The Market Hall is located in the centre of Stockholm and houses food stalls and restaurants. Wingardh created a large hall with a massive ceiling height of 11 metres. Daylight penetrates the space from the short façades and the six triangular roof lights.

The building interior has an exposed timber structure consisting of a latticework of glulam beams resting on columns of cross- laminated timber. The choice of wood had several advantages. The relatively light weight of the structure meant that a minimal concrete foundation was possible saving time and money.

It is also a renewable resource with a negative carbon footprint. The issue for Gert Wingardh and his team was to be able to provide a durable, Group 1 equivalent clear fire rating to the timber surfaces in a non-conditioned environment that houses food outlets, kitchens and hundreds of people every day.

Fireshield TimberClear1FR + Top Coat (Matt) was their coating of choice, used on the timber glulam and plywood linings it provides the maximum Group 1 equivalent rating. TimberClear1FR allowed the Architects the freedom to design with a natural resource, timber.
