There’s been a lot of chatter in the construction industry about creating more efficient buildings. From commercial properties to residential enterprises, the need to increase the energy performance of individual buildings is on the rise. Consumers are more budget-conscious than ever and green buildings make sense in an era where oil and electricity prices have climbed higher than ever before.
Fortunately, there’s an affordable and easy to install option called closed-cell spray foam insulation that has quickly gained notoriety because of its energy efficiency. The building material creates an air-proof envelope around the building, making it more efficient in any temperature.
What is Closed-Cell Spray Foam Insulation?
Closed-cell spray foam insulation is a type of expandable polyurethane that has a medium-density and can be used in virtually any space. It is ideal for commercial or residential buildings and is typically used in exterior walls, attics or floors. The average R value is somewhere between 6 and 7 per inch. A single cubic foot weighs roughly 2 pounds when fully cured. Once sprayed, the foam expands up to 50 times its original volume, then hardens to form a rigid structure.
Closed cell insulation consists of a matrix of densely packed cells that have a special gas locked inside. The foam is moisture-resistant, making it ideal for damp environments. Most closed-cell spray foam insulations use HCFCs or HFCs as the blowing agent.
Like with any insulation, proper installation is the key to maximizing the benefits. The foam should be installed in such a way that the building becomes completely encased, as if in an envelope. When installed using the correct product formulation and manufacturer-suggested application, closed-cell insulation can be expected to last the lifetime of the structure without condensing or losing insulating capabilities.
When applying the insulation, the 2 components are stored separately in a special canister with a long hose and special nozzle attached. The nozzle allows the chemicals to mix just before being sprayed. Once mixed, the chemicals create a foam that expends to fill all types of cracks and crevices, holes or voids. It is usually applied less than an inch thick and allowed to expand to fill the space. Once hardened, the excess foam can be trimmed away if needed.
Benefits of Spray Foam Insulation
Closed-cell spray foam insulation offers excellent heat retention as well as moisture control. It is extremely rigid and durable when cured, which means it can be used to add structural integrity. Spray foam insulation doesn’t shrink or settle, so you will never have gaps that require re-insulating. The foam spray is even approved by FEMA as being flood resistant.
