Which mesh type do you need?
All screens use the same slimline System 41 cassette and aluminium profiles. The only difference is the mesh — choose based on what you need to keep out.

Why Our Roller Fly Screens Are the UK's Most Trusted Choice
Newblinds.co.uk has been manufacturing and selling roller fly screens in the UK since 1994 — over 30 years of continuous refinement to a product that works. Our System 41 roller insect screen was developed specifically for the UK market, where most windows open outwards and screens are typically installed internally. The result is a screen as at home in a listed country cottage as in a modern commercial kitchen.
A Screen That Disappears When You Don't Need It
The System 41 comprises a 41mm roller cassette containing a roller tube, mesh and spring mechanism. The mesh is pulled over the window or door using colour-coded handles, running between 30×22mm guide rails. It pulls closed to the window sill — or, for opening lights without a sill, to an L-shaped closing profile. The spring-loaded mesh then rolls neatly back into the cassette the moment you close your window, protected from UV, dirt and damage until the next time you need it. There's no seasonal storage, no taking down, no fuss. Customers tell us their screens are still performing perfectly 10 to 15 years after installation.
Custom Made to Your Exact Size — No Trimming Required
Every roller fly screen for windows and every screen for single and double doors is hand-made to order in our UK factory using the measurements you enter on the product page. A poorly fitting screen isn't just aesthetically poor — it's functionally useless. Gaps around the edges are exactly where insects find their way in. By manufacturing to your precise dimensions, we eliminate that problem entirely.
Brush Pile Sealing — No Gaps for Insects to Pass Through
Integral brush pile strips line both side channels and the closing bar of every screen we make. When the mesh is pulled down, these brushes press gently against the mesh surface and the window frame, creating a continuous seal around the entire perimeter. It's the same principle used in draught-proofing, and it's highly effective — no gaps, nowhere for insects to enter.
Strong, Powder-Coated Aluminium Profiles — Built to Last
Unlike screens that use flimsy plastic or lightweight metal, our profiles are rigid, corrosion-proof aluminium with a strong powder-coated finish. Available in White (RAL9010), Brown (RAL8014) and Anthracite Grey (RAL7016). For contract or project requirements, additional RAL colours are available on request. Although most UK screens are installed internally — since most windows open outwards — our profiles are engineered to withstand year-round external installation without deterioration.
Mesh Can Be Replaced — Extending the Life of Your Frames
Unlike a flat-framed screen that must be discarded and replaced wholesale if the mesh is damaged, our roller screens are designed so the mesh can be replaced independently. The aluminium cassette and profiles — the expensive components — are covered by our 5-year guarantee and built to last considerably longer. This makes our screens a genuinely long-term investment.
Chainless Operation — Safer for Families
Our screens are entirely spring-operated with no cords or chains. Beyond that, every screen features our unique brake mechanism, which slows the recoil of the mesh when released — protecting the product from damage and eliminating the risk of trapped fingers.
Proven in Commercial and Residential Environments
Our system has been specified for long-term contracts with both the UK Ministry of Defence and the US Air Force. For food preparation businesses, our screens comply with EC Regulation 93/43 on hygiene in foodstuff preparation areas and meet FSA requirements.

Frequently Asked Questions
Everything you need to know about buying, fitting and using our roller fly screens.
Do retractable fly screens work?

They are an excellent way to keep unwelcome pests such as flies, wasps and creepy crawlies at bay without obstructing your view. No matter the size of your window apertures, retractable fly screens will not let you down.

Do your roller fly screens also include door fly screens for UK homes?
Yes, at NewBlinds, we do offer a range of roller door fly screens UK for our customers to choose from. A roller fly screen door uses the same components as a roller window screen, with the screen effectively turned on its side. The roller cassette is fixed at the side of the door, with guide rails on top and bottom. Single doors have a magnetic u-profile that the roller screen sliding bar snaps securely into. Double screens have a roller cassette on either side, pulling close to the middle, held in place with magnetic strips on each of the sliding bars. We ensure the utmost quality and durability in all our products so that you can enjoy a bug-free environment at your convenience in the UK.

However, if you encounter any challenges or need any form of assistance during your installation process, our team is always ready to offer support. Remember that the proper installation of your door screen is imperative to its functioning and longevity.
How does a pull-down screen work?
A pull-down screen is a type of retractable screen that can be mounted on a window or door frame. In the case of a window, the screen is housed in a cassette at the top of the frame and can be pulled down manually to cover the opening. For doors, the cassette is usually situated at the side, and pulled across. When not in use, the screen can be retracted back into the cassette, providing an unobstructed view. When pulled down (or across), the screen is held in place with a locking mechanism, usually a magnet or latch, and can be released with a simple touch to retract the screen.
Can you have nets and blinds together?
Yes, you can have fly screen nets and blinds for solar protection and decoration together. Insect net curtains or blinds can be used as a protective layer for windows and can be paired with other types of window treatments such as roller blinds or curtains for additional privacy and light control. Usually one of the solutions would be fitted in the recess or against the window opening, leaving space for the other solution to be positioned further forward in the recess or outside of the recess.
Can you see through net blinds?
Yes, net blinds are made from a fine mesh material that allows light and air to filter through while still providing privacy and protection against insects. However, the level of privacy depends on the thickness, colour and tightness of the mesh weave. For example, white mesh actually more visible than traditional grey mesh, and thus provides more of a visual barrier. There are different grades of mesh depending on what you wish to keep out - standard fly screen mesh is least visible and provides the best view out, whilst anti-pollen and anti midge nettings are both tighter weave, and made of thicker fibres in the case of midge netting, therefore the view out is slightly less.
How do retractable fly screens work?
A retractable fly screen is similar to a roller blind. Instead of decorative or shading fabric, fly screen mesh is used and rolls onto the tube, which is contained in an aluminium cassette. The blind itself is spring-loaded, and operated using a handle on the hem bar. For a window configuration, the screen runs in side channels, left and right and is pulled down to the window sill which creates the 4th side of the frame. When not in use, the mesh screen rolls away out of sight into the cassette. The cassette and side channels are slim-line and discrete in appearance so the screen is not visually obtrusive when in use or when rolled away.
What is the difference between a retractable screen door and a sliding screen door?
Retractable screen doors feature a spring loaded roller cassette on one side of the door into which the mesh rolls up out of the way. The screen is pulled across using a sliding bar, running in top and bottom rails, and latches into a magnetic profile. Sliding screen doors are flat framed screens containing mesh which slides in top and bottom channels. Of the two types of screens retractable screens are more discrete and tend to be long lasting.
How long do retractable screen doors last?
Since the mesh of the fly screen is retracted when it is not in use, the mesh fabric is protected the majority of the year from UV radiation, dirt, and weather elements. As a result, retractable screens will outlast ordinary flat framed screens by a large margin. In the winter, there is no need to remove and store the screens. We have customers that are still using their retractable roller fly screens 10 to 15 years after they were purchased. Although life span will of course depend on usage and fair treatment.
Are retractable fly screens good?
In comparison to other types of fly screens, such as framed window fly screens, velcro mesh screens, mesh panel screens and hinged door fly screens, retractable fly screens is an excellent solution. The main benefit of retractable fly screens is that when the window or door is not open, the mesh screen itself rolls away onto the tube that is concealed in the cassette. Because of course, your door is closed the majority of the time, especially out of the summer months, the screen is rolled away the majority of the time protecting it from damage and build up of dirt and grime. Screens that are permanently in place and have the mesh exposed 365 days per year are at greater risk of damage, both to the frames and to the mesh itself.
Can I use roller blinds as a type of fly screen for my windows?
Traditional roller blinds are not designed to serve as fly screens. However, our Roller Fly Screens are an excellent solution for keeping insects out while allowing fresh air to circulate. These screens use a roller mechanism similar to a roller blind but feature a fly screen mesh housed in a slim-line cassette. They are easy to install and run within side channels, ensuring a secure fit that prevents insects from entering through the window. When not in use, the mesh can be retracted into the cassette for cleanliness and protection, making them a practical and unobtrusive choice.
