What is the difference between SGG CLIMALIT double glazing with low emission glass and SGG CLIMALIT without low emission glass?
The low emissions layer in a pane of glass is a neutral reduction layer that greatly reduces heat losses caused by radiation, reflecting most of the heat back into the heated premises.  The low emission is achieved by depositing metallic oxides and noble metals through cathodic pulverisation under vacuum onto one of the glass surfaces that subsequently  forms part of  SGG CLIMAT  double glazing. In short, the result of the incorporation of a low emission glass (SGG PLANITHERM, SGG PLANITHERM S, SGG EKO PLUS S, SGG PLANISTAR…) in double glazing is the saving of energy, less loss of heat generated within the premises and therefore greater comfort, with a significant saving in the cost of keeping the premises at a comfortable temperature.

Where is the low emission layer situated in a SGG CLIMALIT double glazed unit?
Inside the SGG CLIMALIT double glazing, the treated surface is positioned in contact with the air chamber.  In the case of SGG PLANITHERM it is on surface 3, while in the cases of SGG PLANITHERM S and SGG PLANISTAR it is on surface 2.

Which forms of glazing are most suitable for protection against the sun and for maximum light?
Traditionally, choosing products that provide a high level of protection against the sun has meant the loss of light levels, in direct proportion to the degree of protection required.  The latest generation of Saint-Gobain Glass products has succeeded in incorporating low emission layers, next to the high powered sun protection layers which together provide high solar protection with surprisingly high light levels. The question is answered then, through the incorporation of SGG COOL-LITE K solar control glass into SGG CLIMALIT double glazing. SSG PARASOL coloured glass can provide the solutions in the colour the client wants, and SGG PLANILUX colourless glass will provide colourless glass solutions.

What is the most suitable type of glass for noise insulation?
For streets where there is not a lot of noise: SGG CLIMALIT SILENCE composed of 33.1 SGG STADIP SILENCE + a 12 mm chamber + 4 mm SGG PLANILUX which has the following characteristics: Rw: 34 dB, Ra, tr: 30 dB. For streets with a medium noise level: SGG CLIMALIT SILENCE composed of 44.1 SGG STADIP SILENCE + a 12 mm chamber + 8 mm SGG PLANILUX.  Characteristics: Rw: 40 dB, Ra, tr: 35 dB. For streets where there is a high level of noise:  SGG CLIMALIT SILENCE composed of 55.1 SGG STADIP SILENCE + a 20 mm chamber + 44.1SGG STADIP SILENCE.

How can the thicknesses of the glazing that is required be established?
The thickness of glazing is determined according to the following factors: the application of the glazing (vertical or horizontal openings); the forces it has to withstand (action of the wind, overloading), and safety requirements (physical, anti-assault, bullet proofing). For each case CITAV, SGG’s technical department in Spain, has programmes and other means for helping you decide the thicknesses recommended in each situation.

What are the differences between the characteristics and applications of PF and RF types of anti-fire glass?
PF (fire protective) glass, which in the European system of symbols is “E”, has the following characteristics: mechanical stability, impenetrable by flames, impermeable to inflammable gases.  RF (fire resistive) glass, which in the European system of symbols is “EI”, has the three characteristics of PF glass plus thermal insulation.

What thickness and composition should be used for glass that will be walked on?
For dimensions around 1000 x 1000 mm. laminated SGG STADIP 10+10 is normally used.

Is it necessary to temper SGG PARASOL solar control glass, both in single glazing and in SSG CLIMALIT double glazing?
They must both be tempered, except when installed in a north facing position.
