Proper preparation of the walls for insulation and proper implementation can save us a lot of unpleasantness in the future. But what if we insulate the walls of the house incorrectly?
Poorly insulated walls of our new home can lead to a number of problems that can affect both the comfort of the occupants and the durability of the building itself. After all, building a house is a dream for many people, but poorly executed construction work can quickly turn that dream into a nightmare. If we insulate the house badly we can expect high heating bills or poor sound insulation.
Poorly insulated walls in a new home may seem like a minor oversight, but in reality they are a much bigger problem than they might seem at first glance. Higher heating bills, uncomfortable indoor temperatures, dampness or fungus growth are just the tip of the iceberg. A home that was supposed to be a haven of peace and a dream for years to come can quickly turn into a source of frustration and additional expenses.
Proper thermal insulation is not only a matter of energy efficiency, but also the health and safety of users. Modern construction standards place great emphasis on the elimination of thermal bridges, which are the main cause of heat loss, but proper execution requires knowledge, experience and attention to every detail. That is why it is so important to entrust this task to professionals who will take care of the precision of workmanship and the use of appropriate materials.
Problems beget problems
Poorly insulated walls – surprisingly – mean a lot of heat loss. If the thermal insulation is not done properly, heat will quickly escape to the outside in winter, and in summer the high temperature will set in our rooms in no time. The heating season can turn out to be dramatic in terms of heating costs. Such errors in insulation may not be noticeable at first glance, and their effects will be felt only after the first heating season, when much higher bills hit the table.
Thermal bridges – how important are they?
A hidden danger is thermal bridges. These are invisible places through which heat easily escapes. These seemingly small deficiencies during insulation can lead to uneven heating of the interior, cooling and further heat loss. Cold spots also promote condensation inside our wall, which leads to another problem.
These small, seemingly innocuous deficiencies in the insulation of our exterior walls have a huge impact on the overall effectiveness of a building’s thermal insulation. Thermal bridges result in heat from inside the building easily escaping to the outside and cold air entering the interior. This means higher heating bills, because the heating system has to work harder to maintain the right temperature indoors. There is also uneven heating of the interior through these points, which can lead to perceived discomfort for the occupants.
The heat transfer coefficient (U-factor) is one of the most important parameters that determine how effectively a wall, roof or windows protect against heat loss. A high U-factor tells us that heat flows more easily through an element, which means more energy loss and higher heating costs. That’s why it’s so important that all building elements are properly insulated and have a low U-factor, especially in sensitive areas where thermal bridges often appear due to inadequate insulation.
Moisture not only in the walls
Inadequate insulation is precisely what promotes condensation on the interior surfaces of the walls. The mold that develops not only damages the walls, but also has a serious impact on the health of homeowners. Regular moisture and mold problems can be difficult to eliminate. As water vapor turns into moisture and enters the walls, it not only contributes to the deterioration of the air quality in the house, but also further weakens the building structure. Mold and fungi have the ability to penetrate deep into building materials, causing permanent damage. As a result, the walls become less stable, which in extreme cases can lead to the need to replace structural elements.
Moisture often enters the walls due to poor workmanship, the selection of inadequate insulation thickness or the use of the wrong material, which is linked not only to mold, but also to faster building deterioration. An improperly insulated house becomes much more susceptible to a number of other problems, such as cracking of plaster, weakening of walls or even corrosion of metal components that are part of the building structure. Over time, it also weakens the foundations and other load-bearing elements of the building, which can lead to costly repairs and further difficulties in maintaining proper building stability.
The renovation in such a case is costly, can take months, and – even worse – does not always bring long-term solutions. Often it is necessary to carry out not only plaster repairs, but also thorough measures to replace damaged structural elements and protect the entire building from further moisture. The replacement of thermal insulation can be complicated and time-consuming, as it involves the demolition of parts of the walls, as well as the repair of damage from previous moisture. Such work consumes a lot of money, and on top of that there is a risk that moisture problems will return if the original insulation errors are not properly addressed.
The facade, with poorly executed insulation, can become deformed, cracked and even develop efflorescence and stains. This not only spoils the appearance of our house, but can later lead to further structural damage.
Don't take any chances
We practically already know the answer to the title question. Poorly executed insulation leads to numerous problems and complications. The entire insulation structure may require costly replacement, which will consume a considerable amount of budget and time. We can be protected from this by a general contractor such as Energetic Design, which takes all the responsibility.
In addition to building homes from the ground up, Energetic Design has been involved in home thermal upgrades for years and has successfully insulated buildings to restore them to their former glory. A rigorous approach to preparing the substrate, choosing the right insulation materials and proper workmanship is the key to insulating the Our dream house in accordance with the art.
