"The #1 way to reduce your home's heating and cooling costs is through proper insulation and air sealing."

- U.S. Department of Energy

 Over the years due to lower fuel costs and lack of awareness, construction building codes allowed insufficient levels of insulation to be installed in new construction. It is common for older St Louis area homes to have insulation levels that are drastically lower than what we know now to be required for ultimate energy savings, air quality and comfort. Adding insulation and air sealing key areas of your home will help contain heated or cooled air to the conditioned space for recapture leading to less work and results in longer life for your h.v.a.c system. It is also common for customers to experience less fluctuation from temperatures from room to room and floor to floor.

St Louis Insulation's certified technicians utilize the latest building science techniques, experience and equipment to recommend common sense solutions for customers seeking to save money on their utility bills, be more comfortable in their own home and to do their part for the environment by helping to reduce our dependency on fossil fuels.
