Low E glass coatings work by reflecting or absorbing IR light (heat energy)
Thickness of low E coating and position in window (#2 or #3 surface) dictate how window will perform
Installed on #3 surface of an insulated glass unit (IG) low E coating will reflect IR heat from inside room to help reduce energy loss during cold months
Installed on #2 surface of an IG unit, low E coating will reflect or absorb IR heat from outside, thereby reducing solar gain and cooling costs during warm months
Low E terminology with solar selective hard-soft-coating, sputtered and paralytic to deal with needs facts
Feasible visible light transmittance to shade outdoor light
Lower solar transmittance
Prevents solar heat radiation into room effectively
High and far infrared ray reflectance
Low heat-transfer co-efficient (U value)
Limits outdoor secondary heat radiation into room in summer
Applications:
Suitable for both south and north areas, can prevent most solar radiation into room in summer/winter, intensity of solar radiation 1/3 of that in summer, keeps thermal insulation property unaffected
Suitable for buildings, abundant ornamental and shading outdoor light effect
Insulating glass (low-e coating surface #2 from outside to inside) with energy conservation
Note: Not all certifying agents offer online lookup, and some have a lag time for posting new certificates. If you are unable to find a certificate online, contact the certification agency or supplier for further verification.
