isolation in my r4

[vlk]

Hy,

I have a litle problem, When it' s cold outside, my car very slowly heating
inside the car...

I was thinking to put an isolation in my car. I was looking to put on cars doors, and car roof.

What type of isolation can i use?
I'm worried about condensation in my car? Is this a problem (for rust)?
Thanks for your help, and I am sorry if my english is not so good...

Big greetings from slovenia

heat

flush out heater(they can get badly clogged on old cars)check that thermostat is not sticking open,if ok see if renault do a hotter/winter thermostat.if conditions are very cold +5 or colder fit cover to front of radiator to reduce air flow(renault make one,if you make your own don't cover too much)
hope that helps theres nothing worse than a car with no heater in the winter
