System Identity - Thermalbreak AL 420

The AL 420 system is designed for aesthetic appeal, durability, thermal and acoustic insulation, and energy efficiency. It features a distinctive simple external line for brand recognition and anti-imitation. Based on the AL 410 series, it includes polyamide thermal breaks (16-24 mm) and supports glazing up to 37 mm. The system offers a wide range of adaptable profiles and corner connection types, supported by high-quality accessories and backed by ALUMINCO’s warranty.

Advantages of AL 420 System

• Distinctive design identity
• Wide application range
• Two-dimensional polyamide thermal breaks for enhanced insulation
• Innovative internal design lines
• Special door sash profiles
• Profiles with variable angles for construction flexibility

Quality Control Methods

• Extrusion Tolerances: ±0.40 mm for critical dimensions
• Straightness: Max 3 mm deflection on 6 m bars
• Warping: Max 2 mm on 5-6 m profiles
• Electrostatic Painting: Visual inspection from 2 m distance (QUALICOAT standard is 3 m)

General Catalogue - Profiles Summary

The catalogue details AL 420 system profiles with codes, shapes, weights (269 gr/m to 2200+ gr/m), moments of inertia and resistance, descriptions, and standard 6 m lengths. Profiles include frames (small to large, straight and curved), sash profiles for windows and doors, transoms, adapters, and accessories. These support diverse architectural applications ensuring structural integrity and design flexibility.

Profile Specifications and Applications

• Profile Codes: Unique identifiers linked to specific applications (e.g., shutter blinds, frames, sashes)
• Weights: Range from ~117 gr/m to over 2200 gr/m depending on profile size and complexity
• Dimensions: Standard length 6 m; outer perimeters vary widely
• Structural Parameters: Moments of inertia and resistance provided for mechanical performance
• Profile Types: Shutter profiles (single/double), frame profiles (small to large, with thermal breaks), sash profiles (straight/curved), transoms, adapters, and variable angle profiles

Beads for Glass

• Designed to secure glass panes with gap sizes from 12 mm to 37.8 mm
• Weights approx. 181 gr/m to 335 gr/m
• Essential for glazing installation and compatibility with glass thickness

Thermal Breaks

• Polyamide thermal breaks of 16 mm or 24 mm thickness integrated into profiles
• Critical for reducing heat transfer and improving energy efficiency

Key Parameters and Limitations

• Weight per meter affects structural calculations and handling
• Outer perimeter important for component compatibility
• Moments of inertia and resistance essential for load-bearing capacity
• Standardized 6 m lengths facilitate modular construction

Best Practices and Recommendations

• Select profiles based on application needs considering mechanical and dimensional properties
• Use beads matching glass thickness for secure glazing
• Incorporate thermal break profiles to enhance insulation
• Consult structural parameters for design safety

Construction and Maintenance Guidelines

• Familiarity with profiles and appropriate construction solutions required
• Maintain 2.5-3 mm clearance around frames for installation and insulation
• Accurate cutting and grooving with anti-corrosion protection on cut edges
• Sealant application at joints for watertightness and drainage
• Drainage holes in shutter leaves to prevent corrosion
• Use only catalog-listed mechanisms and accessories
• EPDM sealing gaskets recommended for durability and easy replacement
• Proper glass support to avoid frame sagging
• Technical assistance advised for complex constructions
• Regular cleaning with mild detergent and water; avoid abrasives and solvents
• Remove protective film immediately after installation
• Use special adhesives on damaged paint areas to prevent corrosion

Installation Instructions for Tilt-and-Turn Security Lock Mechanism
