West Kirby railway station’s 1930s platform canopy was long overdue refurbishment. Built of concrete and timber, and featuring skylights, it had begun to leak, while spalling saw small pieces of concrete falling on the platform. Whitesales were brought in by Briggs Amasco, Network Rail’s roofing contractor, to design, manufacture and install a series of non-fragile rooflights for the 900sq m replacement roof.
The greatest challenge was working in a live station environment, with no changes to train timetabling. Minimising disruption for staff and commuters was critical, and as such there would be just one access point to the roof. No edge protection was possible; every operative would need to be harnessed and work using a safety line system. The programme also demanded that we prefabricate our replacements before the existing skylights had been stripped away, and carry out installation using a strictly timed schedule.
After our initial roof survey, we specified bespoke polycarbonate em.vault continuous barrel vault rooflights. They’re compatible with the chosen Sika Liquid Plastics roofing system and have light transmission of up to 88%. The standard mill finish frame would keep costs low and blend with the canopy's concrete finish.
em.vaults offer one significant advantage over our GRP T-Vault rooflights: they can readily incorporate roof access. This was essential for future maintenance, so we specified four single-skin em.vault rooflights, one with manual opening supported by gas struts. Pre-manufacture site visits allowed us to take precise measurements, working around the extant skylights, and we provided detailed curb construction drawings so the contractor could construct the curb correctly. We also added external lateral bars to increase the em.vault’s non-fragile rating to ‘man-safe’.
