Flat roof insulation
The water and heat insulation of the flat roof of the building can be solved in one step with the sprayed foam. Equally unbeatable for saving old roofs, or for economical and quick insulation of newly built roofs.
Closed-cell foam + UV protection (Polyurea)
With one team 350m2/day
Min 3 cm, max 20 cm
Closed cell foam: 55kg/m3
The modernization of flat roofs is one of the main uses of closed-cell polyurethane foam. We not only offer the most effective thermal insulation available today, but we also promise waterproofing! All this in one step, without complicated layers, economically.
The big advantage of the technology is that we don't have to break down old layers and transport the old insulation to garbage dump. This would in some cases more expensive than the new insulation itself.
More and more architects are designing new family and apartment buildings and office buildings with SPF technology. The insulation is free of gaps, there are no soakings or thermal bridges. The closed-cell foam follows the movements of the roof, does not crack, so there is no need tu build in dilatation strips. If you would like to read more about closed-cell foam, click here!
SPF adheres to most building industry materials with the power of instant adhesive, it can be used on bitumen, concrete or wooden closing slabs.
If the foam will be covered (concrete, pavement, gravel bed, green roof, paving slabs), the insulation does not need to be protected. If the outer foam layer is exposed to the sun, it must be UV protected. In such cases, we protect the insulation against the harmful effects of the sun with a two-component Polyurea layer.

Problems with traditional insulation materials
Poor thermal insulation means high cooling and heating costs.
Aged, outdated roofs often get wet.
Condensation appears on the ceiling of the upper level.
Most traditional materials do not follow the movement of the building, even small unevenness can cause cracks.
Complicated layering: traditional thermal insulation materials do not provide waterproofing, and waterproofing does not provide thermal insulation. A more complicated layering system brings with it more errors. In the event of a breakdown, the dismantling and removal of the layers means a lot of costs.
Rodents move into old insulation materials.
The solution: closed-cell foam
SPF provides thermal insulation that is twice as effective as traditional insulating materials (closed-cell polyurethane foam has 0.023 λ [W/mK]).
We promise 100% waterproofing even with the minimum thickness of 3 cm. No more condensation problems. The material lets the vapor through to a certain extent, this way your house remains breathable.
A continuous, gap- and thermal-bridge free surface. Light, yet rigid, walkable surface. The foam and the protective UV layer follows the movement of the building, there are no expansion problems.
Simple layering - no chance of failure. You do not need to dismantle or transport the old insulation before making the scattered insulation.
Rodents do not like foam, or they don't find gaps where they get into the old insulation materials.
How thick should it be?
In today's world, insulation is a prominent topic. Since more than half of a building's heat loss escapes through the roof, the insulation of roofs is one of the most important issues of the topic. In many cases, we are only called to solve soaking problems, in which case we apply the foam to the surface at a minimum thickness of 3 cm. Although this thinnest layer provides a rather poor thermal insulation, it already protects your building 100% against water. If thermal insulation is also a important, we recommend a thicker layer. The closed-cell foam can be blown to a maximum thickness of 20 cm. This corresponds to 40 cm traditional thermal insulation (wool, eps).
SPF has been used in Europe for 60 years, experts predict an 80-year lifespan for the material - with a little exaggeration, we can say that it has an eternal life. The Polyurea UV protective layer that protects the foam is also strong and, if used competently, protects the insulation from environmental influences for decades. It is important to know that the protective coating is not recommended for long-term physical stress. If you use the flat roof as a terrace, Poliurea can wear off. In such a case, it is better to protect the foam with flagstones, tiles or a gravel bed.
