What Does Low E Glass Mean In Construction?
Low-E glass is a special type of window or glazing system that is designed to reduce the amount of heat, light, and ultraviolet radiation that can pass through it.
It does this by having a microscopically thin metallic coating on one side which is partially reflective, blocking some incoming and outgoing radiation while still allowing visible light to pass through.
Low-E glass has been shown to greatly reduce energy loss in buildings while still allowing daylight inside. It also blocks most UV radiation which can cause fading of furniture and other objects over time.
Low-E glass is becoming more popular in construction projects as it provides increased insulation properties and helps create an energy-efficient building.
What Is The Purpose Of Low-E Glass?
Low-E glass is designed to reduce the amount of ultraviolet and infrared light passing through windows while retaining the majority of visible light that provides natural illumination.
The coatings used on Low-E glass contain microscopically thin layers of metal or metallic oxide which reflect away excess heat, providing greater insulation than standard windows without blocking the daylight.
Low-E-coated glass can improve energy efficiency by reducing cooling costs during summer months and helping prevent furniture fading due to direct sunlight exposure.
It also helps make interior spaces more comfortable by controlling temperature extremes throughout the year.
In summary, Low-E glass is an effective solution to help reduce energy costs, preserve interior décor, and maintain comfortable temperatures in any environment.
What Is The Difference Between Low-E Glass And Regular Glass?
Low-E glass is significantly different from regular glass in that it incorporates a thin transparent coating on the interior side of the glass which helps to reflect interior temperatures back inside and reduce energy loss.
This type of glass not only improves insulation but also aids in maintaining desired indoor temperatures. Regular glass has no such coating, so while it may be cheaper to purchase, it does little to help with energy efficiency.
What Does The E Stand For In Low-E Glass?
The letter “E” in Low-E glass stands for “emissivity,” which is the ability of a surface to emit or radiate energy relative to other materials. Low-E glass consists of a coating applied to one or both sides of the glass that reduces its emissivity, thus reducing energy loss.
This special coating helps lower the amount of heat transferred through the window, improving the energy efficiency of buildings and homes.
Additionally, this type of glass blocks ultraviolet light, reducing fading in fabrics such as furniture and carpet due to sun exposure while still allowing visible light into a room.
What Are The Disadvantages Of Low-E Glass?
- Low-E glass is generally more expensive than uncoated standard toughened glass, thus making it a disadvantage for some people.
- Additionally, the performance of Low-E windows can be affected by stronger air conditioning systems which can counteract any energy savings provided by the Low-E glazing.
Low-E windows may also be adversely affected by overheating due to direct sunlight, as the coating doesn’t defend against heat entirely – instead only allows in some very specific frequencies of light.
Lastly, its condensation resistance may be weaker than standard windows due to a lack of insulation properties, meaning that low-E glass must be chemically treated in order to reduce fogging and condensation.
What Are The Different Types Of Low-E Glass?
The two main types of Low-E glass available are Hard Coat Low E and Soft Coat Low E. Hard coat Low E is applied to the glass when it first emerges from the furnace and is fused onto the surface as it cools.
This method results in an inert, durable coating that retains its efficiency over time, making it suitable for exterior applications. Soft coat Low E is applied at a later stage in production, typically during tempering or lamination processes.
It provides superior solar control performance compared to hard coat but has limited durability and must be treated with care.
Both types of Low E glazing can provide excellent energy savings benefits by reducing heat loss or gain through windows while still allowing natural light into your space.
