The Benefits of Investing in Secondary Glazing
While the in advance cost can be substantial, the roi (ROI) is recognized through enhanced convenience and lower utility bills.
Significant Heat Retention
Secondary glazing can decrease heat loss through windows by up to 60%. By developing an additional barrier, it gets rid of drafts and keeps the internal surface of the window warmer, which significantly minimizes the need on central heating unit.
Superior Noise Reduction
For properties near hectic roadways, airports, or railway lines, secondary glazing is typically more reliable than basic double glazing. When set up with a gap of 100mm to 150mm from the primary window, it can minimize external sound levels by as much as 80% (approximately 50 decibels).
