Replacing old windows with Salamander double glazing — complete apartment renovation guide Bucharest 2026

When is the right time to replace your windows?

7 clear signals that your windows need replacing:

• Condensation between glass panes — the thermal glass seal has failed. Cannot be repaired — must be replaced.
• Draughts with windows closed — seals have worn. Temporary fix possible, but replacement is more economical after 15+ years.
• High energy bills in winter — old windows can account for 30–40% of heat losses. Old Uw 2.8 W/m²K vs modern Uw 1.0 W/m²K = nearly 3× more heat lost.
• Excessive street noise — old windows: 20–25 dB. Modern Salamander: 38–47 dB.
• Difficulty opening/closing — repeated hardware repairs cost more than replacement.
• Yellowed or cracked profiles — old PVC without UV stabilisers degrades in 10–15 years.
• General renovation — best time for new windows is during renovation when walls are already exposed.

Real savings from replacing windows

For a 60 m² Bucharest apartment with old windows:

• Heat losses through windows: ~35% of total
• Heating cost reduction after BluEvolution 92 + Low-E + nZEB installation: 65–75%
• Annual estimated saving: 280–500 EUR
• Payback period: 6–10 years

Which Salamander profile for renovation?

GreenEvolution 76 — best value for standard renovations. Uw 0.73, up to 42 dB, 76 mm depth fits existing openings without structural changes.

BluEvolution 92 — high standard. Uw 0.70 (double Low-E) or 0.55 (triple). Up to 47 dB acoustic insulation.

BluEvolution 92 ALU — premium aesthetics. Aluminium appearance with PVC performance. Any RAL colour without yellowing risk.

Common mistakes to avoid

• Choosing by lowest price — cheap profiles cost more over 30 years
• Not checking hardware brand — insist on Roto or Siegenia
• Installation without Blaugelb Triotherm+ precasings — eliminates 30–40% of thermal performance
• Not ordering sills at the same time — costs 40–60% more when ordered separately later
• Ignoring glass type — glass is 70% of the window surface; always request Low-E with argon
