BEFORE / AFTER

Before & After · Real photo comparison

Shot on site in the same space — harsh glare before installation, soft and comfortable light after

Same Office · Two Window Treatments, Real Shots

Interior goes dark once the traditional blind is drawn; lights on in daytime — **Traditional blind:**Shading by blocking: drawn means darkness, daytime lights on, no view

ESEC curtain shades the sun while keeping the room bright; street view clearly visible — **ESEC curtain:**Equal shading and heat control, bright and open interior, street view and greenery clearly visible

Same window · half-lowered side-by-side comparison

Same window, same frame: the curtained upper half shades and insulates, while the bare lower half takes direct sunlight — **In one picture:**On the same pane of glass, the curtained upper half reflects heat with soft, diffused light, while the bare lower half lets in harsh direct sun — lower it for coolness, raise it for the view.

THERMAL PRINCIPLE

How It Works · Easy to understand at a glance

ESEC Insulating View-Through Shading Window Curtain: High Reflectance + High Clarity · Summer Heat Insulation, Winter Warmth

Summer · Reflects infrared heat

The high-reflectance functional layer returns 88% of solar heat outdoors, letting you raise the AC by 3℃ or even switch it off — interiors stay cool and comfortable.

Winter · Blocks heat loss

Blocks indoor heat from escaping through the glass, naturally raising room temperature by about 2℃ and lowering heating load — insulation you can see on your energy bill.

ESEC PRODUCT

ESEC Insulating View-Through ShadingWindow Curtain

A high-performance metallized functional fabric mounted outside the glass curtain wall — no changes to the existing curtain wall structure, delivering spectral-selective reflection for “Heat insulation, warmth retention, clear views, glare control” Four benefits in one.

88% total solar reflectance — only about 12% of solar energy enters the room
99.9% UV blocking protects occupant health and interior furnishings
96.5% NIR reflectance stops the main cause of indoor heat gain at the source
Lightweight and formaldehyde-free; no damage to the curtain wall structure, with a 15-year service life
Optional motorized control, compatible with building automation systems

SOLUTIONS

Widely suited toAll types of glass-envelope buildings

5.2 billion m² of existing glass curtain wall㎡,78% require energy-efficiency retrofits

Office Buildings / Corporate Headquarters

West-facing sun exposure makes glass curtain walls scorching and energy-hungry. ESEC window curtains significantly cut cooling load and peak electricity demand.

Hospital Buildings

Co-author of the Technical Standard for Energy Saving and Carbon Reduction Retrofit of Existing Hospital Buildings, delivering compliant energy retrofit solutions for hospitals.

Schools / Public Venues

Eliminates glare to protect eyesight while balancing daylight and shading for greater comfort in classrooms and spectator areas.

Industrial Plants / Parks

Insulates large skylights and curtain walls to improve shop-floor conditions and reduce annual energy spend.
