Our reference projects are above all one thing:

Well insulated.

Sheep's wool is a versatile insulating material that shows its strengths in the thermal and acoustic insulation of a wide variety of projects. As we like to say: sheep's wool insulation can be found in the best houses - from apartment blocks and company buildings to yurts and tiny houses, this healthy natural insulating material provides the best service.

The Taborama residential building has it all in the truest sense of the word: it's the first high-rise building in Austria to use natural sheep's wool as ecological interior insulation. 29,000 m² of ISOLENA insulation provides insulation, good air quality and a favourable CO2 balance.

House Kittenberger, AT

A green roof, trees for natural cooling and a garden that is a real gem: when building his timber house, Lower Austrian gardening professional Reinhard Kittenberger placed great value on nature. For the window connections, the Dorn company therefore consistently used chemical-free ISOLENA window filler.
