How to insulate a house ecologically?

Are you also worried about the safety of your home? Then some needs will bother you because sometimes it is necessary to insulate your home and do energy and energy renewal work.

Poor insulation is the cause of significant heat loss in all homes nowadays. Doing so with ecological materials can be a plus point. There are many eco-insulators on the market today, each with a different application.

So how do you keep a home ecologically safe? Insulating your walls, floors, and attic with sheep’s wool, wood fiber, or even hemp wool is an effective solution to ecologically insulating your home.

So now you read carefully these new ecological insulation materials mentioned by us and make your home ecologically safe.

How to insulate a house ecologically?

To protect your home ecologically, it is possible to choose natural thermal and acoustic insulation. For this, depending on your use, we have included the best 3 most used ecological insulation materials that may be suitable for you.

  1. Wood fiber
  2. Sheep’s wool
  3. Hemp wool

Now that you know your different options, we invite you to discover the insulation that best suits the nature of your energy renovation work.

1. Wood fiber: for walls and floors

Wood fiber is a natural and ecological insulating material. Indeed, fully recyclable, wood fiber panels are made from the defibration of resinous tree scraps.

With a thermal conductivity of 0.037 W/mK at its lowest, wood fiber offers excellent protection against heat in summer and against cold in winter. Available in the form of semi-rigid or rigid panels, this ecological insulation is ideal for insulating walls and floors.

Indeed, due to its porous structure, wood fiber panels effectively protect against noise inside homes. In addition, its density protects it from thermal phase shift: the panels do not sag over time.

Durable and ecological, wood fiber is a particularly interesting solution for insulating walls and floors. However, wood fiber is more expensive than other insulation: the price per m2 varies between $20 and $50.

2. Sheep wool: for attics and ceilings

Sheep wool is an insulator of animal raw materials. Sheep hair is the only thermal insulator produced as such by nature. Indeed, they have the ability to adapt to the climate and temperature variations.

In this sense, sheep’s wool naturally protects against cold and humidity. In bulk or in rolls, sheep’s wool is particularly recommended for attics and ceilings, particularly for its lightness.

With a thermal conductivity coefficient of 0.035 W/K to 0.050 W/K, it insulates your home from cold and heat, depending on the seasons. In addition, sheep’s wool insulation resists fire well, only igniting from 560°C.

Sheep’s wool is made from almost 100% natural material. Also, it is completely compostable and does not cause damage to the environment, which makes it an ecological insulator.

On average, a 60 mm thick sheep’s wool panel costs $20 to $25/m². Sheep wool is generally more expensive than other natural insulation materials.

3. Hemp wool: for roofs and floors

Hemp wool is a material made from natural fibers packaged in the form of loose insulation, rolls, or panels. Hemp is also one of the only field plants that does not use any herbicides, insecticides, or fungicides.

Which makes it an option perfectly suited to your ecological energy renovation work. Hemp wool has a thermal conductivity that varies depending on its composition and packaging from 0.039 to 0.050W/mK.

In addition to offering efficient thermal insulation, its fibrous composition also provides sound insulation for the walls. In addition to being non-allergenic and not releasing dust, hemp wool offers great versatility in terms of use (floors, walls, attics, roofs).
