FREQUENT QUESTIONS

Yes. All our windows are manufactured according to the Basic Energy Saving Document of the CTE.

Through European regulations that evaluate profiles, glass, opening systems, and installation. At Afandecor, we only work with manufacturers that meet and exceed these requirements.

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.

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.

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.

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.

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.

Window replacement is typically completed within a few hours or within 1 or 2 days, depending on the total number. New windows are delivered pre-glazed; the old ones are removed and installed without the need for extensive construction.

At Afandecor Ventanas we install Guardia Glass and Saint Gobain (Climalit) glass.

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.

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.

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.

In most homes, good double glazing is sufficient. For very cold or noisy areas, triple glazing or reinforced soundproof glass is recommended.

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.
