Heat, so the price has a job
The worked opening for Will a shutter stop a burglar? is 1.5 m wide by 1.2 m high, 1.8 square metres of glass. This figure puts 520 watts per square metre on the pane and uses a g-value of 0.63, about 590 watts into the room if the curtain is up. An opaque external shutter, taken as stopping 80 percent of that gain while it is fully down, leaves about 118 watts and keeps about 472 watts out. That is a noon figure for comparison. An internal blind does not get the same reduction. For Will a shutter stop a burglar?, use the noon figure to compare two openings on the same house, then let a measured survey replace the figure.
Winter on the same opening
Winter figure for Will a shutter stop a burglar?: glass at 1.2 W/m2K, 1.8 square metres, a 12 degree inside-outside gap and eight night hours.

Open it when you want winter sun.
