Architectural Insulated Glass Overview

What Is It?

Architectural Insulated Glass is a special glass that keeps buildings comfy and saves energy. You see it a lot in curtain walls, windows, and doors. This glass has two or more glass layers with space in between. The space is filled with air or gases like argon or krypton. These gases help stop heat from moving in or out. Rooms stay warmer in winter and cooler in summer.

HN Central Glass makes insulated glass units with double or triple glazing. You can pick the thickness you need for your project. The glass uses special gas fills and strong spacer bars. These things help you use less energy and make buildings quieter. The glass has a low U-value, so not much heat gets through. This means you feel more comfortable and pay less for energy.

Tip: Insulated glass units with low-E coatings keep out extra heat from the sun but still let in sunlight.

Here is a table that shows the main parts and ways used in architectural insulated glass for curtain walls:

Component/Method	Description
Types of Glass	Float glass is common. It is 1/4 inch thick for spandrel areas and 1 inch thick for insulating glass.
Insulating Glass Units (IGUs)	Usually made of two 1/4-inch glass layers with a 1/2 inch airspace, often filled with inert gases.
Curtain Wall Classifications	Stick built and unitized systems. Unitized systems are put together before they get to the building. Stick systems are built one piece at a time on-site.
Installation Methods	Unitized systems use cranes. Stick systems use vertical mullions and glass panels connected at the building.

Curtain Wall Applications

You see architectural insulated glass in many buildings. Curtain walls use this glass to cover big spaces and make modern looks. Here are some places where you find it:

• Office buildings use big glass walls for sunlight and to save on electricity.

• Hotels and resorts have tall windows for nice views and privacy.

• Shopping centers and stores use glass fronts to bring in shoppers and keep inside temps steady.

• Cultural and public buildings use cool glass designs to control light and look pretty.

Architectural Insulated Glass helps you make spaces that look nice and feel good. You get better energy savings, less noise, and more ways to design your building.

Comfort Benefits

Thermal Insulation

You want your building to stay warm in winter and cool in summer. Architectural Insulated Glass helps you do this by stopping heat from moving in or out. The glass uses special layers and gases like argon or krypton. These features keep your rooms comfortable all year.

Look at the table below. It shows how much heat passes through different types of glass. The lower the U-value, the better the glass keeps heat inside.

Glass Type	U-value (W/m²K)
Single Glazing	5.8
Standard IGUs	2.8
High-performance IGUs	1.1

You can see that high-performance insulated glass units (IGUs) work much better than single glazing. You can save up to 50% on heating and cooling costs when you use IGUs instead of single-pane glass.

• Double and triple glazing make your curtain walls stronger against heat loss.

• Low-E coatings reflect heat back into your room, so you stay warmer in winter.

• Solar-control glazing helps block extra heat from the sun, keeping your space cooler in summer.

Tip: If you choose insulated glass with a dual-seal design, you get even better gas retention and long-lasting comfort.

Sound Reduction

You want peace and quiet inside your building, even if you live in a busy city. Insulated glass helps block outside noise so you can relax or work without distractions.

The sound transmission class (STC) rating tells you how well glass stops sound. A single piece of glass has an STC rating of 31. If you use two pieces, the rating goes up to 36. Laminated glass can reach ratings of 40 or more. This means you hear much less noise from traffic, people, or construction.

Curtain wall systems with high-performance glass use advanced materials to reduce noise. These systems are important in cities where noise pollution is high. You get a quieter and more comfortable space.

• Insulated glass units with special sound insulation properties help you enjoy a peaceful environment.

• You can choose glass thickness and adhesive types to improve noise reduction.

Note: If you use Architectural Insulated Glass in your curtain walls, you get both thermal comfort and sound protection. This makes your building a better place to live or work.

Efficiency Benefits

Energy Savings

Insulated glass in curtain walls helps you save money. It keeps heat inside in winter. It blocks heat from coming in during summer. Your heating and cooling systems do not work as hard.

• If you switch from regular glass to insulated glass, you can cut energy costs by about 23%.

• Upgrading to high-efficiency framing and glazing can save about $18,500 each year for a medium commercial building.

Argon and krypton gas fills help you save more. These gases are heavier than air. They slow down how fast heat moves through the glass. Using argon or krypton between glass panes gives better insulation. This means you pay less for heating and cooling.

Tip: Pick insulated glass with noble gas fills to save energy faster.

Sustainability

Insulated glass helps the planet when used in curtain walls. It supports green building rules and helps you earn points for LEED or BREEAM. Here is how it makes your building greener:

1. Stops heat from coming in or going out.

2. Makes the building envelope better for energy rules.

3. Cuts down on HVAC use, helping you get LEED credits.

Contribution to LEED Points	Description
Increase daylight exposure	Makes indoor spaces brighter and healthier.
Boost occupant comfort	Lowers glare and keeps rooms comfortable.
Improve energy savings	Reduces the need for extra lighting.

Insulated glass lasts a long time. You do not need to change it often. If you add insulated glass to old windows, you use fewer new materials and make less waste. This fits green building goals.

Certifications are important when you choose glass. Look for these certifications:

Certification Program	Description
ALI/AAMA Sealed Insulating Glass Certification Program	Checks how well the glass works and lasts.
IGMAC Certification Program	Tests and controls quality to keep high standards.
SGCC Certification	Makes sure glass is safe and does not break easily.

You can trust Architectural Insulated Glass with these certifications. You get energy savings and feel safe.

Key Features & Technologies

Low-E Coatings

You can boost the performance of your curtain wall by choosing the right Low-E coating. Low-E stands for "low emissivity." This means the glass reflects heat but lets in light. You get better comfort and lower energy bills. There are several types of Low-E glass. Each type has special features for different needs.

Type of Low-E Glass	Description	Key Features
Hard Coat Low-E Glass	Coating added during manufacturing	Scratch-resistant, good for tough environments
Soft Coat Low-E Glass	Coating added in a vacuum after production	Reflects more heat, offers better insulation
Smart Glass	Adjusts heat and light transmission	Changes with sunlight, improves comfort
Solar Glass	Combines Low-E with solar technology	Makes energy, adds extra insulation

You can pick the type that fits your project. For example, smart glass works well if you want to control sunlight. Solar glass helps if you want to save even more energy.

Tip: Low-E coatings help you keep rooms bright without extra heat.

Spacer Systems

The spacer sits between the glass layers in Architectural Insulated Glass. It keeps the panes apart and seals the edges. The right spacer system makes your glass last longer and work better.

• Warm edge spacers cut down on heat loss and stop condensation. They keep your building cozy and dry.

• Foam spacers give top insulation. They block heat and noise. They also flex, so your glass stays sealed for years.

• Metal spacers, like stainless steel, work well in tough weather. They are strong and last a long time.

You can expect insulated glass with advanced spacers to last about 25 years. In curtain wall systems, the glass can last over 60 years. Builders often add weep holes to frames. These holes drain water and help the glass last even longer.

Note: Choosing the right spacer system means you get better energy savings and a longer-lasting curtain wall.
