Effective wall insulation for lower energy consumption and greater comfort – interior insulation with insulating wallpaper and insulation boards
Why is interior insulation so important?
Interior insulation plays a crucial role in optimising the energy efficiency of buildings. Interior insulation offers a valuable solution, especially in older buildings where exterior insulation is often not possible or too costly for various reasons. It helps to minimise heat loss through the walls, ensuring that rooms heat up more quickly. This not only has a positive effect on room comfort, but also on energy consumption, as less heating energy is required to achieve a comfortable temperature. Effective internal insulation also helps to reduce moisture and mould growth, which in turn improves air quality and the indoor climate.
Advantages of interior insulation in detail
Interior insulation offers a number of advantages that make it a popular choice for improving energy efficiency:
- Rapid heat generation: As the insulation materials are applied directly to the interior walls, heat is returned to the room more quickly. This provides an immediate improvement in room temperature. Increased comfort: Good insulation prevents cold bridges and ensures a consistent room temperature, which increases well-being.
- Energy savings: Reduced heat loss can significantly lower heating costs. Heating output can be significantly reduced, especially in well-insulated rooms.
- Easy installation: Internal insulation can be installed quickly and easily, without the need for complex construction work or scaffolding.
- Preservation of the exterior façade: In contrast to external insulation, the external appearance of the building remains unaffected, which is particularly advantageous for listed or aesthetically valuable buildings.
Preventing heat loss – how it works
Heat loss occurs primarily through uninsulated exterior walls, through which the heat in the room escapes to the outside. Internal insulation acts as a barrier here and prevents heat from being quickly transferred to the colder wall surfaces. Materials such as insulating wallpaper or insulation boards significantly improve wall insulation. These materials reflect the heat back into the room, preventing the temperature from dropping quickly. Vapour barrier and vapour control layers are particularly effective, as they prevent moisture from penetrating and thus also prevent mould growth. This leads to better energy utilisation and improves the quality of life in the room.
Cost comparison: internal insulation vs. external insulation
The choice between internal and external insulation depends on various factors, with cost playing a particularly decisive role:
Cost of external insulation: External insulation is generally more expensive as it requires extensive construction work. This includes attaching insulation materials to the façade, using scaffolding and possibly replacing windows or doors. Costs can also increase due to the need for permits or adaptations to listed buildings.
Cost of internal insulation: In comparison, internal insulation is more cost-effective. It does not require any major construction work as it can be installed directly on the interior walls. The absence of scaffolding and complex façade work also leads to lower overall costs. In addition, many systems can be installed by homeowners themselves, saving additional costs.
Long-term savings: Both insulation methods result in significant energy savings, but internal insulation often has the advantage of paying for itself more quickly, as installation is cheaper and the savings in heating costs are immediately noticeable.
Sustainability and durability: While external insulation generally has a longer service life, internal insulation is still an efficient and sustainable solution, especially in cases where external insulation is not possible for structural or financial reasons.
Flexibility: Internal insulation offers greater flexibility as it can also be retrofitted in individual rooms or floors. In contrast, external insulation often requires extensive renovation of the entire building.
The cost comparison shows that internal insulation is an attractive, quick and cost-effective solution for improving energy efficiency for many homeowners.
Reasons for choosing internal insulation
✔ Can be installed at any time, regardless of the weather
✔ Lower costs compared to external insulation
✔ No scaffolding is required, which further minimises costs and preserves the appearance of the façade
✔ Extreme savings potential
✔ Rooms can be heated very quickly
