Conservatory walls consist largely of glazed elements including windows and doors that
may include structural mullions or may be strengthened with internal structural
reinforcement inside hollow sections. Modern conservatories are likely to be marked in
accordance with BS EN 14351-1:2006 + A1:2010.
The Guardian Roof System is designed to be of similar weight to a glass roof of equal
size, so it follows that the existing glazed walls, if correctly specified for a the original
glazed roof, should be capable of supporting the replacement Guardian Roof System.
It is the sole responsibility of the installer to establish the structural suitability of the
existing conservatory wall system, to establish the location of any structural or
reinforcing elements, and to ensure that the Guardian Roof System is fixed to the existing
structural elements so that gravity and wind loads are transferred safely through the
existing walls to the conservatory foundations.

The following guide has been created to assist in the fabrication and installation of the
Guardian Roof. Please note that each roof is individual and will be fabricated to suit
various shapes and sizes.
Each roof supplied will be accompanied by a roof layout plan and this guide.
Your fabricator will be available to provide installation technical support.
Roof Layout Plan
Please refer to the roof layout plan prior to commencing installation. It is very important
that the roof fits the windows layouts and that all the windows are fully reinforced. All
components are numbered to match the roof layout plan for ease of installation.
