Double handle built-in blinds feature a low light transmission reduction coefficient of 0.12, providing a comfortable and quiet indoor environment. The hollow, airtight blinds can be easily adjusted or retracted using either external or remote control.

Energy Efficiency
Reduce energy loss by up to 2/3. Standard buildings lose around 50% of energy through doors and windows, with 75% lost through glass. With double-glazed blinds, the heat transfer coefficient can drop to just 2.0 W/m²·K, reducing air conditioning energy consumption and lowering electricity costs.

Sound Insulation
Excellent noise reduction up to 32 dB, making it ideal for office partitions, residential windows or buildings near busy streets.

Hygiene & Cleanliness
Blinds are fully enclosed within the insulating glass, eliminating the need for curtains. Easy to clean, dust-free and hygienic.

Safety & Durability
Double-layer tempered glass enhances wind and impact resistance, reducing breakage risk and improving overall safety.
