A Perfect Solution for Heritage Properties
Older buildings present a particular challenge. Single-glazed sash windows, leaded lights, and original timber frames are often the very details that give a property its value and charm. Yet they can also be the source of significant heat loss, draughts, and discomfort.
Flutter Shutter™ takes a more respectful approach, improving thermal performance from the inside while leaving your windows untouched. The result is a warmer, more efficient home that retains its authentic character.
How Flutter Shutter™ Works in Heritage Settings
The system has been designed with conservation in mind.
Here is what that means in practice.
Internal Installation
Flutter Shutter™ fits entirely on the inside of your windows. The transparent thermal roller blind sits close to the glass, while the plantation shutter adds a refined second layer.
There is no need to remove, alter, or disturb the existing window in any way. Installation is clean, contained, and carried out from within the room.
No Change to External Appearance
Because the system is internal, the view from the street stays exactly as it should.
Original frames, glass, and detailing remain on full display from the outside. For properties where external appearance is closely protected, this is a significant advantage.
Suitable for Conservation Areas
Within conservation areas, alterations to a building’s external character are tightly controlled.
As Flutter Shutter™ makes no changes to the exterior of your property, it offers a practical way to improve energy efficiency without compromising the qualities that define the area.
Suitable for Listed Buildings, Subject to Approvals
Additional regulations protect listed buildings, and any work should be carefully considered. Because Flutter Shutter™ is reversible and does not alter the historic fabric of the windows, it is well-suited to listed properties.
We always recommend confirming the necessary consents with your local conservation officer before installation, and our team can support you through that conversation.
Preserve Architectural Heritage
The architectural value of a period property lies in its detail. Original glazing bars, hand-blown glass, and timber joinery tell the story of a building and cannot be replaced once lost.
Flutter Shutter™ protects that heritage by working alongside your windows rather than against them.
The plantation shutter brings a clean, timeless finish that complements period interiors, while the existing windows remain fully intact behind it.
You improve comfort and efficiency without surrendering a single original feature.
Improve Thermal Performance
Heat escapes most readily through glazing, and historic windows are particularly vulnerable. Flutter Shutter™ addresses this directly.
The transparent thermal roller blind traps a layer of insulating air between the glass and the blind, slowing the transfer of heat from inside to out.
Combined with the plantation shutter, this forms an effective thermal barrier that delivers performance comparable to triple glazing.
The benefit is a stronger EPC rating and savings of up to £200 per year on energy bills*, achieved without replacing your existing windows.
Reduce Condensation
Condensation is a common and persistent problem in older properties. When warm internal air meets cold single-glazed windows, moisture forms on the glass, which, over time, can damage timber frames, decorations, and soft furnishings.
By keeping the inner surface warmer and reducing direct contact between warm air and cold glass, Flutter Shutter™ helps to manage condensation. This protects both the window and the surrounding fabric of your property, supporting the long-term preservation you care about.
Increase Comfort
Comfort in a heritage home is about more than temperature alone. Cold spots near the glass, persistent draughts, and uneven warmth all affect how a room feels through the day.
Flutter Shutter™ creates a barrier between your living space and the window, reducing draughts and steadying the temperature throughout each room.
Your home feels warmer in winter and more controlled in summer, with the quiet, refined comfort that period properties so often lack.
A More Practical Choice Than Window Replacement
For heritage properties in particular, the advantages over full window replacement are considerable.
-
Lower disruption.
Installation takes place internally and is contained within the room, with no removal of original windows and no external works. Your home remains liveable throughout.
-
Lower cost.
Avoiding full window replacement removes one of the most significant expenses associated with retrofitting an older property, while still delivering modern thermal performance.
-
Faster installation.
Because there is no need to remove or rebuild existing windows, the process is considerably quicker, getting you to a warmer, more efficient home sooner.
