Ventilation Slots

Want to enjoy a good breeze without sacrificing home security? TOSTEM India's Ventilation Slots are the solution you need. Rather than being open like a typical window, the Ventilation Slots allow controlled airflow into a room for that cooler indoor temperature while filtering out dirt. With fully integrated insect screens, you can enjoy airflow without the nuisance of bugs, while maintaining an appealing appearance and compatibility with our existing aluminium windows. After years of outdoor exposure, the Ventilation Slots have still maintained their appearance and functionality.

Frequently Asked Questions

What is the difference between a regular window and one with a ventilation slot?

A ventilation slot can be referred to as a window with a small and more controlled opening for ventilation. With TOSTEM INDIA’s high-quality narrow mesh area and rubber gaskets, you also keep insects, dust, and noise at a minimum.

Will installing a ventilation slot mess with the aesthetics of the room?

Not at all! TOSTEM INDIA integrates the slot carefully into the window frame, ensuring that nothing disrupts that modern appearance. You still enjoy large glass panes and slim sightlines, ensuring a clean and stylish look in any room.

Is it possible to add a ventilation slot to an existing aluminium window?

It depends on your current frame’s design. In many cases, it is always easier to purchase a pre-engineered window. TOSTEM India ensures to offer you an easy way when it comes to installation with our “Window in a box” feature so that the process can become completely hassle free!

Is the ventilation slot hard to clean?

Not really. The mesh or screen can usually be taken out for washing, and the coated aluminium surface is easy to wipe down. This design makes it simple to keep the slot clear of trapped dirt, ensuring better airflow over time.

Does the ventilation slot offer sound insulation?

Yes. The rubber gaskets and perfect mesh helps reduce noise infiltration. Although it won’t match the quietness of a window that is fully closed, you still enjoy a more peaceful environment than you would if the entire window were open.
