Tempered Insulated Glass

Description:
Insulated glass is made of two or more glass panes separated by a spacer and sealed to form a single unit with an air or gas-filled cavity. It enhances thermal insulation, reduces condensation, and improves energy efficiency.
Applications:
Ideal for exterior windows and curtain walls in residential and commercial buildings.

PRODUCT DESCRIPTION

Insulated Glass (IGU) Definition

Insulated Glass Units (IGUs) are made of two or more glass panes separated by an aluminum spacer and sealed with air or inert gas (argon, krypton) inside. It reduces heat transfer and improves acoustic and thermal performance.

Key Features

Energy efficiency (thermal insulation)

Reduced noise transmission

Prevents condensation

Enhanced comfort in buildings

Applications

Office and residential windows

Glass curtain walls and facades

Skylights and roof glazing

Display windows and soundproof rooms

Subtypes

Tempered insulated glass

Laminated insulated glass

Low-E insulated glass

Gas-filled IGUs (argon, krypton)

Triple-glazed insulated units

Printed or silk-screen IGUs

Parameter class	Parameter Name	Standard Values	Description
Thermal Performance	U-value (W/m²·K)	Standard Double Glazing: 2.8~3.2 Low-E Double Glazing: 1.6~2.0 Argon Filling: ↓0.1~0.3	Lower values indicate better thermal insulation
	SHGC (Solar Heat Gain Coefficient)	Clear Glass: 0.7~0.8 Low-E Glass: 0.25~0.40	Lower values reduce solar heat gain
	VLT (Visible Light Transmittance)	Clear Glass: 85%~90% Low-E Glass: 70%~80% Frosted Glass: 50%~60%	Affects indoor lighting brightness
	VLR (Visible Light Reflectance)	Clear Glass: 8%~12% Low-E Glass: 15%~25%	Higher reflectance reduces glare
Acoustic Performance	Rw (Weighted Sound Reduction Index, dB)	6mm Single Glass: 31 6+12+6 Double Glazing: 34 10+12+6 Double Glazing: 36 6+12+6.5 Laminated Glass: 38	The higher the value, the stronger the sound insulation effect
Structural Parameters	Glass Thickness Combinations (mm)	4+4, 5+5, 6+6, 10+6, 6+6.5 (laminated)	Optimize sound insulation/load-bearing
	Spacer Material	Aluminum (high thermal conductivity) TPS Thermoplastic (warm edge) Stainless Steel (corrosion-resistant)	Warm edge spacers ↓U-value by 0.1~0.2
	Spacer Width (mm)	6, 8, 10, 12, 14, 16, 18, 20 (2mm increments)	Wider spacers ↑ insulation but ↑ weight
	Gas Filling	Air (standard) Argon (recommended, ↑U-value by 10%~15%) Krypton (premium, ↑U-value by 15%~20%)	Inert gases reduce thermal convection
Glass Types	Basic Types	Clear Float, Low-Iron, Tinted (Gray/Blue/Green), Frosted, Patterned	Light transmittance of low iron glass ↑5%~10%
	Functional Glass	Hard-coated Low-E (U-value 1.8~2.2)	Soft coating requires inner layer protection
		Soft-coated Low-E (U-value 1.6~1.8, requires inner protection)
		Laminated Glass (anti-breakage/sound insulation)
Dimensions	Min. Size	300×300 mm	Most sizes customizable
Dimensions	Max. Size	3300×13000 mm	Most sizes customizable
Sealing Process	Primary	Butyl Sealant	Gas leakage prevention (bonds spacers)
	Secondary	Polysulfide (aging-resistant)	Silicone is suitable for high temperature areas
		Silicone (high-temperature areas)
		Polyurethane (high strength)
Edge Design	Warm Edge Spacers	U-value Reduction vs. Aluminum↓0.1~0.2	Recommended For High humidity areas
Edge Design	Warm Edge Spacers	Condensation Risk30%~50%	Recommended For High humidity areas
