Spray foam insulation is a modern insulating solution that expands upon application, forming a continuous barrier against heat and air infiltration. Comprising two components–isocyanate and polyol resin–when mixed, the substance rapidly expands, filling cavities, gaps, and cracks.
It comes in two primary types: open-cell, which is lighter and more flexible, and closed-cell, denser and offering higher R-value per inch. Besides excellent thermal resistance, spray foam creates an airtight seal, enhancing energy efficiency and indoor comfort. Its moisture-blocking capabilities also reduce the risk of mold and mildew.
While the upfront cost is higher than traditional insulating methods, its efficiency can lead to significant savings on energy bills. Given its adhesive nature, professional installation is recommended. This type of insulation stands out as an effective, long-lasting, and versatile insulator for various construction needs.
