Solar Low E Glass

For countries where difference in temperature is more solar control low e glass is the most suitable glass.

Solar low e glass.

Pilkington solar e is the latest evolution to the pilkington solar e family of pyrolytic coated low reflective solar control glasses with low e properties. The products are available in a range of colours clear evergreen. Long wavelengths or heat are filtered out while short wavelengths the visible light spectrum are allowed to pass through. According to the vitro formerly ppg glass education center there are several factors used to measure the effectiveness of glass with low e coatings.

Solar heat gain coefficient shgc. But the beauty of glass is pointless if the people inside the building are uncomfortable or if energy inefficiency makes the building too expensive to operate. Solar control low e glass is one type of high performance glass which cuts up to 60 of solar heat entering the room and also provides thermal insulation. Pilkington solar e is a range of good solar control performance on line coated glasses offering low solar heat coefficient gain low reflectivity reduced glare and low emissivity.

This is the. Because of its neutral color solarban z75 glass harmonizes well with other clear and color neutral solar control low e glasses such as solarban 67 glass and solarban r100 glass. Solarban r100 glass is a neutral reflective low e glass with an excellent solar heat gain coefficient shgc of 0 23 and visible light transmittance vlt of 42 percent. Solarban z75 glass consists of solarban 70 solar control low e coating on optiblue tinted glass with clear glass as the inboard lite.

Low emissivity hard coated glass that provides thermal insulation with passive solar gain energy select 73 plus is a pyrolytic low emissivity glass that combines excellent year round energy efficiency with hard coat durability. It also means that 84 of the long wave radiation striking the surface of the glass is absorbed and only 16 is reflected. This is the fraction of incident solar radiation that is admitted through the window. By comparison low e glass coatings can have an emittance as low as 0 04.

Low e glass solar control and passive low e glasses glass is one of the most popular and versatile building materials used today and it provides a dramatic aesthetic. Such glazing would emit only 4 of the energy possible at its temperature and thus reflect 96 of the incident long wave infrared radiation.
