How much does foam insulation cost?

The price of our foam insulation depends on several factors. Below we describe the variables that affect the unit cost of work.

Scattered purhab price

Closed-cell foam

35-55 kg/m3

Open cell foam

15 kg/m3

UV protection

Polyurea/synthetic resin

Purfoam insulation price, dispersed purfoam price - what does it depend on?

The expanded foam price is usually calculated on a per square meter basis, reflecting the thickness. The price of foam insulation therefore depends on the building or from the size of the surface to be insulated. Secondly, it is important to choose the thermal insulation value to be achieved and to determine the thickness of the insulation. Of course, the chosen polyurethane foam also affects the price.


Defining the surface is the simplest task. It is important to remember that for a non-flat surface, the material requirement for insulation must always be calculated using the spread size. This multiplier, called spread, is usually +15% in the case of a flat trapezoidal plate or corrugated sheet. It is clear to everyone that in connection with a small order, we cannot calculate specific costs as favorably as in the case of a huge surface. From the point of view of the price of foam insulation, it does not matter whether our insulators travel for several hours and prepare for a 10 m2 surface or work continuously for days on a large flat roof. Due to the costs of disembarkation, preparation for work, equipment and heating of the material, insulation is not cost-effective for a small task. Generally, a surface of at least 100-200 m2 is where we can give our customers a favorable price. Of course, the minimum order is not only a function of the square meter, it can also be greatly influenced by the ordered thickness or the location of the object.


In most cases, our customers have a specific idea about the thickness of the insulation. Compared to traditional materials, closed-cell polyurethane gives the building the same effective thermal insulation at half the thickness. Where the task is only waterproofing, or where condensation problems need to be solved, it is sufficient to apply a thin, 3-4 cm thick insulation. For those who specifically order polyurethane for thermal insulation, we will recommend a minimum of 6-8 cm of closed-cell foam to achieve medium thermal insulation - on a surface that is not yet insulated. For a strong, 30-cm-thick traditional thermal insulation, it is necessary to calculate with 15 cm of spread foam. With closed-cell foam, we can make thicknesses between 3-20 cm. There are projects where an accurate assessment of the surface to be insulated is impossible. In such cases, we settle with the customers at the prices set in the contract, based on the weight loss, calculated in liters.

External or internal work

THE The price of purfoam insulation may vary depending on the type of material used and the nature of the surface to be insulated. It is sufficient to cover an internal wall or ceiling with polyurethane only, while the insulation being prepared for an external surface must also be provided with sun protection. The prices without a UV protective layer are significantly lower than in the case of an external wall or roof insulation, where we have to protect the foam with polyurea.


The price of foam insulation also depends on whether preparatory work is required. Although the great advantage of the technology is that the old insulation and its layers do not have to be dismantled, there are cases where this is unavoidable. if, for example, the outer boundary layer of the surface is loose, it must be fixed so that the foam does not pull it away from the surface to be insulated during swelling. During the insulation, small polyurethane particles fly in the air, which is why there are jobs where it may be necessary to cover nearby windows and landmarks. Such and similar works may affect the price as they require time and resources.

Building, accessibility

The price of loose foam naturally depends on factors such as the geographical location, the condition of the building, and the difficulties of accessibility. We can insulate from our own scaffolding up to a height of 7 m, to insulate higher surfaces, the cost of a personal lift must also be calculated. 


In order to give you at least some entry-level reference at the end of the article, below you can see what price you can calculate for a small job:

  • closed cell made of foam, for example on an attic floor with a bulk density of 35-40 kg/m3: net HUF 1750/cm/m2
  • open cell made of foam, for example on an attic floor with a bulk density of 15-20 kg/m3: net HUF 780/cm/m2
  • UV protection, for example on a flat roof with a thickness of 2 mm: net 5800 FT/m2
