PHI-A Certified, Simulated Double-Hung, Landmark Windows

Victoria_BEWISOThe VICTORIA Window

This well-crafted fenestration comes to us from BEWISO (short for “BEst WIndow SOlution”). It’s manufactured in Austria by timber industry experts focused on offering the highest possible visual aesthetic, while maintaining Passive House levels of comfort and efficiency.

The VICTORIA window is Certified by the Passive House Institute, achieving Efficiency Class A for both the operable and fixed versions. Click the Certificate image below to download a full PDF. This is the only Passive House Certified simulated double-hung window available in North America.

See the specification sheet HERE.

The Historic Preservation Solution

The VICTORIA is historic preservation friendly, with extra-narrow frames and mullions. Until now, it’s been a challenge to find a solution to the problem of fenestration for high-performance retrofits located in historic districts. Concerns regarding the aesthetics of windows from historic preservation boards can hold up construction projects for months.

The greenest building is the one that’s already there. Retrofitting our existing building stock is vital to decarbonizing our built environment. That’s why 475 has been dedicated to the concerns of Historic Masonry Retrofits, and Wood Frame Deep Energy Retrofits.

As the only Passive House Certified simulated double-hung window available, VICTORIA allows you to more easily balance the insulation levels of retrofits projects – something retrofit specialists have had to struggle with in the past using models that were not quite there, thermally speaking.

    Very interested, lots of questions.

    Do these windows come with simulated divided lights in a 6 over 6 pattern?
    Do they open like a casement only?
    Do they tilt in for cleaning?
    Do they have any plastic/vinyl parts?
    Do they need storms?
    Do they have screens to fit?
    Are there choices in style and material of hardware?
    Is the outside and inside wood?
    What is the expected lifetime of these windows?

    And finally….how much do they cost?!

    We are in a window time crunch for a 40 + window house and would love a reply as soon as you can.
    Thank you!

      Simulated divided lights are possible.
      These windows are tilt and turn – which mean they swing in like a door, or tilt in like a hopper – all in the same window
      If you open them like a door – you can clean the exterior glass
      No vinyl/plastic parts in this window, except for some small plastic spacers at the drainage plane.
      No need for storms – the come in high performance triple pane glass
      Mosquito screens are a possible extra.

      Materials can be spruce or oak. Other wood by special request
      Inside and outside wood – the exterior is normally painted, inside is by choice
      Lifetime, if the windows are maintained/painted can be 25 year plus

      Cost? Please send us your drawings (info@foursevenfive.com) so we can provide a quote
      the PHI certified units will cost more of course and are higher performance, than the full wood version.

    This is exciting,what’s the skinny on lead time.

    What’s moderation?

    • Floris June 10, 2016 at 9:28 am #

      What we mean by moderate insulation values in your historic walls – is that by using higher performing (class A PHI certified windows). that you can reduce the amount of insulation in the walls (from for instance R-30 to R-23 and can still get similar EnerPHit performance in NYC, when compared to a non-certified triple pane all wood window. This can be required, as insulation masonry on the inside, makes the brick cold and adding too much insulation on the interior of the brick might make it too cold (even with INTELLO) – this is why moderate amounts of insulation, combined with the best (certified) windows can be a great combination when working on interior insulation of brick properties.
