Roller shutters and blinds for window insulation. What are thermal curtains: types and application Insulated curtains for windows
With the onset of cold seasons, not only the biorhythms of the human body change, but also the mood: the world around us becomes colder, grayer and cloudier. More than ever, we begin to appreciate the pleasant, cute and cozy little things of a warm home. It's time to create an atmosphere of protection from winter cold in your apartment. You cannot do without changing your window “clothes”; you need to purchase a set of curtains for bad weather.
Curtains for bad weather
Insulating windows with curtains for the winter
In the store, among the variety of structures, colors, types of curtain fabrics, it’s easy to get confused. The weightless, butterfly-bright summer options are especially fascinating, but winter, warm curtains are made from completely different types of fabric:
- Texture. Forget about flying, flowing fabrics; among the latest innovations is the use of soft, lightly piled and “shaggy” fabric (chenille). Those who like to soak up the warmth of long evenings with a cup of tea will be delighted by the quilted material for winter curtains with padding polyester lining. Classic models – jacquard fabrics – remain relevant. Their convex designs with clear, three-dimensional lines turn the window opening into a work of art.
- Color. The variegation and riot of colors are appropriate for the hot, bright summer months - such curtains in inclement weather will only cause nostalgia for the holidays and slight irritation.
Curtains should be thick (like clothing) and warm (like sunlight). Such products will not only satisfy our increased need for comfort and coziness, but will also stop the pervasive flow of icy air.
The highest quality multi-chamber windows let the cold in to one degree or another. Warm air leaves the room in winter through gaps and cracks; heat loss also occurs in the form of radiation through transparent window glass. Additional insulation and protection of windows are thick, heavy curtains of light warm colors, which during this period are used not only for decoration. Curtains for insulating windows become an element of comprehensive protection of the house from bad weather and cold.

Necessary parameters of winter curtains
When choosing the decor of window openings for the cold season, you need to take into account the following product characteristics:
- Color spectrum. With the onset of autumn, the intensity of lighting outside the windows and the duration of daylight hours change. Therefore, it is important to transform the gray twilight flowing through the glass into a semblance of sunlight. Warm curtains for windows will help you cope with this task with the help of correctly selected colors.
Color spectrum
Designers advise choosing warm shades of yellow, orange, beige and terracotta.
The less natural light there is in the room, the more intense and saturated colors the window design will require.
Don't be afraid to experiment with hot, sultry shades.
Avoid deep, dark colors - such winter curtains will create a gloomy, heavy mood in a dimly lit room.
- Texture of the material. The play of light will be created by curtain fabric with a glossy, shiny surface. Reflecting glare and reflections will add a festive and mischievous mood to a gray day.
The density of the fabric is important. In the presence of drafts, impenetrable, heavy curtains will stop the flow of cold air penetrating through small cracks and prevent heat from leaving the heated room.
- There are different types of winter curtains depending on the number of layers of fabric used in sewing. Curtains can be made with lining. An interesting combination is a thick lining and a light, weightless covering (for example, organza). The lower fabric adds volume to the product and protects the thin upper fabric from mechanical damage.
Curtain models are produced from 2-3 layers of fabric of different textures. You can play up the color scheme by using several shades of the same type of material.
Sewn together, the canvases are fixed on the cornice. The multi-layer design allows you to change the mood of the room in a short time: it is enough to replace the top fabric that has become boring (or does not correspond to the internal condition).

In addition, this “design” has increased protective qualities:
- Cold air is not able to penetrate through several layers of material; warm curtains from the wind are an insurmountable barrier.
- An additional insulating air cushion is created between the layers. The curtain protects and maintains the internal temperature of the room using the principle of a thermos.
But don’t forget about the cornices: they carry additional load. The fastenings must be reliable in order to withstand the impressive weight of several pieces of fabric.
Winter curtain sizes
Now we determine the size of the seasonal set of curtains. Radiators in most rooms are located under the window sill. Long winter curtains cover their surface, which significantly reduces the heat transfer of heating devices. And if we are talking about dense, multi-layered fabric used for warm curtains, then the protective qualities will turn into a huge drawback: without allowing cold air to pass through from the windows, they at the same time do not allow radiators to heat the room.
Therefore, the optimal length of the winter set (so as not to cover the radiator with curtains) is a few centimeters below the window sill:
- You can make warm curtains for your home in the right size to order.
- Vertical dimensions are varied using decorative fasteners. The lower part of the curtains is beautifully draped or picked up and fixed in the desired position with clips.
- There is another option: transformable curtains. Buttons are sewn onto the middle of the curtain along a horizontal line, and the lower edge of the product is “equipped” with eyelets. The length of the curtain is adjusted as needed: with the onset of cold weather, the hinges are fastened, and the curtain acquires the required length, revealing the surface of the radiator.
In the winter months, the lambrequin also performs not only an aesthetic, but also an insulating function, being an obstacle to cold air at the top of the window. But here it is important to maintain the style of the room: this decorative element will not “make friends” with the modern, clear and laconic design of the room. And with a low ceiling height, a lambrequin will emphasize this lack of a room.

Screen in the inter-glass space
The thermal protection of windows can be increased by placing various screens in the inter-glass space. This method is based on the fact that when installing a screen, the temperature difference between nearby surfaces decreases and the intensity of the movement of air molecules and, consequently, convective heat transfer decreases. In addition, in some cases, when creating narrow air gaps, the speed of ascending air flows is slowed down by descending ones, which reduces heat transfer by convection. The screen installed in the inter-glass space also reduces the radiant component of the heat flow.
Curtaining light openings with devices placed between the glazing allows not only to reduce heat loss through the glazing in the cold season, but also to regulate the illumination to some extent.
Rice. 4. Interglazed curtain-blinds:
1 - aluminum plate; 2 - flexible connection; 3 - box; 4 - cord.
Commercially produced blinds can also be used for standard windows with paired and split sashes.
It is possible to place a roll-up curtain in the inter-glass space, which has an elastic screen made of metallized film that is wound on a drum. At the end of the drum there is a reel with a cord, the end of which is released through holes in the binding into the room.
Rice. 5. Roll Up Curtain:
1 - screen; 2 - drum; 3 - cord.
Also of interest is a combined curtain located in the inter-glass space, consisting of 2 panels connected to each other. Each of the canvases is attached to coils, one of which is located in the upper and the other in the lower part of the light opening. One of the canvases is made of transparent fabric or metallized film, the other is made of light-proof material. A transparent canvas is installed in the window during the daytime, and a dark one - in the evening or at night. In addition to reducing heat loss through the window in the cold season, the combined curtain can also be used in the summer as a sun protection device (when installing a sheet of metallized film).
Rice. 6. Combination screen curtain:
1 - upper drum; 2 - canvas made of translucent fabric or metallized film; 3 - lower drum; 4 - opaque dark fabric; 5 - cord.
Heat loss through windows can be significantly reduced by using a volumetric curtain located between the glass with a screen made of folded metallized fabrics. The screen sheets are made of metallized film, and the inner sheet can be made of transparent film. The screen of a volumetric curtain is lifted using a cord attached by a rail to the bottom edge of the screen and collected in a bag at the top of the window.
Rice. 7. Curtain with volumetric screen:
1 - screen made of folded fabrics; 2 - bar; 3 - cord.
Analysis of the heat-protective characteristics of screen designs showed that the most effective volumetric curtain allows reducing heat loss by 38%. Curtains-blinds installed in the inter-glass space can increase the thermal insulation capacity of windows by 1719%, and roll-up transparent curtains made of polyethylene film or fabric by an average of 28%.
With the onset of cold seasons, not only the biorhythms of the human body change, but also the mood: the world around us becomes colder, grayer and cloudier. More than ever, we begin to appreciate the pleasant, cute and cozy little things of a warm home. It's time to create an atmosphere of protection from winter cold in your apartment.
