I own a landmarked historic home and am gearing up to restore/replace the windows. The current, original windows, are single hung, single glazing weighted sash’s. Before I purchased the home (and probably before it was designated a historic landmark) the original, removable, storm windows were replaced with modern storm windows with screens. These function great as you can slide open the storm window from the interior and still have the screen in place, but they are unsightly.

It’d be easy enough for me to replicate the original sash’s and storm windows, but I was hoping to increase their functionality. For instance, I refuse to remove and store the storm windows every summer. I would also like screens on all windows (again, I don’t want to store these in the winter to swap with the storm windows- the house is BIG and the second story is HIGH, and I don’t do ladders > 6’).

I was wondering if I could incorporate some modern features into my replica’s. For instance buying double glazing’s to replace the single panes, and incorporating some type of weatherstripping. I hope these two additions would eliminate the need for a storm window and therefore allow the permanent placement of a screen.

Any thoughts, guidance, and lessons learned would be appreciated.

Thanks

WSC.

Have you checked with the regs regarding upgrades to a home on the historic register? Might wanna do that before you make any changes.

Yes, of course. I am in regular contact with our landmark preservation society. This is why I am only considering “invisible” modernization, like double instead of single glazing and incorporation of a gasket or weather pile.

Have you specifically checked codes on double pane (glazing) windows?

Have a family member with historic house, that wanted to remake window panels like you. Problem is that double glazing is not invisible and was not period correct for house; and was ‘banned’ by their preservation codes.
Even replacing the single pane glass with newer coated e-glass to reduce thermal losses was not allowed.

Suggest you talk to a couple of custom window companies near your historic area. They deal with these issues everyday, and have access to special seals/gaskets used to improve old window sealing.
Historical rules can be difficult to bypass. Best Luck.

I don’t have a direct answer to your question, but can offer a point to consider: A big, multi-story home doesn’t welcome the idea of swapping out glass and screen inserts like you said. You’ve been in house awhile, I assume. Is it even somewhat tenable to do that for just those windows you do want to open in the spring and fall, evenings over the summer, etc? A handful of change outs vs. dozens (?) might not be that bad.

The suggestion above to find those in your area that have already learned the lessons you’re facing is a good one too.

Good luck on your effort.

If you switch to double pane glass the windows will be heavier so the sash weights will need to be changed. When I made my own I melted lead into fence pipe to get the weight correct. I also used bronze weather stripping in my double hungs. I purchased a lot of my window hardware here http://kilianhardware.com/tradwinhar.html
