Window Fly Screen - Light Duty Framed (Made-to-Measure)

Print this page

Instructions below describe how to measure for both a standard casement and a traditional sliding sash window.

Use the drawings to give you the measurements for the width and height dimensions in the ‘get price’ tab:

• Width = measurement A
• Height = measurement B

Please ensure your measurements are entered in millimetres (mm),

Once you’ve placed your order we will contact you for measurements C, D, E & F before proceeding with the manufacture of your screen,

Please, also check your window carefully for any obstructions that need consideration when fitting your screen. These include….

• Trickle vent present on the flat framework around your opening.
• Locking wedge present on the flat framework where your handle locks the window shut.
• Rod and stay (A rod with holes in it and peg that enables you to keep the window open at certain position)
• Tiles that finish halfway up the reveal obstructing the flat framework

If any of the above are present, please let us know, as alternative dimensions may be required.

Standard Casement Window – side or top opener

Sash Window - fitted to full sash

Fitted Externally so the screen can be left in place without interfering with the opening and closing of the window or fitted internally

Sash Window - fitted to top or bottom sash

Fitted Internally to the lower or upper sash – Use the same principle for measuring either of the sashes

* The height of the screen can be the full height of the opening sash or the height to which you normally open your sash.

Depending on the style of your sash there may be a gap between frame D and the screen.  This can be filled with UPVC trim, batten, adhesive pile seal or similar. Let us know if you need advice.

Which mesh do I need ?

We offer two types of mesh with this screen. Your choice will depend on which insects you wish to keep out and the type of use. Both meshes are fully compliant with food safety regulations.

Standard insect mesh - 18 x 16 holes per square inch

Examples of insects this mesh will keep out:Bees & Wasps, Bluebottles, Cluster Flies, Crane Flies, Daddy-Long-Legs, House Flies, Hornets, Ladybirds, Mosquitoes, Moths, Butterflies and Spiders.Standard insect mesh is designed and manufactured to ensure maximum visibility (through the screen) ensuring as much light passes into the room as possible.

We recommend this mesh for all areas of the UK except in parts of Scotland where Midges are present and other parts of the UK where Corn Flies and Thunder Bugs/Thrips are present.

Midge mesh - 30 x 20 holes per square inch

This mesh will keep out:The same as Standard insect mesh + Midges, Corn Flies and Thunder Bugs/Thrips

Midge mesh has a tighter weave than Standard insect mesh to ensure Midges, Corn Flies and Thunder Bugs/Thrips cannot penetrate, however the visibility and airflow is reduced slightly.

We recommend this mesh in parts of Scotland where Midges are present and other parts of the UK where Corn Flies and Thunder Bugs/Thrips are present.Please note - genuine Midge mesh is 30 x 20 - anything less e.g. 20 x 20 or 18 x 16 will not keep midges out.

Stainless steel insect mesh - 18 x 14 holes per square inch

Examples of insects this mesh will keep out:

• Bees & Wasps, Bluebottles, Cluster Fies, Crane Flies, Daddy-Long-Legs, House Flies, Hornets, Ladybirds, Mosquitoes, Moths, Butterflies and Spiders.

Stainless steel insect mesh is highly durable and long lasting which makes it ideal for demanding commercial environments. This mesh is fully compliant with food safety regulations.

We recommend this mesh for screens in commercial kitchens, where regular screen cleaning is required and routine use may result in damage to a standard mesh.

Fixings

Lift on/off hinges with turn buttons

This fixing consists of a 2 part hinge, one part fixes to the edge of the screen and the other to your window frame. Both are screwed in position. The two hinge parts are connected with a pin which allows you to lift the screen off the hinge for cleaning or storage. The screen is held closed with turn buttons as shown in the second image below. The button is turned through 90 degrees to lock/release the screen.

Magnetic strips

No drilling or screwing required for this magnetic option. It consists of two, 13mm wide, self-adhesive strips with opposing magnetic polarity, one adheres to your window frame, the other adheres to the back of the screen.  They magnetise together to hold the screen in place.

Turn Buttons

The screen is held closed with 'turn buttons' screwed into your framework to the side of the screen. The button turns through 90 degrees to lock/release the screen.
