Introducing TOSTEM’s latest innovation: ATIS series

We would like to introduce our latest creation: ATIS series. 

More than just a window frame, we like to call this a work of art. Through the harmony of functional performance and
simple design, we allow you to fully experience ‘THE BEAUTY OF LIVING.’

Introducing our latest creation: ATIS

Through a long process of research and development, we have created a new series that is not only aesthetically pleasing but has patented innovation and technology built within. All ATIS products follow the same simple design concept: Seamlessly unites the inside of your home with the outside without taking anything away. We only add protection, privacy, simplicity, and ease of use. 

Streamline design

ATIS owns special innovations, pioneering in the aluminum door market.


The handle follows a circular motion, effortlessly reaching its horizontal position, aligning to the frame making it barely noticeable.

Specially designed for rooms where you want to keep outside eyes out but let the breeze in. You can open our high slit windows without having to reach up to the window height. We help you make the most out of every living area in your home.

High-performance, thin, and transparent lightweight fibers keep out mosquitoes and other bugs but let the air in without obstructing your view or feeling of openness.

Combining protection and preserving visibility and airflow, our INVISIBLE SHIELD INNOVATION is a light, airflow-conducive, and almost invisible material created by extensive R&D. Thin, light, and strong, it is the next generation of insect-protective screens. We continue to lead the way with best-in-class innovations for our products. 
  • 40% thinner: We use a 40% thinner wire than conventional insect screens So you get a 20% clearer view
  • 20% more airflow: With more airflow than conventional insect screens, INVISIBLE SHIELD lets more insect-free air flow through than any others
  • 20% less gap: We have shrunk the space for bugs to squeeze through by 20%, so not even the tiniest gnat can get in. 

Invisible shield innovation


The ATIS model combines 2 essential functions: Tilting and sliding in one, being the market pioneer to master the seemingly impossible. 

All-new: Tilt & Slide window

We continue to innovate and lead the category. Motion Made Easy – When sliding your window panel upward or downward, our patented PSS BALANCE HARDWARE supports and guides the movement. These windows bring beauty and ease of use to any house or apartment. Our unique design even takes care of light rain while ensuring steady airflow.

Not only considering the aesthetics and performance of the door but ATIS product system is also created to ensure maximum safety for all users. Our products have won the “KIDS DESIGN AWARD” award for our friendly, accident-proof designs for adults and children.

Barrier-free attachment

Our orbit-handle makes opening and closing windows safer. By placing the operation handle on the frame, there is no need to lean outwards. This safety enhancement was designed for smooth and light operation and eliminates the possibility of falling out of the window.

Our safety stopper is always there and always ready to stop mistakes from becoming accidents. Our patented design is built into all our windows to protect you and your family.
