The Heat and Frost Insulators are the
original green energy specialists
conserving energy to our customers in Northeast Illinois and Northwest Indiana since 1899.
As the Chicagoland area becomes a leader in green design, developers are utilizing new types of building materials, lighting and heating, and cooling and ventilation systems to make their properties more energy efficient. In fact, a recent report found that green buildings use an average of 36% less energy than conventional buildings.
When it comes to building green, commercial developers should look to the Heat & Frost Insulators and their affiliated contractors as an essential partner in fully realizing green building goals. Insulation of mechanical systems is a fundamental element of green design and building. Poorly designed and installed insulation will undo all the benefits of an otherwise green building.
Through a partnership with the Illinois Regional Insulation Contractors Association (IRIC) and it’s member contractors throughout Illinois, Heat and Frost Insulators has been vital to the energy efficiency and life safety infrastructure of our region.
