For many adventurers and freedom-lovers, the van is more than just a vehicle - it becomes their home and the centre of their lives.
But anyone who travels for long periods of time and drives through different climate zones knows how crucial the right insulation is. Rico and Becca, experienced vanlife professionals, have opted for the sustainable insulation material sheep's wool and share their experience here.
Pure nature is the motto of timber construction. Despite the good insulating properties of the raw material itself, this is often not enough to fulfil energy efficiency, technical suitability and living comfort requirements. It is therefore not a question of whether thermal insulation is necessary in timber construction, but rather which materials best support the fulfilment of these requirements.
Demand in the mail order business is growing from year to year. But so are the requirements for more sustainability. With insulated packaging made from sheep's wool and paper, ecological and high-quality packaging is made easy.

Headaches, burning eyes, irritated airways - all of these can have something to do with indoor air quality.

Many rooms have problems with reverberation: your own words follow you around unpleasantly. Sound absorbers can help. So that your home or office doesn't look like a recording studio, sheep's wool felt is a good idea.
Here we show you how you as a carpenter or interior decorator can create effective and visually appealing acoustic panels with natural wool felt.
On average, we spend around 20 hours a day indoors. The indoor air should be in order. However, pollutants are often hidden in unexpected places. There are many reasons for this: wrong choice of building materials, drying times not adhered to, airtightness, appearance before health ... One of the pollutants that can make you ill if the concentration is too high is formaldehyde.
Ding Dong! The time has come, the haulage company is at the door and your acoustic panels are being delivered. Now it's time to roll up your sleeves and get to work. Here we show you step by step how to install your new absorbers.
Are you planning to build a house, an extension or a renovation? If healthy materials are important to you, you will also be thinking about sheep's wool insulation. We will help you to understand sheep's wool as an insulating material, dispel concerns and prejudices and share with you the experience from our development and numerous construction projects.
The decision in favour of the right insulation depends on many criteria, including the durability of the insulation material. After all, insulation is permanently installed and replacing it is time-consuming, expensive and nerve-wracking. Effective, durable and healthy wool protection that keeps pests away is an important aspect when choosing sheep's wool insulation.
You have the option of customising your ideas for acoustic modules. We have created instructions, including a video, on how to put together acoustic panels using the draw.io tool.
More about us and our sheep's wool
Expertise in wool
All wool is the same? Not quite - we explain the difference between sheep's wool and virgin sheep's wool and much more. We explain what we at Lehner Wolle pay attention to when buying wool and how we process the valuable raw material wool into sustainable products.

Circular economy
Cradle to cradle refers to the idea of an end-to-end circular economy. This conserves resources, avoids waste and increases the service life of products. We take our raw material from nature and process it. In the end, 100 % of the wool is recycled.

Sustainability
We have created an article for our carpet brand FELICE that explains our thoughts and actions on the subject of sustainability. Because there is more to a sustainable product than just a good raw material. The idea of sustainability must be deeply rooted throughout the entire company.
