What Affects Aluminium Window Prices in Kenya?

Not all aluminium windows cost the same — here’s why pricing differs:

1. Type of Window

Different window designs require different profiles and hardware:

Sliding windows use rollers and tracks → higher hardware cost
Casement windows need heavy-duty hinges
