Andrew M. Kerns, Ranieri & Kerns Associates, LLC. – Bryn Mawr, PA
I have been building quality homes in the main line for over 15 years. We use N.G.I. for all of our spray foam and specialty insulation needs. With the ever increasing importance of indoor air quality and energy efficiency, it is good to have a partner like Kirby Slack who totally understands the complexities of R- value, perm ratings and dew points. Our company often refers our clients, building inspectors and other homebuilding professionals to N.G.I. when codes conflict with up-to-the-minute science, trade publication information or common sense. He is a respected industry expert.
