Glass panel mount to wooden Marvin awning, spacers or drill?

lucamajukia | Posted in Energy Efficiency and Durability on

I’ve got eight, twenty year old wooden awning windows that need regular maintenance. I’d like to extend this interval by adding a glass panel to the outside of the sash. In order to remedy the condensation issue I could drill the panel to allow moisture to escape – like airplane window weep holes, ~ 1/32”.  Another option would be to space the panel with a small “o” ring or nylon washer at each attachment point.  I’m planning on drilling four holes and attaching with stainless pan heads and nylon washers.  

My primary concern is to mitigate the maintenance issues and secondarily to get better performance.

    Hi Ben,

    What maintenance do you hope to avoid with the extra glass panel fastened to your windows? I'm not sure I understand.

    The wood sash needs regular attention in the form of scraping/sanding and painting. I thought I would try it out on a my worst (west facing) sashes and see how they perform before committing to the whole lot.

      Why not install more common storm windows? They will offer some protection and are known to improve performance, when installed well.

    I just replaced storms on double hung windows and that got me thinking about these awnings on the second floor. The double hungs have been protected by storms and haven’t needed new paint in 20 years. I’d like to give similar protection to the awnings.

      I get it. And you want to leave them on year round for protection. Where storms would have to come off the awnings if you want to open them in the summer. Well, please report back and let us know how it works out.

    Will do, I’ll try the spacer approach and only caulk the sides and top to allow some air movement through the bottom.
