The HR40 Family

Unparalleled Quality

The HR40 Window family has a fit for every space in every house. With the help of HR40, every room can offer its occupants a bright, welcoming and comfortable space, from the living room, to the master bedroom.

All HR40 products are manufactured with high quality, double-pane glass, insulated with a proprietary heat-mirror film and Krypton gas for the best temperature retention ever seen in a window. We carry all standard and custom window sizes, so we guarantee that we have a window or door to fit your home.

Every HR40 product is engineered with a commitment to quality in mind. Each member of the HR40 family has unique characteristics that will suit your home differently. HR40 bays will fill up an entire wall, while HR40 hopper or awning windows make great use of small spaces. However all HR40 products share some of the HR40’s premium quality components, including:

  • Unified Construction

    All HR40 Products are fully unified – all parts are fusion welded at the factory. Frames and sashes have no visible seams, meaning that your products stays insulated and sealed, for a longer, more efficient lifespan.

  • Intercept Spacer

    The proprietary “Intercept” spacer, HR40 products create a unique thermal barrier on all their glass surfaces. This better insulates your glass, resulting in less condensation forming on the inside of your windows, making for a more comfortable home and a longer-lasting window.

  • Krypton Insulate

    All HR40 glass is insulated with Krypton gas, rather than the traditional Argon Gas1. Krypton is a denser, more insulating gas, and works in tandem with our suspended heat-mirror film to give you a more serious insulation rating.

  • Heat Mirror Technology

    Proprietary suspended heat-mirroring film 1 works in conjunction with the dense, Krypton gas that fills all HR40 windows to give you a window that insulates more like a wall, keeping your home cooler in the summer, and warmer in the cold winter months.

What Is "Heat Mirror" Technology?

Heat Mirror Technology is a proprietary method of suspending a piece of insulatory film between two or more panes of glass, to create a smaller, more easily insulated space. This space allows dense gasses, such as Argon or Krypton to better insulate against UV and IR heat transfer from one side of the glass to the other, while simultaneously allowing the visible light of the sun through, for a brighter, more welcoming space that achieves optimal comfort and efficiency.
