How anyone can be more energyefficient with Rationel glass panes

At Rationel, all of our bespoke windows are built to an exceptional level of durability, and designed to retain the optimum level of indoor light and warmth – reducing emissions while contributing to a more comfortable family ambience in the home.

As well as all Rationel windows being approved according to EN 1279 requirements and coming with argon-filled glazing and a warm-edge spacer as standard, our broad range of products all boast their  own individual features that can help improve your energy rating.

Read on to learn more about our different windows and what they can do for your energy efficiency. 

Rationel ENERGY

Energy-efficient glazing reduces thermal loss, and therefore your overall heating bills. The space between the double glazed panes is filled with argon gas, which is a much better insulator than air. The inner glass layer of an energy-efficient double glazed unit has a thin metal coating that reflects the heat back into the room. 

This coating is neutral and so allows maximum sunlight into rooms, offering you the benefits of additional free heat. Rationel ENERGY panes not only create a bright, pleasant indoor environment but also reproduce colours as neutrally and naturally as is technically possible. They meet energy class A requirements. 


Rationel Secure

Secure

Rationel SECURE panes have been tested in accordance with several national and European safety standards, included Secured by Design.

The most common break-in route attempted by intruders is via the window pane. Our laminated glass products provide a significant security advantage, as they take even more time and effort to break than the average Rationel window.

See how a Rationel window can withstand even the most extreme attempts of forced entry.


Rationel Obscure

Obscure

Rationel OBSCURE panes are designed to restrict the view into private areas such as bathrooms. As the translucent patterns are located on the inside of the panes, they can still be cleaned like traditional glazing.

Rationel SAFETY

Safety

Rationel SAFETY panes can be made of toughened glass, laminated glass or a combination of both.

Safety glass reduces the risk of injury if someone falls into the pane, breaking the glass. The toughened glass is designed to fall out of the sash and shatter into small, harmless pieces.

A laminated glass pane will remain as one unit if it is broken, making severe injury on these windows next to impossible.

Rationel SAFETY has been tested and marked according to several national and European standards.

 


Rationel FACADE

Facade

Rationel FAÇADE is used in buildings either to create a visually coherent façade or for special colour effects.

FAÇADE is well suited to storey divisions as well as ventilated and insulated panels, and is available in special colours on request.

 

 


Rationel SOUND

Sound

If you are often subject to have traffic in your area, or live near a railway line, noise pollution can be a constant frustration.

Thankfully, this problem can be solved with our noise-reducing panes. Rationel SOUND panes are glazed with two glass sheets that act as a break, dramatically reducing the movement of sound into your home.

 


Rationel SOLAR

Solar

Rationel SOLAR is used mostly in office and commercial buildings that have large south and west glass façades, where overheating can occur during the summer months.

We offer five types of SOLAR panes that limit the amount of sunlight and heat coming into a building, depending on the light and heat shielding levels required.

SOLAR Green and Grey have tinted glass which reduces the amount of light and heat coming into a building.
