When Kirkby Market in Liverpool was transformed into a fully covered market, a watertight day lit street between the market stalls was required. The developers asked Whitesales to rise to the challenge and the Em-Vault polycarbonate multiwall barrel vault system was specified as a solution.

Whitesales Em-Vaults have provided Kirkby Market with an unobstructed glazed area allowing natural daylight to fill the market street. The units also incorporate natural ventilation between the Em-Vault barrel vault system and the market below.

The project architect said "We are really pleased with the rooflights at Kirkby Market. We appreciate it has not been the easiest scheme and are delighted with the end product."
