At Your Doorstep
Silence the Room Without Losing Your View.
The Soundproof Curtain PRO KK1455 blocks noise and cold air — but it also blocks your view. If you need to monitor a workshop floor, see a performer from the control room, keep an eye on the hallway, or just let light through while keeping drafts out, the solid curtain isn't the right tool.
The Soundproof Curtain PRO with Window is. Same three-layer high-density cotton construction as the Soundproof Curtain PRO — same sound dampening, same thermal insulation, same no-tool hanging installation. But with a built-in double-glazed shatter-resistant glass window that lets you see through without breaking the acoustic and thermal seal.
One curtain. Blocks noise. Blocks cold. Keeps you connected to what's on the other side.

|---|---|
| Window | Double-glazed shatter-resistant glass panel, set into the curtain body with an insulated surround frame |
| Sound performance | Dampens and absorbs — reduces noise passing through door gaps and adds mass to the door assembly. Not a rated STC product. Acoustic curtains reduce and dampen noise — they do not eliminate it. |
| Thermal performance | Multi-layer cotton fill + double-glazed window insulates against cold drafts, heat loss, and temperature swings |
| Waterproof | Yes — outer fabric layer is waterproof |

What's in the box
- 1 × Soundproof Curtain PRO with Window — KK1456 (your size and color)
- Quick-start install guide with size, hanging, and window-care recommendations
Install in 3 steps
- Choose your hanging method. Use a curtain rod mounted above the door frame, heavy-duty over-door hooks, or a ceiling-mounted track. Position the rod so the window lands at a comfortable eye level for your use case — typically mid-curtain height works for most standing-height sightlines.
- Hang and let it settle. Slide the curtain onto the rod or hooks. The weight of the fill layers and the glass panel will pull it straight within a few hours. Do not force-fold or compress the window area during storage or installation.
- Check coverage and sightline. Close the curtain, check all edges overlap the frame, then confirm the window is positioned where you need it. Adjust the rod height if the sightline needs to move.
Made for
- Recording studios where the engineer needs to see the performer without losing acoustic treatment
- Workshops and garages where you need to monitor the other side without opening the door
- Warehouses and factories where supervisors need visibility into production areas
- Home offices where you want to see if someone's approaching without breaking the sound barrier
- Nurseries where parents want to check on sleeping children without opening the door
- Renters who can't make permanent changes — no drilling, no adhesive, no door damage

FAQ
Does the window weaken the soundproofing?
Less than you'd expect. The double-glazed panel uses two panes with an air gap between them — the same principle as professional studio observation windows. It performs significantly better than a single pane and better than an open gap. The curtain body (non-window area) performs identically to the KK1455.
Does the window weaken the thermal insulation?
Glass conducts temperature more readily than cotton fill, so the window is the coldest point of the curtain. The double-glazed construction minimizes this considerably. If your only goal is maximum thermal blocking with no visibility needed, the KK1455 will edge it out — but for mixed needs, KK1456 is the right call.
Where is the window positioned on the curtain?
The window is set into the curtain body — check the product images for exact position on your size. Generally it sits at comfortable standing eye level. Adjust the curtain rod height to move the window's effective sightline position up or down.
Can the glass break, and what happens if it does?
The glass is shatter-resistant — designed to resist breakage from normal handling and accidental impact. If it does break, it fractures into small blunt pieces rather than sharp shards. Contact service@arrowzoom.com for replacement options.
Will this completely block sound from the other room?
No acoustic curtain eliminates sound. The Soundproof Curtain PRO with Window significantly dampens noise passing through door gaps and the door assembly — most buyers report a noticeable and practical difference. For full room-to-room isolation you need wall mass (MLV, drywall, Green Glue) plus air sealing at every penetration.
What size should I order?
Measure your door width and height. Add at least 10–15 cm (4–6 in) to each side of the width and 5–10 cm (2–4 in) to the height. The curtain must overlap the frame on all sides — that overlap is what seals the gaps where noise and cold actually enter.
Is a curtain rod included?
No — the curtain rod, hooks, or ceiling track are not included. Use a rod rated for at least 15–20 kg — the glass panel makes this heavier than a standard curtain.
How is this different from the Door Kit PRO (KK1244)?
The Door Kit PRO (KK1244) uses self-adhesive acoustic panels applied directly to the door surface — STC-rated, permanent, panel-based. KK1456 is a hanging curtain with a view window — no adhesive, no permanent installation, covers the frame gaps panels can't reach, and gives you visibility. They solve different problems and can be used together.
Can I use this on a sliding door or garage door?
Yes — use a ceiling-mounted track. For wide openings, use two panels side-by-side with a center overlap. Position each panel so the window is at a useful sightline height on both sides of the overlap.

What's the difference between impact and airborne noise? 🔊
What's the difference between impact and airborne noise? 🔊
1. Airborne Noise
- This travels through the air, like conversations, TV sounds, or barking dogs. When sound waves hit a building, they cause it to vibrate, transmitting through the structure.
2. Impact Noise
- This results from physical impacts on buildings, such as footsteps, slamming doors, or moving furniture. Impact noise can be harder to isolate, as these vibrations are stronger and travel further through dense materials.
What are decibels? 📏
What are decibels? 📏
Decibels are measured logarithmically (not as a percentage) . This means that every increase of 10dB on the scale is a tenfold increase in sound pressure level (SPL) . Near silence is 0dB 🤫, while a sound at 10dB is ten times louder!
- 30-40 dB = Soft music, whisper 🎶
- 60-80 dB = Office noise, traffic 🚗
- 85-100 dB (HARMFUL) = Subway, shouted convo, chainsaw ⚠️
- 100-140 dB (DANGEROUS) = Chainsaw, loud concert, racing, shooting range 🚨
