What are the advantages of uPVC windows and doors:

1. Number One in energy efficiency.

The frame of a window plays a decisive role in promoting energy and cost-efficient thermal insulation. Window and door profiles made of uPVC score top marks when compared with aluminium or wooden windows. They have better insulation values and are able to reduce energy and heating costs. There is a particularly high energy saving potential when using uPVC window frames in the passive house standard. Today, passive house windows and doors can be manufactured efficiently and cost-effectively using state-of-the-art uPVC profiles and the now quite common triple glazing.

2. Very good cost-benefit ratio.

uPVC windows and doors offer clear-cut cost advantages, both in procurement and throughout the entire life cycle. Timber frames are approximately 20-30 % more expensive than uPVC profiles, and aluminium cost 30 % more again representing the most expensive alternative. Based on the high energy-saving potential and minimal maintenance throughout the entire service life of more than 50 years, costs are also saved in the long-term.

3. Minimal maintenance.

High quality uPVC windows are extremely easy to care for and require minimal maintenance. Wooden windows, on the other hand, have to be glazed just about every two years and painted every 5 years. State-of-the-art uPVC granule is extremely resistant to weather conditions and light-fast. To clean the window frames all you need is dishwashing liquid due to the easy-care properties of the smooth profile surfaces.

4. uPVC windows and doors are remarkably durable.

As opposed to windows and doors made of wood, uPVC windows and doors have a particularly long service life. High quality windows stand out with their distortion resistance and high level of functionality for years and years. Based on their long service live of at least 50 years PVC windows are an excellent investment, also with regard to maintaining a property’s value.

5. Excellent eco balance.

uPVC windows and doors are 100% recyclable and therefore resource-saving. 40% of all gas and oil reserves in the world are used for heating and for supplying energy to buildings, whereas just 4% go into the production of plastics of which just 1% are used for uPVC. Besides being recyclable, the durability and low levels of pollution during the production of uPVC profiles help produce an excellent eco-balance and contribute towards protection of the environment. uPVC windows and doors last much longer than wooden and consume substantially less energy during the manufacturing process.

Not all uPVC windows are created equal.

Windows made from the latest generation of GEALAN profile systems not only look attractive, the sophisticated profile geometries have also been perfected right down to the last detail to satisfy all technical requirements.
