How Energy Efficient Are Aluminium Windows?

Choosing the right windows for your project—whether you’re a homeowner, installer, or developer—can dramatically impact performance, aesthetics, and long-term value. When considering aluminium windows vs wooden windows, which is the better fit?

Wooden Windows: Classic Appeal

Wooden windows offer timeless charm, often favoured for heritage homes or conservation areas. However, they come with a few drawbacks:

  • Regular Maintenance: Timber frames require ongoing care—sanding, painting, and sealing—to protect against moisture and UV damage.
  • Durability Concerns: Wood is prone to rot, warping, and swelling, especially in damp or exposed environments.
  • Energy Efficiency: While wood is a natural insulator, movement in the frame can lead to draughts and reduced thermal performance.
  • Security Limitations: Older wooden windows may lack modern locking systems, making them more vulnerable to intrusion.
