Replace old aluminium windows if they have no thermal break, misted glazed units, failed seals or frames that no longer close securely. If the frames are sound and only the glass or hardware has aged, repair or re-glazing can be enough and keeps the original slim look.
When is replacement the right call?
- Cold frames with constant condensation, typical of older frames without a thermal break
- Single glazing or early double glazing that loses heat
- Corroded or warped frames and failed seals
- Poor security from outdated locks
When can old aluminium windows stay?
Where the frames are straight, undamaged and the finish is intact, new glazed units and fresh hardware can improve performance without full replacement. Check that the existing frame can take a modern, thicker unit.
What changes with modern aluminium windows?
Current frames include thermal breaks, warm-edge glazing and multipoint locking, so the comfort, noise and security gains over 1970s to 1990s aluminium are substantial. Replacement glazing in homes must also meet Building Regulations, which an installer registered with a competent person scheme can self-certify.
Whether to replace or repair depends on frame condition and the glazing, so it is worth having the frames inspected first. Wednesfield Trade Windows is a family-run, Certass registered firm that fits aluminium windows.
