Energy-efficient renovation in old buildings is becoming an increasingly important topic, especially in times of rising energy costs and growing climate protection requirements. Many old buildings are not well insulated and lose a lot of heat, leading to high heating costs and unnecessarily high CO₂ emissions. For property owners, the question arises: How can an old building be brought up to date in terms of energy efficiency, and is it possible to carry out such a project without much prior experience? In this article, we will address these questions and show how FRIEDWIL FX5 insulation foil can play a key role.
Why is energy-efficient renovation in old buildings so relevant?
Many old buildings have their own charm but are often problematic in terms of energy efficiency. They were built in times when thermal insulation and energy efficiency were not a priority. This means they are often poorly insulated, leading to heat loss through walls, roofs, and windows. As a result, energy consumption is high, and homeowners spend unnecessarily large amounts on heating costs.
At the same time, climate protection requirements are increasing, and the government mandates through its Building Energy Act (GEG) that houses be modernized in terms of energy efficiency. Those who implement these measures not only save energy costs in the long term but also increase the value of their homes. Modernized and energy-efficiently renovated old buildings are much more attractive and future-proof on the real estate market.
What should property owners consider in energy-efficient renovation?
When undertaking an energy-efficient renovation in an old building, there are several key points homeowners should consider to successfully implement the project:
- Inventory analysis: First, it must be determined where the old building has the greatest energy weaknesses. These could be poorly insulated exterior walls, an uninsulated roof, or outdated windows. An energy consultant can help identify the right renovation measures.
- Insulation: A central aspect of energy-efficient renovation is insulation. It is important to choose the right insulation technique. An easy way to insulate walls and the roof is to use reflective insulation like FRIEDWIL FX5. This insulation is not only particularly thin and space-saving but also easy to handle, making it ideal for homeowners who want to carry out renovation projects themselves.
- Heating and ventilation: In addition to insulation, heating plays a crucial role. Outdated heating systems should be replaced with modern, energy-efficient models. Ventilation in the building should also be considered, as good ventilation improves indoor air quality and prevents mold growth.
- Take advantage of funding: Those who carry out energy-efficient renovations can benefit from government funding programs, such as the Federal Funding for Efficient Buildings (BEG). This program offers grants or low-interest loans for many measures, from insulation to the installation of modern heating systems.
Can energy-efficient renovation be done without much prior experience?
Many homeowners wonder if they can tackle a large project like the energy-efficient renovation of an old building without any prior experience. The good news is: Yes, in many cases, it is possible. The key lies in choosing the right materials and thorough preparation.
While some renovation measures, such as replacing a boiler or installing a complete ventilation system, require expertise and the support of professionals, there are many tasks that DIY enthusiasts can handle on their own. Insulation is a particularly important area, and there are modern solutions specifically designed to be easy and quick for homeowners to install themselves.
Implementing insulation on your own
FRIEDWIL FX5 insulation foil is a great example of insulation material that is particularly easy to work with. Thanks to its slim thickness of only 2 cm, it is ideal for old buildings where there is often little space for thick insulation materials. What really sets this insulation foil apart is its user-friendliness: It can be easily cut to size and installed on walls, roofs, or under floors. You don’t need any special tools or professional knowledge to install the insulation. All you need is a utility knife, a measuring tape, and some basic DIY skills.
The biggest advantage of FRIEDWIL FX5 is its integrated reflective layer, which reflects heat back into the room rather than absorbing it. This reduces the building's energy consumption without the need for complex technical procedures. Additionally, the foil’s micro-perforation allows the wall to breathe while regulating moisture. This function as a mild vapor retarder helps prevent mold growth—a particularly important point in old buildings, which often suffer from moisture problems.
Even if you have little experience in construction and renovation, you can achieve quick and visible results with products like FRIEDWIL FX5. Since the foil is available in practical roll formats, you can also carry out the project step by step, insulating rooms one by one. This allows you to maintain control over time and budget.
Why energy-efficient renovation in old buildings is worthwhile
Energy-efficient renovation in old buildings offers numerous advantages. First, you save on energy costs in the long term, as less heat is lost and you need to heat less. Second, you increase the value of your home, as a modernized and well-insulated building is much more in demand on the real estate market. Lastly, with energy-efficient renovation, you contribute to climate protection by reducing your home's CO₂ emissions.
Many measures are eligible for government funding, which can significantly reduce the cost of renovation. In addition, with materials like FRIEDWIL FX5 insulation foil, you can tackle the work yourself, making your home more energy-efficient step by step, even without extensive prior knowledge.
