Hacker News用户正在讨论使用大猩猩玻璃建造房屋的潜力,并引用了《华尔街日报》的一篇文章。虽然这项技术拥有改进的隔热和节能效果,但评论者强调其成本远高于标准窗户,对于许多房主来说是一种奢侈品。一些人认为厨房和浴室的装修比更换窗户更具投资回报率,这表明需要激励措施来鼓励采用这项技术。 几位用户分享了他们更换窗户的经验,一些人发现这对于新建筑来说是一个可控的DIY项目。然而,其他人指出在旧房子中,特别是那些使用灰泥或非标准尺寸窗户的房子中,更换窗户会很困难,这可能会使项目变得昂贵且复杂。讨论表明,更换窗户的流行往往是由美学升级(例如改变窗框颜色)驱动的,而不是仅仅出于节能的考虑。用户一致认为,成本效益取决于个人的供暖和制冷费用。

    Using Gorilla glass for home building (wsj.com)

    It says “only 20% more than energy efficient windows” but those “energy efficient windows” are usually 50% more than the average quality window. Higher quality triple pane windows exist, and they are a luxury for most homeowners. It’s great technology, but relatively few people build or upgrade their house with the long term consequences in mind for these things. There’s a reason you get a positive ROI when you fix up a kitchen or bathroom versus replacing windows which is typically viewed as maintenance. There needs to be incentives for these upgrades to be adopted by home builders.


    > this glass is so well insulated, it actually creates warmth in his living room: It admits the radiant heat of the low winter sun but prevents conductive heat loss through the window


    Steve Jobs with a windows update? Very confusing


    This is a strange article. It portrays triple and quadruple pane windows as a new development, but they've been around for years.

    As far as I can tell, the only development here is the use of Corning's much thinner glass.





    As a home owner - updating / improving my windows is a luxury I very much wish I could afford. It’s hard to imagine being able to mess with the windows unless it’s with a newly purchased empty property.


    I've replaced windows before, and I'm handy but not a professional.

    Depending on the construction it's not super hard to pull them out and put new ones in, it takes about 20-30 min per window.



    Replacing windows is actually one of the easier DIY home jobs you can do. Hell of a lot easier than building a deck that a lot of people do. They are installed after framing and meant to be removed if they break. Removing the trim inside and outside will give you access to the fasteners holding the frame in.

    Usually, the hardest part is finding windows that fit and match your taste.



    That's true for relatively new construction, but for instance, I have a 100 year old house with stucco. Replacing my windows is a nightmare job. Whereas my back deck was a far simpler project


    Same here. We removed trim inside the house and it wasnt that bad, but I was just replacing the trim— not the windows. I could see that removing the windows would be a pain the ass very quickly. And it has already been done once.


    Finding the right size windows without having to go custom has proven to be nearly impossible. It's not a hard project but unless you are fortunate with window dimensions it is far more expensive than building a deck.


    naive question- couldn't you resize the hole in the wall to use a larger window pane?


    Mine are due to be replaced, and I’ll definitely keep my eye on this. But, if that wasn’t the case, I wouldn’t be running to replace windows before end of life.


    Judging by home owners around me it looks to be quite a popular change. As far as I can tell they're pretty much changing like for like (upvc with double glazing) without the energy efficiency upgrade. Changing from white to black frames seems to be the driving factor.


    Depending on your heating and cooling bill it could be cost-effective. The new windows are so much more energy efficient that you start to payback the insulation costs pretty quick.
