- Can I see recent aluminium windows work near Desborough?

- What thermal performance does aluminium windows achieve in Desborough?

- When are aluminium windows the right choice?
- For contemporary properties, larger apertures and rear extensions, aluminium offers slimmer frames, more glass and a lifespan measured in decades. On smaller period cottages, uPVC or flush casements usually suit better; we advise honestly at survey.
- What colours are available?
- Any RAL. The most popular finishes are RAL 7016 (Anthracite Grey), RAL 9005 (Jet Black), RAL 7021 (Black Grey), RAL 9001 (Cream) and Bronze textures. Dual-colour (different inside/out) is available across the range.
- Do aluminium windows get cold or condensate?
- Modern aluminium uses a 34mm polyamide thermal break inside the frame which stops cold transfer. With warm-edge spacer bars and A-rated glazing, condensation and cold-frame feel are eliminated — performance rivals uPVC.
