Saving heating by fixing the facade

The building envelope is the skin that protects us from the climate. If this skin fails, heat escapes in winter and enters in summer, increasing air conditioning costs. Energy rehabilitation through ventilated facade has become the most effective intervention to reduce gas and electricity bills.

How the ventilated facade works

The system consists of fixing a second skin to the building, leaving an intermediate air chamber. In this chamber, the “chimney effect” is produced: the hot air rises and is renewed, preventing heat accumulation in the wall.

Direct benefits:

–
Winter: The insulation glued to the wall retains the interior heat.
–
Summer: Solar radiation hits the exterior panel and not the wall, keeping the house cool.
–
Moisture: Eliminates condensation and interior mold stains.

Energy savings data

Improving the thermal insulation of the exterior facade has an immediate impact on consumption.

Type of House	Heating Savings	Savings in Air Conditioning
Single-family detached	30% – 40%	35%
Block of apartments (old)	40% – 50%	45%
Pre-owned building	20% – 25%	20%

Materials and aesthetics

In addition to efficiency, the building gains market value for its renovated appearance. If you are looking for quality materials, visit this architectural panel factory.

The use of composite allows modern finishes that do not age. The investment in thermal insulation of the exterior facade pays for itself month after month with the reduction of energy bills.

Conclusion

Fixing the facade is not an expense, it is a financial and comfort investment. Living in a thermally stable house improves quality of life and health.

Frequently asked questions about thermal insulation of exterior facade

How long does it take to amortize the work?
Depending on the climate zone and the price of energy, the return on investment is usually estimated between 5 and 8 years.

Are square meters lost inside the house?
No. As it is an exterior insulation (SATE or Ventilated Facade), the usable space of the house is not reduced, unlike the interior walls.

Do all neighbors need to agree?
A simple majority in the community of owners is required, since it is considered a necessary energy efficiency improvement work.

Are there any subsidies for this?
Yes, there are usually European funds (Next Generation) and state or regional aid for the energy rehabilitation of residential buildings.

What thickness of insulation is used?
It depends on the area. In medium climates, rock wool or polystyrene of between 60mm and 100mm thickness is usually installed in the air chamber.

Does the work bother tenants a lot?
Less than an interior renovation. The operators work from scaffolding on the outside, so it is not necessary for them to enter the houses.
