Just a little over a mile from our Eichler neighborhood is the headquarters for renowned window manufacturer Blomberg Window Systems. Blomberg specializes in a proprietary line of aluminum windows and doors.
We are in the middle of a renovation at our other midcentury house (circa 1961) and I can vouch these windows are the best. We chose four three-pane Series 1400 casement windows (two with hoppers and two with transoms) and a slider -- all with LoE2-172 glass and clear anonized frames. I have really been impressed with their solid quality and smooth operation.
Please don't put cheesy white plastic vinyl windows on your midcentury modern home. You and your house deserve better. This concludes our public service announcement.
