| Amount of Light |
|
Different materials and different tints of materials provide
varying amounts of light into the building. In clear format
most single skin rooflight materials will have a light transmission
of 80%-90%. This must however be checked for the specific
rooflight being used; material thickness, diffusing or colour
tints, and number of skins can all affect overall light transmission.
In some situations the amount of light entering the building
needs to be controlled, usually to prevent overheating. Tinted
materials will limit the light entering the building. It is
impossible to give a general guide to the light transmission
achieved through the various tinted options available, as
these vary not only from material to material but also from
manufacturer to manufacturer.
