Is it Time for New Windows
Your windows can lose their efficiency over time, so it’s wise to check that the seals between the glass, frames and rough openings are intact. To do so, hold a candle flame near the edges while your air conditioning unit blower is off. If the candle flickers noticeably, it could indicate a draft that needs proper insulation – or a crack that needs repair in order to prevent further loss of expensive “conditioned” air. Other problems that may indicate you need new windows include moisture-damaged or rotted frames, condensation or fogging between double glazed panels, rattling or sticky operation, and poor noise filtering.
