PUR foam wall insulation

Insulation of walls with PUR foam

Spray insulation on walls is a solution that brings real benefits – not only thermal, but also economic and health benefits. In many cases, it is the only effective method to eliminate problems with cold and moisture inside the building. Thanks to the unique properties of PUR foam, it is possible to make durable and safe insulation even in places where traditional solutions fail.

What is polyurethane foam wall insulation?

PUR foam wall insulation involves spraying two components directly onto the wall surface. The process occurs quickly – the material foams, increasing in volume more than thirty times and tightly filling every space. The result is a seamless, thoroughly adherent layer of insulation that effectively protects against heat loss and moisture penetration.

Why does spray insulation of walls work?

The unique structure of PUR foam makes it possible to seal even hard-to-reach places. The use of this technology eliminates thermal bridges – the places through which heat most often escapes. As a result, spray thermal insulation of walls provides an even temperature and noticeably increases thermal comfort in rooms.

PUR foam insulation of walls – the most important advantages

The best thermal conductivity coefficient, which translates into lower heating bills.
No interference with the structure of the wall – the foam does not require the installation of frames or attaching the material.
Lightness of open-cell foam – does not weigh down partitions, ideal for interiors and partitions.
Closed-cell foam – reinforces the wall structure, insulates and stiffens.
Neutrality for health – PZH approvals confirm safety in residential buildings.
Durability of up to 25 years – insulation parameters remain constant for decades.
Fast application – up to 200 m² in one working day.

Why choose PUR foam for wall insulation?

Thermal comfort in every room

Insulating walls with polyurethane foam is a way to improve thermal conditions in selected parts of the house. You decide which interiors are to be insulated – without the need to interfere with the entire body of the building. This approach is ideal, for example, in the case of attic adaptations or thermal upgrading of corridors.

Structure protection

Spray insulation for walls protects not only from heat loss, but also from moisture and mold. Importantly, it does not damage the wall – if necessary, it can be removed by hand without damaging the substrate. That’s why it is often chosen when renovating historic buildings or delicate structures.

Longevity and stability

PUR foams are designed to last – both physically and technically. Foam does not settle, change volume or crumble. It retains its thermal insulation, fireproofing and compression resistance properties for up to 25 years.

Customizable solution

PUR foam wall insulation uses both open-cell and closed-cell foam – depending on the construction of the building and the desired effect. This allows each investment to be precisely tailored to individual needs, without compromise.

FAQ – PUR foam spray insulation for walls

Is PUR foam safe for humans?

Yes, PUR foam wall insulation is completely safe for residents. Each product undergoes regular quality tests – both internally and externally – that confirm its neutrality to humans and animals. What’s more, the foam has a high class of reaction to fire and does not produce burning particles, further increasing safety in the event of a fire.

Does PUR foam stay in place for many years?

Yes, spray thermal insulation of walls made of PUR foam maintains its form, density and effectiveness for a very long time. Thanks to its dimensional stability, the foam does not settle, deform or lose its properties even under the influence of moisture or temperature fluctuations. It is much more durable than traditional insulation materials.

Which foam will be best for insulating walls?

The choice of a particular type of foam depends on the type of wall. For hard partitions, such as reinforced concrete or brick, closed-cell foam is recommended, which further strengthens the structure. For lighter walls, such as wood, open-cell spray insulation for walls will work better, as it is more flexible and does not weigh down the structure.

Can I insulate the walls myself with PUR foam?

Effective insulation of walls with PUR foam requires specialized knowledge, experience and appropriate high-pressure equipment. Therefore, the best results are provided by the application performed by certified specialists from our company. Only then can you be sure that the foam has been properly applied and will perform its insulating function for many years.

How much does it cost to insulate walls with PUR foam?

The cost of insulating walls with polyurethane foam depends on several factors:

wall surfaces to be sprayed,
The type of PUR foam used,
The availability and complexity of the work.
