The myth that every UK house can wear a German shutter
Updated
German streets were often built with the box in the wall or with a tolerance for the look. British streets of sash windows and conservation areas were not.
A pane, so the rule has a house
The worked opening for The myth that every UK house can wear a German shutter is 1.8 m wide by 2.1 m high, 3.78 square metres of glass. This figure puts 495 watts per square metre on the pane and uses a g-value of 0.7, about 1310 watts into the room if the curtain is up. An opaque external shutter, taken as stopping 85 percent of that gain while it is fully down, leaves about 197 watts and keeps about 1113 watts out. That is a noon figure for comparison. An internal blind does not get the same reduction. For The myth that every UK house can wear a German shutter, use the noon figure to compare two openings on the same house, then let a measured survey replace the figure.
An internal blind does not get that reduction, because the energy has already crossed the glass.
The rule without the fog
Rear extensions can take the idea. Polite fronts often cannot. Copy the principle, not the postcard.
Winter and permission are different files
Winter figure for The myth that every UK house can wear a German shutter: glass at 1.4 W/m2K, 3.78 square metres, a 12 degree inside-outside gap and eight night hours. The bare pane is about 0.51 kWh a night on that crude sum. A closed shutter cutting about 24 percent of the flow leaves 0.39 kWh and saves about 0.12 kWh a night, only while it is down. Open it when you want winter sun.
What I would do before paying
Stop The myth that every UK house can wear a German shutter if the solar panel would sit in a soffit with no sky, and the quote has no wired alternative. A photograph is not a manufacturing size.
Exeter is only a setting for The myth that every UK house can wear a German shutter. The streets there are not the product.
How to use the figure
The 1.8 by 2.1 metre opening inside The myth that every UK house can wear a German shutter is there so a quote has something to disagree with. If the tape gives a different size, the tape wins.
The example drive is a wired motor, and the illustration is £2,510. A belt, a wired motor and a solar motor can share a curtain and still be different jobs. Compare those lines, not a single bold total.
What the survey still has to write down
For The myth that every UK house can wear a German shutter, ask where the box lands, what colour reference will be ordered, and how the curtain opens when the motor is dead. Those three answers move the job more than a rounded price.
Leave the lantern, the side light and the next elevation off the order unless they are drawn. The myth that every UK house can wear a German shutter covers one kind of opening. The house may have three.
When I would not order yet
The myth that every UK house can wear a German shutter should wait if the opening is an escape door with no way to raise a dead motor, or if the front is the elevation a conservation area was drawn to protect.
A photograph is not a manufacturing size. Two quotes for The myth that every UK house can wear a German shutter only compare when the slat, the box and the drive are the same kind of thing.
Questions worth asking the fitter
Is the price on this page a quote?
No. £2,510 illustrates The myth that every UK house can wear a German shutter for a 1.8 by 2.1 metre opening with a wired motor, at September 2026 rates. Your survey replaces it.
Does the shutter cover every pane?
It covers the opening it is built for. Here that example is 3.78 square metres. A roof lantern, a side light or the next elevation is another line.
What if planning is unclear?
Do not pay the factory for The myth that every UK house can wear a German shutter until a listed building, a conservation front, a flat or a shopfront has a written answer. Ordinary rear walls on houses are sometimes simpler.
What should two quotes share?
The same openings, the same slat type, and the same drive. The myth that every UK house can wear a German shutter uses a wired motor in the example so you can see how much the motor choice moves £2,510.
