Quadruple glazing

Are you looking for roof windows that provide exceptional thermal comfort, quietness, and maximum energy savings? Choose roof windows with quadruple glazing – an innovative solution perfect for energy-efficient and passive houses. These windows consist of four glass panes separated by three layers of noble gas (usually argon or krypton), offering excellent thermal and sound insulation, minimizing heat loss and external noise.

Benefits of quadruple-glazed roof windows:

Maximum thermal insulation: Quadruple-glazed windows achieve exceptionally high insulation values, further reducing heat loss in winter and preventing overheating in summer. They are the optimal choice for energy-efficient and passive houses, enabling significant savings on heating and cooling costs.
Superior sound insulation: The additional glass pane and noble gas layers significantly dampen external noises, ensuring a quiet and relaxing atmosphere in the attic – particularly near busy streets or airports.
Minimized condensation: Due to excellent thermal insulation, condensation on the inner side of quadruple-glazed windows occurs less frequently, significantly reducing the risk of mold and mildew formation.
Enhanced living comfort: These windows guarantee stable room temperatures, eliminate cold sensations near windows in winter, and prevent excessive heating in summer.

When to choose quadruple-glazed roof windows?

✅ For energy-efficient and passive houses.
✅ For living areas such as bedrooms, children's rooms, or living rooms where thermal and acoustic comfort is a top priority.
✅ When maximum energy savings and minimal heating costs are critical.
✅ When the house is located in a region with extreme climate conditions or near noisy sources.
