When choosing frames for the home you are building or renovating, the first thing you look for is the reliability of a well-known profile brand. However, a window is much more than just a set of profiles. The true value lies in the quality of the final construction – a process shaped by two key contributors: profile producers (extrusion companies) and frame manufacturers.
What exactly is the difference between them, and how do they work together?
Profile producers (extrusion): Supply of raw materials
Profile manufacturers produce aluminium and PVC systems in standard six-meter lengths. which serve as raw materials for the production of windows and doors. These companies do not manufacture the final products themselves. Instead, their role focuses on:
- ensuring system integrity
- painting or foiling the profiles
- delivering profiles to manufacturers according to the specified schedules
Frame manufacturers: Creation of the final product
Frame manufacturers, such as Thermoplastiki, receive these profiles and transform them into complete window and door systems. This process includes cutting, welding (corner joining), installing mechanisms, glazing, and adding accessories.
While the quality and type of profile are important, the manufacturer ultimately determines the final performance and functionality of the windows & doors. Their responsibilities include:
- selecting high-quality systems and ensuring proper processing
- utilizing advanced production machinery and equipment
- the integrity of the final product
- providing warranties
- ensuring proper installation
- offering after-sales service
Why is it important to know the difference between the two?
Recognizing these distinct roles helps you make a more informed investment decision.
1. Guarantee of final performance
A profile may come with technical specifications, but only a skilled manufacturer can ensure these are fully realized in the final product. Expertise, know-how, and advanced equipment are essential to achieving optimal performance.
Thermoplastiki continuously invests in state-of-the-art machinery, with a strong focus on innovation and quality. Every window & door comes with certificate of authenticity, certifications, and warranties of up to 10 years.

2. Customization and materials
While extrusion companies supply the profiles, a complete frame requires much more: mechanisms, glazing, and expert assembly. It is the manufacturer’s responsibility to carefully select and combine the best materials to meet your specific needs and dimensions.
Thermoplastiki is not only the largest frame manufacturer in Greece, but also produces all-encompassing solutions at its facilities, including:
- double and triple glazing with energy-efficient Sun Plus coating, enhancing performance, aesthetics, excellent thermal insulation, durability, and high-level safety.
- insect screens and shutters, designed to perfectly match each frame.
3. Support
If you need any clarification regarding your frame, you won’t contact the profile producer, you’ll turn to the manufacturer of your frames. In essence, the frame manufacturer is your long-term partner. At Thermoplastiki, every frame is accompanied by its exclusive after-sales benefits.
