Metodología y servicios
- What is the working process like with Afandecor?

- Technical analysis: We listen to the needs and assess current conditions.
- Energy and functional diagnosis: if the project requires it, a study of the thermal behavior or use of the space is carried out.
- Customized proposal: from a one-off action to a comprehensive solution.
- Execution with our own personnel: trained installers and continuous technical monitoring.
- After-sales service and maintenance.
- Do you issue energy efficiency certificates?
Yes, if the client requires it, we offer it. - What role does technical advice play in the group's projects?
It's a fundamental part. Our technicians not only install, but also advise on regulations, subsidies, energy efficiency, materials, and compatibility between solutions. This guarantees long-lasting and consistent results. - Can I combine insulation, solar protection, and renewable energy in one project?
Yes, and in fact, it's the most efficient. We combine high-efficiency windows, smart pergolas or awnings, and photovoltaic systems to create an energy-independent home with a low environmental impact.
Sostenibilidad y Eficiencia energética
- Do Afandecor's energy-efficient windows meet the requirements of the CTE (Technical Building Code)?
Yes. All our windows are manufactured according to the Basic Energy Saving Document of the CTE. - How is the quality of a window regulated?
Through European regulations that evaluate profiles, glass, opening systems, and installation. At Afandecor, we only work with manufacturers that meet and exceed these requirements. - What does “high impact resistance” mean?
It's an official rating that indicates a window maintains its shape and properties even with temperature changes or impacts. This is key to the durability of corners and joints. - What level of sound insulation can be achieved?
With PVC profiles like those from Kömmerling and special glass, they can be reduced up to 47 dB from outside noise, achieving a very quiet environment even in noisy areas. - How do they recycle at Afandecor?
Kömmerling removes unused or surplus PVC profile scraps every 21 days, takes them to its factory, grinds them, and removes impurities before reintroducing them into the production process in the form of granules or powder, which are then used to manufacture new systems.
Cortizo, for its part, removes aluminum scrap once a month, and the process is very similar. This material is transported to its recycling plants, where it is melted and converted back into raw material for manufacturing new profiles. Together, we contribute to reducing waste and energy consumption, closing the aluminum cycle. - Does installing energy-efficient windows reduce a home's carbon footprint?
Yes. By reducing the use of air conditioning systems, a direct impact on the reduction of CO₂ emissions, especially if non-renewable energy is used. - How much can you save by installing energy-efficient windows?
The savings can reach up to 30 % in air conditioning, depending on the type of home, its orientation, and the previous system. In some cases, even more so if combined with other improvements to the building envelope.
Instalación y proceso

At Afandecor Ventanas we install Guardia Glass and Saint Gobain (Climalit) glass. - What type of window is better: PVC or aluminum?
Both materials are suitable depending on their use. PVC offers excellent thermal and acoustic insulation and requires little maintenance. Aluminum is more durable and is recommended for large glass surfaces. - Are all PVC windows the same?
No. Although they have a similar appearance, they differ in material quality, profile design, hardware, and sealing system. At Afandecor, we work exclusively with Kömmerling, a German brand with its own advanced formula (Kömalit Z), which incorporates internal metal reinforcements and exceeds the standards required in Europe. - What is thermal break?
It is an insulating layer incorporated into aluminum profiles to prevent the transmission of outside temperatures to the inside. It increases energy efficiency and reduces condensation. - What type of glass is best for the environment?
In most homes, good double glazing is sufficient. For very cold or noisy areas, triple glazing or reinforced soundproof glass is recommended. - How is the required level of sound insulation determined?
It depends on the difference between outside noise and the desired level of silence. A bedroom requires more insulation than a kitchen or office, for example. - Can windows with different levels of sound insulation be installed without changing the design?
Yes. We can install windows with different acoustic configurations depending on the room, without altering the exterior appearance.
