Insulation methods for when renovating a house

Construction is one of the resource-intensive sectors of the economy in general. 85 percent of all employed in Germany mineral resources – i.e. 551 million tons – each year used for the production of building materials and products.

These products – sand, stones, earth or metal – come from nature. The concept of natural building materials is therefore problematic; I would rather speak of sustainably produced building materials. To make the construction industry long term, we need to focus more on renewable raw materials, pay more attention to energy efficiency in the production and processing and developing new e

If the tested and approved wall construction is used, straw bale houses like any other house can be built.

However, it is still hard to find craft shops that offer this type of construction. House refurbishment – benefit!

In Germany, the building experienced with renewable raw materials for some time a renaissance – not a revolution, but a slow, steady change in thinking.

Especially in the focus is on wood and clay as the oldest building materials of mankind. Are especially popular floor coverings made of wood, but also all the wooden houses – especially in the area of ​​prefabricated. Also linoleum is now backing on the rise.

Also playing a role insulating materials made of flax, hemp, cellulose or wood fibres and wall plasters made from cotton, cellulose, flax, hemp or jute are available.

But these are now just a few examples, the market is very diverse.

People are so inventive: seaweed, for example, only for a few years as an insulation material on the market.

And there are many ideas for recycling of building materials – such as insulation materials are made from recycled paper and old clothes manufactured today.

Incidentally, Rete a good example that the use of renewable raw materials also depends on the availability of arable land.

That he is now only rarely used as a building material, is due to the fact that the roofs of our homes are becoming flatter and could no longer run properly on the water reed.

On the other hand too little acreage would be present, since the cultivation of reeds competes with agriculture.

Cellulose flakes have the largest market share among the renewable insulation materials. As here they are often blown as roof insulation.

Cattail is well suited for insulation as well as other conventional materials.

They are characterized by a high natural resistance to mould from, are light and meet the specific criteria that apply to the renovation of a historic half-timbered house.

The structural panels made from plant fibres and clay, whose development we have supported are not intended for insulation, since they only consist of Construction clay or clay, reeds and jute as well as vegetable and mineral additives.

Clay itself is not the insulation. The plates are therefore used as wall material for interior design. Clay has the advantage that it is produced with low energy consumption, easy to block and requires no chemical conversion processes.

These were tested on a listed building and are ideal for use in similar cases to.

However, a large-scale use always depends on the availability of raw materials and as lacking in cattail simply the area under cultivation, the plant grows so only in bogs and on marshy soils.

When clay it is a little different, this is already often used as a cleaning – often in conjunction with wood fibre insulation boards. Since clay can retain heat well and, moreover, moisture regulating properties, it is ideal for interior walls. But whether his coverage is used in the future, I cannot say. Which also depends on consumer demand?

Sustainably produced building materials cut over conventional building materials from better when it comes to energy efficiency in production and processing. They are also better recyclable usually.

But even if they often have benefits – to ensure that a product is truly environmentally friendly, you have to do life cycle assessment in each individual case. This may occur if renewable resources due to land use lead to similar problems as with bioenergy. We are all familiar with the discussions on the tank and plate.

The one cannot say so flat. Certainly, insulation boards made of natural fibres due to their market position still more expensive than the leader of polystyrene and mineral wool.

But there are very many different ways and insulating materials, so that it always pays to compare prices and to draw insulation with renewable raw materials into consideration.

Roof insulation with cellulose flakes for example does not have to be more expensive than mineral wool. That depends on the size of the roof area and the individual provider.

Finally, also make the cost of the material so only a small part of the total cost of insulation measures. If the material is double the price that does not mean that the insulation is twice as expensive.

Maybe it’s only ten percent more. For a builder in Melbourne that can help you with your project go check out a few.
