Intus Introduces a Wood-Framed Window

Posted on October 10, 2013 by Scott Gibson

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 claddingMaterials used on the roof and walls to enclose a house, providing protection against weather. .

Intus says the windows, which are manufactured in Lithuania with lumber from Germany and Austria, are suitable for PassivhausA residential building construction standard requiring very low levels of air leakage, very high levels of insulation, and windows with a very low U-factor. Developed in the early 1990s by Bo Adamson and Wolfgang Feist, the standard is now promoted by the Passivhaus Institut in Darmstadt, Germany. To meet the standard, a home must have an infiltration rate no greater than 0.60 AC/H @ 50 pascals, a maximum annual heating energy use of 15 kWh per square meter (4,755 Btu per square foot), a maximum annual cooling energy use of 15 kWh per square meter (1.39 kWh per square foot), and maximum source energy use for all purposes of 120 kWh per square meter (11.1 kWh per square foot). The standard recommends, but does not require, a maximum design heating load of 10 W per square meter and windows with a maximum U-factor of 0.14. The Passivhaus standard was developed for buildings in central and northern Europe; efforts are underway to clarify the best techniques to achieve the standard for buildings in hot climates. construction. The argonInert (chemically stable) gas, which, because of its low thermal conductivity, is often used as gas fill between the panes of energy-efficient windows. -filled glazingWhen referring to windows or doors, the transparent or translucent layer that transmits light. High-performance glazing may include multiple layers of glass or plastic, low-e coatings, and low-conductivity gas fill. 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.
