The Benefits of Investing in Secondary Glazing
While the upfront cost can be considerable, the return on investment (ROI) is realized through improved convenience and lower energy expenses.
Substantial Heat Retention
Secondary glazing can reduce heat loss through windows by approximately 60%. By developing an additional barrier, it eliminates drafts and keeps the internal surface area of the window warmer, which considerably minimizes the demand on central heating systems.
Superior Noise Reduction
For homes near hectic roadways, airports, or railway lines, secondary glazing is frequently more efficient than standard double glazing. When set up with a space of 100mm to 150mm from the main window, it can decrease external sound levels by as much as 80% (approximately 50 decibels).
