Guardian Roof Efficiency

Saving you money on your heating bills

Our Guardian™ warm roof systems are fully tested and approved to all thermal and structural standards, a high performance insulated roof system comprising of a pre-engineered lightweight frame, two layers of rigid insulation board, internal insulated plasterboard, exterior grade plywood and a vapour membrane.

Altogether this creates a thermally efficient living space for you to enjoy, keeping warm air out in the summer months and preventing heat escaping in the winter saving the amount of energy required to keep the room at an ambient temperature year round.

LABC Approved

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™ solid roof is a strong, lightweight tiled roof and is fully approved by the Local Authority Building Control.

Thermal Regulations

To comply with part L of the building regulations 2010, all roofs to rooms (except those in unheated buildings) should be thermally insulated to a maximum U-value of 0.18 W/m²K.

Structural

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 an increased loading. The conservatory window framework must be assessed also and the new roof structure must be proven to be structurally sound.
