Custom Mosquito Screens: Types and How to Choose the Best for Your Window

Introduction: why you need mosquito screens in Granada and Malaga

Granada and Malaga are two of Spain's provinces with the highest presence of nuisance insects during the warm months (April-October). Mosquitoes, flies, wasps and moths are a constant annoyance that worsens near rivers (Genil, Guadalfeo), the agricultural Vega of Granada and the tropical coast. The most effective and healthy solution — without insecticides or electric devices — is a quality custom mosquito screen on every window and door.

At Tecnisun C.B. we install custom mosquito screens with powder-coated aluminium profiles and high-quality mesh. We work with 5 different types to cover any window, door or opening, with professional installation or supply-only so you can fit them yourself.

The 5 types of custom mosquito screens

Each screen type is designed for a specific use and window type. Here are the differences so you can choose wisely:

1. Roller screen: the most versatile

The roller screen is the most popular and versatile option. It retracts into an aluminium cassette at the top of the opening and rolls down vertically guided by tensioned cables or a side chain. When not needed, it disappears into the cassette. Compatible with casement, tilt-and-turn and top-hung windows of any material (PVC, aluminium, wood).

• Advantages: retracts when not in use, takes up no visual space, compatible with nearly any window.
• Limitations: not recommended for frequently used doors (mesh wears with repeated use).

2. Fixed screen: the simplest

The fixed screen mounts in an aluminium frame that press-fits into the window opening using metal clips or magnets. It has no moving parts, making it the simplest and most durable option. Ideal for windows that stay open all summer (bedrooms, living room) or as permanent protection.

• Advantages: simplest design, no mechanisms to break, easy to remove and replace for cleaning.
• Limitations: cannot retract, prevents full window opening.

3. Pleated screen: best for doors

The pleated screen folds horizontally like a concertina and stacks to one side of the opening. It is the ideal option for terrace doors, passage doors and large openings with frequent traffic. Opens and closes with one hand, sliding smoothly with no effort.

• Advantages: ideal for frequently used doors, retracts to the side, smooth one-hand operation.
• Limitations: more elaborate mechanism, requires a bottom guide on the floor.

4. Sliding screen: for sliding windows

The sliding screen glides horizontally along a track (usually the same track as the sliding window) and is the natural solution for aluminium or PVC sliding windows and doors. Its profile blends in aesthetically with the window.

• Advantages: perfect integration with sliding windows, smooth gliding, easy to remove for cleaning.
• Limitations: only suitable if a track is available on the window, does not retract.

5. Hinged screen: for doors with frequent use

The hinged screen works like a conventional door: it opens outward on side hinges and closes with a spring or magnet. It is the alternative to the pleated screen for frequently used doors, especially when pets need to go in and out.

• Advantages: full opening like a door, automatic spring closure, optional integrated pet flap.
• Limitations: needs clearance space (outward opening), can catch the wind without a stopper.

Mesh materials: standard, anti-pollen and pet-resistant

The mesh type is just as important as the frame type. At Tecnisun we work with three grades:

• Standard fibreglass mesh: the most common. 1.2×1.2 mm aperture that blocks mosquitoes, flies and moths. Grey colour for maximum transparency. Durable and easy to replace.
• TÜV anti-pollen mesh: 0.25×1.0 mm aperture that filters 99% of olive, grass and pellitory pollen particles (per TÜV Rheinland certification). Reduces dust and pollutant entry. Ideal for allergy sufferers in Granada, where olive pollen levels are very high in spring.
• Pet Screen metal mesh: PVC-coated stainless steel, much stronger than standard mesh. Withstands cat and dog scratches without tearing or deforming. Essential if you have pets.

How to measure your window for a custom screen

If you choose supply-only (no installation), you need to measure correctly:

• Step 1: measure the opening width (clear span) at three points: top, centre and bottom. Note the smallest measurement.
• Step 2: measure the opening height at three points: left, centre and right. Note the smallest measurement.
• Step 3: check the opening is square by measuring both diagonals. If they differ by more than 5 mm, note this on the order.
• Step 4: measure the available depth of the window frame (where the screen frame will sit). Minimum 15 mm for fixed, 25 mm for roller.

What shapes the quote for a mosquito screen?

We do not publish fixed prices, because every opening is different. What weighs most on the quote is:

• The screen type: a fixed screen is much simpler than a pleated or cassette roller screen.
• The dimensions: large openings and doors need more profile and more mesh.
• The mesh type: anti-pollen and Pet Screen are higher-grade technical meshes than the standard one.
• The profile finish: the powder-coat colour can match your existing joinery.
• With or without installation: you can order them fitted or supply-only.

Frequently asked questions about mosquito screens

How long do mosquito screens last?

The aluminium frame is very durable. The mesh is the part that wears: standard fibreglass mesh lasts several years and Pet Screen metal mesh considerably longer. When the mesh gets damaged, it can be re-meshed (replacing just the mesh without changing the frame).

Can they be fitted on old wooden windows?

Yes, fixed and roller screens adapt to any window type, including old wooden ones. They attach with screws or press-fit clips without damaging the original frame.

Which screen is best for terrace doors?

For frequently used doors: pleated (retracts to the side) or hinged (opens like a door). For sliding terrace doors: sliding on the same track. If you have pets: hinged with integrated pet flap.

Is the quote free?

Yes: the online quote is free and without obligation, based on your measurements and photos. The on-site technical visit has a cost, which we tell you before arranging it.
