Product features:
Sunshade: The light transmission reduction coefficient is as low as 0.12, creating a comfortable and quiet indoor environment. The blinds are hollow and closed, and the angle adjustment and retraction are achieved through external or remote control.
Energy saving: The use of 5mn+19At5mm blinds reduces the energy loss of glass by 2/3. When the blinds are adjusted to the appropriate angle, the heat transfer coefficient of the glass is only 1.8W/2.K (the heat transfer coefficient of aluminum alloy doors and windows does not exceed 2.7W/2.K).
Sound insulation: Excellent sound insulation performance, noise reduction can reach 32bd, most suitable for office partitions and building doors and windows around roads.
Cleanliness: Neat and clean, no curtains are required, easy to clean and disinfect, and dust-free.
Safety: Reduce fire hazards, double-layer tempered glass improves the safety level of the overall building, has strong wind and impact resistance, and reduces the risk of breaking windows into the room on low floors.
Economic efficiency: Reduce air conditioning energy consumption and save electricity consumption in Dali.
Anti-ultraviolet: The ultraviolet penetration coefficient is 0.00/0.02, which protects indoor items and saves the purchase and cleaning costs of curtains.
