Winter sun you might want to keep
Updated
Low winter sun on a south window is free heat and free morale. A shutter used with a summer timetable will throw that away.
When the curtain has to be down
In December, many houses should have the curtains up by day and down at dusk. The motor is useful because that routine is too boring to do with a stiff belt every night, and still worth doing.
A size you can argue with
The worked opening for Winter sun you might want to keep is 3.2 m wide by 1.5 m high, 4.8 square metres of glass. This figure puts 470 watts per square metre on the pane and uses a g-value of 0.76, about 1715 watts into the room if the curtain is up. An opaque external shutter, taken as stopping 90 percent of that gain while it is fully down, leaves about 171 watts and keeps about 1544 watts out. That is a noon figure for comparison. An internal blind does not get the same reduction. For Winter sun you might want to keep, 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 night cover
Winter figure for Winter sun you might want to keep: glass at 2.6 W/m2K, 4.8 square metres, a 12 degree inside-outside gap and eight night hours. The bare pane is about 1.20 kWh a night on that crude sum. A closed shutter cutting about 30 percent of the flow leaves 0.84 kWh and saves about 0.36 kWh a night, only while it is down. Open it when you want winter sun.
A bad reason to proceed
Stop Winter sun you might want to keep if the only place for the box is a listed street front and nobody has written advice from the council. A photograph is not a manufacturing size.
Norwich is only a setting for Winter sun you might want to keep. The streets there are not the product.
How to use the figure
The 3.2 by 1.5 metre opening inside Winter sun you might want to keep 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 solar motor, and the illustration is £3,908. 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 Winter sun you might want to keep, 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. Winter sun you might want to keep covers one kind of opening. The house may have three.
When I would not order yet
Winter sun you might want to keep 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 Winter sun you might want to keep 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. £3,908 illustrates Winter sun you might want to keep for a 3.2 by 1.5 metre opening with a solar 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 4.8 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 Winter sun you might want to keep 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. Winter sun you might want to keep uses a solar motor in the example so you can see how much the motor choice moves £3,908.
