The solar factor (or g-value) measures the percentage of heat that passes through the glass. The lower the solar factor the higher the solar protection and therefore the higher the performance of the solar control glass.
Solar control glass is typically used to prevent excess heat build up in areas where large amounts of glass are used. For example glass roofs, south-facing elevations. The choice of product is then dependent on the level of performance and appearance requirements, e.g. very reflective, coloured , neutral etc.
You need to look for the small stamp in the corner of the glass. This will give details of the standard the glass is designed to meet, the level it achieved and the supplier. If you cannot see the stamp or want to follow up to check it you should refer to your installer.
Toughened glass is upto five times as strong as ordinary glass which means that it has to be hit much harder in order to break, also when it does break it is into lots of small pieces which are much less dangerous. Laminated glass has the same strength as ordinary glass but it consists of two pieces of glass with a sandwich of plastic interlayer. If the glass does get broken this interlayer holds the whole piece in place so there is no hole left in the window for an intruder to get in through for example or large free shards.
It should be used in low level glazing, glazing in and around doors, overhead and in large areas of glazing to prevent injury following accidental glass breakage.

No, it will however reduce the amount of noise that both enters and leaves your home by approximately 3-4dB over standard double-glazing, which is an audible difference. The noise reduction gained will be dependent upon the quality of your window frames and the type and level of noise you are trying to cut out.
