Window recommended for rooms located in a noisy neighbourhood 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 have excellent Uw parameter: 0.99 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 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 use of thick 6 mm toughened pane in comparison to 4 mm market standard. Safety of environment underneath the window - thanks to laminated internal glass which won’t fall into the room in case of impact from the inside. Easier maintenance of the glass from the outside - thanks to the application of exclusive titanium coating which cleans the window with rain water.
