In Cornwall, New York, contractor Jon Beer is working on a gut remodel of an old home, showcasing a strategic use of spray foam insulation for energy efficiency and comfort. Through this project, Beer sheds light on the importance of spray foam insulation in retrofitting existing homes that were not originally designed with energy efficiency in mind.
To address the challenge of different construction types in old and new sections of the house, Jon combines open-cell and closed-cell spray foam. Closed-cell spray foam is chosen for its high R-value per inch and built-in vapor retarder, which is crucial for the older, less sealed wall assemblies. The use of closed-cell spray foam ensures that the insulation is robust and durable, providing an airtight seal that prevents air leakage and reduces heat loss. Moreover, it offers excellent moisture control, preventing mold growth and improving indoor air quality.
Jon argues that retrofitting existing structures is the most efficient and lowest-carbon approach. By choosing to retrofit rather than build a new house, the carbon footprint of the original construction is acknowledged, making the overall impact more sustainable. He praises the versatility of spray foam, noting how it can air seal and insulate difficult-to-reach areas, thus enhancing the structure’s building envelope.
Retrofitting old buildings with spray foam insulation offers a tailored solution for varied construction types. Beer’s emphasis on sustainability and efficiency highlights the advantages of retrofitting over new construction, making the most of existing structures in an environmentally conscious manner. The combination of strategic insulation choices and precision application techniques ensures a comprehensive and effective retrofit, enhancing both energy performance and comfort. The adaptability of spray foam insulation shines through to efficiently and effectively remodel older homes.
