  • Ultima Energy windows are recommended for rooms that are located in a noisy neighborhood or facing the street, as well as rooms where improved insulation is required such as bedrooms and living rooms, etc.
  • The triple-pane construction of the Ultima Energy is the perfect combination of 3 panes, with pane coating and filled with krypton gas to create improved energy efficiency of the whole window
  • Ultima Energy has excellent Uw parameter: 0.99 W/m2K. Krypton gas filled pane construction which conducts heat by F46% less than the most frequently used alternative Argon.
  • Noise Block technology is a combination of various improvements in the roof window construction that reduces noise from the outside as well as impact noise caused by rain which means 50% less noise reduction when compared to standard windows. Noise reduction: 38 dB.
  • The glass and coatings used in Ultima Energy windows are specifically selected to bring comfort and safety to the home. Warm house during winter and no overheating during summer - thanks to two different layers of heat-reflecting and sun-protective coatings on the pane
  • UV-ray protection – thanks to glazing blocking 95% of harmful UV rays while still letting the light in. Strengthened external glass - thanks to the use of thick toughened pane in comparison to 4 mm market standard. Safety of environment underneath the window - thanks to the laminated internal glass which won’t fall into the room in case of impact from the inside
