Advantages of sheep's wool insulation in log cabins:

100 % Natural, moisture-regulating with excellent insulation value

Sheep's wool and wood are two natural materials in perfect harmony: They breathe and adapt, providing effective insulation and a healthy indoor climate – completely free of chemicals.

More than just insulation

Advantages for log house builders

ISOLENA sheep's wool is the perfect complement to wood - natural, durable and technically convincing.
  • Moisture regulation: Sheep's wool is water-repellent and absorbs excessive moisture from the surrounding air without losing its insulating effect.
  • Outstanding insulation performance: Provides the best insulation values of 0.033 - 0.038 W/mK in a natural way.
  • Ecology: ISOLENA means 100% pure new sheep's wool. Renewable, free from chemicals and supporting fibres with a positive CO₂ balance.

Thinking economically means considering the total costs

"We didn't believe it ourselves before ... "

An Austrian log house manufacturer has switched its insulation to sheep's wool - with clear results. Everything meticulously documented with a stopwatch and sharpened pencil.

It is not only the price of the material that matters – but also what ultimately happens on the construction site. A fair price comparison shows that ISOLENA sheep's wool significantly reduces overall costs. And that's not even mentioning the ease of processing and healthy living.

The facts from practice:

  1. Offcuts„Experience has shown that wood fibre insulation requires around 15 % more material. With sheep's wool, on the other hand, we subtract the area of the wooden studs, which means 7 % less material is required in the measured structure.“ (see graph below).
  2. Waste disposal: Timed: 2 skilled workers collect rubbish and then dispose of it, time required: 2 hours. Calculated at 4 hours at 70 € per hour.
  3. Working hours: By eliminating cutting to size, cutting out for installations, uncomfortable working conditions due to protective clothing and dust exposure, practice shows: "Installation is at least half as fast!"

The result: Less material, less effort, lower costs - with better processing quality and more satisfied skilled workers.
