Different available types of Insulated Glass
Insulating glass units (IGU) are available in numerous different types based on their application and need for insulation. The design versatility of contemporary glass allows room for modifications based on the user’s needs. The types of double glazing glass are differentiated based on cavity-filling material, additional coatings, and sealing layers.
1. Argon-Filled Insulated Glass
Argon gas is widely used in insulating glass units to fill up the cavity between the layers or panes of glass. An inexpensive, colorless, odorless, and non-toxic argon gas greatly contributes to the enhancement of the performance of insulated glass. Noble gases like argon are usually preferred over the air as the presence of air in the cavity often fogs up the glass due to the high percentage of moisture. Air does also has lesser insulating properties than the noble gas counterparts. Argon-filled insulated glass significantly improves U-Value and soundproofing. They also help in minimization of heat transfer and can be used in congestion with Low-E coatings. Besides this, argon gas doesn’t corrode the window frames and also does not contaminate the environment with toxicity.
2. Low-E Insulating Glass Unit
Low-E coating glass is also known as low-emissivity glass are designed to reduce the U-Factor and regulate heat transfer. Emissivity coating is accomplished by the application of microscopically thin layers of metal oxides which also gives the glass surface a greenish tint. The additional coating of metal minimizes the heat transfer and makes it a more effective insulating unit. The combination of both Low-E coating and space or gas-filled cavity results in the augmentation of thermal insulation. These coatings can reduce energy loss by up to 50% and promotes the idea of energy conservation. Special Low-E coatings are designed to allow passage of certain types of light to illuminate the interior space.
3. Dual-Seal Silicon Insulated Glass Unit
Dual seal-silicone insulated glass units are modernized double glazing glass which stands apart in terms of longevity and durability. The silicone seal or commonly known as PIB forms the most effective barricade against the atmospheric moisture and helps maintain the insulation properties of the glass. Silicone sealant bonds are incredibly resilient which makes them durable and adequate for commercial and industrial glass use. Insulated glass can be fabricated as PIB or silicone seal insulated glass due to its incredible design versatility and flexibility. Their lower moisture penetration rate helps maintain its insulation property without compromising on the translucency of the glass. Lower moisture means fewer changes of glass fogging up and becoming cloudy.
