  • Dakea Ultima is proof that in the search for better, we have no equal
  • These exceptional roof windows excel with their superb technical parameters, unique noise reduction system, increased durability, and comfort.
  • Dakea Ultima has an innovative noise reduction system, which mutes up to 50% of traffic and rain noise. The superb energy efficiency of 1.2 W/m2K is provided by outstanding glazing with two low-emission coatings and a krypton gas filling.
  • The pane preserves heat in winter and protects against it in summer. Additionally, it blocks 95% of the UV radiation to prevent color fading. For care-free maintenance, the external pane has a self-cleaning coating.
  • Dakea Ultima is reinforced and resistant to category II hurricanes. Its external pane is extra thick and toughened and the internal one is laminated to ensure full impact protection and a lifetime warranty against hail damage.
  • The solid wooden frame with a central axis of rotation has 2 layers of lacquer and comes in 2 colors: natural wood and white.
  • We are so certain of the high quality of our windows, that we give them a 20-year guarantee - the longest guarantee on the market, with no registration required.
