The Benefits of Investing in Secondary Glazing
While the upfront expense can be considerable, the roi (ROI) is recognized through improved comfort and lower utility expenses.
Considerable Heat Retention
Secondary glazing can decrease heat loss through windows by approximately 60%. By developing an additional barrier, it gets rid of drafts and keeps the internal surface area of the window warmer, which substantially decreases the demand on main heating systems.
Superior Noise Reduction
For residential or commercial properties near busy roads, airports, or train lines, secondary glazing is frequently more effective than basic double glazing. When installed with a space of 100mm to 150mm from the primary window, it can lower external noise levels by as much as 80% (approximately 50 decibels).
Conservation of Heritage
For owners of heritage properties, secondary glazing is often the only accepted method of updating windows. It is typically thought about a “reversible” modification, meaning it does not harm the material of a listed building, hence keeping the property's market value.
