How are zip screens professionally measured? This is a question we regularly receive at Port of Altea. The short answer rarely consists of just one brand or model. For zip screens, the property, dimensions, sun, wind, and daily use must be considered together. In this article, we explain why the opening size, permanent obstacles, and unevenness are important.
Start with the problem you want to solve
Made-to-measure products are not ordered based on just one width and height. The left, middle, and right sides may differ, and obstacles must be checked in the final position.
Write down which windows, doors, or terrace areas are involved, at what time the problem occurs, and who will use the system. A bedroom has different requirements from a rental apartment, a large sliding door, or a terrace that is mainly used in the afternoon.
What makes zip screens technically different?
Zip screens are designed to keep the fabric enclosed in closed side guides. Zip guidance, fabric tension, dimensions, and wind class therefore require attention. Looking only at the visible material is insufficient; the components behind it determine whether the system operates smoothly, safely, and reliably.
On the Costa Blanca, direct sunlight, high surface temperatures, gusts of wind, and salt or sand often occur together. A product that works well in a sheltered setting may require a different configuration on a high or exposed terrace.
Measure before making your final choice
Photos and approximate dimensions are excellent for an initial discussion, but not for production. We measure the opening at multiple points and check frames, the façade, roller shutter boxes, door handles, downpipes, windowsills, power points, and unrestricted movement. On terraces, we also consider the sun’s position, the desired shade, and walking routes.
The installation side affects the final dimensions. Fitting within the reveal, onto the reveal, against the façade, or beneath a ceiling are technically different situations. A centimetre that seems unimportant on paper can determine whether a door can still open in reality.
Operation: practical rather than simply modern
Electric operation is convenient for large or frequently used systems. Solar power avoids new wiring in suitable situations. Manual operation remains logical for small dimensions and simple use. We also discuss who will use the product and whether individual, group, or sensor-based operation is preferred.
Automation helps, but does not completely remove responsibility. A wind sensor must be positioned and configured correctly and is not a guarantee against every sudden gust. If in doubt, retract the external sun protection.
What quality is not immediately visible?
Profile thickness, construction, bearings, motor power, fasteners, fabric tension, and replaceability are not always visible in an inspirational photo. Therefore, do not ask only about colour and delivery time, but also about the system construction, limitations, and maintenance.
A realistic quotation specifies the exact configuration, operation, and installation. With made-to-measure products, cheap becomes expensive especially when a product does not quite fit, cannot be properly secured, or causes daily frustration.
Maintenance in Spain
Remove loose sand before using water or a cloth. Clean profiles, guides, fabric, or mesh according to the product instructions and do not use aggressive solvents. Do not leave sun-screen fabric rolled up while wet for extended periods, and never force a system that is jammed.
After strong winds, check that everything is straight and moves freely. With motors, unusual noise is a reason to stop. For insect screens, keeping the bottom guide clean prevents the mesh from being pulled unevenly.
Common mistakes
- Ordering with approximate dimensions or based only on a photo.
- Considering wind, sun direction, and the installation surface only after choosing the product.
- Comparing a basic internet price with fully installed made-to-measure work.
- Choosing electric operation without planning the cable route, panel position, or controls.
- Continuing to operate a product that moves stiffly or hangs unevenly.
What changes for an apartment, villa, or holiday home?
In an apartment, the community’s rules, access via a lift or balcony, and a uniform façade appearance often play a role. For a villa, the exposed location, large widths, and multiple façade orientations are more important. For a holiday home, it also matters that guests or property managers can use the system safely without extensive instructions.
This also means that not every opening needs the same product. A bedroom may require blackout protection, a living room may need to retain the view, and a terrace may require a large shaded area. By considering these functions together, the colour and operation can remain consistent while the technology differs for each opening.
When is repairing sensible and when should you replace it?
For a young system with one worn component, repair may be the logical choice. This could involve adjustment, a motor, an operating component, or locally damaged mesh. When profiles are bent, several components show wear, or spare parts are no longer available, replacement may ultimately be more reliable and cost-effective.
First, have the cause of the problem established. Replacing only a motor will not help if a roller shutter runs unevenly; installing new fabric will not solve poor anchoring. The cause must be addressed before a new component is subjected to the same load again.
How should you assess samples and examples?
View fabric, profiles, or mesh outdoors and at different times of day. Bright sunlight makes colours appear lighter and shows the texture differently from artificial showroom lighting. With screen fabric, the view from inside to outside is also important. For insect mesh, pay attention to transparency, strength, and the distance at which the mesh remains visible.
Also ask how a large product is divided. A small sample says nothing about seams, box size, posts, or the relationship between width and projection. A technical drawing or clear confirmation of the dimensions prevents surprises after production.
Practical checklist for your appointment
- Take photos from inside and outside.
- Note the approximate width, height, and preferred operation.
- Indicate when sun, wind, or insects cause the most inconvenience.
- Mention existing roller shutters, sun protection, and power points.
- Discuss access, floor level, and permission from the community.
