Obscure panes

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.

All windows and doors from Rationel are delivered with energy glass with a warm edge spacer, which reduces cold bridges and the occurrence of dew and condensation on the windows. The space between the panes of glass is also filled with the environmentally friendly argon gas, which provides significantly better insulation and reduces heat loss. The inner glass pane has a thin, transparent metal coating, which reflects the heat back to the room and ensures maximum light incidence.

Frosted or patterned glass

Designed to reduce transparency, Rationel OBSCURE glass is the ideal choice for any room where both privacy and natural light are essential, such as a bathroom.

Acoustic control

If you live in a big city, near a busy road, or close to any source of noise, Rationel SOUND glass offers great acoustic control, helping absorb sound and improve the comfort of your home.

Solar control

Designed to minimise solar gain – free heat from the sun – Rationel SOLAR glass is the ideal choice for south or west facing windows or facades, to help ensure a comfortable temperature in every room.

Difficult to break, Rationel SECURE glass features laminated panes designed to deter even the most persistent burglar. Rationel SECURE glass has been tested in accordance with several national and European safety standards, including Secured by Design.
