info on building custom skylights

popawheelie | Posted in General Discussion on October 8, 2009 06:05am

I have an area outside that i would like to put inexpensive self built skylights in.

They don’t have to be waterproof as much as they would be inexpensive.

It’s a walkway between two sheds I built.

I wanted to have the plastic bent to form a half or part of a cylinder so they would be strong and shed water and snow.

Is there a place where I could buy the frames and plastic for this?

Or is there a place that could make them?

thanks!

    Just cut a hole then.

    What kind of roof & how steep?

    A sheet of plexiglass might work.

    If you can't design, build, and install these yourself, then your need for them to be inexpensive will go unfilled.

    Like seeyou said, maybe a sheet of plexiglass. But make sure you give it enough support to handle the snow load. Plexi is bendy and generally weak.

      Thanks Piffin. They aren't cheap. But I probably can't get them for much less.

      I have been looking on craigslist for skylights.

      The problem with used ones is they won't match eachother. "There are three kinds of men: The one that learns by reading, the few who learn by observation and the rest of them have to pee on the electric fence for themselves."Will Rogers

      There is some galss for sale.

      "I have 8 sheets of tempered glass for sale. Dimensions are 42" by 67" 1/2 inch thick "

      The price is low. $50 for all eight.

      Would it be a good idea to put 1/2" tempered glass horizonal?

      What kind of snow load could it handle?

      If a stone or hail hit it?

      Does tempered glass shatter into small pieces? I can't remember.

          I'm assuming if they are tempered there will be an etched mark in one corner.

          Just making sure before I go buy them.

          I'm going to measure up the area and see if they will work.

          edit: I just measured it up and I can make the size work. I will need one made up to fill one space though.

            Yes, there is a mark in the corner. I believe that they could also be laminated or safety glass. Seller might not know the diff. It has a re-inforcing plastic betwen two sheets of tempered making it thick and that holds it together better in ccase it does break.U-tube had lots of different tricks and tests and idiots showing temnpered glass, but a lot of it was safety glass that I was seeing.
            Brought back memories of when I walked into a sliding glass door once and I got to watch it bounce back and forth 2-3 inhes without ever breaking.Most used tempered like this is from sliding glass door replacements going back into the used market, sometimes sealed insulated for greehouses, and sometimesthey were separated because oif broken seals. Those can have an etched surfacce that you can't fully clean again.For my money, I would buy a skylight if I were you, depending on just what the roof situation is. Building a urb and flashing is easy for me - done a thousand of them, but it takes time

            Thanks for the advice. I think I'm going to get them.

            At $50 it hard to pass up.

            I've built curbs for skylights a long time ago.

            This is different. It will be between two sheds I built outside so if it leaks it's no big deal.

            I'm trying to get a greenhouse effect to capture some of the heat.

            I'll take pictures of my progress and explain when I do it if it comes out right.

            If it doesn't turn out nice I'll bury it. ; ^ )

            It doesn't make sense if they are 1/2" thick if they came fron sliding glass doors.

            They are single pane 1/2".  

            Maybe a comercial application.

            The picture shows they still have those little square pads on the glass.

        I got an email this morning that he sold them. Should have moved faster.

        It is interesting that the glass showed up just as I was realy looking into this.

        I have a question.

        Since i missed this glass I'm thinking I can get some from sliding glass windows.

        Are all the sliders going to be tempered glass? I assume so.

        And typically, what thickness of glass would they be?

        I will be orienting the glass horizontally and the span is about 45".

        There are a fair amount of sliding glass doors in Craigslist. "There are three kinds of men: The one that learns by reading, the few who learn by observation and the rest of them have to pee on the electric fence for themselves."Will Rogers

          We built a bunch of "solar panels" in the 70's using single glazed large panes of glass that were rejects from some place that was making sliding doors. The customer got them basically for free he just had to arrange shipping.

        2. MikeSmith | Oct 10, 2009 03:49am | #17

          the problem with most sliding door panels is they are designed to be installed vertically.... when they are installed out of verticsal it stresses the assembly and you get   a lot of seal failures

          single glazed  solar collector glass is typically 3/16 or 7/32, tempered in all cases...

          my guess.... you will get a more reliable install with single glazing, the thicker , the better

          btw.... in your situation.... site-built skylights make sense.... but most of the time i would never  use a site-built.... they usually fail
