When choosing the type of spray foam insulation for your building, you can either go with open-cell spray foam insulation or closed-cell spray foam insulation. Each has its benefits, so it all comes down to understanding what your surface needs. This article will focus on the predominantly endorsed closed-cell spray foam insulation.
Closed-cell spray foam insulation is the spritz application of low expanding plastic on your building surface to protect it from moisture and air. This type of insulation is common on roofs, pole barns, attics, rim joists, and crawl spaces.
How Closed Cell Spray Foam Insulation Works
Closed-cell spray foam insulation uses its dense cellular structure to provide building insulation. The dense cellular structure means a higher r- value (resistance value), hence better insulation.
The working of closed-cell spray foam is relatively simple. When applied to a surface, the closed-cell spray foam hardens. The air within is trapped in bubble form as the spray foam sets, creating an impenetrable barrier against outside agents.
What Closed Cell Spray Foam Insulation Has to Offer
Owing to its dense cellular structure, it takes a longer time for the agents of wear and tear to make it past the insulation to get to your building, thus giving your property long-lasting protection.
Closed-cell spray insulation works well even in smaller spaces like vans and smaller homes. Given its low expansion rate, its bubble cells will not easily rupture on expansion.
Closed-cell spray foam insulation prevents moisture seepage as it establishes a strong bond. For the roof, it hinders rainwater from seeping through to destroy the ceiling boards and other structural components of the house.
During floods, it also provides a seal for walls and floors that preserves their structural integrity long after the water subsidies.
Mold and Mildew Control
Because closed cell installation does not allow for moisture condensation around the building, it hinders the growth of bacteria. As a result, the damp flourishing mold and mildew cannot appear.
What Is Closed Cell Spray Foam Insulation Made of
The insulation comprises ISO and Resin. These two liquid components are delivered at the installation site in two different containers.
One container comprises methylene diphenyl diisocyanate and polymeric methylene diphenyl diisocyanate. The other container is typically a mix of catalysts, polyols, blowing agents, flame retardants, and surfactants.
The components in the two containers are then carefully combined to create the closed-cell spray insulation. The reaction usually takes seconds, and the spray application begins.
Benefits of Spray Foam Insulation
First, spray foam insulation provides a tighter seal. Therefore, air and moisture penetration are almost impossible, which helps your building and surfaces maintain their integrity.
Closed spray foam insulation is also energy efficient. With closed-cell insulation, you may not need the aid of non-eco-friendly sources of energy like coal to either keep your surroundings warm. This helps reduce your carbon footprint and maintain the ozone layer. Minimal electricity is also needed to keep your indoors cool.
The thick insulation barrier ensures high thermal value, thus providing superior temperature regulation. During summers, the flow of heat into your building remains low; during the winter, your indoor temperature remains optimal as cold air does not flow from the outside.
Cost of Spray Foam Insulation
The cost of spray foam varies depending on the area of maintenance. The installation price per board ranges from $0.44 to $1.50, but regardless of cost, you should consider insulating your home as it helps you save on energy costs over time.
