Paul,unless you could borrow Stephen Burts father in law I strongly
recommend saving your pennies and buy a shop made screen !,
Some 30 years ago I made one from one of those selfconstruct (destruct)
kits,and whilst that was not too onerous,it took a bleedin' year to paint !
..
144 louvers, 3/4 coats, all to be hand held, on laid against something,
I've still got the paint marks on the patio to prove it .......

Has anyone here tried this?

I've been surfing in vain for louvered panels, so wondered if anyone has
any tips they could pass on?

It's not that difficult to build a Stevenson screen. You need
reasonable woodworking skills

Ah...

and a fair amount of time. The raw
materials will set you back around £200 though, and there's the stand
on top of that, so the newer plastic screens are not as expensive as
they seem (and of course they'll need no maintenance).

I guess I'll have to stick to my mini-screen for now - even though it
over-reads significantly in sunny summer weather (which isn't much of an
issue this year...)

Based on around 4 years observations, the average difference in maxima
ranges from only about 0.3C in mid-winter, to 2.7C in mid-summer.

I've noticed no seasonal variation in minima readings, though.
