Additional insulation of facade and exterior wall

Additional insulation of facade and exterior wall


Many old houses have a rather poor insulation in the walls. It generates huge energy losses when the house is heated, leading to major electricity costs. But even if additional insulation is good from an energy point of view, it is not as popular to add-insulate the walls of the house as it is to insulate a roof. The reason is simple An additional insulation of the walls of the house is a rather extensive and expensive story. The natural thing is to insulate the walls when the facade needs to be refurbished, thus turning two flies into a bang by also getting better heat efficiency in the house.

Changed appearance

By insulating the outside of the house, a house's appearance can change dramatically . In the worst case it can look hangy and glossy. But you can also take care of changing the facade of the house, thus giving the house a remarkable facelift. However, if a facade is to be replaced, it is very advisable to take care to also insulate the walls. It generates a big saving yearly in heating costs.

Expensive

Many people are more than happy to add a house to the house until the facade needs to be replaced. It's because it's an expensive deal. Therefore, it is not the first recommended for reducing energy costs for heating. Instead, it is a matter of taking care to reduce energy costs when a house still needs a new facade. However, it is very suitable because about 18% of the heat contained in the house disappears through the wall.

Thickness

It is not easy to answer how thick an additional insulation on the house should be. It depends on how the house looks, how the windows are mounted and how the roof foot is placed. Older, non-insolubilized earlier, often have an insulation thickness of 100-150 mm. It is comparable to today's modern houses, which often have an insulation thickness of 300 mm. The most common insulation materials for insulation of outside houses are insulation boards. Mineral wool and glass wool are most common even if there are other alternatives.

Inside or out of

With regard to moisture and, in particular, space, it is often recommended to insulate a house on the outside of the walls. It is possible to add insulation on the inside, but it can be risky. In some cases, especially if the house has a spectacular character or a beautiful and older look, it may be a good option. However, it is important to look out for moisture problems, as the old outer wall becomes colder than before. In turn, it can lead to rot and mold and cause major health problems for both homes and residents.

Material

The type of insulation chosen is largely a matter of taste. On the other hand, building technology is required to be adapted to the insulation requirements, so that insulation becomes efficient and sustainable. Insulation materials have different characteristics. Some are so-called fibrous materials and these should definitely not be blown. They then give a poor insulation effect. Fiber insulation on the wall requires windproofing in all directions. On the other hand, the cellular plastic is a closed material, which means that it only needs windproofing at joints.

Think about

Calculate the thickness of the insulation needed carefully based on the actual insulation requirement and how the appearance of the house is affected by the insulation. The best way to isolate a house depends on what the fa├žade consists of. Please hire a specialist for assistance with the work. Keep in mind that it is possible to change facade cladding when insulation is applied. For example, an old wooden house can be clad with a bevelled facade for a fresher and more fresh look. Do not forget to apply for a building permit if major changes to the house look are to be carried out.
