Secondary Glazing for Listed Buildings in Conservation Areas in Scotland

Living in a period property or a listed building is a privilege, but it often comes with a cold reality: original single-glazed windows are draughty, thermally inefficient, and loud. Because traditional double glazing is often rejected by local planning authorities due to its impact on the building’s exterior, homeowners are left searching for a high-performance alternative.

Why Secondary Glazing is the Preferred Heritage Solution

Unlike replacement windows, EcoShield Secondary Glazing is a fully “reversible” internal addition. It requires no structural changes to the building’s fabric and is virtually invisible from the street.

• Planning-Friendly: Because it sits discreetly on the internal side of your existing windows, it rarely requires Planning Permission or Listed Building Consent.

• Aesthetic Integrity: Our ultra-slim aluminum profiles are powder-coated to match your existing frames exactly, ensuring the historic sightlines of your sash or casement windows remain untouched.

• Condensation Control: Heritage homes often suffer from dampness. Our system provides managed ventilation to help eliminate condensation on original timber frames, protecting them for the future.
