Insulating closed-section joist cavities with closed-cell spray foam is an excellent choice for the efficient thermal insulation of buildings. Closed-cell spray foam fills the traditionally hard-to-reach areas between joists, creating a homogeneous insulation layer. This material perfectly adapts to the shape and size of the joist cavities, minimizing thermal bridges and reinforcing the building’s energy efficiency.

Thanks to the excellent thermal insulation properties of closed-cell spray foam, it effectively reduces heat loss in winter and prevents excessive temperatures in the summer. The closed-cell structure, by efficiently repelling water and vapor, protects the building structure from moisture, contributing to long-term durability and preventing the formation of mold or fungi.

This insulation solution maintains its effectiveness over time and is easy to apply, curing quickly. Insulating closed-section joist cavities with closed-cell spray foam not only offers advantages in energy savings but is also an outstanding choice for enhancing internal comfort, extending the building’s lifespan, and supporting sustainable construction practices.
