Identify window mfg. to replace sash

This information doesn't identify the manufacturer. Usually, it is not necessary to know the manufacturer to fix a sash, and in fact, you usually do not need to replace the whole sash. That can be expensive and very difficult. SWISCO, being a hardware retailer, doesn't handle glass or window sashes.

An easier alternative is to salvage the frame by bringing it to a local glass shop. They can remove the glass unit whose seal broke, and replace it with a new glass unit. Good luck with your repair!
