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.

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).

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.

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.

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.

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. 

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.

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.

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.

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.

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.
