Thermal Insulation
Reduces heat transfer, helping to keep interiors warmer in winter and cooler in summer.
Insulated Glass
Double Pane Insulated Glass
Thompson Innovative Glass manufactures double pane insulated glass, engineered as an insulated double pane glass system with two panes separated by a spacer and a sealed air or gas-filled space. This double pane IGU improves energy efficiency and reduces heat transfer for modern building envelopes.
Double Glazed Insulated Glass
Double glazed insulated glass is one of the most widely specified glazing systems for new construction and window replacement projects, used across both residential and commercial buildings. In addition to its thermal performance, the sealed cavity also reduces outside noise transmission, making it a practical choice for homes and offices in urban or high-traffic areas.
Key Components
Glass Panes
Two sheets of glass, which can be clear, tinted, monolithic laminated or coated for specific properties (e.g., low-emissivity or reflective coatings to improve thermal performance).
Spacer
A warm edge frame that separates the panes and maintains a consistent gap. Modern spacers often require desiccants to absorb moisture and prevent condensation.
Sealed Space
The gap between the panes is sealed to create an insulating layer. This space is filled with air or an inert gas (Argon) which reduces heat transfer.
Seals
Durable sealants keep the space airtight and prevent gas leakage or moisture intrusion. Polyisobutylene (PIB) is the primary seal of the IGU, and structural silicone is the secondary seal that holds the unit together.
Key Benefits
Energy Efficiency
Lowers heating and cooling costs by minimizing heat loss or gain.
Frequently Asked Questions About Double Pane Insulated Glass
What is double pane insulated glass?
Double pane insulated glass consists of two panes of glass separated by a spacer and a sealed air or gas-filled space, forming an insulated double pane glass unit that improves energy efficiency and reduces heat transfer.
How does double pane glass work?
The space between the two panes traps air or gas, creating an insulating barrier that reduces heat loss in winter and heat gain in summer. This helps maintain indoor temperatures and improves energy efficiency.
What’s inside the space between the panes?
The space between the glass panes is filled with either air or an inert gas (such as argon or krypton) to enhance insulation. Gas-filled IGUs provide better thermal performance than air-filled ones.
Is double pane glass the same as Low-E glass?
No. Low-E (low-emissivity) glass is a coating applied to glass to reflect infrared heat while allowing visible light to pass through. However, many double pane windows include Low-E coatings to improve insulation and UV protection.
Can double pane glass be customized?
Yes! Thompson Innovative Glass has a variety of options including:
- Low-E coatings for UV and heat control
- Tinted or reflective glass for solar protection
- Laminated or tempered glass for safety and security
- Decorative or patterned glass for aesthetics
How much does double pane insulated glass cost?
The cost of double pane insulated glass varies based on size, glass type, coatings, and gas fill. Contact Thompson Innovative Glass for a custom quote.
