Fresh air in — flying pests out. Custom made in the UK.

Our System 41 roller fly screen for windows is hand-built to your exact measurements in our UK factory. A slimline 41mm spring-loaded cassette sits discreetly at the top of your window frame — mesh tucked away when not needed, protected from UV and dirt. Four mesh types available — standard insect, midge, pollen or pet-resistant — all in the same cassette, in white, brown or anthracite grey.

Enjoy Fresh Air — This and Every Summer

Open windows invite flying pests. Install our roller fly screen for windows and enjoy fresh air this and every summer — without flies, wasps, spiders or other insects finding their way in.

Discreet Hideaway Protection

Deploy the screen using the colour-coded handles — the mesh runs between 30×22mm side guide rails and pulls closed to the sill. No sill? An L-shaped closing profile is supplied. When insects aren't a problem, the mesh retracts smoothly into the cassette. No storage, no seasonal removal.

Built-In Braking System — Safe, Smooth Retraction

Without a brake, a spring-loaded screen snaps back hard when released — startling, potentially dangerous, and damaging to the mesh over time. Our System 41 includes an internal braking mechanism on all screens over 450mm wide, giving smooth, quiet retraction every time. Included as standard — not an optional extra.

Four Mesh Types Available

  • Standard Fly Screen — standard gauge fibreglass; blocks flies, wasps, spiders, bees and most insects
  • Midge Mesh — extra-tight 20×30 weave for Scotland and midge-prone areas
  • Pollen Mesh — finest weave, designed for hay fever and allergy sufferers
  • Pet Resistant Mesh — same insect protection, heavier claw-resistant gauge

Available for Windows, Single and Double Doors

Easy to Measure, Install and Operate

Download our Measuring Guide (PDF) and Installation Guide (PDF) before your order arrives. A drill and screwdriver is all you need — most customers are done in under an hour. Pull the bar down to deploy, tilt to retract.

Frequently Asked Questions

Everything you need to know about our roller fly screen for windows.

Do retractable fly screens work?

Retractable insect screens are compatible with big and small apertures, ranging from windows and single doors to french doors and bi-fold doors. 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.

How easy is it to install a roller window fly screen from NewBlinds.co.uk?

It's surprisingly straightforward to install a roller window fly screen from NewBlinds.co.uk. It’s a simple case of screw fixing the bracket into which the cassette is clipped, and also screw fixing the two side channels. Each product comes with a user-friendly instructions guide that details step-by-step procedures on how to correctly fit your fly screen. Moreover, if you encounter any problems during installation, our customer service team is always ready to offer assistance.

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.

What is the installation process for a door screen?

The installation process for a door screen from NewBlinds.co.uk is straightforward and user-friendly. Each of our door screens comes with a detailed step-by-step installation guide, and no professional experience is needed.

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.

Roller Fly Screen for Windows and Child Safety

Child Safe By Design - Handle on Bottom Bar: Roller Fly Screens for Windows can be operated using a discrete handle on the bottom rail. We call this ‘child safe by design’ as there are no looped cords or chains to operate the blind.

About Child Safety
At newblinds.co.uk, child safety is of paramount importance. If left hanging freely, chains and cords from blinds can pose a direct threat to children. For this reason, we are working towards all of our products being cordless or chain-free and therefore “safe by design”.

Where it is not yet feasible to supply a product that is “safe by design”, we ensure that the product is fully compliant with Child Safety legislation. Not only do we ensure that, where necessary, our products are supplied/fitted with child safety cleats/devices, but we also
supply, free of charge, these items to our previous customers.

Click the link above to inform us of your requirements. To learn more about the BBSA ‘Make it Safe’ campaign and blind cord safety, you can watch the video below.
