They were boxy, and they didn’t look like the original. They didn’t have the same kind of detailing as the original windows. Plus, the glass was failing and the windows were leaking air because the weatherstripping had failed,” he explains.
The aluminum replacements were removed, revealing the original wood window frames, which were then restored using restoration epoxies and replicated wood parts. Gentleman and company used an original complete wood window that still remained in the building as the basis of design for replicating new sashes with acetylated wood, which will last well beyond the glass.
—a matter of great importance and potential liability for engineers of record (EORs), who, in accordance rcs data with several building codes and the UL Fire-Resistance Rating Directory, are responsible for identifying and approving the use of such designs on a project. Understanding which designs are restricted, and calculating the load restrictions, can be a complex process.
