The Enlightenment: The Lamb Studios Stained Glass Newsletter

Issue No. 1, February 2014

Introduction

Welcome to the first issue of “The Enlightenment – the J&R Lamb Studios Stained Glass Newsletter”. Our goal is to inform our readers about the many aspects of stained glass windows. Technical articles about stained glass construction and maintenance, stained glass in the news, recent stained glass projects, and the history of stained glass will all be featured.

Energy Conservation and Stained Glass Windows – What is the Advantage of Protective Coverings?

The energy savings that can be achieved by covering a stained glass window is considerable. Stained glass windows can be covered with two basic types of material: glass or plastic. Probably one of the most widely used plastics are polycarbonates, sold under the trade name of Lexan manufactured by General Electric. They guarantee the product is unbreakable for three years. This product will yellow over time, so this is a major consideration. Also available are Plexiglas, acrylite, and lucite, which are plastics that can crack upon impact but are seventeen times stronger than ¼”plate glass. They will remain clear for a much longer period of time.

Plastics are easier to work with than glass, but they tend to have a slightly wavy appearance and sometimes a purplish cast when installed. Over time they will scratch and accumulate dirt if not properly cleaned and maintained.

Glass, which was used exclusively until about forty years ago, is ¼” thick and is cleaned for the most part by rain and wind. It will withstand air pollution much longer, will not scratch, and can be cleaned very easily. Its great disadvantage, of course, is its relatively easy breakability.

The Solution

Most studios today recommend using laminated architectural glass. With a polyvinyl butyral center layer bonded between two sheets of glass, laminated glass combines the clarity and the clean appearance of glass with the damage protection afforded by plastics. Laminated glass may crack upon impact, but will break safely without glass splinters and will not allow flying objects to penetrate to the stained glass behind.
