How Window Sealed Glass Is Made

If you’re exploring options for new windows, you’ve likely heard of sealed glass units, often called insulated glass units (IGUs). These are the modern standard for energy-efficient windows, and they play a crucial role in keeping your home comfortable year-round. At Ainger Windows & Doors, we specialize in installing windows in Barrie that use high-quality sealed glass. But how exactly is sealed glass made, and why does it matter for your home?

Let’s take a closer look at the process.

The Basics of Sealed Glass

Sealed glass units are made by combining two or more panes of glass, creating an insulating layer of air or gas between them. This design significantly improves energy efficiency by reducing heat transfer, which helps keep your home warm in winter and cool in summer.

Step-by-Step: How Sealed Glass Units Are Made

1️⃣ Glass Cutting and Cleaning

It all starts with cutting the glass to the exact dimensions needed for your window. The glass is then thoroughly cleaned to remove dust, oils, and any contaminants that could affect the seal’s performance.

2️⃣ Spacer Application

A spacer—a rigid frame that runs around the edges—separates the panes of glass. This spacer is typically made of metal or a thermally efficient material and holds the panes at a consistent distance. The spacer is often filled with a desiccant material to absorb moisture and prevent condensation inside the sealed unit.

3️⃣ Gas Filling (Optional for Enhanced Efficiency)

For high-performance windows, the space between the glass panes is filled with an inert gas like argon or krypton. These gases have lower thermal conductivity than air, helping to improve insulation and energy efficiency.

4️⃣ Sealing the Unit

The edges of the glass are sealed using a specialized sealant that bonds the glass panes to the spacer, creating an airtight barrier. This seal keeps moisture out and gas in, ensuring long-term performance.

5️⃣ Quality Testing

Before installation, sealed glass units are tested for durability, thermal performance, and air tightness. At Ainger Windows & Doors, we ensure that every sealed glass unit meets strict standards, so our windows in Barrie are built to last.

Why Sealed Glass Matters

Sealed glass units dramatically improve energy efficiency, reduce condensation, and enhance noise reduction. By investing in high-quality windows in Barrie, you’ll not only save on energy bills but also create a more comfortable, quieter living space.
