closed cell foam board
Closed cell foam board represents a revolutionary insulation material engineered for superior thermal protection and moisture resistance. This versatile construction material features a unique cellular structure where individual cells are completely sealed off from one another, creating an impermeable barrier against water, air, and vapor. The manufacturing process involves expanding polymer materials like polyethylene or polystyrene into a dense, uniform structure that maintains its rigidity while remaining lightweight. Each closed cell contains trapped air or gas, providing exceptional insulating properties and contributing to the board's overall R-value. The material's structure makes it particularly effective in preventing heat transfer through conduction, convection, and radiation. Commonly available in various thicknesses and densities, closed cell foam board adapts to diverse construction and industrial applications. Its robust composition ensures long-term performance in challenging environments, from subflooring and wall insulation to marine applications and cold storage facilities. The material's inherent resistance to moisture absorption significantly reduces the risk of mold growth and material degradation, making it an ideal choice for both interior and exterior applications where moisture control is crucial.
