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.
About Us
Glass sides turn a louvred pergola into a room you can use from March to November. The three infill options, the Building Regulations exemptions that apply, the condition that breaks them, and the glass the rules require.
Which aluminium and steel-look systems suit Wimbledon's Victorian, Edwardian and inter-war houses, what Merton's conservation areas and Article 4 direction actually change, the Part L U-value limits, and sixteen real SW19 installs.
A louvred pergola gives adjustable shelter, a fixed-roof veranda gives permanent cover, and a glass room makes an enclosed extra room. How the three differ on planning permission, building regulations, spans, drainage and winter use.
