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.

    Q. "Why is this in blogs?"

    A. This is a news story, not a blog. If you are ever in doubt about what kind of story you are reading, you can check out the list of stories in one of our "landing pages."

    Q. "Nothing new here."

    A. GBA sometimes announces new products that we think will be of interest to our readers. If the headline for the story doesn't interest you, just don't read it.

    Q. "Please explain the $70 / square foot price tag on this?"

    A. Of course the price of your window order will vary depending on several factors. Large windows cost less per square foot than small windows. Fixed windows cost less per square foot than operable windows. As they say, "your mileage may vary."

    Martin ...
    Well the website is having some really hard time with Opera ( never tried in other browsers )
    because i never ever clicked on the news section ( just found out it was there )
    and this one was in the list of the blogs, which is pretty much with QA the only place i look at regularly here ...

    But anyhow, thanks for pointing the sections out ... after almost 2 years here , i never realized about the news section ( n00bified ! )

    The headline interested me, i just don't feel there is anything new in that product.
    It it was only to point out availability... changes the purpose of the article.

    About the price,
    the only reason i would consider using wood is for reducing manufacturing costs.
    But it doesn't seem to be the case here .
    We need better windows are a more reasonable cost soon.
    Very hard to sell windows@ 60$/sqft + to clients , based solely on their thermal performance.
