    Hi Jack,

    Do you know of any place you can buy glass that lets in the full spectrum of the sun? Is this even possible????

    These are some links to the type of plexiglass mentioned on this page

    I tried searching for UV permitting glass windows when I saw the thread and didn't get good results, so thanks for posting what you did. Now if people on the forum read John Ott talk about UV permitting glass we know what a modern version of it is.

    Boron nitride.

  5. Can't find it Boron Nitride in use as a Window material except for Microwave Oven windows... seems pretty cutting edge.

    Equipment in high-heat environments
    Its exceptional resistance to heat lends the compound to a wide variety of applications involving extremely high temperatures. Hexagonal boron nitride is being used to improve the lubricating properties of rubber, plastic, alloys, and ceramics.

    In the case of plastics, inclusion of a BN component provides lower thermal expansion. It may also be integrated into semiconductor substrates and microwave oven windows.

    Boron nitride is an effective component of reaction vessels and crucibles because of its thermochemical properties.

    I've wondered the same thing? I would love to get a skytube skylight that has no glass. I would have no issues climbing on the roof to open and close it by putting some sort of cap or cover over the opening. Those things reflect a ton of light into the house. Right now I have a mirror outside that I pivot with the sun to reflect more light into my house, but my door is left open. I've also thought of making inserts for my door, window, or car window made of polypropylene plastic. It's the same plastic used for my greenhouse. I'm sure the plastic blocks some spectrums of light, but my understanding is it lets UV light through and I'm sure it blocks far less red and IR than glass.

    Thanks for asking this. I was just about to. So I can ride with my visor up on my motorcycle sometimes.

    Thanks for posting. I work as an Optometrist and have a window in the consulting room which is rare. I was looming to change it to a full spectrum permitting plastic/acrylic. Alternatively I have
    To chsnge it to spmething I csn open vs fixed as it is now. I shall look at the links.
    Any input would be appreciated.
