La Filature is a modern, energy efficient office building facing the headquarters of the Matmut insurance headquarters in Rouen, France.
The design choices were guided by the owner’s desire for Passivhaus certification, which sets very low energy consumption targets. Another example of the building’s sustainability priorities: it boasts a 30cm thick vegetated roof.
The project’s glass façades consist of triple glazing (some elements of which are curved) with solar control that also regulates the lighting. The skylights, located in the heart of the complex, and the large central atrium distil the natural light in all the floors, ensuring the building is cooled naturally.
Three Guardian Glass products were selected for the building: Guardian SunGuard® eXtra Selective SNX 60/28, a solar coated glass that provides the ideal balance between high light transmission and low solar factor, with outstanding thermal performance. Natural daylight is maximised whilst reflecting the optimum amount of solar heat away from the glass, helping to keep occupants comfortable at all times.
Guardian SunGuard SuperNeutral™ SN 70/37 was selected for its beautiful, neutral, transparent appearance with low reflection, consistent colour, high solar protection and high light transmission. Guardian ClimaGuard® Premium coated thermally insulating glass was also selected for its high thermal insulation, neutral appearance and high light transmission.
