About every six months, I report on new products that catch my eye. This round-up features products from both sides of the Atlantic Ocean: high-performance windows from Maine, Ontario, and Lithuania; high-performance doors from Poland; and high-performance tapes from Switzerland.
Linwood Windows is a small window manufacturer in Tenants Harbor, Maine. Owned by Richard Cohen, the company makes European-style tilt/turn windows out of Douglas fir. All windows are custom made; the usual lead time is 12 to 14 weeks.
The fir frames are milled in Maine using European shaper blades. According to Cohen, windows using frames milled with similar shaper blades have met the strict Passivhaus Institut standard for certified Passivhaus windows.
Linwood Windows can be ordered with double, triple, or quadruple glazing. A wide variety of glazing options are possible, including triple glazing with a center-of-glass U-factor of 0.13.
Linwood’s triple-glazed tilt/turn windows cost between $120 and $160 per square foot.
Intus Windows are manufactured in Lithuania and distributed by Intus Consulting in Washington, D.C. Intus sells both vinyl-framed and wood-framed windows. All Intus windows are tilt/turn style windows with triple weatherstripping. The company’s triple-glazed vinyl windows are some of the least expensive high-performance windows available in the U.S.
Most of the windows that Intus sells in the U.S. have triple glazing with two low-e coatings and warm-edge spacers. (However, if the customer prefers, double glazing can also be ordered.) The windows are glazed at the Intus factory in Lithuania. Intus assembles its own insulated glazing units (IGUs), using Saint Gobain glass for Intus wood windows and Guardian glass for Intus vinyl windows. High-solar-gain triple glazing is an available option.
Intus vinyl windows use vinyl lineals (profiles) manufactured by Deceuninck Group (Belgium). None of Intus’s vinyl windows are Passivhaus-certified.
