a new concept for year-round comfort, keeping you warm in winter and cool in summer

Product Benefits

Keep cool in summer?

The SGG PLANITHERM 4S glass is combined with our solar control roof glass products to create high performance conservatory roof glass with outstanding thermal efficiency.

However, when purchasing a conservatory, many people choose solar control glass for the roof, but do not consider it for the sidewalls. In south or west facing conservatories in particular, the amount of heat build up can make the conservatory uncomfortable, even when solar control glazing has been used overhead.

When used alone in conservatory side walls, SGG PLANITHERM 4S:

  • Provides excellent levels of solar protection for conservatory side walls, reducing unwanted heat by more than 57%
  • Has an attractive neutral appearance giving you a clear view of your surroundings
