Blown wool
for attic floors, ground floors, walls, usable and non-usable attics, for frame buildings, and for supplementing thermal insulation
Ekovilla is a carbon neutral blown wool. It is Finland’s favourite insulation for single family dwellings, but is also widely used in professional construction. Our blown wool is mainly made from plain newspaper and it has been used for insulating the homes of our customers for over forty years.
The properties of blown wool
Blown wool has the good properties of an eco-efficient insulation: it is made mainly of recycled wood fiber, it is a carbon neutral product and as an insulation saves energy.
Blown wool from renewable resources
Carbon neutral
Excellent thermal insulation capacity
Good structural fire resistance
Breathable and safe
Suitable for both new buildings and renovation
The suitability of blown wool
The Ekovilla blown wool suits well for wood construction and it is ideal for use in the same projects as the Ekovilla slab. Ekovilla insulation is manufactured from selected recycled newspaper, to which we add flame retardants. Our insulation products can be used in new buildings, renovations and for additional insulation. Main applications: attic floors, ground floors and walls. Thanks to its good moisture transfer capacity this insulation, produced in Finland since 1979, also works well in passive houses.
With blown wool, the thermal insulation of attic floors and ground floors goes quickly. An authorized Ekovilla installation contractor brings the insulation materials and equipment and takes professional care to complete your insulation. Blown wool fills even the smallest cavities and creates a uniform and effective insulation layer.
Utility of blown wool
Ekovilla blown wool is well-suited for wooden constructions and is ideal for use in the same projects as Ekovilla boards. Ekovilla insulation is produced from selected newspapers recycled, to which we add flame-retardant agents. Our insulation products can be used in both new buildings and during renovations as additional insulation. Main applications: for attic floors, ground floors, and walls. Thanks to its good moisture transfer ability, this insulation, produced in Finland since 1979, also performs well in passive houses.
With blown wool, the insulation of attic floors and ground floors proceeds quickly. An authorized Ekovilla installation contractor will bring insulation materials and equipment and professionally handle the insulation process. Blown wool fills even the smallest voids, creating a uniform and effective insulation layer.
Ekovilla's installation service has been dealing with insulation throughout Finland for almost four decades. You can order Ekovilla blown wool as a "turnkey" service at a building supply store, from a prefabricated house seller, or from an Ekovilla installation contractor.
From them, you will receive guidance on properly preparing the object for thermal insulation. Ekovilla uses blown wool in new buildings as additional insulation and as part of renovation work. You can also turn to your Ekovilla insulation installer for professional advice on challenging insulation-related questions.
