When light enters through a glazed surface, a portion of the energy is reflected, another transmitted and the balance absorbed into the glazing. The energy that is absorbed into the glazing heats up the pane of glass and this in turn reradiates energy from both sizes of the glazing.

There are several methods to reduce the energy flow by sunlight through glazing some of which are applied to the glazing directly while others include the application of blinds internally or externally. Verosol presents an oppertunity to apply a very effective sun control solution in the form of a pleated or roller type blind to the inside of the glazing.

The solar performance figures are obtained from a set of tests conducted by the Netherlands Organiseation for Applied Scientific Research (TNO).

Given that a typical summer day can provide an incident solar radiation of up to 900W/m², the experimental values below allow the estimation of how much of the incident solar radiation enters through the glazing. For the purpose of the estimation, it is assumed that all the reflected energy and half the absorbed energy are kept from entering the room.
