Challenges & solutions
Customer challenges & requirements
"Our ballroom has large glass walls. We used one-way film before, but at night with the lights on, people outside could still see in. We wanted an option we could press for real privacy, both day and night."
— Banquet Team · Sirathana Engineering
- One-way film doesn't block the view at night
- With old one-way film, brighter interior lighting at night let people outside clearly see in.
- The large glass wall lacked privacy
- The ballroom's large open glass wall left guests and events visible from outside at all times.
- Sunlit glass made the room hot and glaring
- The full glass wall faces the sun and the city view, making the room hot with glare disrupting the event atmosphere.
- Welcoming VIP guests requires privacy
- Events welcoming VIP guests need privacy that can be controlled at any moment.
The solution we proposed for this project
Press opaque at night to block the view from outside
When interior lights are bright at night, press opaque and the glass wall frosts, so outsiders can't see through.
Turn a large glass wall private
Press opaque and the whole ballroom wall frosts instantly, so the event stays private with no view from outside.
Block IR/UV to cut heat on the ballroom glass
InHouse smart film blocks 99.99% IR/UV to cut heat and protect furniture from fading.
Control privacy throughout every event
Switch clear-to-opaque to the rhythm of the event — clear to enjoy the view, or opaque when welcoming VIP guests.
Press clear to reveal the garden and city at dusk
Clear mode reveals the green garden and the city skyline, adding a luxurious touch to the banquet tables.
Switch the ballroom clear-to-opaque instantly
Switch clear-to-opaque in 0.1 seconds via remote or switch, controlling the whole ballroom glass wall.
Results after installation

Review from a real customer"After installation I'm really impressed. At night with the lights on for an event, one press to opaque and people outside can't see in at all; press clear and the garden and city view are beautiful. Every guest at the event admires it. The room clearly looks more luxurious and private."
