Roller blinds or curtains are manufactured with an aluminum tube of different diameters and a winding mechanism with a chain or motor that makes it rise and remain rolled up in said tube. It can be manufactured in different types of fabric such as screen fabric that will filter the sun's rays and allow you to see the outside. Another type of widely used fabric is the translucent fabric, it is made of polyester in the same way as the screen fabric, with the difference that the second fabric has PVC added. For roller blinds or roller blinds, we have another fabric that, if you don't know it, will surprise you. It is the opaque fabric designed to prevent light and sun from entering the room where it is installed. It is usually used in hospitals and schools, although we can find this type of fabric for home use.

Within the line of roller blinds there are also the Dual Shade or Zebra blinds, also known as day and night, that work on a roll and have double fabric to be able to fulfill a more complete function than the normal roller blinds, this being one of the most used in modern environments.

Roller blinds are also called roller blinds and are made of metal, which is why they are called metal roller blinds. But this last type of curtains is not for decoration, but rather they are used to provide protection to premises, businesses and in the home sector they are usually used in vehicle garages.

There are ready-made roller blinds on the market, ready to hang in various sizes and finishes.

Vertical curtains are another element that we can choose to dress living rooms, dining rooms, or any other place we imagine. They can be used with the fabrics that we have mentioned in the roller blinds part. In this way the decorative element can acquire different colors, textures and properties, adapting to any place.

Vertical or vertical curtains can be operated in two ways. On the one hand, with a chain and a cord, the chain to move the curtain slats from one side to the other and the cord to rotate the slats 180°. In addition, we can operate them by motor, which can be with a remote control or a push button, therefore this makes their price higher in almost all parts of the world. This work requires being carried out by a specialist technician, so we will not be able to install them ourselves. They require prior electrical installation to be able to install the object.

Curtains and blinds are often used interchangeably, which causes confusion for many people. However, there is a distinct difference between these two types of window coverings.

Curtains are generally fabrics that are hung on a window to block light, provide privacy, or simply add a decorative touch to a room. On the other hand, blinds are made up of slats made of different materials, such as wood, vinyl, polyester or metal, which adjust to allow or block the entry of light and regulate privacy.[3]​.

Unlike curtains, blinds can also be adjusted at different angles to control the direction of light and ventilation.

It is important to note that the difference between curtains and blinds is not always clear to native Spanish speakers, which can lead to confusion in the terminology used.

Curtains are made from a variety of thick fabrics, each with a different degree of light absorption and heat-insulating qualities.[4]​ For maximum temperature control, the separation between the curtain and the window should be small, with minimal convection currents under or above the curtain. Various architectural structures around the curtain can minimize these drafts, but are usually only used to decorate and make rooms appear more welcoming.

A sheer curtain or net curtain is a curtain made from a translucent fabric, such as a loose polyester gauze, marquisette") or ninon"), silk or nylon, cotton lace, etc.[5]​[6][7][8][9] Sheer curtains allow most of the light to be transmitted through the fabric, the fabric of which provides a basic level of protection against UV rays while maintaining maximum visibility to the outside through the curtain. Sheer curtains are sometimes called "privacy curtains" for their ability to conceal; During the day, most sheer fabrics allow people inside the home to see outside, while preventing people outside the home from directly seeing inside. Due to the loose weave of sheer fabrics, these types of curtains offer very little thermal insulation.

Unlined fabrics provide the next level of thermal insulation and light absorption. Uncoated fabrics make up the vast majority of those used in curtains and are composed of a tightly woven fabric, usually a cotton/polyester blend, that is mostly opaque when viewed in ambient light. Uncoated fabrics provide a reasonable level of thermal insulation due to their tight weave, but are too thin to completely absorb intense light. Therefore, when you close uncoated fabric curtains to block direct sunlight, light is still visible through the curtain because its fabrics are shiny.

Coated fabrics consist of a standard uncoated fabric with an opaque rubber layer applied to the back of the fabric to improve light absorption. To create a coated fabric, a liquefied rubber polymer is applied in a single layer to an uncoated fabric and then dry-fused using a heated roller, much like a laser printer applies toner to a sheet of paper before dry-melting it. A fabric that has gone through the coating process once is considered a “1-pass coated” fabric, known anecdotally as “dim-out” or “blackout” due to the fabric's ability to absorb approximately 50-70% of a direct light source. To improve the light absorption of a fabric, it is possible to coat it up to a maximum of "3 layers", which is considered sufficient to block 100% of a direct light source, hence these fabrics are called "blocking coated".

Maximum light absorption and thermal insulation in a curtain is achieved by a lined curtain&action=edit&redlink=1 "Lining (seam) (not yet drafted)"), which usually consists of an uncoated fabric on the front to provide the look and feel of the curtain, with a separate coated fabric attached to the back to provide the insulating qualities. Coated fabric is often called lining, which simply refers to a coated fabric that does not have any particular color or pattern.

Curtains may be fastened with tiebacks (a loop&action=edit&redlink=1 "Noose (knot) (not yet drafted)") of fabric, cord, etc., placed around a curtain to hold it open to one side; It is usually passed through a ring on a hook fixed to the wall, and secured with a knot, button, or Velcro; often adorned with tassels) or can be closed and opened with rods called pull rods (plastic, wooden or metal rods that can be twisted and/or pulled) or curtain rod") that attach either to the track or the first hook. A curtain hook stopper is a device used to prevent the curtain from falling off the end of the curtain track.

Although some shades may employ pulley systems, they should not be confused with roller blinds or roller blinds. In general, one can speak of "window treatments"), which are window coverings or modifications, often with the goal of improving the aesthetics of the window and the room.

Mesopotamia

In ancient Mesopotamia, curtains had a wider range of applications and were used in both domestic and ceremonial contexts. They were typically made of woven textiles, such as wool or linen, and could be simple or decorated with intricate designs. They were used not only in homes, but also in temples, palaces and public buildings. One of the significant uses of curtains in Mesopotamian architecture was in temple complexes. They were used to divide sacred spaces within temples, separating areas accessible only to priests and royalty from the general public. These curtains had ritual purposes, marking areas where only the highest ranking individuals were allowed to enter. In palatial settings, curtains were used to decorate stately entrances and ceremonial halls, adding splendor to official meetings and events. They were also used as room dividers in private residences, providing privacy and helping to control the internal climate.[10]​.

Ancient Greece

In ancient Greek society, curtains played an important role primarily in domestic settings rather than public spaces. They were used in homes to provide privacy, regulate light and offer a feeling of security. Greek houses generally had openings such as doors and windows that could be covered with curtains made of linen or other fabrics. These curtains were often dyed in various colors and sometimes adorned with decorative patterns. Curtains in Greek homes served practical purposes such as protecting the interior from intense sun and wind. They also played a role in delimiting private spaces within houses. In wealthier homes, curtains may have been more elaborate and used as a symbol of status and luxury.[11]​.

Rome

From remains found in excavations at Olynthus, Pompeii and Herculaneum, portiers, a curtain hung over a door, appear to have been used as room dividers in classical antiquity. Mosaics from the 2nd to 6th centuries show curtains suspended from rods passing through arches.[12]​.

England

In England, curtains began to replace wooden shutters towards the end of the century.[13] In medieval England, the first form of window covering consisted of leather panels strung on iron rods. Over time, they were replaced by woven wool panels. During the reign of Elizabeth I, ornately decorated Italian Renaissance fabrics such as brocades, velvets, and damasks began to be imported. These ornate fabrics, as well as those decorated with crewel embroidery, were used in curtains during the English Elizabethan and Jacobean periods. Solid wood shutters were used during cold seasons.[14]​.

Fatimid Caliphate

In the Fatimid Caliphate, a curtain known as sitr ("veil") was used to conceal the caliph at the beginning of an audience session (majlis).[15] A servant known as the ṣāḥib al-sitr (or muṭawallī al-sitr) would then pull it back to reveal the caliph seated on his throne. [15]​ The sahib al-sitr also performed the functions of chamberlain, master of ceremonies and bearer of the caliph's sword, and was often chosen from among mamluks of Saqaliba origin.[15]​.

Another type of curtain (not) common in towns and that is placed at the entrance of mansions or establishments to prevent insects from entering are the manuelada curtains. They are made with multiple pieces of plastic in the shape of a penne macaroni and a wire with hooks running through them so they can be hooked together. With these pieces, multiple strips are made until the entire entrance is covered.
