The Narrow Line Family
The Narrow Line Family is a welded aluminum fenestration system developed by SynComm Windows & Doors, a brand of Synergy Group. The system continues to be developed and expanded in response to project requirements.
All tiers are based on the same construction approach: welded frame and sash assemblies with controlled narrow sightlines, maintained across all configurations.
Narrow line Tier options
- Standard frame depth and sash construction
- Designed for controlled opening sizes
- Dual-insulated glazing
Available configurations:
- Fixed Casement
- Fixed Awning
- Operating Casement
- Operating Awning
- Increased sash dimensions
- Enhanced sash construction for higher weights
- Deeper frame geometry
- Supports triple-insulated and laminated glazing
Available configurations:
- Fixed Casement
- Fixed Awning
- Operating Casement
- Operating Awning
- Side-mounted Casement
- Supports traditional proportions at increased opening sizes
- Supports custom and replicated SDL layouts
- Designed for profile depth and visual accuracy
Available configurations:
- Fixed Casement
- Fixed Awning
- Operating Casement
- Operating Awning
- Side-mounted Casement
- All-aluminum construction
- Supports increased opening sizes
- Supports custom and replicated SDL layouts
- Maintains Narrow Line proportions and welded construction
Available configurations:
- Fixed Casement
- Fixed Awning
- Operating Casement
- Operating Awning
- Side-mounted Casement
System Construction
- Welded aluminum frame and sash assemblies
- Seamless corner execution
- Slim sash profiles maintained across all tiers
- Aluminum-clad exterior with wood interior options, as well as all-aluminum configurations
- Consistent fabrication across all system variants
Configurations
- Fixed Casement
- Fixed Awning
- Operating Casement
- Operating Awning
- Side-mounted Casement (Tier II and above only)
Configuration availability is governed by sash size, weight, and hardware constraints.
Glazing
- Dual-insulated glazing (all tiers)
- Triple-insulated glazing (Tier II and above)
- Laminated glazing (Tier II and above)
- Project-specific high-performance glazing assemblies
Frame depth and sash construction increase across tiers to accommodate larger and heavier glazing units.
Material Options
Alternative metal cladding options are available:
- Bronze
- Copper
- Stainless steel
- Other specialty metals
All material variations are manufactured using the same welded frame and sash construction with consistent detailing.
