Secondary Glazing For Tiverton's Listed Buildings And Conservation Properties
Secondary glazing fits a separate inner panel - aluminium-framed, clear glass - on the room side of the existing window. It doesn't replace the original window, doesn't alter the external appearance and is generally considered a reversible internal alteration that doesn't need planning permission. For Tiverton's conservation area and listed building properties, this matters significantly.
Tiverton has conservation areas covering the town centre and some historic streets. The town also has a large stock of 1960s and 1970s properties with original metal-framed single-glazed windows - these are a common replacement job and generally straightforward permitted development. We confirm your planning position at the survey. Secondary glazing bypasses these constraints entirely - it's the route Exeter City Council and East Devon consistently recommend for properties where the original windows are to be retained.
Beyond the planning advantages, secondary glazing delivers real performance improvements. A well-fitted unit with an 80-100mm air gap can reduce a single-glazed window's U-value from around 5.0 to below 2.0 W/m²K. For noise reduction it often outperforms conventional double glazing - the larger air gap between the original glass and the secondary panel cuts traffic noise more effectively than the 16-20mm cavity in a sealed double-glazed unit. For properties on Gold Street, Westexe, Fairfax Road and Phoenix Lane, that acoustic benefit is often as valued as the thermal improvement.

Secondary Glazing Options We Fit In Tiverton
Horizontal Sliding Secondary Glazing
Horizontal sliding panels open to give full ventilation and access to the original window for cleaning. The most popular secondary glazing type for living rooms and bedrooms where you want to be able to open the window in summer without removing a fixed panel.
Lift-Out Secondary Glazing
Fixed panels that can be lifted out completely for summer ventilation or cleaning. Simpler and slightly lower cost than sliding units - a good option where the window is accessed less frequently or where the room is mainly heated rather than ventilated.
Fixed Secondary Glazing
Permanently fixed panels for maximum thermal and acoustic performance. Best used in rooms where ventilation through that window isn't needed - utility rooms, north-facing rooms, or where you have other ventilation available. Gives the best U-value of any secondary glazing system.
Acoustic Secondary Glazing
Acoustic secondary glazing uses a larger air gap (typically 100-150mm) and may incorporate laminated glass to maximise sound reduction. The larger gap delivers better noise reduction than a conventional double-glazed unit. For properties near busy roads or train lines, this is the most effective solution available.
What Secondary Glazing Delivers For Tiverton Properties
Planning-compliant solution
Secondary glazing is the approach planning officers consistently recommend for conservation area and listed building properties. It's reversible, doesn't alter the original window and is generally considered permitted development.
Significant thermal improvement
A well-fitted secondary unit with a 100mm air gap can reduce the U-value of a single-glazed window from around 5.0 to below 2.0 W/m²K. In Devon's winters, the improvement in room temperature on the cold side of the house is noticeable immediately after fitting.
Better noise reduction than double glazing
The large air gap in secondary glazing (80-150mm) is more effective for noise reduction than the narrow gap in a conventional double-glazed unit. For properties near busy roads, this is often the better acoustic solution.
Original windows preserved
The original window is untouched and its character preserved. For historic properties, this isn't just a planning requirement - it's the right approach architecturally. Secondary glazing is genuinely reversible.
Reduces condensation
Secondary glazing keeps the inner face of the original window warmer, which substantially reduces condensation. In Devon's damp winters, condensation on original single-glazed windows is a persistent problem that secondary glazing addresses effectively.
Cost-effective
Secondary glazing typically costs £300-£600 per window - less than a full replacement in many cases. For a property with many windows, the cumulative saving over full replacement can be significant.

Our Guarantee
Every window and door we install is backed by a 10-year workmanship guarantee. That covers the fitting itself - how the frame sits in the opening, how it's sealed, how the hardware operates. If anything we've done causes a problem within ten years, we come back and fix it.
The glazing units themselves also carry a 10-year manufacturer's guarantee against seal failure and condensation between the panes. Both guarantees are issued in writing on completion of the job, alongside your FENSA certificate. When you come to sell, your solicitor will ask for these documents - we make sure you have everything you need.
The guarantee only stands if the product is correctly installed. That's why we don't rush surveys, we don't cut corners on preparation, and we don't send crews who don't know what they're doing. The guarantee is only as good as the quality of the work behind it.

What Tiverton Customers Say
Genuine feedback from homeowners across Exeter and the surrounding area
"Had all eight windows replaced in our 1970s house in Heavitree. The team arrived on time, laid dust sheets throughout and were done in two days. Biggest difference is the warmth - no more draught across the living room floor in January. Really happy with the whole job."
Karen T. — Heavitree, Exeter
"I got three quotes. These were the only company who actually came out and measured properly before pricing - the others just asked for the number of windows and gave me a number over the phone. The price was competitive and the job was done cleanly. Would use again without hesitation."
Mark R. — Topsham
"Secondary glazing fitted throughout our listed cottage near the Cathedral Close. They knew the planning restrictions before I'd even finished explaining and recommended exactly the right product. The noise reduction from the road is noticeable immediately. Brilliant from start to finish."
Sarah M. — St Leonard's, Exeter
"Composite front door replaced after the old one warped and stopped sealing properly. The new door is solid, the fitting is neat and they took the old door away. Got our FENSA certificate in the post a few days later. Exactly what you want - no fuss, job done."
David H. — Pinhoe, Exeter
"Bi-fold doors fitted to the rear of our extension in St Thomas. The difference to the kitchen is incredible - it feels like a completely different room when they're open onto the garden. The team were tidy, professional and explained everything clearly throughout. Top marks."
Claire W. — St Thomas, Exeter

Do I need planning permission for secondary glazing in Tiverton?
Secondary glazing is generally considered a reversible internal alteration and does not normally require planning permission, even on listed buildings. This is precisely why it is the approved approach for Tiverton's conservation area and listed building properties where full window replacement is not permitted. We recommend confirming with the local planning authority before ordering if you have any doubt about your specific property.
Will secondary glazing work on sash windows in Tiverton?
Yes - secondary glazing is well-suited to sash windows, which are common in Tiverton's older properties. Horizontal sliding secondary panels work well behind sash windows - the inner panel slides in the same direction as the sash, so you can still open the original window by sliding the secondary panel first. For listed buildings and conservation area properties where the original sash is to be kept, secondary glazing is the standard recommended approach.
How much thermal improvement does secondary glazing give in Tiverton?
A well-fitted secondary glazing unit with an 80-100mm air gap can bring a single-glazed window's U-value from around 5.0 down to 1.8-2.0 W/m²K - within reasonable range of a standard double-glazed unit. In Tiverton's winters, the improvement in room temperature on the cold side of the house is noticeable immediately after fitting.
How long does secondary glazing installation take in Tiverton?
A single room typically takes half a day. A full house installation is usually completed in one day. Secondary glazing is less disruptive than full window replacement - there's no external scaffolding, no removal of existing frames and no exterior sealant work. We work through each room in turn and leave each one clean and finished before moving on.
