The Benefits of Investing in Secondary Glazing
While the upfront cost can be substantial, the roi (ROI) is realized through improved convenience and lower energy expenses.
Substantial Heat Retention
Secondary glazing can decrease heat loss through windows by as much as 60%. By creating an additional barrier, it gets rid of drafts and keeps the internal surface area of the window warmer, which considerably minimizes the demand on main heating systems.
