Health and wellbeing

Hunter Douglas contributes to sustainable buildings through aesthetic solutions that enhance comfort and save energy. Promoting health and wellbeing of their occupants is arguably the most important function of buildings. Buildings are not constructed just to be energy efficient. Our shading solutions promote the use of healthy daylight without the hindrances of glare and thermal discomfort. Our acoustic ceilings are a key element in the provision of acoustic comfort.

Sound materials

Environmentally sound materials are key to sustainable buildings. Our strategy is to pick materials that have good environmental properties to start with. Many of our products are made of aluminum produced in our own smelters. We’ve optimized our processes to use up to 99% of recycled content to produce the right alloy for our products. Our wood is FSC certified and we embrace the Cradle to Cradle principle in our product development.

Energy savings

Reducing the energy use of the total building stock is key to the prevention of global warming. Most modern office buildings use more energy for cooling than heating. Effectively managing the solar energy that passes through the transparent part of the façade is a key strategy in the prevention of overheating in both old and new buildings. Our high performance shading solutions bring substantial energy savings, while at the same time promoting health and wellbeing.

Corporate Social Responsibility

Keen on Green is an important company-wide initiative to reduce energy consumption, water usage and our overall carbon-footprint. We embrace the ISO 14001 framework to actively manage our Keen on Green objectives. Hunter Douglas and its employees actively support the communities in which we live and work, as well as those on a more global scale. Business is people. We pride ourselves on our worldwide network of experienced, intelligent, passionate and creative people that have consciously chosen Hunter Douglas as their employer.
