Magnetic Insect Screens

What is the screen made of?

Answer: The screen is made of durable and quality materials, that are hardly visible (aesthetics), that do not rust or shrink and are washable.

It comprises of:-

Flyscreen Mesh

The fly screen mesh is Phiferglass, standard 18 X 16 (thread count per square inch) mesh insect screening, and is woven from permanent glass yarn, coated with a protective vinyl to ensure lasting beauty, color and flexibility. It is produced under the most exacting conditions to meet extremely rigid specifications. Phiferglass is noncombustible and will not rust, corrode or stain. Dark Phiferglass screens offer the best outward visibility of the product line.

Flyscreen Frame

The frame is made from flexible (1/2 inch | 12.5mm wide) PVC strips that is very durable and has a professional finished appearance (vs cheaper “recycled” plastics with impurity that is brittle and matt)

Magnetised Strips

Long-lasting and made from a new-generation of permanent magnetic powder. The screen is held and secured together using a grooved magnetic stripe which interlocks into the window frame whilst securing the flyscreen mesh to the screen.

3m Adhesive

One of the magnetised strips (you get x2 – one that is attached to the frame – the second which is attached to your window frame) is equipped with a 3M adhesive tape for strong adhesion to your window.

This magnetic strip can adhere to any smooth surface including aluminium alloy, steel, wood, glass and others. Ideal for rental properties the magnetic strip attached to your window can tear off without leaving any sticky traces. The 3M adhesive tape is attached to your window frame to provide a substrate so that the magnetic wire mesh window frame can stick to the window.

Is it easy to install?

Yes, it is.

There is no need for any tradesman equipment or tools. Every boxed set of magnetic insect screens comes with detailed instructions (including video instructions) that you can easily follow.

It should take about 15-20mins to set up each screen.

First timers may take a little longer to measure, cut, assemble the flyscreen and then install onto the frame. But rest assured that with some practice and confidence, following installations will take much less time to complete.

We do recommend you spend considerable time ensuring your existing window (frame area) is free of dust & oil. This will ensure that the magnetic strip secures to your window frame well which will in turn keep the flyscreen firmly attached.

For ease of setup, use a good and clear working floor space where you can easily lay down the flyscreen frame as you do the set up.

Can your magnetic insect screens be adapted for triangular and rhomboid windows?

YES – you can carefully cut the frame to any degree you would like

The screens come with x4 standard 90 degree corner pieces (see attached photo)

These corner pieces are not functional at all with respect to the structural integrity of the screen … but merely act as an aesthetic piece to give a clean finish to the corners (and allow for a finger pull mechanism).

Do you provide an installation service?

The DIY kit for our screens is extremely easy-to-install, you can find the installation video here.

With that said we do understand that some people prefer to engage hassle-free installation service. 

We recommend a great online service called Airtasker. Simply order your screens online here and when they arrive co-ordinate a local handyman from Airtasker to come and fit them for you.

Is the size of the screens fixed? I only see a number of sizes on your website

No – our magnetic insect screens can be easily customized (ie cut to fit any window size)– at the time of installation.

The custom fitting of the screen to your specific window is done when installing by cutting the PVC frame to a size to fit your window.

We recommend you buy a one of the screen sizes slightly larger than the window you wish to install it on – so you can cut the frame to size.

To help you save money & to minimize waste, we provide x3 standard sizes that you can buy – which match closely average window sizes across the globe.

Will it fit my window?

Answer: YES…. These screens can be fitted on any window frame.

It is suitable for most window types: sliding, push-out casement, louvres.

The screen affixes to your window frame using a strong 3M adhesive. This adhesive can attach to all types of surfaces, including: aluminum alloy, PVC, plastic, wood, steel etc

How do I measure me window so I know the size of flyscreen is best for my window?

For the detailed way of taking measurements, see the photo & detailed method on our product page here.

The idea is that you measure your existing window using the method shown and then choose the next closest size to buy. For example, if your window size is 112cm x 95cm, choose 120cm x 100cm (= model 1210).

What colour is the flyscreen mesh?

Answer: Whilst the screen mesh is a dark colour, the screen is completely see through.

Will the magnetic strip be effective over long periods time?

The ferromagnetic rubber magnet will not lose its magnetism and shape under normal home use conditions.

Our magnets are manufactured to world class quality. The adhesives used to stick the ferromagnetic rubber magnet to the window frame is from a the leading 3M company.

How long will the screen last?

Our screens are manufactured to last for more than 10 years under normal use. The 3m magnetic strips are guaranteed for life.

If for any reasons any of the other parts faulter (eg. mesh is torn), you can easily buy a replacement part from us without having to fully replace the window screen.

We have readily available accessories for all of our screens which allow you to make minor repairs easily when/if required.

Will ventilation of brightness of my house be affected by the screens?

No it will not

The grey/charcoal colored window mesh appears invisible from any distance further than a few feet.

This is the primary reason we do not make the mesh out of other colours (example: white, green).

If you allow the window mesh to become very dusty (after a few months of use), you will see a film of on it.

To return it back to its original (new looking) condition – simply remove the screen and wash it (see how to wash your screen tip in this set of FAQ’s)

For ventilation of your space, normal airflow is not affected by the newly installed screens and air will be able to move freely in and out of your house.

In fact, this is the one of the main reasons why our customers install our screens: in an effort to keep the windows open (allowing airflow) while keeping the mosquitoes, lizards, flying cockroaches and other creepy crawlies out.

Can I make multiple screens from x1 big screen?

Answer: Check the sizings of your smaller windows. The general answer is yes (but you have to request more corner pieces from us  – which we are happy to provide)

Do you sell accessories?
Yes we do. If you need accessories for your screen (like extra corner pieces, joiners, extra mesh etc etc, you can buy these separately.
How do I clean the screen?

Cleaning is very easy and simple.

It is an idea to wash your new window screen once every 1-2 months or even more if you find the mesh is dusty..

The way to clean your screen is by placing your screen against the wall or even hang it on a clothesline, and simply hose it down with water.

Alternatively, you can use a soft sponge or cloth, with some gentle detergent.

After washing simply let the screen drip dry.

General cleaning of your Magnetic Window screen will not affect the magnetism.

Some of our customers also like to quickly vacuum the screen while it is still on the window. This works well also!

What is the wind clip / holding clip installed on the window screen for?

Every screen we supply comes complete with a set of wind/holding clips.

They should be set up at the upper one-third of the installed screen.

The function of the wind holding clips is to securely hold the screen in place when you are lifting the screen open from the bottom to access your window.

Can the screen be magnetically attached to a metal car frame (like van rear doors) without gluing any magnetic strips to car?

Answer: If the metal is one of the magnet attractable metals, then yes. Magnet attractable metals are: Iron, cobalt, nickel and their alloys, ferrite, etc. Most car frames can be attracted by magnet, thus you don’t need to glue magnetic strip to your car.

Can I use the window screen to keep my cat safe at home?

Yes you can!

In fact many of our customers install these screens to keep their cats safe.

For this purpose, they only install the mesh on those windows where their cats like to look at. This is a very cost effective way of using our window mesh.

Our customers who adopted their cats from the various shelters confirm that our window screen mesh is accepted by their fosterers.

Our screens are ideal for those owners who need to keep their cat safe in highrise buildings & condo’s.

A few more things you should know about window insect fly screens


Is the insect mesh fire retardant?

YES… watch the following quick video demonstration. 

Will a fly screen block out any natural air, light or your view of the outdoors?

Fly screens are like shields for protecting your home from fly or pest invasions. Installing fly screens may to some extent obstruct light and air as well, but the type of mesh you install is available in a wide variety of forms to best suit your needs.

To boot, fly screens come available in both foldable and fixed forms which will give you some extra flexibility.

Will a fly screen ruin the view of my open space?

As fly screens come in many different forms and sizes, one will always have the freedom to choose an option which best suits their needs for their particular living space.

You will be able to choose from among different types of fly screens like hinged screen, sliding screen, retractable screens, and even motorized screens: whatever best complements your home as well as your wallet.

How expensive are fly screens?

Because the materials used for fly screens usually include aluminum and mesh of high quality, there will certainly be some cost associated with it.

But installing fly screens, fortunately, can be a one-time investment (if you make sure to choose the right ones and not cheap-out too much), and the benefits of keeping flies and pests out of your home forever will more than make up for the cost.

What if I only need fly screens for certain seasons?

If being able to remove your fly screens is important for you, there are a variety of different types of fly screens which can be easily displaced if not removed entirely, such as sliding screens or magnetic screens, allowing you to keep your windows open completely during certain seasons or at certain times of the day.

How about cleaning your fly screens?

Most fly screens are very easy to clean using the hose of your vacuum cleaner.

Fly screens will eventually build up quite a lot of dust so it is best to do this regularly.

If you have any questions about which fly screens would be best for your home, don’t hesitate to contact us.

Are fly screens any better than other insect repellents?

As the name implies, fly screens serve to screen your windows from unwanted guests like flies or mosquitoes.

Given the number of health issues associated with mosquitoes and other pests, fly screens offer a very simple yet powerful solution to a variety of airborne hazards to your family’s health.

Moreover unlike other means of insect and pest removal fly screens are a permanent solution and one-time purchase only.

Opting for other solutions such as fumigation are not only more expensive than screens but also pose health risks of their own, as the smoke and chemicals used for such solutions tend to cling to the interior of your home long after the process has been completed: allergies or lung sensitivities can be triggered even after all of the smoke has cleared, so to speak.

Especially if your home or business is in an environment prone to breeding insects all year round, then you are at risk of being exposed to a number of diseases or flues from these flying rascals.

The cleanliness of your home or workspace, without window screens, would also be compromised due to the tendency of keeping the windows closed to keep out bugs, in turn compromising your ventilation.

Accordingly, the safest and most convenient option for keeping out pests is fly screens, to keep them out altogether, and once the process is done, it’s done: no more maintenance (barring occasional cleaning) or purchases required.

If you are still unsure about which type of fly screen is best for your home or workplace, please do not hesitate to contact us.
