The eyelets option suited our setup well, and the folds look natural. The quilted fabric is another reason I chose Keldora.

Keldora - Heavy Duty Quilted Thermal Custom Curtain
More warmth, privacy and living comfort: The Keldora thermal curtain made to measure impresses with its heavy, three-layer quilted structure with 405 g/m² and a functional black back. The combination of durable outer fabric, insulating padding and dense backing makes this curtain a practical solution for windows, doors and open living areas. The decorative diamond quilting gives it a timeless, structured look.
405 g/m² - Heavy three-layer quilted structure
Keldora consists of three coordinated layers: a robust outer fabric, thick insulating padding and a black back. With a fabric weight of approx. 405 g/m², this thermal curtain is particularly heavy and dimensionally stable. The even diamond quilting fixes the padding and ensures a harmonious fabric structure and a beautiful drape.
Heat-insulating and draft-reducing
The thick quilted filling forms an additional insulating layer in front of windows and doors. In winter, the heavy thermal curtain can reduce heat loss and reduce the influence of cold drafts. In summer it can help limit heat gain from solar radiation. The heavy fabric construction contributes to greater living comfort, especially on drafty doors, large window areas and passageways.
Black back for privacy and light reduction
The black back layer supports darkening and, together with the dense fabric structure, offers reliable privacy protection. Depending on the color variant, Keldora reduces the incidence of light by approx. 50-70%. The curtain is therefore particularly suitable for rooms in which a pleasantly subdued lighting atmosphere is desired.
Please note: Keldora is not a 100% blackout curtain. Light can pass through the fine puncture points of the stitching seams.
Noise-dampening fabric structure for more peace
Thanks to its heavy, padded construction, Keldora can dampen everyday ambient noise and have a positive effect on room acoustics. The curtain is particularly suitable for bedrooms, children's rooms, studies and living rooms on busy streets. The actual noise reduction depends on the room situation, the installation and the existing sound sources.
Versatile as a window, door and room divider curtain
Whether in front of large windows, on balcony doors, in hallways or as a flexible room divider - Keldora can be used in a variety of ways. The heavy fabric provides privacy and can help separate different living areas visually and thermally. Available in Beige and Gray, the simple quilted design blends harmoniously into modern and classic living spaces.
Individual made-to-measure with four suspension types
Each Keldora curtain is made to your individual dimensions. Choose the right width, height and hanging type for your home.
- Width: 100-500 cm
- Height: 60-265 cm
- Eyelets: Practical hanging with metal eyelets on a curtain rod
- Rod pull-through: Classic suspension directly on the curtain rod
- Hooks: Suspension with matching curtain hooks
- Multifunctional band: Flexible suspension with various fastening options
For a beautiful fold, we recommend allowing sufficient fabric allowance when selecting the curtain width.

FAQ – Made-to-Measure Curtains for Interiors
1. What does "custom-made curtain" mean at BTTO?
A custom-made curtain is individually manufactured according to your desired width and height specifications. At BTTO, you can select the fabric, color, header style, dimensions, and other details so that the curtain perfectly fits your window, curtain rod, or track.
2. What rooms are custom fabric curtains suitable for?
Custom-made fabric curtains are particularly suitable for living rooms, bedrooms, dining rooms, children's rooms, studies, and guest rooms. Depending on the type of fabric, they can be decorative, reduce light, provide privacy, or improve the room's acoustics with a softer feel.
3. How do I measure my curtains correctly?
First, measure the width of your curtain rod or track. For a beautiful drape, we generally recommend a fabric width of approximately 2 to 2.5 times the length of the rod or track. Depending on the mounting method, measure the height from the track, rod, or desired hanging height to the desired final height.
4. How much fabric width should I choose for nice pleats?
For a classic, soft drape, we recommend a total width of about 2 to 2.5 times the window or track width. If the curtain should appear rather smooth when closed, a smaller width can be chosen.
5. What curtain heading styles are there for fabric curtains?
At BTTO, different heading styles are available depending on the product, such as eyelets, multi-functional tape, curtain hooks, wave pleat, or rod pocket. The appropriate choice depends on whether you are using a curtain rod or a curtain track.
6. Are custom blackout curtains completely opaque?
Many BTTO blackout curtains are opaque and significantly reduce incoming light. The exact blackout effect depends on the fabric, color, weight, and installation. Darker fabric colors generally provide more blackout than lighter colors.
7. Do thermal curtains help against heat and cold?
Thermal curtains can help to reduce heat exchange at the window. In winter, they contribute to a more comfortable room temperature, while in summer they can reduce direct sunlight and heat exposure. They are not a substitute for structural insulation but can improve living comfort.
8. Can fabric curtains also reduce noise?
Heavy, densely woven fabric curtains can improve room acoustics and muffle sounds somewhat. Thicker fabrics and soundproof curtains are particularly suitable for bedrooms, studies, city apartments, or rooms located on busy streets.
9. Can I receive fabric samples before ordering?
Yes, at BTTO you can order fabric samples to better assess the color, texture, feel, and light effects in advance. This is particularly recommended if you want to compare several fabrics or precisely match the curtain to your interior design.
10. Are custom-made curtains returnable?
Since custom-made curtains are manufactured individually according to your specifications, they are generally excluded from regular returns. Please therefore carefully check the dimensions, fabric, color, and heading style before ordering. If you have any questions, the BTTO team will be happy to assist you in advance.
11. Which curtains are best suited for bedrooms?
For bedrooms, opaque blackout curtains or made-to-measure thermal curtains are particularly suitable. They reduce light, protect privacy, and create a quieter, cozier sleeping environment.
12. What curtains help against heat in summer?
Dense thermal curtains or blackout curtains can reduce direct sunlight and make the room feel more pleasant in summer. They are particularly helpful on large windows, south-facing windows, or skylights.
13. Which curtains are suitable for more peace and quiet in the room?
Heavy, densely woven fabric curtains and sound-insulating curtains can improve room acoustics and slightly dampen disruptive noises. They are particularly suitable for bedrooms, home offices, and city apartments.
14.Are your fabrics safe for children and pets?
Yes. Our fabrics are free from harmful substances and safe for everyday family use. Most of our materials are certified according to OEKO-TEX® Standard 100 and are therefore free from harmful substances.
15. How do I determine the correct curtain rod height?
As a general rule, mount the curtain rod 15–20 cm above the window frame to create a sense of height. For a floor-length look, let the curtains hang just above the floor (1–2 cm gap) or slightly pleat them for a more dramatic effect.
Here you will find a complete guide on how to measure curtains.
16. Can I order a custom size that is not listed on the website?
Yes, that's possible. Simply contact us , and we'll make curtains to your desired dimensions.
17. What is the difference between blackout, dim-out, and transparent fabrics?
- Blackout: Blocks 90-100% of light for maximum privacy and darkness.
- Blackout: Gently filters the light, reducing glare while maintaining some brightness.
- Transparent: Allows most light to pass through and offers minimal privacy with an airy look.
