Secondary glazing for Reading’s listed and roadside homes
Between the M4 corridor, the A329(M) approach and the mainline trains running through the town centre, Reading generates a steady demand for serious noise reduction on homes where the original sash cannot be replaced. Secondary glazing is the option Reading Borough Council conservation officers usually accept on listed and Article 4 street elevations, and Legacy Windows matches you with three specialists who quote a fixed price on the same brief.
Why locals in Reading choose Legacy Windows
- Typical 2026 pricing runs from around £390 for a small horizontal slider to £1,065 for a full-height vertical unit calibrated to Reading’s Thames Valley trade rates.
- Slim aluminium frames install inside the original reveal, meaning no visible change from the street and, in most cases, no Listed Building Consent required.
- Acoustic laminated glass options cut motorway and rail noise by up to 45 dB, tested to BS EN ISO 10140.
- Thermal performance on a retained single-glazed sash improves from around 4.8 to 1.8 W/m2K, meeting Part L for retained fabric.
- All matched fitters carry public liability insurance and a workmanship warranty of at least ten years.

Frequently asked questions
Does secondary glazing suit a Caversham Article 4 property? Yes. Reading Borough Council conservation officers routinely favour secondary glazing on Article 4 streets in Caversham because the original sash is left in place and the elevation looks unchanged from the pavement.
How much noise reduction can I expect from the mainline? A 100 to 150 mm cavity with a 6 mm acoustic laminated inner pane typically cuts around 40 to 45 dB. Homes on Vastern Road or close to the station approach commonly specify the deeper 150 mm cavity for maximum reduction.
Can secondary glazing be reversed? Yes. Aluminium secondary units are fitted to the surrounding reveal, not the original sash, and remove without damage to the original frame or plasterwork.
