We select the optimal system for each application — Cortizo, Smart Systems, and Aluprof — rather than pushing a single manufacturer's range.
Direct Trade Windows fabricates every aluminium frame in-house at our Slough workshop — cutting, drainage milling, crimping, and assembly run on Fom Industrie machinery under one roof in Berkshire.
System-agnostic across Cortizo, Smart Systems, and Aluprof, we specify the optimal system for each project — whether that's Cortizo COR Vision for ultra-slim sliding doors, Smart Visofold for bi-folds, or Alitherm Heritage for steel-look heritage replacements.
