Scattered purfoam insulation price - what does it depend on?

The price of dispersed foam insulation in 2003 typically ranges from HUF 4,000 to 5,000 net. This price is for the stronger, heavier closed-cell material, including a minimum thickness of 3 cm. It is also true for purhab that you should not decide solely on the basis of price. It does not matter what density and quality of foam we insulate with. There are dozens of brands of closed-cell polyurethane foam on the market, representing different quality categories.

The price is also influenced by whether the work is performed by a supplier with references and decades of experience, or by an entrepreneur just starting out in the industry.  

What material does it stick to?

It can be used on almost any construction material used today: concrete, brick, plastered wall, tar, wood, plasterboard, trapezoidal sheet, flat and corrugated slate. Porous surfaces and insulation of plastics are undertaken after separate consultation.

Is it more expensive than traditional insulation?

It is important to know that the prices we give include not only the cost of materials, but also the execution. An important advantage is that with our technology you don't have to dismantle it in most cases. Overall, it can be said that the price of the foam is competitive if you calculate the costs associated with the installation of other materials (transportation, demolition, removal, fixing, longer construction time, cleaning).

Harmless to health?

Purfoam has been used around the world for 60 years. A misconception about polyurethane is that it can negatively affect air quality or even cause poisoning. There is no scientific basis for this. Closed-cell foam does not emit harmful substances, so it does not affect the health of the people living in the building. Polyurethane is the most effective insulation available today, it is resistant to mold, moisture and other harmful substances.

What thick layer should I order?

Closed-cell foam replaces twice the thickness of cotton or Styrofoam insulation—roughly twice as effective. Closed cell foam: 0.021 W/mK, cotton 0.044 W/mK, EPS 0.048 W/mK. 

With the technology, we can realize a thickness between 3-20 cm. If waterproofing is the goal, the minimum of 3 cm is perfectly sufficient. Where thermal insulation is also important, we recommend a greater thickness. We usually apply a minimum of 8 cm to the attic or side walls of residential buildings.


Does the foam break down over time?

One of the advantages of foam insulation is that it resists structural damage/degradation and also resists settling. Purfoam has been used all over the world for more than 60 years, the experience is that it does not lose its thermal and waterproofing properties even during this time. According to the International Association of Certified Home Inspectors, the lifespan of sprayed foam is more than 80 years.

What if insects attack the foam?

Purfoam helps to prevent attacks by insects and other pests, as it seals the gaps where rodents usually enter. The foam does not attract insects because it is not attractive as a food source. 

Is polyurethane foam a green product?

All insulating materials have one very important property: energy saving. Foam insulation can significantly reduce the energy required to heat or cool buildings. The use of insulation reduces electricity demand, helps conserve valuable fossil fuels, while reducing associated greenhouse gas emissions during power generation.

Some purfoam raw materials are produced from renewable sources, such as natural oil polyols based on soybean or castor oil. These natural polyols are chemicals that are mixed and reacted with other chemicals to create polyurethane foam.

What are the dangers of spray foam insulation?

Gases released during foam insulation and exposure to harmful chemicals can cause lung and eye irritation, shortness of breath, sore throat and fever. However, you can avoid these harmful effects if you use protective equipment during the production of foam insulation. 

We recommend that homeowners stay away from the area while the foam is being sprayed to avoid possible contact with the chemicals. The foam sets immediately and airs out, so you can safely return home after an hour or two.

How to remove closed cell spray foam?

Rub off the foam with a dry cloth, if necessary use acetone on the affected area to remove the particles. On external surfaces, you can use a pressure washer to remove particles.

Many say it is expensive. They do not take into account the fact that we give an executed price when we give a price per square meter. It is important not to compare the price of foam insulation with the raw material price of cotton and EPS, but with the cost of the finished insulation. If you calculate like this, you will see that purhab is more than competitive.


The cells of the closed-cell foam form an AIR-FREE network. Provides excellent thermal insulation. A given thickness replaces twice the traditional insulating materials! The surface is seamless, does not shrink or collapse over time. Even with a minimum thickness of 3 cm, it provides 100% waterproofing. Its huge advantage is that it can be used on any construction material used today, and can be used on almost any wall surface.


Energy consumption can be reduced by up to 60%. During the energy crisis, this is a huge advantage, nowadays only a well-insulated property is marketable. We provide our customers with a performance declaration for the new generation insulation, or 10-year full warranty. With us, the price includes the cost of construction, if you compare our offer with competing products, you will see that purhab is more than competitive.

Homogeneous surface, the foam fills all gaps, airtight. There is no change between the planes, junctions - the possibility of an error is excluded. The completed surface is uniform, without any thermal bridges. Seamless insulation is desirable for all buildings, but it is really attractive on a specially shaped surface. The foam follows all shapes perfectly, which is one of the biggest advantages of insulation.

Condensation in uninsulated buildings is a big problem. When steam constantly drips back from the ceiling onto your neck, just call us! With closed-cell foam, you can eliminate annoying condensation. Condensation occurs where high temperatures meet (for example, on an uninsulated roof): that is, when warm air hits a cold surface. Warm air can hold more humidity than cold air, condensation forms precisely at the point of contact with the cold surface. Even a minimally thick layer of foam is enough to solve this problem. A huge advantage is that the building remains breathable with polyurethane foam: while the foam seals the water, it is vapor diffusive!

Condensation occurs not only on wall or ceiling areas, but also on other metallic surfaces, such as steel beams, storage tanks, windows, concrete surfaces, etc. In animal husbandry, dripping water can cause diseases, and in grain storages and warehouses it causes damage to the crops and products stored there. 

With the spreading technology, progress of up to 1,000 m2 per day can be targeted. Our industrial and agricultural customers really appreciate this, as it is very important for them that the buildings are not exposed for long weeks from production. Even in family houses, the owners are happy that the insulation does not last for weeks. We finish an average-sized attic in 1-2 days. 
Can be used on all construction materials. Without separate fixing, it can be applied directly to roof tiles, corrugated slate, plasterboard, concrete, brick, for wood reed, slag, metal.
The properties of the product do not change over time. It keeps its size and shape for a long time, does not shrink or collapse. They have been working with the material for 60 years in Western Europe, the experience so far has shown that the material does not age even during this time.
With corrugated slate, replacing old, aged, cracked, and broken slates can be a problem, as this is an extremely difficult task and their removal is expensive. For purfoam insulation, it is not necessary to transport the slates. The same applies to bituminous roof insulation: the closed-cell foam can be applied to the tar layer, so it is not necessary to dismantle and transport the hazardous waste.
Self-extinguishing (classified B2), does not feed the fire. It is harmless to health and is not considered hazardous waste.
