15% annual energy savings with LLumar solar control window film


The Carroll County Courthouse is a classic “town hall” building that stands in a square in the middle of the town of Mount Carroll. Built in the early 19th century, the courthouse has served the town and community for nearly 200 years. Its large courts and chambers were often too cold in the winter and hot in the summer. The government wanted a cost effective solution to improve energy savings.


When the 12,000-square-foot building was remodeled, Johnson Controls, a global Energy Services Company (ESCO), was contracted to audit energy consumption and prepare a recommendation for
improved efficiency. LLumar Neutral Series N-1020B was recommended to be installed on all windows and glass doors because of its superior heat control properties.


Professionally installed by the local LLumar dealer, LLumar window film reduces excessive summer solar heat gain by 73% and  contributed 15% annual savings in heating and air conditioning costs. The installation of LLumar neutral window film reduced glare and provided superior ultraviolet (UV) protection for interior furnishings and the occupants.

LLumar window tint is professionally installed by trained technicians and is backed by a lifetime limited manufacturer’s warranty.
