Jargon Buster

Building roofs is quite technical and so sometimes we use technical language. Sorry about that. However, to keep things simple we've designed a manual to explain and translate many of the commonplace words and terms used in the conservatory industry.

Each reference includes a list of alternative words ("also known as"), a full description of the product/component and, where relevant, a picture to illustrate its relevance.

To find the explanation for your term simply browse alphabetically below.
