Aluminium brand comparison

Aluprof, Reynaers, Cortizo, Aliplast, Decalu or Sheerline?

The best aluminium brand depends on the opening, not a league table. Compare the exact window, slider or bifold system, then keep glass, finish, hardware and fitting consistent. This page shows where each range starts; the project quote confirms the final product.

Short comparisons

Start with the decision that changes the project

Reynaers vs Aluprof

Reynaers is the architect-led premium route with UK support in Birmingham. Aluprof offers a broad architectural family at import pricing. Compare MasterLine 8 with MB-86N, then MasterPatio or Hi-Finity with MB-77 HS on the same elevation.

Cortizo vs Aliplast

Cortizo leads when a minimal visible frame and panoramic glass are central. Aliplast is the value-premium route, with Ultraglide correctly belonging to Aliplast rather than Reynaers.

Sheerline vs import brands

Sheerline gives a British-made counterpoint from the East Midlands. Compare its confirmed window and door specification with the imported systems rather than treating country of manufacture as a quality score.
