Polycarbonate rooflights for West Kirby station

Polycarbonate rooflights for West Kirby station

Whitesales has provided there polycarbonate Em-Vault continuous barrel vault rooflights as part of refurbishment works at West Kirby railway station. 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. After the initial roof survey, Whitesales 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 the GRP T-Vault rooflights: they can readily incorporate roof access. This was essential for future maintenance, so Whitesales specified four single-skin Em-Vault rooflights, one with manual opening supported by gas struts.

Pre-manufacture site visits allowed Whitesales to take precise measurements, working around the extant skylights, and they provided detailed curb construction drawings so the contractor could construct the curb correctly. Whitesales also added external lateral bars to increase the Em-Vault’s non-fragile rating to ‘man-safe’.
