Attic insulation with Jutedämmstoff


Insulate the roof sustainably

Ecological insulation materials play an increasingly important role. They not only allow a pollution-free living, but also contribute to environmental Protection. For organic insulating materials, renewable raw materials are used which can be processed without large energy consumption into insulating materials.

As the eco-insulation materials recycled or composted, they do not cause expensive and polluting waste. Meanwhile, there are a number of ecological insulation materials, these include insulation materials made of hemp, seagrass, cellulose (paper), wood fiber and more recently, jute.

Due to the good properties, this substance is therefore suitable for the insulation of roof trusses.

What is Jute?

Falsely Jute is often mistaken for a plant. Strictly speaking, these are but a vegetable fiber the Corchorus plants. The natural fiber is located between the bark and the stems of the plant: the so-called Bast. Through a special process, the roasting, the natural fiber can detach. is usual, the water retting, in which the plants are placed for several days in water. Through subsequent breaking and swinging the individual components of the tropical plant are separated. The main growing area of ​​Corchorus plants located in Bangladesh and India.

From used jute bag for high-performance insulation

Jute bags are recycled in the ReißereiJute bags are recycled in the Reißerei

The Jutedämmstoff not based on newly won jute, but on used jute bags for food. These jute bags transported coffee and cocoa beans from around the world to the German coffee roasters and chocolate manufacturers. Instead of ending in the waste incineration, the jute bags are recycled. To this end, the bags in a Reißerei are torn apart by machine, so that at the end again quality jute arise. The fibers are mixed with the mineral Soda as fire protection and with a textile support fiber as a kind of binder. a non-woven is then placed in the carding plant in a mechanical process produced, which is heated to the circuit in the thermobonding process at 170 degrees Celsius. In this way, the substance solidified. If higher value products produced from waste, it is called Upcycling.

Versatile roof insulation

The ecological insulation jute finds its use as insulation between rafters, below the rafters or rafter between the support rafter. Furthermore, the Jutedämmstoff can also be used for the insulation of metal stud walls, wooden beams, as well as linings of exterior and interior walls in wood frame and wood frame construction.

Professionally insulate with jute

Insulation of jute bagsInsulation of jute bags

The Jutedämmstoff is available in rolls and therefore very flexible in its handling. Thanks to its easy fitting it is also suitable for home improvement. The 1200 mm wide rolls can be worked easily with a standard electric cutting tool or a serrated knife. The insulation material is very during installation kind to the skin, it triggers neither troublesome itching are other skin irritations.

When handling it differs little from other insulation materials: So should the first be tailored accordingly. Using the insulation between rafters, it is recommended that the roles one to two centimeters to cut wider than the actual rafter spacing.

Next, it clamps the insulation elements between the rafters. Subsequently, a sealing tape is attached to the rafter and a Vapor barrier stapled to the rafters. The individual foil webs should overlap approximately 10 cm. After that, the seams of the film webs are sealed with tape.

At the end is a Transverse lathing as a substructure appropriate. The resulting space can accommodate an additional under-rafter insulation.

Best thermal insulation through low thermal conductivity

Jute has an above-average level of insulation and, like most ecological insulation materials, higher thermal conductivity than conventional insulation. The greater the thermal conductivity, the worse insulates a building material. While glass wool very good values ​​between 0.032 to 0.035 W / mK (watts per meter Kelvin times) is reached, are the higher of hemp and wood fiber, each with 0.040 W / mK and therefore worse. Jute having a value of 0.038 W / mK an insulation material which sometimes best contained under the Eco-insulating materials.

Summer heat protection

Apart from thermal protection, the Jutedämmstoff before an effective summer heat protection. The ecological insulation sells from morning to night the heat under the roof. This corresponds to approximately nine hours. Glass wool, however, can, under the same conditions, only until noon, so about four hours, make an effective heat protection.

Sustainable insulation with high availability

The Jutedämmstoff is by no means a material with limited availability of raw materials. In the future there will be the raw jute enough. World production of jute per annum between two and three million tonnes. more than 100,000 cubic meters of the insulating material can be produced per year.

BENZ24 | The online store for building materials

This provider sold as the first and only store a Jutedämmstoff which to at least 85 percent of jute consists. The BENZ24 THERMO JUTE FLEX runs as a private brand of the shop. All other insulation materials available with Jute share still contain a certain proportion hemp. The eco-insulation material is compared to many other natural insulation available at a reasonable price. In an insulation thickness of 180 millimeters, the insulation will cost 14.99 euros per square meter.
