How the Value Score works:
- Cost Efficiency: Measures noise reduction per pound spent (lower cost per dB = higher score)
- Installation Ease: Considers difficulty of installation and maintenance requirements
- Aesthetic Quality: Rates visual appearance, clarity, and how well it blends with existing windows
- Performance: Overall noise reduction capability and thermal insulation
Adjust the weight sliders to match your priorities. For example, if budget is your main concern, increase the Cost Efficiency weight. If you want maximum noise reduction regardless of cost, increase the Performance weight.
