Why do you need the Koguryeo Systems Flyscreen?



Here is the list of frequently asked questions and answers about the Koguryeo Systems products.

How much is it?

Because our products are not ready-made, the price is not fixed.
Expect KRW 350,000 – 400,000 for a big living room window and KRW 300,000 – 350,000 for a small window.

Why are your products expensive?

To begin with, our products are completely different from other flyscreens, from materials to manufacturing method.
Our products do not just keep bugs away; they are designed for safety purposes as well. Though our flyscreens may seem expensive in the beginning, they will be well worth it because they can be used permanently.

Does the mesh tear or develop rust?

We use 100% stainless steel for mesh. Our flyscreens are much thicker and stronger than regular flyscreens. It would be a challenge to tear or damage the mesh. Our products do not also develop rust.

How are security window and security mesh different?

Security windows are not very appealing to look at as they remind you of prison. Moreover, once the bars are cut off at different points, it is very easy to make a space for intrusion (but it has an advantage as well, that they are visually effective).
On the other hand, security mesh works as flyscreen but also buys you time by keeping criminals at bay.
You will not need to replace the old flyscreen to install our products. Use our products permanently with peace of mind.

What kind of locks do you provide?

We provide the double crescent and rotating number key.

Does your safety mesh really keep you safe?

Of course there is no 100% guarantee for safety in this world. We wish there were.
We assume that you keep your doors securely locked when you are out of home. But when you’re home and someone is trying to get into your house, our products will buy you time and keep you further away from harm’s way.
