 Our small pull down fly screen for windows works just like a traditional roller blind except that it fits directly onto your window frame instead of the recess. The retractable window fly screen then pulls down and clips into place at the bottom when the window is open allowing fresh air in whilst keeping insects out.

All our window fly screens are made-to-measure so there is no cutting involved. Once your fly screen arrives, all you need to do is click the four sides together and simply press the fly screen 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. Top Flyscreen 5 Star Review

    Posted by on 3rd Apr 2021

    Excellent easy to fit product supplied by a very efficient business

  2. looks good, works well 4 Star Review

    Posted by on 20th Aug 2020

    Wanted a fly screen to cover one of two opening windows in the same frame and the small fly screen was, and is, perfect
    With the window open and the screen down its great, and it even allows for the window to be locked in its "ajar" position if you're carefull when pulling the screen down. When the window is closed the screen doesn't pull past the handle
    Fits together extremely easily and is sized exactly as requested
    Cleaned the frame, and the double sided tape adhesive takes a strong grip
    I'd advise to fit to frame carefully as the tape feels like it could be pretty unforgiving if your alignment is slightly misjudged
    This product is really a 5 star unit, but gave it 4 stars because one side end is exposed (our choice) and the top and bottom corners do not have end caps which would give a better exposed finish. This is purely cosmetic and should not detract from a great product
    Glad we bought it, looks and is great, good value, would definitely recommend and will buy another if and when we need one

  3. They really are that simple to fit! 5 Star Review

    Posted by on 17th Jul 2020

    Having got sheep at the back of our house on occasions, we really needed screens to keep the flies out, and these do the job perfectly. Mounted on the inside of UPVC casement windows, they really are fly proof. If you are having them sitting above the window sill, make sure that you use packing under both ends whilst installing and not just in the middle otherwise the bottom rail will bow slightly and the seal will be compromised. And make a note of which adjuster does what before you put them up - it is very difficult to identify afterwards!

  5. Easy to assemble 5 Star Review

    Posted by on 27th Jun 2019

    The ordering process was extremely smooth with clear explanation about how to measure the window.
    We received the frame in just a couple of days and it took about 5 min to assemble and fit.
    We have been using it for few weeks now and it works perfectly, it is very stable and it blends with the window frame

  6. Great fly screens! 4 Star Review

    Posted by on 10th Apr 2019

    I have these on all the bedroom windows, easy to measure and fit. You can barely see them, but ideal when it’s warm to sleep with the windows wide open and keep all the insects out. I also have a pedigree indoor cat, so having these means I can have the windows open without the cat getting out. Definitely recommend these screens.

  7. Fly Screen 5 Star Review

    Posted by on 10th Jul 2018

    These screen are wonderful, I have been looking for Screens that are more inconspicuous as I didn’t want or need a fly screen outside of the summer months, these are the perfect solution as they roll back into the cassette.

    Ordering is very easy, so is measuring and a quick confirmation with diyflyscreens to double check the sizes I had my screens a few dats later.

    I’m now looking to screen other window. I couldn’t be happier.

  8. Simply Excellent Product 5 Star Review

    Posted by on 14th Jun 2017

    I back onto woodlands, so fly screens are essential and I've tried three types before which were a nightmare to fit, don't work smoothly and sometimes didn't work at all and opened on their own. BUT these are excellent! Took maybe 60 to 70 seconds to assemble and fit. They work very smoothly and in testament to it, I've recently ordered another 2 units and am thinking about replacing the ones that don't work properly.
    Also I should add the closing mechanism is very solid and can't see a risk of these opening accidentally.
