Roof windows play a fundamental role in any usable attic. They are not only a source of natural light and ventilation, but also have a huge impact on thermal comfort, acoustics and interior aesthetics. Choosing the right type of roof windows is a decision that requires consideration of many factors, such as material, design, technical parameters and functionality. On the market there are windows made of different materials, among which the most popular are PVC and wooden models. In this article we will look at the differences between PVC and wooden windows, their applications and the key features that determine their functionality and aesthetics.

Technical parameters of PVC windows
Windows made of PVC, such as the OKPOL IGOV N22 model, have gained a lot of popularity in recent years due to their exceptional performance characteristics. Polyvinyl chloride is a highly durable material, resistant to moisture, changing temperatures and UV radiation. This makes PVC windows particularly suitable for rooms with high humidity, such as kitchens and bathrooms, where moisture and water vapor can affect the construction of woodwork. The IGOV N22 model is designed for energy efficiency and durability in harsh environments. Its argon-filled triple-glazed glazing package and two warm inter-pane frames provide excellent thermal insulation and minimize the risk of thermal bridges. With a Uw heat transfer coefficient of 0.83 W/m²K, this window meets the requirements of modern energy-efficient construction.

Technical parameters of wooden windows
In contrast, wooden windows, such as the ISOV I22 model, are a choice that combines natural beauty with modern technologies. Wood has been valued for centuries for its aesthetic and insulating properties. The ISOV I22 uses laminated wood, which provides high strength and resistance to deformation. The surface of the wood has been varnished, which protects it from moisture and UV radiation, increasing its durability. This model also features a triple-glazed glazing package, giving it a thermal transmittance of 1.06 W/m²K. Although this value is slightly higher than that of IGOV N22, it falls within the standards for modern roof windows, moreover - like the window made of PVC it qualifies for the government's Clean Air program. Natural wood gives interiors a unique character, harmonizing with traditional and modern arrangements.

Similarities and differences
One of the main differences between PVC and wooden windows is their resistance to moisture. PVC windows, such as IGOV N22, are completely resistant to water and steam, which makes them ideal for bathrooms, kitchens and other rooms with high humidity. Wooden windows, on the other hand, despite the use of protective varnish coatings, require more care and maintenance, especially in rooms exposed to water. For this reason, wooden windows are more often chosen for bedrooms, living rooms or studies, where conditions of use are more stable.

Aesthetics and durability
In terms of aesthetics, wooden windows have an advantage over PVC models, as the natural structure of wood gives interiors warmth and elegance. Windows such as ISOV I22 blend in perfectly with interiors maintained in classic, rustic or Scandinavian style, but also in modern arrangements they are a striking accent. PVC windows, on the other hand, although less decorative, are distinguished by their modern, minimalist appearance and versatility, so they fit into most interiors. Their white, smooth surface is easy to clean and requires no additional maintenance.
Another aspect to consider when choosing between PVC and wooden windows is their durability and resistance to weather conditions. PVC windows are virtually indestructible in terms of resistance to moisture, corrosion and varying temperatures. This makes them particularly suitable for buildings located in harsh climatic conditions, where windows are exposed to intense rain, snow or sun. Wooden windows, while also durable, may require periodic maintenance, such as painting or varnishing, to maintain their properties and appearance.

Roof window functionality
In terms of functionality, both the IGOV N22 and ISOV I22 offer similar solutions to enhance comfort. Both models feature a pivoting system that allows the sash to rotate 180 degrees, making it easier to clean the outer pane. The micro-tilt function allows precise adjustment of the airflow, which is particularly useful during transitional periods, when full opening of the window can lead to cooling of the room. In addition, both models are equipped with ventilators that provide a constant supply of fresh air, even when the window is closed. The differences are mainly due to the frame material and their performance characteristics, making each model more suitable for specific applications.

When installing roof windows, regardless of the material, proper sealing and thermal insulation around the frame is extremely important. Ready-made insulation frames and flashings, such as those offered by OKPOL, allow quick and efficient installation that minimizes the risk of thermal bridges. It is also worth remembering that the correct installation of windows is crucial to their energy efficiency and durability, so care should be taken to ensure precision and the use of high-quality materials.

Summary
In summary, the choice between PVC and wooden windows depends on individual needs, aesthetic preferences and conditions of use. Models such as OKPOL's IGOV N22 and ISOV I22 offer solutions for different requirements, combining modern technology with high quality workmanship. PVC windows are the perfect choice for those looking for durability, ease of maintenance and resistance to moisture, while wooden windows are the ideal solution for those who appreciate the natural beauty and unique character of wood. Both types of windows, with their advanced insulation parameters and functionality, are an excellent choice for modern attic spaces, providing comfort, energy efficiency and aesthetics for many years.
