Frequently Asked Questions about Window Fly Screens
What is the best way to keep insects out of my kitchen without blocking the breeze?
A fly screen is the only solution that genuinely does both — it blocks insects while allowing air to pass through the mesh freely. Unlike a solid blind or a closed window, the open weave of a fly screen creates no meaningful resistance to natural airflow. You get the breeze; the insects don't get in.
The Phiferglass® mesh used in our roller fly screens has an open area of approximately 60% — meaning that nearly two thirds of the mesh surface is open space rather than fibre. At normal wind speeds, that translates to airflow that is functionally equivalent to an unscreened window. The mesh intercepts insects physically without acting as a barrier to ventilation.
For kitchens in particular, a fly screen is also the recommended method of insect control under Food Standards Agency food hygiene guidance, which identifies physical barriers as the primary means of preventing insect access to food preparation areas.
A roller fly screen is the most practical daily-use solution for a kitchen window — the mesh deploys in seconds when the window goes open and retracts completely out of sight when it doesn't.
How do I stop flies ruining BBQ food with the kitchen window open?
Few things spoil a summer afternoon faster than flies settling on food the moment the kitchen window goes open. It's a familiar problem — and a straightforward one to solve.
A roller fly screen fitted to the kitchen window creates a full-width mesh barrier that lets air and cooking smells out while keeping flies firmly out. For food preparation areas, it's also worth noting that the Food Standards Agency recommends physical insect barriers as a primary control measure in kitchens where food is handled — a roller screen satisfies that requirement without obstructing ventilation or natural light.
If your back door stays open during a BBQ, the window screen alone won't be enough. A roller fly screen door covers the full door aperture on the same spring-and-magnetic-close mechanism, keeping the route from garden to kitchen protected while guests move freely between the two.
What is the difference between a fixed fly screen and a retractable one?
The core difference is visibility and lifespan — and the right choice depends on how you use your windows.
A fixed fly screen sits permanently in the window aperture, the mesh is held in place by a rigid frame that sits in the aperture on brackets or hinges. The mesh screen is always present and visible whether the window is open or closed, which means the mesh is exposed to UV light, dust, and impact year-round. Fixed screens are generally the lower-cost option upfront, and if aesthetics and convenience aren't major concerns, they do the job well. The trade-off is that the mesh degrades faster than a protected retractable mesh, and the frame is always visible, and the screen will need to be removed or hinged open to access the window itself. A fixed frame fly screen can be removed out of season, but you will need to find somewhere to store it.
A retractable roller fly screen works differently. The mesh is housed in an aluminium cassette at the top of the window and pulls down only when needed. When the window is closed, the mesh retracts completely out of sight — protecting it from UV exposure, dust, and incidental contact. This has a direct impact on lifespan: fibreglass roller mesh can last up to 15 years, considerably longer than an equivalent fixed screen in the same location.
For windows you open occasionally, a fixed screen is a practical, cost-effective choice. For windows in frequent daily use, south-facing aspects, or anywhere appearance matters — a kitchen, a living room, a period property — the retractable roller screen is the more considered solution. You get insect protection when you need it and an unobstructed window when you don't.
What can I put on my windows to let air in but keep mosquitoes out?
A fly screen is the most effective solution — it allows air to circulate freely while the mesh physically blocks insects from entering. For mosquitoes, standard 18×16 insect mesh (18 strands per inch horizontally, 16 vertically) provides an aperture small enough to stop them reliably. This is the mesh used in our standard roller fly screens and is more than adequate for the mosquito species found across the UK.
If you're in an area with smaller biting insects — midges in particular — it's worth stepping up to our midge-proof roller fly screen, which uses a finer 20×30 mesh with an aperture of 0.86×0.45mm. This stops midges and other small flying insects that standard mesh will not catch.
For windows you open regularly throughout the day, a roller screen is the most practical choice — the mesh pulls down when you need it and retracts neatly into the cassette when you don't, so ventilation and insect protection work on your terms rather than as a fixed compromise.
What is the best type of fly screen?
Aluminium frames and fibreglass mesh are the industry standard for long-lasting window fly screens. Its mesh is resistant to rust, corrosion, and stains, and it can be stretched without breaking. However, a more modern and discrete alternative is the roller fly screen, which can be installed around the opening part of the window or within the recess. Similar to a roller blind, the mesh rolls onto a tube houses within a cassette at the top of the window. When the window is open, the mesh can be pulled down to cover the window. When not in use, it hides away within the cassette. This makes the screen both discrete and long-lasting since for the majority of the time the mesh is protected within the cassette!
Are magnetic fly screens good?
Magnetic fly screens are a nice low-cost solution preventing insects from entering the home. They can be fitted without screws, which makes them ideal for tenanted properties, or to take on holiday. They can be removed when not in use or out of season. However, the screen does require adhesive magnetic tape to be stuck to the fixing surface, which some people will not like.
Do window screens keep mosquitoes out?
Yes, window screens keep mosquitoes out. They not only keep mosquitoes, flies, and other insects outside, but they also let fresh air circulate inside, allowing you to keep your window open without running the danger of getting bitten. You should be aware that a standard 18x16 fly screen mesh will not keep out smaller insects found in some parts of Scotland, such as midges. For this, you should select a midge screen.
What is a bug screen?
A bug screen is a mesh-embedded frame that has been demonstrated to keep out insects such as mosquitoes, flies, and other pests. The objective of insect screens for doors and windows is to prevent unwanted creatures from entering through doors, windows, and openings.
What is a wood window screen?
A wood window screen is a type of insect screen that is designed to fit over the opening of a wooden window. The frame is made of wood and screen is made of a fine mesh material that keeps out flies, mosquitoes, and other flying insects while still allowing air to circulate. Wood window screens are available in a range of sizes to fit different window models and sizes.
Can I paint my wood window screen to match my window frame?
Yes, you can paint your wood window screen to match your window frame. The screen is made of a wooden frame and mesh material, so it can be painted using the same paint or stain that was used on your window frame. This is a great way to ensure that your screen matches your window frame and enhances the overall aesthetic appeal of your home.
Why should I consider using a fly screen for my windows?
A fly screen is an excellent addition to any home, serving the dual purpose of allowing fresh air in while keeping flies and other insects out. Ensuring comfort, hygiene and safety, a window or door fly screen normally allows you to enjoy natural light, a view out and ventilation without worrying about bugs or insects entering your home or business premises. Fly screens come in a range of styles and costs to suit every budget.
Are metal fly screens a suitable option for use in my home?
A metal fly screen would be an excellent choice for your home. They are available as standard-sized door screens or can be custom-made to your measurements, meaning they can be used for larger doors or smaller windows. They are incredibly durable and resistant to damage, making them ideal for areas with heavy usage such as kitchens and patios.

Can you provide a brief overview of the main advantages of installing fly screens?
Certainly, the primary advantage of installing fly screens is that they serve as a protective barrier against various flying and crawling pests including flies, mosquitoes, wasps, spiders and other bothersome insects. This reduces the likelihood of insects entering the home or business. For both homes and businesses, this ensures good hygiene in food preparation areas. It eliminates the nuisance, distraction and stress caused by flying pests buzzing around your property. For those with allergies to insect bites and stings fly screens are an essential safety barrier, preventing wasps and hornets from entering your home. Fly screens allow you to enjoy natural ventilation and cool breezes without worrying about insects or debris. This can be a particular relief at night time during warmer summer months, where it is otherwise necessary to keep windows closed creating a hot and stuffy environment which makes it impossible to get a good night's sleep.
Can I easily store my fly screens when they’re not in use?
Yes, you can opt for retractable fly screens, which are designed to automatically roll away into the cassette when not needed. This feature ensures they remain discreet and don’t obstruct your view, making them a practical choice for seasonal use or when you want to maintain the aesthetic of your windows. We also have ‘no drill’ roller fly screens which can easily be fully removed from the window. However, in general our roller fly screens are designed to be so discrete that they can be left installed.
