What is closed cell foam Insulation?
Closed-cell insulation, also known as closed-cell spray foam insulation, is a type of insulation material used to create a thermal and moisture barrier in buildings. It is called “closed-cell” because the tiny foam cells within the material are sealed off from one another, giving it a rigid and compact structure.
Closed cell spray foam:
Adds wall racking strength and impact resistance.
Is ideal for continuous insulation.
Can be applied at very low temperatures.
Has lower vapour permeance.
Rejects bulk water (making it ideal for use in flood zones).
Higher tensile and bond strength.
Higher Thermal Value per cm (making it convenient to apply in narrow spaces).
Key aspects and applications of closed-cell insulation:
Strength and Durability: Due to its rigid structure, closed-cell foam adds strength and stability to the structures it insulates. It can also help reinforce walls and roofs.
Spray Application: Like open-cell foam insulation, closed-cell foam is typically applied using a spray gun. During application, it expands to fill voids and adheres to the surfaces, creating a seamless barrier.
Applications: Closed-cell insulation is used in various applications, including insulating walls, roofs, crawl spaces, basements, and foundation walls. It is also used in commercial buildings.
Fire Resistance: Closed-cell foam insulation is generally more fire-resistant compared to open-cell foam, adding an extra layer of safety in case of a fire.
Higher Cost: Closed-cell insulation is often more expensive than open-cell insulation, mainly due to the materials and installation process.

Soundproofing
Green Tech Solutions Open-cell foam offers exceptional soundproofing qualities, effectively mitigating noise pollution.
Expansive
It expands nearly 100 times its initial spray application, effectively insulating every nook and cranny of your property.
Closed cell foam areas of application
Closed-cell spray foam insulation is indeed a versatile and durable insulation option, making it suitable for various applications in both commercial and residential settings.
Metal Buildings: Closed-cell spray foam is often used to insulate metal-framed structures like warehouses, industrial facilities, and agricultural buildings. Its ability to provide both thermal insulation and moisture control is valuable in these environments.
Commercial Areas such as Offices: Closed-cell insulation is an excellent choice for insulating commercial office spaces. It helps create a comfortable and energy-efficient indoor environment while also providing structural support.
Basements and Crawl Spaces: Closed-cell foam is particularly well-suited for insulating below-grade spaces like basements and crawl spaces. Its moisture resistance helps prevent water intrusion and mold growth, making it a reliable choice in damp environments.
Application in Exterior Areas: Closed-cell insulation can be applied to the exterior of a building, such as on exterior walls or roofs.
