Insulation plays a central role in the construction of a house: by focusing on quality and natural raw materials, we make an important contribution to environmental protection. Ecological insulating materials have nothing to envy of conventional materials. They are becoming increasingly important in the construction sector. Cork, hemp, sheep’s wool or wood – so let’s learn about the properties, areas of use and costs of different natural insulating materials.

How to discard old insulation materials debris

Discarding insulation materials debris requires careful handling to ensure safety and environmental responsibility.

The way to do is to to first identify the type of insulation material you are dealing with, as different types such fiberglass, foam or cellulose have their specific disposal requirements.

For fiberglass insulation, you must wear protective gear such as gloves, goggles, and masks to prevent skin irritation and respiratory issues. The place the debris in heavy-duty plastic bags, sealing them securely to avoid dust dispersion.

Foam insulation, especially if it contains hazardous chemicals, should be taken to a hazardous waste disposal facility. Cellulose insulation, made from recycled paper, can often be composted or disposed of in regular waste, using a dumpster rental service if necessary, but confirm with local regulations first.

After identifying them contact your local waste management company or recycling center for guidance on proper disposal procedures for such materials. Also consider your recycling options, as some insulation materials can be repurposed, reducing environmental impact and promoting sustainability, while others cannot.

Advantages of ecological insulation materials

Like other sustainable building materials, natural insulation stands out because it is particularly environmentally friendly. They can be reused, thermally recycled or even composted without having negative consequences on the environment or on the health of people and animals. This will help with the zero waste target.


The production of natural insulating materials requires much less energy than that of traditional insulating materials. Most natural insulators also do not require the addition of chemicals. Like many other construction materials, they are reusable: the use and recycling of renewable raw materials preserves limited resources.

Safe for our health

Unlike many conventional insulation materials, ecological insulation materials pose no health risks and are suitable for allergy sufferers.

A pleasant indoor climate

Ecological insulation materials are distinguished by their ability to absorb and release humidity. They thus ensure a very pleasant indoor climate and effective protection against heat in summer. Most materials are also flame retardant and not very susceptible to the formation of mold and attacks by insects and rodents.

Ecological insulation: comparison of natural materials

You can carry out almost all ecological insulation measures with natural materials. Thermal insulation, sound insulation or facade insulation, natural materials often have better insulating properties than conventional insulating materials.

Conventional insulation materials cost on average around 10 dollars per square meter, while ecological insulation is a little more expensive. Both for conventional insulating materials and for ecological insulating materials, additional costs for implementation and delivery may be added to the purchase costs themselves. Natural insulators are certainly a little more expensive to purchase, but the quality of the indoor atmosphere, their harmless nature in terms of health and their contribution to environmental protection largely justify this investment.

Ecological wood fiber insulation

Wood as a building material is very widespread and requires less dumpster rental services. This raw material is also ideal as an insulation material. Almost all construction projects can be completed with a suitable product. Insulation based on wood fibers has many positive properties proven through long-term practical experience.

It should be noted that among ecological insulation materials, wood fiber insulation increasingly occupies a leading position in thermal insulation. They are even better suited to protect against heat in summer than other natural materials. Their high density combined with low thermal conductivity and high values ​​of specific heat capacity is the reason. For comparison, an attic insulated with wood fiber insulation panels is on average 6°C cooler in summer than if the ecological insulation was carried out with conventional materials.

Other properties: they are cost-effective, very resistant to humidity and very insulating. Wood fiber insulation has a sound absorption action and can also be used as sound-absorbing elements. Their production, however, requires more energy than that of other natural insulating materials.

Wood chip insulation

Wood chip insulation is made from planing scraps from local softwood trees. The diffusion properties of the material ensure a pleasant indoor climate, while guaranteeing high thermal protection. Eco-friendly wood chip insulation resists rot, mold, vermin and fungus. You can use them as sound and heat insulation as well as blow-in insulation in wooden construction.

As an alternative insulating material, it is also possible to use wood chips under a screed, as an equalizing backfill for walls, pipes, pipe ducts or ceilings with wooden beams. The material does not need to be bonded, it can be installed dry and is immediately walkable.

During manufacturing, the chips are coated with mineral additives or binders, for example clay. After use, you can reuse the natural material, burn it for energy or compost it.
