When you use spray polyurethane, you don’t have to choose the insulation solution according to the application. Ekospray insulates equally well

One spraying installation performed by the contractor provides a wind baffle, vapour barrier and PU insulation to last from generation to generation for

CE-marked Ekospray is the professional’s simple choice for renovation and facade repairs because the structures do not need straightening or caulking. Spray polyurethane insulation material does not require fasteners, studding or support structures. Neither does it get wet during storage or installation.

Ekospray raises the value of buildings and extends their life.

Apartment houses

Using Ekospray polyurethane, old properties requiring facade renovations are insulated to meet the present-day level of energy efficiency. At the same time as the thermal insulation of structures improves many times over, the insulation layer acts as a wind baffle and vapour barrier. In terms of moisture performance the structure becomes safe and modern.

Spray PU insulation has all the advantages of polyurethane. Compared to more traditional insulating boards, it has many useful additional features. The thickness-scalable insulation layer sits completely firmly and seamlessly on an irregular and multiform wall structure. In this way, facade renovations and other refurbishments can be performed without

In addition to facades, spray polyurethane insulates base floors, roof slabs and wall structures in apartment buildings.

Polyurethane insulation is the professional’s simple and easy choice for the facade renovations of apartment buildings. The so-called sandwich structure of the wall’s external skin as well as old wool insulation are dismantled. There is no need to straighten the inner envelope: Ekospray can be sprayed directly into it. At the same time, the insulation material

With spray PU insulation the thickness of wall structures can be kept unchanged. The present thermal insulation requirement for wall structures of 0.17 W/m2K can be achieved with a 150-mm insulation layer. The desired facade surfacing is added as external cladding.

Base floor construction work in apartment buildings is often left unfinished, and such floors are perfect places for mould and rot. Moisture removal, drainage and ventilation are poorly implemented. Roof slabs for their part are tricky for board insulation because of the roof support structures and ventilation ducts. In addition, the spaces are often very low.

Ekospray offers a safe solution for painless insulation of hard-to-do base floors and roof slabs. It is also possible to insulate roof structures with spray PU insulation from outside.


Spray polyurethane provides insulation according to the varying needs of industries. For particularly hot and particularly cold conditions, special Ekospray insulation materials have been developed which can be cast or sprayed on site.

Examples of the industrial use of spray PU insulation can be found among others

In addition to insulating, Ekospray stiffens and supports the structure that is being insulated. At the same time, it prevents moisture from condensing, e.g. between metal sheet cladding and the insulation.

Ekospray is equally suited to the isolation needs of industrial halls and commercial and public construction. Read more about facade renovation on the Apartment Buildings page.

Private houses

Ekospray is a safe and effective choice for both the refurbishment and additional insulation of old private houses and for the thermal insulation of passive and low-energy houses. In old private houses (such as so-called veteran’s houses and log houses) spray polyurethane sets without trouble to form a compact insulation layer on the surface of old frame structures. At the same time, insulation functions as support for the structures.

The original thickness of the wall structures in wooden houses can be kept unchanged when you use spray PU insulation. Compact and efficient Ekospray boosts living comfort and energy efficiency in the building to the level of present-day requirements. Thanks to its thermal insulation performance, spray PU insulation is also superior when insulating modern passive and zero-energy houses. It is suitable for all building frame materials: concrete, brick, timber and steel frames.

In terms of moisture performance, insulating with Ekospray is safe throughout the year. In addition, the thin insulation layers serve as vapour and air barriers and there is no need to install such barriers separately.
