Additional insulation with blown wool

As heating energy has clearly become more expensive, additional insulation is a profitable investment.  Insulating the attic is often the most energy-efficient measure to control heating costs. In addition to reducing heating costs, additional insulation will improve the comfort of living in the building, the resale value of the house and it will make your house more ecological.

Often the room temperature is raised as soon as the draft is felt, or the floor feels cold. However, energy consumption will increase significantly even if the room temperature is only increased by a few degrees. Excessive heating not only increases your heating costs, but also causes unnecessary carbon dioxide emissions, so you can reduce your carbon footprint and save the environment by providing sufficient thermal insulation.

As the heat tends to rise upwards, proper insulation of the attic plays a key role in the temperature of the building. Especially in older houses, thermal insulation is often less effective than in newer buildings. In the past, industrial by-products, such as sawdust or cutter shavings, may be used as insulators, which will diminish over time. Even in newer buildings, the insulation may be deficient, so it is a good idea to check the need for additional insulation in attic first. Extra insulation is most easily done with a blown wool that can be fitted everywhere. A new layer of insulation may be blown over the old demolition insulation. Blown wool can be used as an additional insulation over any previous insulation below. If the insulation has become wet due to roof leakage for example, it is advisable to remove it before installing a new insulation layer. The total thickness of the sufficient insulation on the top floor is approximately 400-500 mm.

Additional insulation for floors

Cold floors are usually due to poor insulation. Previously, the floors were insulated with chips, moss or other loose insulations, which have also been sunken over time. Due to the collapse of the insulation, an empty space has formed between the insulation and the floor. This space absorbs cold outdoor air, which cools the entire floor. The most effective way to insulate the floor is to "inject" the blown wool into the empty space. The insulation begins by drilling a small hole in the floor from which a small cable camera is inserted into the empty space between the floor and the insulation. The camera can be used to find out the actual situation of the insulation and the size of the space to be filled. Next, a thin blow pipe is inserted into the drilled hole to blow the blow wool into the empty space.

Another option for additional floor insulation is to demolish the floor and fill the insulation with blown wool. However, demolishing a floor is a time consuming and much more demanding process than insulating through a floor opening.

Insulation may be added under the ventilated crawl space, if there is sufficient working space. Additional insulation on the crawl space will help if the original insulation space is completely filled and the floor has good air and wind tightness.
