Our pull across fly screens for windows suit a variety of window types and are perfect for letting fresh air in and keeping pesky insects out. The retractable mesh can be simply pulled across when the window is open to keep unwanted visitors at bay.

All our DIY fly screens are made-to-measure so there is no cutting or sawing involved. Once your fly screen arrives, all you need to do is click the four sides together and then simply press it onto your existing window frame using the super-strong adhesive strips.

We know you’re going to love your new DIY fly screens and we are so confident in our easy-to-use measuring guides, we offer a no-quibble exchange. Find out more.

Suitable for: casement, tilt and turn, hopper and sash windows and roof vents.

Maximum effect:

  • No gaps: our cassette frame ensures there are no gaps around the edges where insects could potentially get in, unlike ineffective chains and curtains.
  • More durable: our roller tube holds the insect screen fabric in an enclosed housing keeping it clean and protecting it from the premature weathering and accidental damage common to fixed-mesh fly screens.
  • Always taut: our spring lock adjuster stops the fly screen from being over pulled so the mesh remains taut and ensures no insects can get through.
  • Smooth action: spring tension adjuster increases or decreases the recoil rate so that it retracts smoothly into the housing.
  • Discreet: manufactured in white uPVC to match your existing frames for a smart, discrete look. Mesh retracts out of sight when not in use.

Minimum effort:

  • No cutting: our fly screens are made to measure for you so there is no tricky cutting or sawing involved.
  • Easy assembly: our fly screens come in just four pieces which simply click together meaning you don't have to be a DIY expert to fit this product.
  • No screws: sticks to your existing frame using super strong foam tape so there's no drilling required and no permanent alterations to your frames.
  • Fit and forget: once fitted, your fly screen stays in place all year round so it’s always there when you need it.


DIY fly screens are also suitable for a variety of commercial applications including restaurants, canteens, cafés, snack bars, hotels, pubs, residential homes, schools, nurseries and home businesses. Visit our fly screens for business page for more information.

  1. Good Quality and sixing 4 Star Review

    Posted by on 18th Aug 2021

    Ordered online, received exactly what I ordered. Fits well. Only problem is the double sided stick tape fitting. I need the screw the side opposite the main cassette as it kept on coming unstuck. Easily done but fixing could be better. Overall I would still recommend it

  2. Excellent 5 Star Review

    Posted by on 1st Apr 2021

    Really pleased with product. Easy to put together and use. Arrived on time.Measurements are exact. I might have to take it down and refit as one side stuck down slightly bowed so there is a small gap when the screen is pulled across. This was my error as I was putting it up on my own.
    Will definitely be ordering more of these screens.

  4. Very Good Quality 5 Star Review

    Posted by on 23rd Sep 2020

    The product is a DIY version of Phantom Screens from the US. We have used them on 6 windows in the UK and had previously used them in Australia. They are the best. Virtually invisible when drawn and the retracting mechanism excellent. In our opinion the best on the market. Maybe not the cheapest but you get what you pay for.

  5. Great Quality & Fast Delivery 5 Star Review

    Posted by on 5th Aug 2019

    This is my third order (I started off with a flyscreen for my patio door, and was so pleased with it bought another for a second doorway). The window screen just purchased is equally good (uses the same size profiles as the door screens). The mesh used is excellent - there is virtually no visual impact when looking through the closed screen (from indoors to the outside). The double sided tape used to stick the screen to the window frame is very effective too. I was also pleased that the measurements I supplied when ordering were faithfully adhered to. Turnaround time was swift too. Less than a week from ordering to receiving the blinds.
