- Our glass meets exceptionally high fire ratings. Our insulated glass units (IGU) are sealed units made from wire-free, transparent ceramic glass. A secondary pane of glass is used to complete the customer’s specification.
IGUs can be fire rated for up to 90 minutes in walls and doors, and up to 180 minutes in temp-rise doors. They pass the related positive pressure tests and hose stream tests. Ceramic glass can withstand temperatures up to 1,292 °F
Systems are typically 1" thick overall, but the thickness can vary according to the customer’s requirements for the secondary pane of glass.
Optional secondary panes include:
- Bulletproof Glass
- X-Ray Lead Glass (for medical imaging facilities)
- One-Way Mirror Pane (enabling single-sided privacy)
- Frosted Glass ( two-way privacy)
- Clear Tempered Glass
- Multiple Additional Options

Low E-Glass IGUs
Today’s business owners and facilities managers are determined not to spend too much money when it comes to maintaining their buildings at a comfortable temperature level.
That’s where low-e (low-emissivity) glass comes into play.
In combining the performance of conventional glass sheets with more energy-efficient properties, IGUs with low-e glass are designed to provide the ultimate barrier from sunlight andcold drafts — without breaking the bank.
Low-E Glass: Functionality and Efficiency
Low-e (low-emissivity) glass is a practical choice for any building or location where energy efficiency is the priority. In fact, some local codes now demand it.
Even if not required, low-e glass can help you to stop drafts, lower utility costs, and block damaging UV rays. It also allows for an abundance of visible natural light.
Low-e glass is perfect for:
- Glass Doors
- Commercial Storefronts
- Glass Windows
- Glass Walls
- Residential Windows
How is Low-E Glass Made?
Low-e glass is manufactured by layering multiple ultra-thin coatings to each glass pane. The coatings are made of a material that reflects heat and UV rays. The outer layer is designed to improve durability.
A minuscule strip of coating around the pane perimeter’s edge is removed, which allows sealants to bond firmly with the glass, preventing coating corrosion.
To raise efficiency and boost insulation properties, the space between panes is filled with an inert gas (like xenon or krypton). Argon is the most popular choice in the industry.
An Investment in Savings
With the benefit of enhanced insulation against the elements, low-e glass IGUs help to substantially reduce your cooling and heating costs.
Two varieties of low-e glass are used in IGUs: soft coat and pyrolytic hard coat.
Soft coat. This type is more efficient. Multiple layers of coating give reinforced protection from solar heat gain and UV rays.
Pyrolytic hard coat. These are popular for exterior windows in climates known for harsh weather conditions (including strong winds).
High-performing soft coat systems are manufactured with a double or triple layer of silver. IGUs involve materials that are notoriously tricky to work with. That’s why it’s so crucial that they are handled by certified, experienced professionals.
Low e-glass reduces draft and allows lots of visible natural light. Increasingly, state and local codes demand its use.
With our IGUs, you can easily maintain a steady temperature in just about any interior space. Liberty Shielding helps you to keep both the heat and the cold where it belongs — outside — at all times of the year.
