Plantation louvres and heat
Updated
Louvres inside the room are a joinery product for privacy and for shaping daylight. The sun has already entered.
What you are actually choosing
They can make a hot room feel even stiller. If the customer says 'shutters' and the room is a glazed extension, ask which problem they mean before you measure for hinges.
A roller, a screen, a venetian and a plantation panel are four answers.
An illustration, not a winner
The worked opening for Plantation louvres and heat is 3.2 m wide by 1.5 m high, 4.8 square metres of glass. This figure puts 570 watts per square metre on the pane and uses a g-value of 0.7, about 1915 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 287 watts and keeps about 1628 watts out. That is a noon figure for comparison. An internal blind does not get the same reduction. For Plantation louvres and heat, use the noon figure to compare two openings on the same house, then let a measured survey replace the figure.
Fitted illustration for Plantation louvres and heat in Reading: £3,774 at September 2026 prices, for this 3.2 by 1.5 m opening with a wired motor. The figure allows a front-mounted aluminium curtain and ordinary fixing. It does not include scaffold, a rebuilt soffit, planning drawings, or a new window. A second opening on the same visit usually costs less than the first, because the van is already there. Compare two quotes only when the slat, the box and the drive match.
Winter does not care about the brochure
Winter figure for Plantation louvres and heat: glass at 1.4 W/m2K, 4.8 square metres, a 12 degree inside-outside gap and eight night hours. The bare pane is about 0.65 kWh a night on that crude sum. A closed shutter cutting about 24 percent of the flow leaves 0.49 kWh and saves about 0.15 kWh a night, only while it is down. Open it when you want winter sun.
A poor reason to mix them
Stop Plantation louvres and heat 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.
If Plantation louvres and heat is really a privacy job on a bay, price internal louvres and stop forcing a cassette to do joinery.
How to use the figure
The 3.2 by 1.5 metre opening inside Plantation louvres and heat 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 £3,774. 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 Plantation louvres and heat, 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. Plantation louvres and heat covers one kind of opening. The house may have three.
When I would not order yet
Plantation louvres and heat 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 Plantation louvres and heat 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. £3,774 illustrates Plantation louvres and heat for a 3.2 by 1.5 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 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 Plantation louvres and heat 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. Plantation louvres and heat uses a wired motor in the example so you can see how much the motor choice moves £3,774.
