Custom-made vertical blinds on the Costa Blanca

Custom-made vertical blinds on the Costa Blanca provide compact light and privacy control close to the window. For customers who want to open, close, and tilt wide windows and sliding doors flexibly, the fabric, profiles, controls, and window function must be designed as one system.

This guide covers fabric, PVC, and electric vertical blinds for sliding doors and large windows on the Costa Blanca and helps you make a choice that is both attractive and technically suitable for the Costa Blanca.

Custom-made pleated shades and Duette: start with the window

Pleated and Duette systems are compact and versatile, but the final result depends heavily on the window profile, controls, fabric properties, and installation. A beautiful sample alone says nothing about unobstructed window operation or evening privacy.

For customers who want to open, close, and tilt wide windows and sliding doors flexibly, the aim is to coordinate the blind material, width, rotation position, rail, stacking side, and controls with the circulation path. That is why we assess the function first and only then the color, pleat height, profile, and technical configuration.

Create a priority list for each window covering privacy, light, heat, blackout, and operation. This prevents an attractive fabric from being chosen before the most important function has been technically resolved.

For vertical blinds on the Costa Blanca, we consider this component together with slat material, width, tilt angle, track, stacking side and operation, coordinating them with the circulation route. Record the choices for each window in writing so that the fabric, profile and operation are not based on assumptions during production and installation.

The difference between pleated shades and Duette

A pleated fabric consists of a single folded layer. Duette uses a honeycomb construction with air pockets and often internally concealed cords. This creates a different appearance and can affect comfort and light control.

For vertical blinds, we compare not only the names but also visible cord holes, cell structure, stack, fabric tension, maintenance, and suitability for the desired shape.

View both materials at full scale. Duette’s honeycomb structure looks calmer because the internal cords are less visible, while a single pleat often appears lighter and more delicate.

Transparent, light-filtering, dim-out, or blackout

Fabrics differ in transparency, color, coating, and density. Transparent fabrics maintain more contact with the outdoors; light-filtering fabrics soften the light; dim-out fabrics reduce it more strongly; and blackout fabrics allow virtually no light through the material.

For sliding doors, tall windows, living rooms, offices, hotels, apartments, and villas, we assess materials, fabrics, profiles, and transparencies that suit the space, solar exposure, privacy needs, and desired appearance. Test the actual sample against the window at different times, because evening lighting can significantly change privacy and color.

Ask about the reverse side and any coating. Two fabrics that look identical from the room side can differ significantly outdoors, in bright sunlight, and in terms of heat performance.

Top-down bottom-up and privacy

A movable top and bottom profile makes it possible to screen the middle of the window while allowing daylight in through the top. This is useful for street-facing windows, bathrooms, and homes opposite one another.

Determine the privacy height both seated and standing. For Costa Blanca vertical blinds, the desired intermediate position must be reachable, stable, and practical for everyday use.

Walk past the window outside with the interior lights on as well. This simple practical test gives a more accurate impression of privacy than general terms in a catalog.

Insulation, sun, and heat

The honeycomb structure of Duette can create an additional air layer on the inside of the glass. The actual effect depends on the fabric, cell, installation, gap, glazing, and use. Interior shading remains thermally different from exterior shading.

In strong sunlight, we also compare screens or shutters. Mark out active doors, stack locations, and operating sides beforehand, and measure the ceiling and floor across the full width. This prevents claims that a single product can meet every requirement under all conditions.

Close interior blinds before the glass and room have fully heated up. Using them in good time helps maintain comfort, but does not replace suitable glazing, ventilation, or exterior shading.

Accurate measuring

Measure the width and height at several points and check that the glazing beads and recesses are straight. Clearly indicate whether the measurement is taken across the glass, between the glazing beads, on the sash, or across the complete frame.

For this application, we check the active door, stack side, slat width, ceiling, floor height, wind, privacy, safety, and rail load. With multiple adjoining systems or unusual windows, professional measuring is the safest option.

For multiple windows, use a measurement sheet with unique window codes. Frames that look identical can differ by several millimeters in the glazing bead, handle, or available opening space.

Profiles, cords, and tension wires

The top, bottom, and intermediate profiles determine how the system moves. Tension wires keep window-mounted configurations stable when the window is turned or tilted. The profile color affects the overall appearance just as much as the fabric.

Check the fixing points, unobstructed handles, and alignment of all profiles. Even a slight tilt is immediately visible on horizontal components.

Choose the profile color carefully. A profile in the frame color blends in visually; contrast emphasizes the horizontal lines and can visually divide a small window.

Mounting on the glazing bead, sash, wall, or ceiling

Mounting close to the glass is compact and often moves with the window. Wall or ceiling mounting can provide greater overlap, but requires clearance for the window sash, stack, and operating mechanism.

The suitable configuration can be installed in the recess, on the frame, wall, or ceiling with appropriate fixings and sufficient clearance for windows, doors, air conditioning, and shutters to operate freely. Mark out the position beforehand and test each moving window in its fully open position.

Check the actual substrate before choosing fastening materials. Plastic, aluminum, wood, stone, and hollow walls each require a different installation approach.

Stack height and clear window opening

A raised pleated blind disappears into a compact stack, but not completely. The height, fabric type, number of layers, and profiles determine how much space is needed at the top.

For doors and tall windows, the stack must remain outside the clear opening. Ask for the expected dimensions rather than assuming a small showroom sample.

View the product fully open, half-open, and closed. The frequently used intermediate position in particular determines whether the stack, handle, and sightline are comfortable in everyday use.

Manual, cordless, or electric

The possible operating methods are manual, safe cord operation, or motorization, depending on the system, size, weight, power supply, and daily use. Handles are intuitive when they remain accessible; cords require safety devices; motorization is helpful for high or numerous systems.

Record who will use the product, which intermediate positions are needed, and whether the controls remain accessible behind furniture, a bathtub, a kitchen counter, or a desk.

For motorized systems, end positions, groups, transmitters, and power supply must be tested and documented during handover. Also keep information about charging, resetting, and manual emergency operation.

Child safety

Loose cords and loops must remain out of children’s reach. Use the prescribed safety devices or, where possible, choose cordless or motorized operation.

Do not place a bed, cot, or climbing furniture near the controls. Safety remains part of the installation and must not be removed for a cleaner look.

After installation, check all safety devices and do not rearrange the furniture in a way that could still allow a child to reach cords or moving profiles.

Moisture and ventilation

Not every fabric, coating, or profile combination is suitable for prolonged condensation or splashing. Even moisture-resistant window coverings require ventilation and proper drying.

Check the exact material recommendations. Do not leave a wet system rolled or folded up compactly for extended periods, and install electrical components only where technically permitted.

Ensure bathroom and kitchen windows are adequately ventilated. Moisture that remains trapped between the fabric, glass, and profile for extended periods can accelerate soiling and material stress.

Tilt-and-turn and sliding windows

Window coverings must preserve the window’s original function. Check the handle, tilt angle, ventilation grille, insect screen, and any collision with the recess or adjacent sash.

For vertical blinds, window-mounted installation can be very practical, provided the profile and guide are compatible. Always test the window fully open before production.

Open each window as far as possible during the survey. A difference of a few centimeters can determine whether the window covering, insect screen, ventilation, or cleaning will function smoothly later.

Unusual and non-standard window shapes

Pleated and Duette blinds are available for some triangular, trapezoidal, or roof windows, but not every shape can open fully or use the same operating method.

A template, drawing, or specialist survey may be necessary. Discuss in advance which part moves and where a fixed section of fabric will remain visible.

For unusual shapes, ask for a clear sketch showing the open and closed positions. A system can be made to fit, although its range of movement may be more limited than with a rectangle.

Combining curtains and sun protection

A window-mounted system can provide privacy and regulate sunlight during the day, while curtains soften the entire wall and provide additional closure in the evening. Shutters or screens can perform a different thermal function outside.

A useful comparison includes curtains, roller blinds, Venetian blinds, pleated blinds, Duette blinds, and other suitable window coverings. Combine systems only when they solve different functions and do not interfere with one another during movement and maintenance.

When planning double window coverings, allow sufficient space. Curtain fabric must not constantly rub against profiles, and both systems must remain accessible for cleaning and servicing.

Color, texture, and profile finish

A light fabric looks airy but can appear brighter in backlight; dark colors create a stronger visual block. The profile, handle, and cords should be deliberately matched to the window frame or fabric.

View samples vertically alongside the floor, wall, and window frame. The undertone of white, sand, and gray is strongly influenced by warm daylight on the Costa Blanca.

Order visible components as a single color package. White is not always the same white, and warm-gray profiles can stand out noticeably next to a cool aluminum window frame.

Maintenance and lifespan

Dust the fabric carefully and regularly, and follow the maintenance instructions exactly. Not every pleated or coated fabric may be washed or wet-cleaned.

Do not force profiles when a cord, handle, or fabric gets caught somewhere. Correcting the issue early prevents permanent creases or misalignment.

Keep the fabric name, color number, system type, and operating information. This makes future extensions or replacements much easier and prevents having to search using only an old photo.

Avoiding common mistakes

An important risk is having the package parked on the wrong side or installing a long rail without enough load-bearing points. Other mistakes include forgetting the system depth, measuring only with the window closed, failing to choose the profile color, and judging light blocking solely by the fabric name.

Work in a fixed order: function, window type, fabric, operation, installation, measurement check and only then production. Made-to-measure products cannot easily be returned after a measurement error.

Have a second person check the complete order line for each window: dimensions, configuration, fabric, profile, operation, opening direction and installation. This check prevents costly made-to-measure errors.

What determines the price?

The price depends on width, height, fabric group, configuration, number of profiles, operation, motorisation and installation. Unusual shapes and great heights require additional technical work and a site survey.

For an indication, send photos, approximate dimensions, location and intended function. After final measuring, the specification and complete price can be confirmed.

Only compare quotes when the fabric group, system, operation, installation and electrical preparation are described on an equal basis. A bare product price is not a complete made-to-measure solution.

Advice and installation from La Nucía

Port of Altea provides advice from its showroom in La Nucía and works across a large part of the Costa Blanca.

We take strong sunlight, roller shutter boxes, air conditioning, tiled surfaces, concrete substrates and frequently used patio doors into account. This ensures the solution fits not only on paper but also in the home.

Bring overview photos of the entire room to the showroom. This allows scale, colour, privacy, and coordination with furniture and curtains to be assessed at the same time.
