  • Ultima Energy PVC window is recommended for rooms located in a noisy neighborhood or facing the street, as well as rooms where increased resistance to humidity and dirt is required such as bathrooms and kitchens, etc.
  • The triple-pane construction of the Ultima Energy PVC is the perfect combination of 3 panes, with pane coating and filled with krypton gas to create improved energy efficiency for the whole window.
  • Ultima Energy PVC has excellent Uw parameter: 1.0 W/m2K. Krypton filled pane construction which conducts heat by 46% 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, overall, means 50% better noise reduction when compared to standard windows. Noise reduction: 38 dB.
  • The glass and coatings used in Ultima windows are specifically selected to bring comfort and safety. 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 – consists of the use of thick 6 mm toughened pane in comparison to 4 mm market standard. Safety of environment underneath the window -consists of laminated internal glass which won’t fall into the room in case of impact from the inside.
