Design Consistency
The Slimline Fixed Light integrates seamlessly with the full Futura+ system:
- Different colour glazing beads – mix and match to suit your style
- Ideal for multi light elements – achieve large glazed areas with uniform slim sightlines
- Perfect for floor to ceiling glazing, feature windows and large screen effects.
By using a different coloured glazing bead on Futura+ windows and doors, you can achieve a distinctive slimline look that matches the fixed light windows. Opting for a black bead creates an even slimmer appearance
