Spray Applied Polyurethane Foam Insulation
Spray Applied Polyurethane Foam Insulation is an advanced insulation material that consists of two components and is applied using a spray application method. It is a closed-cell rigid polyurethane foam that offers excellent insulation properties and finds wide usage in various industries and applications.

Polyurethane foam insulation provides a high level of insulation due to its low thermal conductivity, which effectively minimises heat transfer between the interior and exterior of a building. This characteristic helps maintain a comfortable indoor environment and significantly reduces the energy consumption required to heat or cool a space.

Additionally, Polyurethane Foam Insulation offers several other benefits. Its excellent adhesion properties allow it to conform to various surfaces, including walls, roofs, and irregular shapes. This seamless coverage eliminates air leakage and minimises the infiltration of moisture, which can lead to mould growth and structural damage. Spray Applied PU Foam Insulation also acts as an effective sound barrier, reducing noise transmission and improving acoustic comfort within a building.

The application process is relatively fast and efficient, as the foam can be sprayed onto the desired surface, expanding and solidifying within seconds. This quick installation minimises project timelines and reduces labour costs.

  • Residential, commercial, industrial, and institutional buildings, etc
  • Roofing & wall systems, between steel or wood framing, over RCC slabs
  • Tank insulation
  • Cold storage solutions
  • Air barrier system
  • Superior Thermal Insulation
  • Quick and Efficient Installation
  • Improved Indoor Air Quality 
  • Versatility and Flexibility
  • Seamless Coverage
  • Moulds to any surface, even uneven ones, create a smooth and tight seal. This prevents air leaks and lowers energy consumption.
  • Blocks moisture, prevents water infiltration and reduces the chances of mould growth and structural harm.
  • Reduces noise transmission, enhancing acoustic comfort in the building.
  • Versatility and Flexibility can be used for both new constructions and existing structures.
  • High adhesion to diverse surfaces like wood, metal, concrete, and masonry.
  • Moisture barrier properties prevent water infiltration, safeguarding buildings against mould, rot, and corrosion.
  • It supports sustainable construction through energy savings, reduced emissions, and enhanced energy efficiency.
  • The plural component proportioner must supply each component within ± 2% of the desired 1:1 mixing ratio by volume.
  • Hose heaters should be set at 50°C to 55°C to ensure proper delivery of materials to the spray gun.
  • These settings facilitate thorough mixing in the spray gun mix chamber during typical applications.
  • It is sprayed onto the prepared roof surface using two components that expand when mixed.
  • The foam forms a seamless layer of rigid foam that can be walked on within minutes.
  • The foam cures to 90 percent of its full strength in approximately four hours.
  • Polyurethane spray foam insulation adheres to most surfaces, both horizontal and vertical.
  • It creates a fully adhered, self-flashing, monolithic roof surface.
  • Unlike other roof systems, it eliminates critical failure points such as seams and penetrating fasteners.
What is spray polyurethane foam used for?
Is polyurethane spray foam insulation safe?

Polyurethane spray foam insulation is generally safe once fully cured and hardened. However, during application and curing, it can release volatile organic compounds (VOCs) and isocyanates, which may cause health issues if inhaled. Proper ventilation, protective gear, and adherence to safety guidelines are essential during installation to ensure safety.

Can polyurethane foam be used as insulation?

Polyurethane foam excels as a versatile insulation material. Its ability to expand and fill uneven spaces creates a seamless barrier, effectively trapping heat within or minimizing its entry. This translates to improved energy efficiency in buildings, leading to reduced heating and cooling costs.

What is spray foam insulation used for?
Is 100% polyurethane foam safe?
Yes, 100% polyurethane foam is generally considered safe for use in various applications, including furniture, bedding, and insulation, once it is fully cured. However, during manufacturing and installation, exposure to its raw chemicals should be minimized. Proper ventilation and safety precautions are essential to prevent inhalation of fumes or contact with skin.
