Installing new siding and windows. Will be direct replacing some windows but also reframing some as we will be installing bigger windows. Also will be installing new sliding glass door where there is nothing now.

Should the new windows, doors be installed once the siding is removed then the new siding goes back on once the window/door install is complete? Looking for correct sequence, thanks.

Yes windows and doors are always first. Any thought about foam board behind siding? What kind of siding?

Funny was just watching some videos on the house wrap. So we are going to pull off all the old siding and see what's underneath. Thinking we will replace whatever wrap and/or foam boards are there depending on the condition.
Should you always have the foam board installed? I know the house wrap for sure but wasn't sure if that foam board on top of wrap is critical. Thanks.

BTW, I'd assume we'd have to remove some of the siding if we are installing bigger windows and doors that weren't there before. And if we are re-wrapping the house doesn't that go in after we frame window/doors opening but before window/door install? Thanks.

Foam board is a good way to had insulation thickness to the walls with out loosing space inside. But adding something somewhere to 2x4 wall is a good idea when you have a chance. Adding to the outside does change how you install windows.


When you prep the window you just leave it in a way that the rest of the house wrap can be added later.



This video is almost what we do here. A few details have been changed since this was made.

And if you are using a solid surface siding you want air behind it like this.

I heartily second the rain screen. It makes a lot of sense. The siding will only prevent so much water from getting through, and house wrap will do the same.

And foam board, even a 1/2 inch will help keep the heat where you want it.

Thanks a lot. So all vinyl siding should have those furring strips underneath and not installed directly to a completely flat surface?

So just for clarity what are the materials/layers under vinyl siding?
1. Sheathing
2. House wrap( either tar paper or tyveck type.
3. Foam board(optional)
4. Furring strips for the vinyl siding.

No vinyl siding has so many holes for air movement the air gap is not needed. The thing to remember is that any siding is for weather and sun the house wrap or tar paper is what keeps the water out. :vs_cool:

Got it, thanks.

If you watched the video on the window prep. the idea is that all windows will leak sooner or later so we catch the water or condensation and give it a path out.

In the video he wrapped the tar paper in the bottom and the top.

we don't do the top as if water is coming down the wall we want it to get in the window cavity

We put the lower one just blew the window and just put the blueskin on the sill and now they want a 1x4 just at the back that meats the window to block water from coming in.

You rough openings should be round numbers in 2" increments and the windows should come 1/2 smaller than you order. We set the window on 1/4" plastic spacers and put 1/8 horseshoe spacers behind the bottom flange to let the water out.
