What Is Polyurethane Foam?

Polyurethane foam is a high-performance thermal insulation material formed by the controlled chemical reaction of two main components. During application, it expands, strongly adheres to surfaces, fills gaps, and creates a seamless insulation layer without joints.

Thanks to this property, polyurethane foam is widely used in roofs, terraces, facades, floors, and industrial applications.

In modern energy-efficient buildings, polyurethane foam helps reduce heat loss and improves the overall durability and performance of structures.


Where Is Polyurethane Foam Used?

Polyurethane foam has a very wide range of applications in both construction and industrial sectors:

  • Roof insulation
  • Terrace insulation
  • Exterior wall insulation
  • Floor insulation
  • Cold storage facilities
  • Tank and pipe insulation
  • Warehouses and factories
  • Prefabricated structures
  • Industrial buildings

It is suitable for both new construction and renovation projects.


How Is Polyurethane Foam Applied?

Polyurethane foam is typically applied using spray equipment. Before application, the surface is cleaned and prepared. Then the material is sprayed onto the surface, where it expands rapidly and hardens.

Key advantages of the application method:

  • Full adhesion to the surface
  • No gaps or voids
  • Seamless insulation layer
  • Reduction of thermal bridges
  • Fast application process

Correct thickness and density selection are critical for performance.


Types of Polyurethane Foam

Open-Cell Polyurethane Foam

Lightweight structure with good sound insulation performance. However, it has lower water resistance compared to closed-cell systems.

Closed-Cell Polyurethane Foam

Higher density material with excellent thermal insulation performance. It has low water absorption and high resistance to external conditions.

In construction, closed-cell foam is commonly preferred for roofs and exterior applications.


Advantages of Polyurethane Foam

Polyurethane foam offers several advantages compared to traditional insulation materials:

  • High thermal insulation performance
  • Seamless application (no joints)
  • Fast installation
  • Lightweight structure
  • Easy adaptation to complex surfaces
  • Long service life
  • Water resistance (depending on type)
  • Reduced energy costs

For this reason, it is widely used in both residential and large-scale industrial projects.


Flokser Polyurethane Solutions

One of the leading brands in the polyurethane sector is Flokser Kimya.

Flokser develops polyurethane systems used in construction, automotive, and industrial insulation applications. The company offers spray foam systems and customized solutions with different density options for various project needs.

In polyurethane applications, not only product quality but also correct equipment, density selection, and application technique are critical. Therefore, choosing a reliable brand is an important decision factor.


Polyurethane Foam Prices

Polyurethane foam pricing depends on several factors, including project size, application thickness, material density, and application complexity.

Main pricing factors:

  • Total surface area
  • Required thickness
  • Foam type (open-cell or closed-cell)
  • Surface condition
  • Labor and equipment requirements
  • Project location

For accurate pricing, a project-based technical assessment is required.


How to Choose Polyurethane Foam?

Choosing polyurethane foam requires more than just selecting a product. Key factors include:

  • Technical specifications
  • Density value
  • Thermal conductivity coefficient
  • Fire performance
  • Water absorption rate
  • Surface compatibility
  • Application expertise

Incorrect product selection or poor application can significantly reduce performance.


Frequently Asked Questions
