Double-Silver Coated Glass

Product Introduction

Double-Silver Coated Glass is a high-performance Low-E (low-emissivity) glass designed to deliver superior thermal insulation and solar control. It features two layers of silver in a multi-layer metal oxide coating, applied using a magnetron sputtering vacuum deposition process. This advanced coating structure offers improved energy efficiency, excellent visible light transmittance, and reduced solar heat gain. It is ideal for energy-efficient residential and commercial buildings requiring both comfort and clarity.

Product Features

Dual Silver Layers: Two silver coatings enhance infrared reflection and minimize heat transfer.

Low Emissivity: Reduces heat loss in winter and heat gain in summer, improving thermal comfort year-round.

High Light Transmission: Allows abundant natural daylight, reducing the need for artificial lighting.

Solar Control: Significantly lowers solar heat gain to reduce cooling loads in warm climates.

Neutral Aesthetics: Provides a clear, modern appearance with minimal reflectivity or tint.

FAQ

Q1: How is double-silver glass different from single-silver coated glass?

A: Double-silver glass has two silver layers, providing better thermal insulation and solar control than single-silver glass. It is more efficient in both hot and cold climates.

Q2: Can this glass be used in insulated glass units (IGUs)?

A: Yes. Double-silver coated glass is typically used inside IGUs for maximum thermal and acoustic performance.

Q3: Is it suitable for high-rise buildings?

A: Absolutely. Its strong solar control and low reflectivity make it ideal for commercial facades and skyscrapers.

Q4: Where is the silver coating applied?

A: The coating is applied to an internal surface (usually surface #2 or #3 in an IGU) to protect it from weather and physical damage.

Q5: Does double-silver glass affect visibility or color?

A: No. It maintains a natural, neutral tone and clear visibility while blocking unwanted heat and UV rays.
