Insulation of external or internal side walls with closed or open cell foam 

Heat, sound and water insulation in one step, quickly and efficiently. It can be used on all construction materials: noble plaster, brick, plasterboard, ytong, plate, wood, etc. The homogeneous side wall insulation we apply is completely free of gaps and joints, there is no air movement, no heat loss. Particularly effective for wall planes with special shapes, for insulating curved shapes, etc.

Insulation of the inner side walls with purfoam has long been popular, especially for lightweight buildings. Our company also undertakes the insulation of external facade walls. You can read about both topics below.



Due to the spray technology, the foam insulation is not completely flat, the edges are not straight. If you want completely flat walls and do not plan to cover the insulation with a front wall, straightening the edges and smoothing the planes will mean extra material and work for the masons! You can simply cover the insulation of the inner side walls with plasterboard.

Internal side wall insulation

Purfoam is an effective and quick solution for heat and sound insulation of internal side walls/partitions. The excellent properties of gap-free foam make it an unbeatable solution for vertical walls: it doesn't slide down, it's airtight, rodents can't get into the side wall, and the execution is lightning fast.

If a larger hollow space needs to be filled and moisture resistance is not particularly important to you, you can also choose open-cell purfoam. The cheaper open-cell product is lighter and softer than its rigid closed-cell counterpart, and due to its lower price, it is a more economical solution if the goal is to completely fill a relatively deep wall. It is important to know that open-cell foam provides poorer thermal insulation, a thicker layer will be needed to achieve the same thermal insulation.

Facade insulation

Facade insulation effectively! Heat and water insulation in one step, the result is stronger, denser wall surfaces than with usual facade insulation. It can also be used on plastered or unplastered facade walls, it adheres strongly to most construction materials (noble plaster, brick, ytong, plate/panel, steel, wood). As with all exterior work, we must protect the foam from the sun with a UV protective layer. If you cover the wall later, plaster it, or build a front wall, this is of course not necessary. It's more You can read about UV protection here.

The homogeneous side wall insulation we apply is completely free of gaps and joints, there is no air movement, no heat loss. It is particularly effective in the case of specially shaped wall planes, for insulating curved shapes. In all cases, the exterior walls are made with closed-cell foam.

Side wall insulation with foam

  • The same insulation with a thinner layer! Compared to other materials, half the thickness is enough
  • There are no junctions or breaks. The surface is completely homogeneous and continuous
  • Gap-free insulation of specially shaped buildings and curved walls is possible
  • It doesn't rattle like Styrofoam. Solid, strong wall surface 
  • Rodents are the only ones who don't like foam insulation

General benefits of SPF
