Incredibly energy efficient

Fully tested and approved to all thermal and structural standards, the Guardian™ Warm roof is a high-performance insulated solid roof system. Comprising of a pre-engineered lightweight aluminium frame, exterior grade plywood, complete with a breathable membrane. Two layers of rigid PIR insulation, then finished off internally with insulated plasterboard. All together this creates an extremely thermally efficient living space; keeping the warm air out in the summer and preventing the heat from escaping in the winter thus saving the amount of heat energy required to keep the room at an ambient temperature.

Building Regulations

Only since October 2010, has it been officially possible to put a solid roof onto a conservatory or porch.

In August 2013 the Local Authority Building Control (LABC) released a circular containing some basic guidelines relating to Building Regulation Legislation which apply to the replacement of a translucent roof (made from glass or polycarbonate) onto a conservatory or porch with a solid roof.

The Guardian™ Warm roof was the first of its kind to be fully approved by the Local Authority Building Control. Now working in partnership with LABC to ensure ease of approval when submitting your applications to your local building control offices.

Thermal Regulations

To comply with part L of the building regulation amendments in 2022, all roofs to rooms (except those in unheated buildings) should be thermally insulated to a maximum U-value of 0.15 W/m²K (English regulations)


The building as a whole must be structurally sound. Any alterations that affect the original structure must be carefully considered. The foundations must be checked to ensure their suitability for any increased loading. The conservatory window framework must also be assessed and the new roof structure must be proven to be structurally sound.
