Solar Low E Glass

Solar low e glass.

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. 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. Its exceptional solar control characteristics make solarban z75 glass an excellent choice for warmer climate zones with high cooling costs.

They keep interiors warmer in winter and cooler in summer. Such glazing would emit only 4 of the energy possible at its temperature and thus reflect 96 of the incident long wave infrared radiation. 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. According to the vitro formerly ppg glass education center there are several factors used to measure the effectiveness of glass with low e coatings.

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. 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. 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. Solar heat gain coefficient shgc.

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. Long wavelengths or heat are filtered out while short wavelengths the visible light spectrum are allowed to pass through.

Low e meaning low emissivity is an extremely thin layer of metallic particles or more commonly several layers applied to the glass that in simple terms allows the glass to act like a sieve. 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.
