Are you considering extending your home with a veranda? The choice of material is crucial for the durability, aesthetics and thermal performance of your extension. In this article, we compare aluminum and PVC verandas in detail to help you make the best choice.

Aluminum veranda: elegance and performance

Aluminum is the premium material for modern verandas. It offers unmatched slim profiling, maximizing glass surface and natural light intake. Its natural corrosion resistance makes it ideal for the Belgian climate.

  • Slim profiles for maximum light
  • No maintenance required
  • Lifespan exceeding 40 years
  • Wide choice of RAL colors
  • Excellent thermal insulation with thermal break

PVC veranda: economical and insulating

PVC remains a popular choice due to its excellent value for money. It's a naturally insulating material that offers good thermal performance. However, its thicker profiles reduce glass surface compared to aluminum.

  • Lower entry price
  • Good natural thermal insulation
  • Easy maintenance with soapy water
  • Wider profiles, less light
  • More limited color choice

Thermal performance comparison

Thermal insulation is an essential criterion in Belgium. Modern aluminum verandas with thermal break now achieve equivalent or even superior performance to PVC. The choice of glazing (double or triple) has more impact than the structure material.

  • Aluminum with thermal break: Uw 1.2 to 1.5
  • Standard PVC: Uw 1.3 to 1.6
  • Triple glazing recommended for both
  • Importance of air tightness
  • EPC certificate for your extension

Our recommendation

At Archi Construction & Veranda, we recommend aluminum for most projects. Although the initial investment is slightly higher, the durability, aesthetics and value appreciation of your property more than compensate for this difference. PVC remains interesting for tighter budgets.
