Smart glass, also known as switchable glass, dynamic glass, and smart-tinting glass, is a type of glass that can change its optical properties, becoming opaque or tinted, in response to electrical or thermal signals. This can be used to prevent sunlight and heat from entering a building during hot days, improving energy efficiency. [1]
In a heating-dominated climate, the second type of low-e coating is more appropriate. This is Passive Low-E, where the goal is to retain heat inside the building. These coatings do not block as much of the short-wave infrared light from the sun, but do block any long-wave infrared light coming from the inside, functioning as somewhat of a ...
These profiles are called thermal breaks and are made from glass fibre reinforced polyamide 6,6. The proportion of glass fibre in the profiles is 25%. The material used for this insulating bar stands out for its low thermal conductivity value (0.30 W/m2K) and its good mechanical properties even at higher temperatures.
Borosilicate glass is a type of glass with silica and boron trioxide as the main glass-forming constituents. Borosilicate glasses are known for having very low coefficients of thermal expansion (≈3 × 10 −6 K −1 at 20 °C), making them more resistant to thermal shock than any other common glass.
Spectrally selective films act by blocking certain wavelengths of the sun's infrared radiation and reject heat without reducing natural light. Security films are applied to glass so when the glass is broken it holds together, preventing dangerous shards from flying about, or making it more difficult for an intruder to gain entry.
One university study shows that this heated glass technology is more efficient than other electric heating and can be more efficient than natural gas heating. [5] Some environmentalists dispute the idea that this is an efficient heating system because even high e-value windows are poor insulators compared to insulated walls, and they believe ...
