Soundproof curtain for entrance door: how to reduce noise from the landing?
The front door is the number one acoustic weak point in an apartment. Unlike windows that face the street, the door is separated from the hallway by a single leaf, often thin, with worn seals and a gap under the threshold. Every noise from the landing goes directly through it: neighbors coming home, children in the hallway, slamming doors, adjacent elevator.
An acoustic curtain installed indoors in front of the door creates a second textile barrier that absorbs these sounds before they reach your living room. No work, no authorization, no modification to the door. This guide explains how to choose the right model, how to install it correctly, and what results to expect.
Why does the front door let noise through?
A standard front door has poor acoustic insulation for three main reasons:
- Insufficient thickness: most apartment doors are 40 to 55 mm thick, well below the 70 mm needed for serious acoustic insulation.
- Worn seals: over time, the perimeter seals lose their airtightness and allow air and sound to pass through the edges.
- Gap under the threshold: the space between the bottom of the door and the floor is often 5 to 15 mm, a real sound highway for hallway noise.
The acoustic curtain intervenes on the interior side to compensate for these three weaknesses by creating an additional dense textile layer.
Acoustic curtain for front door: how many dB reduction?
Our acoustic curtains offer a sound reduction of 20 to 30 dB depending on the models and installation conditions. To give a concrete order of magnitude:
- Voices in the hallway at 60 dB reduced to a distant whisper of 30 to 40 dB perceived in your living room
- A landing door slamming at 70 dB reduced to a dull, barely perceptible sound
- An adjacent elevator rumbling attenuated below the threshold of annoyance
These results assume correct installation: the curtain must fully cover the door frame, extend 15 cm on each side, and reach the floor.
Acoustic curtain for front door: how to choose the right model?
Grammage: the number one acoustic criterion
The sound absorption of a curtain is directly related to its mass. Below 350 g/m², the attenuation is marginal. From 500 g/m², the results are significant. Our most efficient models reach 520 g/m² thanks to their multi-layer construction.
Dimensions: overlap is essential
A curtain that is too narrow lets sound pass through the sides. For a standard door of 80 to 90 cm, plan for a curtain of at least 120 cm wide (15 cm overlap on each side minimum). In height, the curtain must touch the floor to eliminate the gap under the threshold.
Flexibility: for smooth daily passage
An acoustic door curtain must be dense for insulation, but flexible so as not to hinder passage. Our models are specially designed to slide easily on the rod and be pushed aside with each opening.
Acoustic curtain for front door: our recommended models
- Gray fleece curtain -30 dB: our most acoustically efficient model, 520 g/m², maximum sound and thermal insulation
- Blackout acoustic thermal curtain sand beige: 3-in-1 solution for glazed entrances that let in light and noise
- 3-in-1 blackout thermal acoustic curtain light beige: for bright entrances that also require darkness
- Fleece thermal curtain: ideal for entrances exposed to cold in addition to acoustic insulation

Acoustic curtain for front door: how to install it correctly?
The curtain rod: ceiling, wall-mounted or telescopic?
For a front door, three mounting options depending on your situation:
- Ceiling rod: the most effective. The curtain hangs from the ceiling and fully covers the door frame. Maximizes insulation by eliminating any sound leakage above.
- Wall-mounted rod with large projection: fixed to the wall above the frame, it is suitable when the ceiling is not accessible. Plan for a projection at least 2 cm greater than the frame thickness.
- Telescopic rod: drill-free solution for tenants. It relies on tension between the two walls of the opening. Only suitable for light curtains beyond 2 kg per panel.
To learn more about drill-free solutions, consult our guide how to hang a curtain rod without drilling.
The 3 rules for effective installation
- Lateral overlap of at least 15 cm on each side of the frame to eliminate sound leaks on the edges
- Contact with the floor to eliminate the gap under the threshold, the main acoustic leak of a front door
- Frame coverage: the curtain must extend beyond the door frame on all sides, not just in width
Acoustic curtain vs. door replacement: what to choose?
Replacing a front door with an acoustic door costs between 800 and 3000 euros, requires the landlord's consent for rentals and sometimes the co-ownership trustee's. An acoustic curtain costs a fraction of that price, installs in 30 minutes, and leaves no trace.
The performance is not the same—a certified acoustic door can achieve 40 dB of attenuation compared to 20 to 30 dB for a curtain. But for the majority of daily landing noise situations, the acoustic curtain represents the best effectiveness/cost/ease ratio.

FAQ: acoustic curtain for front door
Is an acoustic front door curtain really effective against landing noise?
Yes. The front door is the main point of passage for condominium noise. A well-installed acoustic curtain reduces these nuisances by 20 to 30 dB, which transforms intrusive hallway noise into a distant, barely perceptible sound from your living room.
What curtain width for a standard front door?
For a door 80 to 90 cm wide, plan for a curtain at least 120 cm wide per panel (15 cm overlap on each side). For large entrances or double doors, two 120 cm panels are recommended.
Does the acoustic curtain hinder door opening?
No, provided you choose a flexible fabric despite its density. Our models slide easily on the rod and are pushed aside with each opening without hindering passage.
Can an acoustic front door curtain be installed without drilling?
Yes. A telescopic rod or adhesive supports allow drill-free installation. For heavy curtains (more than 2 kg per panel), a ceiling rod with toggle anchors is more suitable and leaves minimal, easily repairable marks.
What is the difference between an acoustic window curtain and a front door curtain?
These are the same products used for two different purposes. The window targets exterior noise (street, traffic), the front door targets interior condominium noise (landing, hallway, staircase). Both installations are complementary in an urban apartment exposed to both noise sources.
How long does installation take?
Approximately 30 minutes for a screwed ceiling rod. Less than 10 minutes for a telescopic rod or adhesive supports. No special skills required.
