SGG Planitherm 4S Glazing


SGG Planitherm 4S Glazing

With an optimum g-value of 0.43 SGG PLANITHERM 4S provides excellent levels of solar protection for conservatory side walls, reducing unwanted heat by more than 2/3.

With a U-value of 1.0W/m2K its thermal insulation far exceeds all current available products, whilst still allowing excellent levels of natural light and the neutrality you would expect from the SGG PLANITHERM range. Furthermore when combined with SGG BIOCLEAN COOL-LITE ST in the roof glazing, a g-value as low as 0.29 can be achieved, blocking over 70% of direct heat from the sun where it is needed most. Add to this the benefits of our dual-action self-cleaning coating and reduced glare and you have an all round glazing solution.
