As the demand for sustainable living grows, energy efficiency has become a top priority in both residential and commercial construction. From insulation to lighting and appliances, every element of a building now plays a part in reducing energy consumption and environmental impact. One of the most effective ways to improve a building’s energy performance often overlooked is through its windows.
That’s where Planitherm comes in. Manufactured by Saint-Gobain, Planitherm is a leading brand of energy-efficient glazing that helps maintain indoor comfort while dramatically reducing heat loss. Whether you’re building a new home or upgrading existing windows, Planitherm glass offers an intelligent solution to reduce energy bills, improve comfort, and contribute to a greener future.
What Is Planitherm?
Planitherm is a range of low-emissivity (low-E) glazing products designed to optimize thermal insulation. Using advanced coating technology, Planitherm glass reflects heat back into the building during winter and helps regulate solar gain during the warmer months all without reducing the amount of natural daylight entering the space.
The result is energy-efficient glazing that enhances comfort, reduces reliance on heating and cooling systems, and supports sustainable living without compromising on aesthetics.
How Does It Work?
At the heart of Planitherm’s performance is a microscopically thin, transparent coating applied to one side of the inner glass pane. This coating is made from metallic oxides, including silver, which is known for its reflective properties.
Here’s what happens:
- In winter, the coating reflects interior heat back into the room, preventing it from escaping through the glass.
- In summer, certain Planitherm variants reduce solar gain, helping keep rooms cooler and reducing the need for air conditioning.
- Throughout the year, the glass allows natural light to pass through, keeping interiors bright and welcoming.
This intelligent control of thermal energy makes Planitherm one of the most effective glazing options available for improving a building’s energy performance rating.
Key Benefits of Planitherm Energy Efficient Glazing
1. Lower Energy Bills
By keeping heat inside during colder months and reducing heat entry during summer, Planitherm helps reduce reliance on heating and cooling systems. This leads to lower utility costs year-round, making it a smart long-term investment.
2. Enhanced Comfort
Planitherm helps maintain a consistent indoor temperature across all seasons. No more cold drafts near windows in the winter or overheating in the summer just a more comfortable living or working environment.
3. More Natural Light
Unlike older or heavily tinted energy-saving glass, Planitherm offers excellent light transmission. This means your space remains naturally lit without sacrificing energy efficiency, reducing the need for artificial lighting during the day.
4. UV Protection
The special coating on Planitherm also blocks a significant amount of harmful UV rays, helping to protect your furniture, carpets, and artwork from fading due to sun exposure.
5. Environmentally Friendly
Using less energy to heat or cool your home means you’re also reducing your carbon footprint. With Planitherm, you’re contributing to a more sustainable future one window at a time.
Types of Planitherm Glass
Planitherm isn’t a one-size-fits-all solution. Saint-Gobain has developed a range of products to suit different building needs and environments:
-
Planitherm Total+
The most commonly used variant for general residential use. It offers excellent insulation and light transmission—ideal for homes that need year-round thermal comfort.
-
Planitherm One
This version provides ultra-low U-values, meaning it offers exceptional thermal insulation. It’s often used in energy-efficient or passive house projects.
-
Planitherm 4S
A multifunctional glass that delivers thermal insulation and solar control in one. Perfect for glazed extensions, conservatories, or rooms with large windows exposed to sunlight.
-
Planitherm Comfort and Comfort Plus
These advanced options go beyond thermal performance. They also offer noise reduction, extra UV protection, and enhanced security—ideal for homes in busy or high-sunlight areas.
Where Can Planitherm Be Used?
Thanks to its versatility and range of performance options, Planitherm can be used in nearly every type of window or glazed area, including:
- Residential windows and doors
- Conservatories and sunrooms
- Skylights and roof glazing
- Commercial buildings and offices
- Schools, hospitals, and public facilities
It’s suitable for both new constructions and renovation projects, offering flexibility for architects, builders, and homeowners alike.
Contribution to Green Building Standards
Choosing Planitherm glazing doesn’t just benefit your energy bills—it also supports compliance with green building certifications like:
- BREEAM (Building Research Establishment Environmental Assessment Method)
- LEED (Leadership in Energy and Environmental Design)
- Passivhaus (Passive House standards)
Because it contributes to improved thermal performance, reduced CO₂ emissions, and better indoor environmental quality, Planitherm can help your project qualify for these internationally recognized sustainability ratings.
Installation and Maintenance
Planitherm glass is usually supplied as part of a double or triple glazed unit and installed in the same way as standard glazing. It’s compatible with most frame materials, including:
- UPVC
- Timber
- Aluminium
- Composite frames
Once installed, Planitherm requires no special maintenance. The coating is sealed inside the glazing unit, so it won’t wear off or degrade with cleaning. Just keep your windows clean as usual to maintain their clarity and performance.
Cost vs Value: Is It Worth It?
While Planitherm may come at a slightly higher initial cost than standard glazing, the long-term savings on energy bills, increased comfort, and added property value make it a cost-effective investment.
Homeowners typically see a noticeable difference in indoor temperature regulation and reduced heating costs, especially in colder climates.
Final Thoughts
Planitherm – energy efficient glazing is not just about saving money—it’s about building better homes and workplaces. It’s about enhancing comfort, protecting the environment, and preparing for a future where sustainability is no longer optional but essential.
Whether you’re retrofitting a family home, designing an eco-friendly office, or building a new low-carbon property, Planitherm offers a high-performance glazing solution you can trust.
When it comes to energy efficiency, smart design, and sustainable living, Planitherm glass is a clear winner.
