Ventilated ridge & hip system for Danbury Palace

Ventilated ridge & hip system for Danbury Palace

Protect Membranes Ltd has provided their Fulmetal Rediroll system for the Grade II listed Danbury Palace. This historic property was being converted into luxury apartments and in the grounds of the palace some twenty six new houses are being constructed to be architecturally in keeping with the historic main building.

The size and shape of the roofscapes presented many challenges for the contractors. In most instances, the use of traditional roof ventilation products could be used to alleviate the risk of condensation but the monoridge roof detail needed something special to meet the requirements of BS 5250 of 5,000mm2/m along their length.

The solution was Fulmetal Rediroll which offers a truly universal dry fix, ventilated ridge and hip system including use with monoridges. Brown Roofing Contractors Ltd were able to utilise Fulmetal Rediroll on the monoridges, cladding both the top edge of the slates and the vertical edge of the monoridge to provide a ventilated and weatherproof solution. The unique, universal fixing plates and screws provided consistent spacing between the monoridges whilst offering mechanical security.

Furthermore, the contractor added additional fixing plates and screws to the back leg of the monoridge providing a ‘belt and braces’ solution to further securely hold the ridge system in place. This was particularly important as the ridge line was some 12 metres above ground level.

Stuart Fisher, Contracts Manager at Brown Roofing Contractors, said:"Brown Roofing Contractors Ltd chose Protect Fulmetal Rediroll because having worked with Protect before, we knew that their Fulmetal Rediroll without a union bracket would suit not just the monoridge aspect of the roof, but all the ridge and hip requirements of the roofline. Another major benefit was that with additional fixings available, we were able to apply further mechanical security where required giving the roof full protection against all future weather elements."
