About Spray Foam Insulation

Polyurethane Spray Foam Insulation (Also called “steel resin”) is a highly efficient and durable thermal insulation material, commonly used for insulation and sealing of walls, roofs, floors and other parts of buildings, industries and commercial places. Polyurethane foam is a material that is mixed with two components (component A and component B) and sprayed through a spraying device. It has excellent thermal insulation and sealing effects.

Features of Spray Foam Insulation

1，Heat insulation and noise reduction

Spray Foam Insulation uses high-density closed-cell foaming technology, and the bubbles are independent of each other. It isolates the transfer of temperature and perfectly solves the problem of too high temperature in summer and too low temperature in winter in steel structure factories. At the same time, Spray Foam Insulation has strong adsorption and obvious noise reduction effect, which effectively reduces the noise problem caused by rain hitting the roof of steel structure buildings in rainy weather.

2，Water Proof

Before waterproofing colored steel tiles, you must first accurately find the leaking points and cover them with waterproof materials to achieve the waterproof effect. However, the actual situation is that there are many hidden leaking points on site that even professional construction workers may not be able to find, which can easily lead to repeated leaks on the roof. Our Spray Foam Insulation has very good waterproof performance, fully covers colored steel tiles, hides leaking points, and eliminates leaks!

3，Enhanced pressure resistance

After years of use, metal roofing panels often lose strength and become fragile, creating a risk of collapse when walked on. However, a roof insulated with Spray Foam Insulation gains enhanced structural strength, filling gaps and stabilizing any loose areas. Once cured, the high-density foam layer evenly distributes pressure across the surface, preventing localized damage from pressure points and making the roof more durable. Additionally, the strong adhesive quality of the spray foam creates a firm bond with the roof, further boosting its load-bearing capacity. This insulation also provides superior thermal and moisture resistance, extending the roof’s lifespan and reducing maintenance costs.

4，Durable

Spray Foam Insulation has high weather resistance. The coating will not powder or fade in the wind and rain. It also has high toughness, strong bending resistance, and is not easy to break.

5，Fireproof

Spray Foam Insulation inherently possesses permanent flame-retardant properties and is further enhanced with inorganic flame retardants, providing double-layered, enduring fire resistance. This dual approach ensures that the foam insulation can effectively withstand exposure to flames without supporting combustion. The inorganic flame retardants embedded in the foam composition create an additional barrier, releasing protective gases when exposed to high temperatures, which slows down the spread of fire. This robust flame-retardant capability not only prevents ignition but also minimizes the risk of fire propagation across insulated surfaces, offering a lasting safety solution for buildings and structures.

Anti-corrosion

6，Anti-corrosion

Spray Foam Insulation is tightly bonded to the color steel tile roof, effectively isolating the color steel tile from further reaction with air, acid, alkali and organic solvents to cause rust.

7，Beautiful

Spray Foam Insulation has a variety of color options and will not fade even when used outdoors, providing a better visual experience.

Photovoltaic Applications

Photovoltaic
Applying Spray Foam Insulation to a tin roof and installing a photovoltaic system on it can not only improve the structural stability and thermal insulation performance of the roof, but also effectively extend the service life of the roof and photovoltaic system with the following characteristics:

1，Overall anti-corrosion and waterproof

After the photovoltaic base is installed, the entire roof is sprayed with Spray Foam Insulation, which is seamlessly connected and fully covered to achieve overall anti-corrosion and waterproof functions.

Physical performance improvement

2，Physical performance improvement

Spray Foam Insulation anti-corrosion paint film has high wear resistance, which can solve the damage to the roof caused by photovoltaic management and maintenance

3，Extend service life

Spray Foam Insulation has excellent weather resistance. In the use environment of wind and rain, the coating remains non-powdering and non-shrinking. At the same time, it has high toughness, strong bending resistance, and is not easy to break. The roof can be used for 20 years after spraying.

Spray Foam Insulation Construction Steps

1，Cleaning the surface

Treat the surface of the color steel tiles according to the construction instructions, clean the rust on the surface, and meet the construction requirements.

2，Roller anti-rust primer

Apply the special anti-rust primer in one or two coats by rolling or scraping on the base surface.

3，Spray Foam Insulation Construction

Debug the sprayer and spray the Spray Foam Insulation paint evenly on the anti-rust primer layer to maintain the uniformity of the Spray Foam Insulation.

4，Polyurea Topcoat Construction

Use a spatula or a brush roller to evenly apply the polyurea topcoat (floor waterproof finish three-in-one) on the Spray Foam Insulation.
