Reading the values

Light transmission (LT): Share of visible light that passes through the sheet.
Solar factor (SF): Ratio between the total energy transmitted inside and the total solar radiation.
Shading coefficient (SC): Solar heat gain compared with a reference clear glass; lower means less heat.
Thermal transmittance (U): Rate of heat loss through one square metre per degree of temperature difference; lower insulates better.
