Intus has introduced a new triple-glazed window, the Premier 78 Alu Mira Advanced, which combines a pine frame, high-density foam, and exterior aluminum cladding.
Intus says the windows, which are manufactured in Lithuania with lumber from Germany and Austria, are suitable for Passivhaus construction. The argon-filled glazing has a U-value of 0.088, and when combined with the frame has a U-value of 0.14, the equivalent of about R-7.
The window was introduced at the DesignDC Expo in Washington, D.C., in September. All of the windows are custom-made, with costs ranging from $70 to $85 per sq. ft., Intus says.
Among the features listed by Intus:
- High-density composite foam in the frame that creates a thermal break.
- Triple-gasket weather-stripping to improve airtightness.
- Spacers between panes of glass that reduce the risk of condensation.
Intus says windows can be ordered with various solar heat gain coefficients. Pine frames can be ordered with a lacquer or water-based finish, and the aluminum cladding is available in a number of colors.
