Energy conservation

Commercial, public and industrial buildings account for nearly 20% of carbon emissions in the China. Sealing the gaps around doors is one of the most cost effective ways to save energy in your building. Direct from the China’s largest brush strip manufacturer, Bursten closes gaps around doors and openings on all commercial, industrial and residential buildings.

Uncontrolled airflow through gaps around entrance doors, windows, access floors, elevator entrances causes loss of heating and cooling energy and significantly reduces a building’s thermal performance. Sealing with Bursten helps to maintain air conditioned environments, keep foyer areas clean and prevent discomfort for staff, customers and residents alike.
