PVC Window Construction: Key Components and Their Functions

General Structure of the Window System

Modern PVC window is a complex engineering structure consisting of several interconnected components. Each element performs a specific function, ensuring reliability, tightness, and durability of the entire system.

Main Frame Components

Profile system serves as the foundation of the window. It consists of:

• External and internal profiles
• Reinforcing metal insert
• Thermal insulation chambers
• Drainage channels

Glazing Unit as a Key Element

Glazing unit is the most important part of the window, responsible for thermal and sound insulation. It includes:

• Glasses of various thicknesses
• Spacer bar
• Molecular sieve for moisture absorption
• Sealing gaskets

Hardware and Opening Mechanisms

Window hardware ensures the functionality of the window:

• Hinges for sash attachment
• Locking mechanisms
• Turning handles
• Blockers and anti-burglary elements
• Micro-ventilation systems

Sealing Systems

Seals guarantee the tightness of the structure:

• Primary seal between the frame and sash
• Secondary seal around the perimeter of the glazing unit
• Tertiary seal at profile connection points

Additional Elements

Auxiliary components enhance the functionality of the window:

• Drainage holes for moisture removal
• Water drainage channels
• Ventilation valves
• Decorative trims
• Mosquito screens

Installation Features

Installation kit includes:

• Fastening elements
• Mounting foam
• Sealing tapes
• Reveals and sills

All components of the construction must be compatible with each other and meet quality standards. Proper selection of components and professional installation ensure the longevity and efficient operation of the window system throughout its service life.
