Offline Low-E Glass

Product Description

‌Offline Low-E glass‌ is a functional glass product manufactured through ‌vacuum magnetron sputtering‌, where multiple layers of metallic or compound coatings (including silver layers) are deposited onto the glass surface. Its core characteristics include:‌High visible light transmittance,and exceptional reflectivity for mid- to far-infrared radiation,delivering dual advantages of ‌thermal insulation‌ and ‌daylighting‌.

Colors

Standard color options include blue, green, and gray, with customization available for neutral tones, gold (rose gold), and other special colors.

Thickness

 3mm-19mm.

Size

3300*2134/2250/2440mm, 3660*1900/2134/2250/2440mm 1650*2440,1830*2440 etc. 

Application

•‌Architectural applications:Widely used in high-end curtain walls and residential windows, balancing aesthetics with energy efficiency.

‌•‌Commercial spaces:Ideal for soundproofing and thermal insulation in business environments, such as office buildings and hotels.

•‌Specialized applications:Double-silver or triple-silver glass is recommended for green buildings with stringent energy requirements or extreme climate regions.


Product details
Benefits

1.By reflecting far-infrared radiation through the silver layer, it reduces indoor heat loss in winter and blocks external heat in summer, achieving significant energy-saving effects.

2.The light transmittance is adjustable, supporting varying shading coefficients (Sc 0.2–0.7) to meet diverse lighting requirements.

3.It can reduce noise by approximately 30 decibels, with enhanced performance when combined with inert gas filling.

4.Reduces building energy consumption, Lowers fuel usage, and minimizes harmful gas emissions.

5.Single-silver (5-layer coating), double-silver (9-layer coating), and triple-silver (13+ layer coating)—more silver layers result in stronger thermal insulation.

6.The silver layer is prone to oxidation and abrasion; it must be processed into insulating glass units (IGUs) and requires protective measures during transportation.
