Since 1990, Perimeter Systems has provided Designer Series Cornices for churches, universities, financial institutions, municipalities, and stately homes throughout the United States.  Whether new construction or a historic renovation, Perimeter Systems’ innovative “interchangeable” cornice trims allow you to design beautifully sculptured cornices limited only by your imagination.

Predesigned Cornices
We offer 15 predesigned cornices with all the details worked out for you.  These cornices may be modified to suit your building’s eave condition and have been detailed with traditional wood support framing as well as more contemporary steel framing.  Our framing details are suggestive in nature and are provided only as a guide to your design efforts.

Interchangeable Profiles
Our cornice trims and mouldings are available in various sizes of concave, convex, quarter round, half round, and box shapes.  Many of these trims are designed to interchange with one another where you can mix and match to your own taste.

Design To Simulate Stone Cornices
In addition to our cornice trims being interchangeable they are designed to simulate stonework.  This is achieved through the use of “expansion reveals” at the vertical cornice joints.  This expansion reveal consists of a concealed splice “back-up” plate which allows a space between the adjoining cornice members.  This small (3/8”) space creates a light shadow line at the vertical cornice joints and when properly aligned simulates stonework.
