Cembrit’s comprehensive range makes stocking and fitting the correct ridges for fibre cement roofs simpler.
Available immediately, the ridges weigh less, and are easy to cut and fix, making them superior to mortar bedded, concrete, or clay alternatives. In addition, is the lower weight per linear metre ratio, equalling smaller footprint, making Cembrit ridges easier to store and a more cost effective choice.
Cembrit fibre cement ridges do not require electric power for cutting and dust suppression, and are easy to install. Installation is not dependent on getting the correct mortar mix, nor having to wait for dry weather, as it can be fixed with ‘sela’ type screws.
Ged Ferris, Cembrit marketing manager said: “Accessories should not be an after-thought, they are an integral component of the roof, contributing to its functionality
“Increasing demands for energy efficiency, through improved levels of insulation, means ventilation at roof level becomes more crucial. Particularly with tight fitting roof coverings like fibre cement slates, it is necessary to remove moisture carrying warm air from voids in the roof space. The most efficient solution will incorporate inlets at the eaves with outlets along the length of the apex.
“Cembrit has developed a continuously ventilated ridge, to cope with typical roof pitches as well as helping the roof design comply with the latest version of BS 5250. For tricky ventilation problems, where there is no clear airpath from eaves to ridge, Cembrit has developed low-profile vents for use on the roof slope. These are unobtrusive and can also be used as terminals.”
