Window in a house from 1955 - double-glazed, triple-glazed???

Hello everyone,
I have bought a mid-terrace house from 1955 that urgently needs new windows.
In total, it is about ``only`` 7 windows plus windows in dormers that still have to be built.
(3 x 1050x1330, 2x1800X1600, 2x balcony doors 1030X2200)

The house is not insulated from the inside or outside and will not be.
What would you recommend for windows here (wood, plastic) and what should be considered? Double or triple glazing? Special frames?

And last but not least: What kind of price including dismantling and months should we roughly expect here?

Many thanks and best regards!

We know too little about your house. In 1955, I suspect monolithic walls of 25 cm solid brick, but that is only speculation. Do the jambs still have stops? During dismantling, a lot can be damaged. The most important thing, in my opinion, is that the installer is competent. Let him also procure the windows.
