Insect screens allow windows and doors to stay open during warm summer days and nights — without mosquitoes, flies or other insects. Fresh air and comfortable living without bites or disturbance.
We offer fixed, roller, plisé, sliding and bi-fold screens in ALU frames, made to measure for every window and door. Installation without drilling into load-bearing walls, fast delivery.

Fixed, roller, plisé and sliding screens for all types of windows and doors. Every system is made to measure in an ALU frame.
An insect screen is a fabric made from polyester or fibreglass threads with a density of 18×16 threads per cm². The gap between threads is small enough to stop mosquitoes, flies, moths and other insects, but large enough to let air through almost as freely as an open window.
The screen is fitted into a lightweight ALU frame that is mounted on the window frame, reveal or directly onto the wall. The frame is finished to match the window — white, brown, anthracite, silver or any RAL colour. The thin frame profile is virtually invisible through the glass.
Special fine-weave screens are also available for protection against pollen and small airborne allergens — ideal for allergy sufferers who cannot keep windows closed during the flowering season.

For every type of window and door there is a matching system — fixed, roller, sliding or bi-fold.
Screens in an ALU frame mounted directly onto the window frame. They do not open — permanently protected opening with maximum ventilation. Ideal for windows that are rarely opened fully.
A screen rolled onto a cylinder that is lowered and raised as needed. Compact, aesthetically clean appearance when raised. Mounted above the window, inside or outside. Manual or motorized.
An accordion-folded system without side guides. Ideal for non-standard window shapes — triangular, trapezoidal and roof windows. Fold into a compact package at the top or bottom of the window.
A screen on a sliding rail for balcony and terrace doors. Slides to the side and does not block the passage. Available for single and double sliding doors, in ALU and PVC frames.
A system that folds like an accordion for larger openings and entrance doors. Can be fully opened by pushing to the side. Suitable for terrace and entrance doors with frequent passage.
A frameless screen attached with magnets along the door edge. Closes automatically after passing through — no need to close manually. Easy to install and remove without drilling.
Screens are a simple, durable and economical solution that transforms the summer months — open windows, fresh air, zero insects.
Screen density (18×16 threads/cm²) lets air through but effectively stops mosquitoes, flies, moths and other insects. Sleep and relax with open windows — no bites, no disturbance.
Unlike closed windows, screens allow a free flow of fresh air. The room stays ventilated and cool without air conditioning — even on warm summer nights.
Thin ALU profiles and a discreet mesh are virtually invisible when looking through the window. Available in white, brown, anthracite and all RAL colours — matching every window and facade.
Most systems are installed with clips or screws without drilling into load-bearing walls. Easily removed for cleaning or winter storage — in minutes and without tools.
ALU frames are resistant to corrosion, UV rays and moisture. Polyester or fibreglass mesh does not rot, does not fade and retains its shape even after years of use.
Every screen is manufactured to the exact dimensions of the window or door. Non-standard shapes, angled openings and roof windows are no problem — we have a solution for every opening.
Screens are fitted to all types of windows and doors — from standard residential to commercial buildings.
