ICF Builder Magazine features Washington Street offices project on front cover of Nov/Dec 2016 publi

Groen Construction made the cover of Insulated Concrete Form - ICF Magazine! Check out the website to read the article and learn more about the award we received for our 3-story Washington Street Offices project. Our building was designed to showcase the beauty, cost-effectiveness, energy efficiency and comfort of ICF. Completed in May 2014, the average monthly energy use for the first full year of operations, including potable water heaters ran $431!

Insulating Concrete Forms (ICF) are the future of the building industry. Popular for both residential and commercial ICF construction, ICFs create homes and businesses that are energy-efficient, fire-resistant, sound-proof, and durable. Properly constructed, they are tornado and hurricane-proof, and stand up to earthquake, fire, and other natural disasters equally well.
