Removing old shingles to vinyl side again

This is my second time vinyl siding the same house. The first time it came out so bad the company was a complete rip off. I have lived with it for 15 years but now its time for new siding and I want it done right. I am thinking I want to remove the old shingles and then have the house completely ply-wooded with 1/2 inch board then the foam insulation and then the tyveck is that how it goes? I want to know before I talk to the siding company's, so I know what I'm talking about. I really want to insulate the house as it is a very cold climate here.
Also what do you think of the insulated vinyl siding?
Has anyone used it? Can it be used with the foam insulation?

Studs, sheathing, house wrap, foam insulation, siding in that order.

There is a precaution many folks forget or are not aware of when using house wrap on older houses---those build before the mid 1900's.

Many of those houses had little planning for moving fresh air into and stale air out of the structure, other than the normal leakage by windows/doors/etc. When such a house is wrapped, there is no way to get air movement and the house air becomes stagnant and can cause sick building problems.

It is easy enough to add an air exchanger to a central air unit to prevent that from happening.

I installed a lot of vinyl siding in years past, but would look at the newer siding products now on the market. Vinyl would not be my first or second choice today in a cold climate.

Cement board(Hardi products is one brand) is durable in cold weather. And there are steel siding and faux stone products available.

I have a house now with a combination of insulated steel lap siding and insulated faux cedar shake shingle plastic siding. Zero maintenance(except washing) and the siding is several decades old.

you'll get more value with the foam sheathing
installed on the walls vs insulated vinyl siding.
the foam sheating is continous and in direct
contact with the walls. tape all seams, seal
any holes.

insulated vinyl siding isn't in direct contact
and does little to add insulation value.

I too perfer hardi to vinyl. just don't like
the looks of vinyl.

houses are leakier than you think. we make
walls fairly tight, but it is the holes in
the ceilings to attic that are the main
contributors to air leakage.

if you are worried have a blower door test
to determine air changes per hour.
below .30 air changes requires fresh air
per ashrae 62.2 standare.

in existing homes we hardly ever have to
add fresh air. new construction..is a different
story.

best of luck
