An external venetian when you want the garden
Updated
Tilted external slats can cut a large share of the sun and leave the garden visible. They will not lock the house and they hate being left down in a gale.
What the glass admits
The worked opening for An external venetian when you want the garden is 1.2 m wide by 2.1 m high, 2.52 square metres of glass. This figure puts 545 watts per square metre on the pane and uses a g-value of 0.7, about 961 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 144 watts and keeps about 817 watts out. That is a noon figure for comparison. An internal blind does not get the same reduction. For An external venetian when you want the garden, 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 hot part of the day
If the brief is 'cool, but we eat looking outside', start here rather than with a solid roller.
Dusk in January
Winter figure for An external venetian when you want the garden: glass at 1.4 W/m2K, 2.52 square metres, a 12 degree inside-outside gap and eight night hours. The bare pane is about 0.34 kWh a night on that crude sum. A closed shutter cutting about 24 percent of the flow leaves 0.26 kWh and saves about 0.08 kWh a night, only while it is down. Open it when you want winter sun.
Leave it if
Stop An external venetian when you want the garden if the door is an escape route and the motor has no way to open when it is dead. A photograph is not a manufacturing size.
Nottingham is only a setting for An external venetian when you want the garden. The streets there are not the product.
How to use the figure
The 1.2 by 2.1 metre opening inside An external venetian when you want the garden 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 £1,963. 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 An external venetian when you want the garden, 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. An external venetian when you want the garden covers one kind of opening. The house may have three.
When I would not order yet
An external venetian when you want the garden 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 An external venetian when you want the garden 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. £1,963 illustrates An external venetian when you want the garden for a 1.2 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 2.52 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 An external venetian when you want the garden 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. An external venetian when you want the garden uses a wired motor in the example so you can see how much the motor choice moves £1,963.
