Museum had to be given slats for ventilation (7)

Ross

I believe the answer is:

louvred

I'm a little stuck... Click here to teach me more about this clue!

'slats for ventilation' is the definition.
I can't tell whether this defines the answer.

'museum had to be given' is the wordplay.
'museum' becomes 'louvre' (art museum in Paris).
'had' becomes 'd' (in contractions e.g. 'I'd', 'you'd' etc).
'to be given' says to put letters next to each other.
'louvre'+'d'='LOUVRED'

Can you help me to learn more?

(Other definitions for louvred that I've seen before include "Like some doors" , "provided with overlapping slats" , "(Of a shutter) slatted" .)

I've seen this clue in The Sunday Times and The Times.
