Nabsystem strives for creative and future creation through research and development activities in various architectural fields. Through the value analysis of R&D projects, we want to increase customer confidence and satisfaction with a reasonable and feasible design. Creating a window that's creative and user-story, not just making it, is an important element of the Nabsystem. Furthermore, the result of integrating elements that emphasize window identity and innovation creates new future value for users.


Nabsystem has secured about 22 original technology patents for sliding system windows, and currently applied for about 20 patents.
We will continue to secure intellectual property through continuous research and development to further enhance our value as a technology company.

“Save 87.29%
compared to comparable products for economic efficiency”

  • - Single windows are similar or cheaper than conventional sliding double windows (However, the double window will increase by around 10 percent.)
  • - Price is equivalent for glass combinations

Application effectiveness analysis

Comparative analysis of fine dust inflow

[Variation of fine dust concentration by time according to internal and external pressure differences]

(As of February 26, 2014 at 08 a.m.)

In the general window, all indoor air is replaced with contaminated air outside in about 1 hour and 20 minutes.
