SIGMA

Sigma are stainless steel design gravity shutters designed for mounting on house facades, walls or plaster, for air extraction especially from high-capacity hoods and fans. The Sigma louvre shutters with circular connections are insulated and tight, designed for higher pressure fan applications and recessed mounting. The Sigma residential shutters feature a unique patented design.

The square grille plate is fitted with two louvres, a dripcatcher and a secondary insulated butterfly damper in the circular spigot in the wall. This combination of non-return dampers and insulation ensures a high airtightness of the duct as well as a reduction in heat loss after automatic damper closure. The air dampers with their modern design are made of stainless steel and are also available in black and white. Patent N°: 004028397-0001.
