Wall Insulation
The benefits of wall insulation
A large area in the houses can be the outer walls. Most homes in our neighborhood do not have cavity walls (space between the inner and outer wall), which means that cavity wall insulation is not possible. In theory, you can insulate a solid wall from the outside, but that is usually not allowed near the front in a protected cityscape.
What is a possibility is that you insulate the facade on the inside. This form of insulation provides energy savings of an average of 6m3 gas per year per square insulated wall.
Wall insulation is especially interesting if you have a blank side wall, but it can also be applied to the sections of wall next to and below the windows. Wall insulation is certainly wise if you have insulated the windows in the same wall.
Materials
With wall insulation, a front wall is placed on the inside of the facade with insulation material behind it, such as:
- Reflection blankets
- PIR
- Flax.
Insulation value
The insulation must have an R-value of at least 3.5. R stands for 'Resistance', so the higher the R value, the better the material insulates.
Costs and savings
No target price per square meter can be set for wall insulation. A lot of customization is involved in the finishing of the front wall. The offer is always tailor-made.
At the RVO you receive a subsidy on wall insulation of € 19 per m2. That amount doubles if you take 2 measures.
The gas savings for wall insulation is approximately 6m3 gas per year per square meter of insulation. With the prices of the energy ceiling, this is a saving of € 9 per m2 of insulated wall.
