Enjoy more peace, warmth and security with the Flenaro thermal curtain made to measure. Its particularly heavy, three-layer fabric construction combines a velvety soft flannel fleece surface with an insulating cotton blend filling and a dense blackout backing. The result is a voluminous, pleasantly soft thermal curtain that combines thermal insulation, blackout and additional privacy protection in an elegant design.
Whether for the bedroom, living room, children's room or as a flexible room divider - Flenaro creates a cozy atmosphere and supports living comfort in every season.
Flenaro is one of the particularly heavy thermal curtains. The flannel fleece front already has a basis weight of approx. 350 g/m². Combined with the insulating middle layer and dense blackout backing, the result is a heavy fabric construction with a total basis weight of approximately 600 g/m² or more.
For comparison: According to the product information, a curtain in a reference size of 55 × 84 inches weighs approximately 1.8 kg. The actual weight of a custom-made curtain depends on the dimensions chosen and the finish.
The high fabric density ensures a voluminous drape and supports the insulating properties of the curtain.
The high-quality thermal fabric consists of three functional layers:
The multi-layered workmanship combines a soft, homely look with the functional quality of a particularly heavy thermal curtain.
The thick fleece surface and insulating padding create an additional barrier in front of windows and doors. In winter, the made-to-measure heavy thermal curtain can reduce heat loss and mitigate the influence of cold drafts.
In summer, the dense fabric structure can help limit heat gain from sunlight. In this way, Flenaro supports a more pleasant indoor climate and ensures more comfort in every season.
The integrated blackout back is designed to completely block light, according to the material. Together with the heavy fabric layers, it offers particularly strong blackout and reliable privacy protection.
Flenaro is therefore particularly suitable for bedrooms, children's rooms or rooms in which disturbing daylight needs to be reduced. The dense fabric construction can also reduce light and direct sunlight.
Please note: The actual room darkening also depends on the installation. Light can still enter the room on the sides, at the top or below the curtain.
The particularly heavy, three-layer construction with thick cotton blend padding can dampen everyday ambient noise and contribute to more pleasant room acoustics.
Whether it's street noise, noises from adjacent living areas or general background noise - the heavy fabric can support acoustic living comfort. This property is particularly advantageous in bedrooms, studies and relaxation rooms.
The noise reduction that can actually be achieved depends on the room design, installation and the respective sound sources. The curtain does not replace structural sound insulation.
The fluffy flannel fleece surface gives Flenaro a luxurious, warm feel. The heavy fabric is soft and voluminous and creates a cozy spatial effect.
Available in Beige and Gray, Flenaro can be combined in many ways. Beige creates a warm, harmonious atmosphere, while gray goes perfectly with modern, minimalist and classic living styles.
Flenaro is suitable for bedrooms, living rooms, children's rooms, studies and large window fronts. The heavy fabric also offers practical advantages as a thermal door curtain or flexible room divider.
In open living areas, Flenaro can visually separate individual areas from each other and create additional privacy. In front of drafty doors or passageways, the dense fabric structure can help reduce unwanted air movement.
Each Flenaro thermal curtain is manufactured to your individual dimensions. Choose the right width, height and hanging type for your living space.
For an even, decorative fold, we recommend allowing sufficient fabric allowance when selecting the curtain width. Due to the high weight of the fabric, the curtain rod or curtain rail used should be suitable for heavy curtains.
Curtain rods and additional curtain rings are not included. The color of the free tieback may vary and differ from the selected curtain color.
The flannel thermal curtain is suitable for gentle machine washing. We recommend washing cold on a gentle cycle to protect the soft surface and multi-layered fabric structure. Then hang it up to dry.
Due to the heavy weight of the fabric, you should check the permitted load of your washing machine before machine washing.
Please note: Due to different screen settings and lighting conditions, actual colors may vary slightly from the product images. Please check your custom measurements carefully before ordering.

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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
