Differences Between Planitherm Total+ FG and Planitherm One II

Both Planitherm Total+ FG and Planitherm One II are high performance low-emissivity (Low-E) glass coatings from Saint-Gobain, designed to improve energy efficiency and comfort. However, they have distinct properties that make them suited for different applications.

Coating Type	Planitherm Total+ FG	Planitherm One II
Thermal Efficiency	Excellent insulation with a low U-value	Even lower U-value, providing best-in-class insulation
Energy Savings	Reduces heat loss and energy costs	Maximises energy efficiency with superior insulation
Appearance	Neutral, clear glass with high light transmission	Also clear, but optimised for maximum performance
Condensation Control	Helps reduce condensation	Further minimises condensation due to its high insulation properties
Best Suited For	Standard high performance double glazing & larger glazing applications (façades, curtain walling)	Premium double glazing where exceptional insulation is required
Used in Glasscraft Products	Hytherm	Hytherm Extra Hytherm Security Extra Hytherm Ultimate

Which One Should You Choose?

Planitherm Total+ FG is ideal for high quality, energy efficient double glazing, such as our Hytherm range. It balances performance, clarity, and durability, making it suitable for homes and commercial applications, including larger glazing.

Planitherm One II takes thermal performance even further, making it perfect for projects where the highest insulation levels are required. That’s why it features not only in Hytherm Extra and Hytherm Security Extra but also Hytherm Ultimate our gold standard triple glazed unit.
