testing Laboratory (LNE), the load capacity of adhesive fixings decreases by 30 to 50% after 6 months of exposure to temperature variations.
For multi-layer technical curtains over 600 g/m², the risk is real: the curtain can fall in the middle of the night, taking the rod and potentially the wall plaster with it. Reserve adhesive hooks for sheer curtains, light decorative curtains, and small windows.
Magnetic supports: 5 to 12 kg, the best no-drill option for heavy curtains
Neodymium magnetic supports support 5 to 12 kg depending on the magnet's strength, making them the strongest no-drill solution on the market. They adhere to ferrous surfaces: steel window frames, metal veranda structures, and wrought iron supports. The attachment is 100% reversible, without any marks.
This is one of the few no-drill solutions genuinely compatible with heavy technical curtains. A 250x230 cm Kurtens curtain at 620 g/m² (approximately 3.6 kg) remains well within the limits of a quality magnetic support. Even at 300x270 cm (approximately 5 kg), the safety margin remains comfortable with neodymium magnets with an 8 to 12 kg capacity.
Simple test: bring a refrigerator magnet close to your window frame. If it sticks, magnetic supports will work. If it doesn't stick, your frame is made of PVC, aluminum, or wood, and magnetic supports are incompatible. PVC represents the majority of windows in recent construction in France, which limits this solution to older windows with metal frames or verandas.
Indicative price: 15 to 40 euros per pair depending on power.
Roller shutter box supports: 3 to 6 kg depending on the system
Roller shutter box supports utilize the box located above the window to attach a curtain rod without drilling. Three variants exist, with different load capacities:
- Side pressure supports: two pieces clamp against the internal walls of the box. Capacity: 5 to 6 kg. The strongest solution in this category.
- Hook-clip systems: hooks engage in the grooves of the box. Capacity: 3 to 5 kg. Compatibility varies depending on roller shutter brands (Somfy, Bubendorff, ACGM).
- Adhesive rods for casing: attached by adhesive to the front of the box. Capacity: 1 to 3 kg. Same limitations as classic adhesive hooks.
This solution is suitable for light to medium curtains on windows equipped with an exposed interior roller shutter box. The result is discreet: once installed, the supports are almost invisible. The main limitation is compatibility: not all boxes are compatible, and recessed wall boxes do not allow for this type of attachment.
Indicative price: 10 to 30 euros per kit.
Adhesive rod: 1 to 3 kg, only for thin curtains
The adhesive rod is a lightweight rod fixed directly to the wall or ceiling by an integrated adhesive. It supports 1 to 3 kg, making it the no-drill solution with the lowest load capacity. The aesthetic is pleasing and discreet, but its long-term reliability remains limited.
Reserve this solution exclusively for sheer curtains and very light decorative curtains. For any curtain with a technical function (blackout, thermal, acoustic), the adhesive rod is inadequate: the weight of a multi-layer curtain systematically exceeds its capacity.
Indicative price: 8 to 20 euros.
Summary: which solution for the weight of your curtain
The table below compares the 5 no-drill solutions according to their load capacity, compatibility with different types of curtains, average price, and long-term durability.
| Solution | Weight supported | Sheer / light curtain | Heavy technical curtain (620 g/m²) | Average price | Durability |
|---|---|---|---|---|---|
| Tension rod | 3 to 8 kg | YES | Small windows only | 10 to 35 euros | Excellent (mechanical) |
| Magnetic supports | 5 to 12 kg | YES | YES (if metal frame) | 15 to 40 euros | Excellent (mechanical) |
| Roller shutter box supports | 3 to 6 kg | YES | Depending on model | 10 to 30 euros | Good (mechanical) |
| Adhesive hooks | 2 to 4 kg | YES | NO | 5 to 15 euros | Medium (degradation 6-12 months) |
| Adhesive rod | 1 to 3 kg | YES | NO | 8 to 20 euros | Low (degradation 3-6 months) |
Reading the table: mechanical solutions (tension rods, magnetic supports, box supports) retain their load capacity over time. Adhesive solutions (hooks, adhesive rods) lose 30 to 50% of their adhesion in 6 to 12 months depending on conditions (heat, humidity).
When drilling remains the best option
The classic wall mounting (2 screws per side) supports 15 to 20 kg, which is 3 to 4 times more than any no-drill solution. For high-density technical curtains, drilling remains the only reliable attachment for large windows and bay windows.
Kurtens custom-made curtains weigh 620 g/m²*. This high density is what allows them to offer up to 7 °C of thermal gain*, 100% blackout*, and 22 dB of sound attenuation*. This weight requires appropriate attachment. A classic wall rod with two screwed side supports handles 15 to 20 kg effortlessly, leaving a safety margin of 3 to 4 times the actual weight of the curtain.
Installation takes 10 minutes with a drill: 2 holes per side, 4 anchors, 4 screws. For tenants, the 2 small screw holes can be filled in 30 seconds with a 3-euro tube of spackling compound, during the exit inventory. This simple gesture is more reliable than risking a curtain falling in the middle of the night with a no-drill solution unsuited to the weight.
Kurtens custom-made curtains are available with grommets, pleating tape, or rod pockets, compatible with any standard wall rod. Advantage of custom-made for tenants: curtains unhook in 30 seconds, the rod unscrews in 2 minutes, and everything goes with you when you move. It's the only truly portable insulation solution: thermal, blackout, and acoustic performance that accompanies you from one home to another.
To choose the right attachment for your configuration, consult the complete Kurtens attachment guide. If you are installing a thermal curtain, also check which way to position it to maximize insulation. And to determine the exact dimensions of your curtain, the size guide will help you step-by-step.

Frequently Asked Questions
Which no-drill rod for a heavy curtain?
Heavy curtains (600 g/m² and more, multi-layer technical curtain type) quickly exceed the limits of no-drill solutions. The tension rod is suitable for small windows (maximum 150x230 cm) with a capacity of 3 to 8 kg. Magnetic supports (5 to 12 kg) work on metal frames. Beyond these cases, classic wall mounting (2 screws per side, 15 to 20 kg capacity) remains the safest and most durable solution.
Do adhesive hooks hold for a blackout curtain?
For a light single-layer blackout curtain, high-capacity adhesive hooks (advertised 9 kg) may be suitable in the short term. For a high-density multi-layer blackout curtain (620 g/m² like Kurtens curtains), adhesive hooks are insufficient. The weight exceeds the adhesive's actual capacity, especially after a few months of use. Heat and humidity accelerate the degradation of adhesion. Concrete risk: the curtain and rod fall in the middle of the night.
How to hang a curtain without drilling on a PVC window?
PVC windows are compatible with the tension rod, which is held by pressure between the frame walls without damaging it. Magnetic supports do not work on PVC (non-ferrous material). Specialized clips for PVC frames also exist, attaching to the edge of the frame without drilling or adhesive. For heavy curtains on large PVC windows, wall mounting (in the wall, not in the PVC frame) remains the most reliable solution.
Can a custom-made thermal curtain be installed without drilling?
Yes, on small windows (100x150 or 150x230 cm) with a solid tension rod (6 to 8 kg capacity). For large windows or bay windows, classic wall mounting is recommended for high-density thermal curtains. Kurtens thermal curtains weigh 620 g/m²* to offer up to 7 °C of thermal gain*: this density guarantees performance but implies a heavier weight than a standard curtain. Two screws per side are sufficient, and the rod is easily removed when moving.
Does hanging a curtain without drilling damage the wall when removed?
Tension rods leave no marks: they are held by pressure with rubber end caps. Quality adhesives (3M Command or Tesa brands) remove cleanly from smooth surfaces. Only low-end adhesives risk leaving residue or tearing off plaster. Note: even classic wall mounting (2 small screw holes) can be filled in 30 seconds with a 3-euro tube of spackling compound. This repair is often simpler and more reliable than looking for a no-drill solution unsuited to the curtain's weight.
What is the most durable no-drill solution over time?
Mechanical solutions (tension rods and magnetic supports) retain their load capacity indefinitely because they do not rely on adhesive. Adhesive solutions (hooks and adhesive rods) lose 30 to 50% of their adhesion in 6 to 12 months, depending on exposure to heat and humidity. For a durable no-drill installation, opt for a quality tension rod (minimum 25 mm diameter) or neodymium magnetic supports if your frame is metal.
How do you hang a curtain without drilling or a rod?
Without a rod, there are two options: wall-mounted adhesive hooks that hold the curtain's eyelets or clips directly (for sheers only, 2 to 4 kg), or a cable tensioned between two pressure supports for a very light curtain. For a heavy technical curtain, these methods are not enough: a rod is still needed, fixed with magnetic supports or to the wall.
How do you fix a curtain to the ceiling without drilling?
On a ceiling, no-drill solutions are limited because there is no side support. Adhesive ceiling rods hold 1 to 3 kg, enough for a sheer only. For a blackout or thermal curtain on the ceiling, drilling with anchors suited to the material (plasterboard or concrete) remains the only reliable fixing.
