The PVC profile is the backbone of a window structure. It defines the window’s shape and dimensions, ensures rigidity, and guarantees the system’s durability. Without a high quality profile, it is impossible to achieve reliable thermal insulation, soundproofing, and airtightness.
Why Is the Profile So Important?
• Structural support. The profile acts as a frame that holds the glass unit and hardware. Its strength determines the window’s resistance to wind loads and temperature fluctuations.
• Thermal and acoustic insulation. The profile contains air chambers that reduce heat loss and block external noise. More chambers mean better insulation properties.
• Airtightness. Seals are attached to the profile to prevent cold air and moisture from entering. The profile’s geometric precision directly affects how tightly components fit together.
• Aesthetics and design. The profile determines the window’s appearance: it can be white, wood effect laminated, or painted in any colour.
• Durability. High quality PVC resists UV radiation, moisture, and temperature swings — it won’t warp, rust, or require regular maintenance.
Additional Components
• Reinforcement (a metal insert inside the profile) adds rigidity, prevents deformation, and enhances burglar resistance.
• Drainage channels in the profile direct condensate away, protecting the structure from moisture.
In summary, the quality of the PVC profile determines key window characteristics: comfort, energy efficiency, and service life. Therefore, when choosing windows, it is essential to pay attention to wall thickness, number of chambers, and the presence of reinforcement.
