Magnetic Tape for Secondary Glazing – Thermal & Noise Insulation Solution

Upgrade your windows with an easy-fit magnetic secondary glazing system – perfect for improving insulation, reducing noise, and boosting energy efficiency without permanent changes. This cost-effective DIY solution is ideal for listed buildings, rental properties, or any home where full window replacement isn't feasible.

How It Works
This system includes two tapes:
Magnetic Tape – Applied to the acrylic sheet
Steel Tape – Applied to the window frame

Once installed, the magnetic bond holds the acrylic in place securely while remaining fully removable when needed.
