A season that runs from spring to November, persianas on every window and warm Atlantic evenings. These are the suppliers serving Portugal.
⟳ Updated August 2026Portugal's insect season is long: mosquitoes work the warm months from spring deep into autumn, and evenings on the varanda invite them in. Portuguese windows already juggle persianas and shutters, so any screen has to fit around them without drilling. Magnetic insect screens do exactly that. Here are the suppliers.
The dedicated Portuguese store in the family, cutting magnetic insect screens to measure for Portuguese windows. Built for homes balancing persianas, aluminium frames and long warm seasons.
The European hub of the network with the complete catalogue. The route for odd shapes, older townhouse windows and mixed orders across a whole Portuguese house.
The value tier of the same family for European buyers. Simple kits at friendly prices make it realistic to screen every bedroom before the season peaks.
The door specialist of the network. Varanda and terrace doors that stand open through Portuguese evenings get walk-through screens fixed panels cannot offer.
A major home improvement chain with stores across Portugal. A generalist for building and garden projects rather than a magnetic screen specialist.
No. Persianas run in their own tracks outside or within the frame, while the magnetic screen sits on a flat frame face inside. Both operate independently, so you can drop the persiana at night with the mesh still sealed.
Longer than most of Europe: warm coastal air keeps mosquitoes active from spring well into November in much of the country. That long season is why a removable screen still spends most of the year fitted in Portugal.
Yes, aluminium is one of the best surfaces for it. Clean the frame face, let it dry, press the strip on firmly and give the adhesive a day to cure before heavy use. It then holds season after season.
Sliding windows screen well: the panel mounts over the opening half on the frame face around it. You slide the glass behind the sealed mesh, so ventilation works normally while the screen stays put.
Sun is the main ageing force for any mesh, which is why quality screens use UV-stabilised material. Portuguese buyers should pick the better mesh grades and take panels down in the short winter to stretch their life further.
Very much so. Fit the strips once and the house becomes guest-ready in minutes each visit: snap the panels on, open everything to the sea air, and nobody spends the first night hunting mosquitoes. Between stays the panels store inside.
Yes. A marquise usually has sliding or hinged panes with flat frame faces, all of which take strips and panels. Screening the marquise turns it into a genuinely usable summer room after dark.
Not meaningfully. Mesh and magnets shrug off humid air, and salt film near the ocean rinses away with fresh water now and then. The adhesive, once cured on a clean frame, is unaffected by damp evenings.
The door. An open varanda door funnels mosquitoes straight into the lit living room, so pair window panels with a walk-through door screen. That combination closes the loop most Portuguese homes leave open.
Generally yes. Old wooden frames need the same preparation as anywhere: clean, dry, sound paint where the strip will sit. Custom cutting deals with the uneven sizes older Portuguese joinery often has.
Portugal's great luxury is the length of its warm season, and its small tax is what flies and mosquitoes do with all those months. From the first warm weeks of spring to the last mild nights of November, the windows want to be open and the insects agree.
Magnetic screens suit the Portuguese window, with its persianas and aluminium frames, better than anything that needs a drill.
Portuguese windows are already layered: glass, persiana, sometimes interior shutters too. The magnetic screen adds its layer without touching the others, because it lives on a flat frame face the persiana never uses. Night configuration becomes persiana down, window open behind it, mesh sealed, which is exactly the airflow-with-privacy arrangement Portuguese summers call for. Nothing is drilled into the frame, which matters on rented flats and on aluminium joinery nobody wants to pierce.
In northern Europe, screens work perhaps four months a year. In Portugal they earn their keep from spring into November, which makes the cost per protected evening about the lowest on the continent. It also means mesh quality matters more: choose UV-stabilised grades, since Portuguese sun is the real ageing force, and give panels their winter rest indoors during the short cool season. The strips stay on the frames, and the spring refit takes minutes for the whole house.
The same system covers the Lisbon flat with its correr sliders, the townhouse with old wooden frames, and the Algarve holiday house that fills with family in August. Sliding windows take a panel over the opening half; old joinery takes custom-cut sizes measured window by window; the holiday house takes strips fitted once and panels that snap on within minutes of arrival. Add a walk-through screen on the varanda door, because that door is where most Portuguese mosquito problems actually begin.
Measure in millimetres, order from the Portuguese store, and have the mesh up before the first warm spring week. The season is long; enjoy all of it with the windows open.
