WindowMaster is a manufacturer of window automation hardware and controls: it designs and manufactures actuators for nearly every window type and controllers that manage window automation and connect windows to the building management system. Its sensors measure room temperature, CO2 level and humidity, and its actuators and controllers carry its MotorLink communication technology.

Natural and mixed mode ventilation produces fewer carbon emissions than purely mechanical ventilation, and its ductless strategies can be added to existing buildings. WindowMaster supplies pre-engineered actuators, mounting brackets and controls for standard storefronts and curtain walls that glazing contractors choose for window automation, and it provides digital models for coordination with architects and general contractors. Natural and mixed mode ventilation is widely adopted in the UK and EU.
