Secondary Glazing Salisbury
Salisbury is defined by its history, from the medieval Chequers and the prestigious Cathedral Close to the Georgian townhouses of St Ann Street. But for those living in these beautiful properties, modern comfort often feels out of reach. Single-glazed sash windows, while aesthetically essential, are poor at keeping out the noise of the ring road or the winter chill.
For owners of Grade II listed buildings in Salisbury and Wilton, replacing these windows is rarely an option due to strict Article 4 directions and conservation rules.
KJM Group offers the perfect compromise. Our discreet secondary glazing is designed to sit virtually invisibly behind your existing windows. It drastically improves thermal efficiency and acoustic performance without disturbing the historic fabric of your home—making it a solution that conservation officers (and your heating bills) will appreciate.
Why Salisbury Homes Need Secondary Glazing
- Conservation Safe: A reversible adaptation ideal for Salisbury’s listed buildings.
- Noise Reduction: Blocks up to 80% of noise—essential for homes near the A36 or City Centre.
- Warmer Rooms: Stops draughts instantly and improves thermal retention by over 60%.
- Discreet Design: Slimline frames match your existing window sightlines perfectly.
The Heritage Solution
Protecting Salisbury’s Architectural Legacy
Salisbury is unique in its density of Grade I and II listed buildings. From the timber-framed structures near the Market Place to the Georgian townhouses on the outskirts of the Close, preserving the external appearance is non-negotiable.
Our Slimline Secondary Glazing is the ideal solution for properties under strict Article 4 directions. Because the units are installed comfortably within the window reveal and do not replace the original timber, they are considered a reversible adaptation. This is a crucial distinction for Wiltshire Council conservation officers, who generally view secondary glazing as a permitted improvement where double glazing would be rejected.
We offer bespoke solutions for every style found in the city, including Vertical Sliders for Georgian sash windows and discreet Lift-Out units for smaller medieval cottage windows, ensuring the character of your home remains untouched.
Sound proofing
Acoustic Performance
Silence the Ring Road Noise
For many Salisbury residents, particularly those living near the A36 Ring Road (Churchill Way) or busy streets like Exeter Street and Castle Street, traffic noise is a constant intrusion. Single-glazed windows simply vibrate with the sound, letting it pass straight into your living room.
Secondary glazing is the most effective retrofit solution for noise reduction. By installing the secondary pane with a gap of 100mm to 200mm from your primary window, we create a “decoupling” effect that breaks sound waves.
When specified with our 6.4mm Stadia Silence acoustic glass, this system can reduce external noise by up to 80% (54dB). It turns a property on a busy Salisbury main road into a quiet, calm sanctuary.
Keep the heat in
Thermal Efficiency
Banishing Draughts in Older Homes
Many of Salisbury’s historic properties suffer from “sash rattle” and significant heat loss. As timber frames age, gaps appear that allow warm air to escape and cold winter draughts to rush in.
Our secondary glazing units are precision-measured to seal your window opening completely. Using twin brush seals, they clamp tight against the sub-frame to create an airtight barrier. This eliminates draughts instantly and can reduce heat loss through the window aperture by over 60%.
This added layer of insulation also helps tackle condensation, a common issue in Salisbury’s older housing stock. By keeping the inner glass warm, it prevents moisture from settling on the cold outer pane, protecting your original timber sills from damp and rot.

Secondary Glazing FAQ's
Do I need planning permission for secondary glazing in Salisbury?
In the vast majority of cases, no. Because secondary glazing is installed on the inside of the room and does not alter the external fabric of the building, it is generally considered a “reversible adaptation.” This makes it one of the few improvements accepted by Wiltshire Council conservation officers for Grade II listed buildings without requiring full planning permission, though we always recommend checking first.
Will secondary glazing block the traffic noise from the A36 Ring Road?
Yes, it is exceptional for noise reduction. By installing the secondary unit with a 100mm to 200mm gap from your original window and using our specialist acoustic glass (Stadia Silence), we can reduce external noise by up to 80% (54dB). This makes a massive difference for properties near Churchill Way, Exeter Street, or the train station.
Is secondary glazing suitable for the medieval properties in the City Centre?
Absolutely. We understand that many Salisbury properties, particularly in the Chequers, have unique, non-standard window shapes. We offer bespoke solutions, including horizontal sliders for York sash windows and lift-out panels for smaller cottage windows, ensuring the character of your medieval timber framing is preserved.
Will it help with condensation on my timber sills?
Condensation is a major issue in Salisbury’s older housing stock. Secondary glazing creates a sealed internal barrier that prevents warm, moist air from your home hitting the cold single glazing. This significantly reduces moisture buildup, protecting your original timber sills from black mould and rot.
Do you install in villages outside Salisbury?
Yes. Our installation team covers the entire Salisbury area and the Nadder/Chalke Valleys. We regularly work in Wilton, Alderbury, Downton, and Amesbury. We are fully familiar with the mix of thatched cottages and Georgian homes found in these surrounding villages.
