PVC Windows – Quality and Efficiency in Lisbon and Portugal

Windows are one of the most important elements for comfort, security, and energy efficiency in any property. We work with high-quality PVC windows, ensuring thermal and acoustic insulation, as well as a modern and functional design.

Tipos de Janelas

Tilt-and-Turn Window

The tilt-and-turn window is a versatile type of opening used in many modern buildings. It has two modes of operation: it can be fully opened inward like a regular casement window (tilt mode) or tilted at the top to allow ventilation without fully opening (tilt and turn mode).

This system is made possible by special hinges and a locking mechanism that allows switching between modes with a single handle. The tilt mode is ideal for safe ventilation, while the turn mode facilitates cleaning and the entry of fresh air. This type of window combines functionality, security, and comfort.

Price:

  • Tilt-and-Turn Window (800×1200) from €140 + VTA for window.
  • Tilt-and-Turn Window (1500×1100) from €250 + VTA for window.

Casement Window

The casement window is a type of window that opens outward or inward through side hinges. It provides good ventilation and efficient sealing against wind and rain. It is common in residential buildings and can have one or two sashes.

Price: Casement Window (800×1200) from €130 + VTA for window.

Tilt Window

The tilt window (ventilation opening window) is a model that opens by tilting the top inward, while the bottom remains fixed. This system allows controlled air entry, ensuring ventilation without compromising security.

The opening mechanism uses bottom hinges and a locking system at the top, activated by a handle. This type of window is ideal for bathrooms, kitchens, and other areas where airflow is essential without needing to fully open.

Price: Tilt Window (500×500) from €80 + VTA for window.

Fixed Window

The fixed window is a model that does not open. Its main purpose is to allow natural light entry and offer an external view without compromising the structure with hinges or opening mechanisms.

Since it has no moving parts, it offers excellent thermal and acoustic insulation, as well as being safer and more economical. This type of window is ideal for places where ventilation is not necessary, such as large facades, corridors, or spaces with other ventilation sources.

Price: Fixed Window (800×1200) from €70 + VTA for window.

Our Projects

PVC windows control the entry of light and heat, helping to maintain a cooler and more pleasant room temperature. This not only provides greater thermal comfort but also contributes to reducing energy consumption, especially in the use of air conditioning or ventilation systems. Additionally, PVC is a durable, resistant, and low-maintenance material, making these windows an economical and eco-friendly choice in the long run. By opting for PVC windows, you will be investing in a more sustainable and energy-efficient environment.
