There is no better glazing solution for conservatory side walls than Planitherm 4S. This special option in the market-leading Planitherm family from Saint-Gobain offers a high level of thermal insulation in colder months, whilst being able to manage the risk of excess heat gain even in the strongest, direct summertime sunshine.

That’s why we call it “4 Seasons” – whatever time of year, Planitherm 4S has the right blend of multifunctionality to provide an effective solution.

Planitherm 4S is designed for use in double glazed units in all frame types for both residential new-build and replacement markets, ideally for:

• Windows and skylights in residential buildings and private domestic housing
• Conservatories and patio doors.

Planithern Total+ - optimal performance 

Why choose Planitherm 4S?

• Thermal insulation: reduces heat loss more effectively than traditional low-E products

• Solar protection: reflects up to 56% of solar heat gain through conservatory sidewalls and as much as 79% when used in conjunction with Bioclean Aqua in the roof areas

• Energy efficient: energy consumption for a conservatory can be reduced by as much as 28%, meaning that Planitherm 4S can deliver homes with lower CO2 emissions that cost far less to run

• Visual comfort: maximum natural light and reduced glare enhances how the conservatory or room looks

• Neutral appearance: beautiful neutral appearance provides consistency with the glazing in the rest of the property
