Do you know how to install vinyl sliding over styrofoam board

[@Okuninushi-p1e]

I love your attention to detail Shannon. Others would be lazy an not have cut that lip.

[@Carpenters_Canvas]

I just finished a job like this yesterday lol . I took off this guys siding and installed thorax and foam then replaced the siding ..so I was watching this utube video , not this one but another , and this guy says you don’t need to install tyvek or thorax lol , homeowners beware of contractors who claim you don’t need house wrap . It is almost more important than the siding itself

[@jeffd3147]

I dont know much about wrapping. But do people put this stuff over top the older built homes ie bungalows that have those stucco? how would you layer it for old houses with stucco on the exterior? in example do people put paper down--> wooden frame---> styrfoam insulation---> plastic siding? I'm a total noob any ALL OF THIS STUFF. Looking to learn more before getting a friend to do this in the near future on my dads house. maybe in 2-3 years from now. I also live in Alberta Canada so it can go down to Negative -40 degree C which is -104 F

[@Carpenters_Canvas]

@@jeffd3147 if your going to go over stucco you need to put wooden cleats on the building kinda like studs on the side of the house that you can then mail the siding to , obviously there is a lot of other things you need to do in preparation . That’s only if you don’t want to just rip off the stucco

[@mrdouglasbaker]

Chill dude. Good teacher vibes.

[@VintageTexas59]

Looks good, nice with the house wrap behind it first for any water issues.

[@ducebigalow8834]

Some window manufacturers (Vinylguard in Canada) have a extended brick mould that allows for up to 2" insulation. This sets the actual thermal glass into the wall and not on the exterior of the wall. They also have optional jamb extensions for the inside allowing it to be flush with drywall.

[@gerilehner1797]

Thanks for the tip ducebigalow.

[@pensive69]

Really good and professional work . Around our area in W PA we have enough rain and moisture to contend with that we suggest to the architect/homeowners the have us cover the house sill. I didn't see that done in the video segment but sealing at the bottom helps water drain without touching the lumber surface.

[@gerilehner1797]

@pensive69 do you have links to share on how covering the house sill is done. Thanks in advance for any info

[@shanemccauley8354]

You might mention the spray foam should be minimal expanding from or it can blow the rigid foam off of the house. Just a thought I'm sure you have put it around doors and windows starting out and seized them fast. Just another thought a video on the different types of foam might be helpful for all of us. Love the content of your video thanks for taking your time to educate us.

[@cityscene121]

I'm glad you posted this video because it spoke to my concerns. I agree, the best way was to go with the house wrap first. The other way is going to be met with balloons forming and you racing around trying to secure the wrap. Thanks , great video

You can add flashing around existing windows that extended window frame to thickness of finished wall. That requires custom bending.

[@blindtomdiy5918]

You could use 3 inch decking screws with a fender washer on them to hold down the foam board. Do you worry about having to vapor barriers the foam board being one and faced fiberglass insulation on the interior of the house? Wouldn’t that trap moisture?

[@Willdoe09]

I was wondering the same thing. Have you looked in to it ?

[@ulrichkessler9328]

You are one of my favorite channels to follow for home improvement projects. I'm actually running into the similar situation, i have 1" rigid foam and building up 1" buck around the opening where we can install window (nailing fin) on the top it looks like perfect solution, this way the foam will be flush with the fin. The only question is when reviewing the code and installation instructions it says: "Embedment must be a minimum of 1 1/4" into the structural framing" So is the 1" buck counts as the "framing" since technically it is 'outside' of the wall framing? My window depth is 3.25" that leaves 2.25 before the fin minus the sheeting 0.75" which leaves 1.5" embedded into the frame (2x4) If we build the buck 1" out, that will technically leave the window only 0.5" inside the frame (2x4)

[@HouseImprovements]

Yup you are fine.

[@HouseImprovements]

I install vinyl siding all the time over up to 2" thick rigid foam insulation. I use 3" shingle nails. For 1-1/2" styrofoam I would use 2-1/2" nails. Some other sidings restrict the thickness of insulation under them to 1" max. An example would be cement board siding

[@mikekeating]

It's my understanding that the house wrap goes at the same depth of your windows. His windows are installed on the ply wood, so wrap gets installed on ply wood. If the windows were built out to match the insulation, the wrap should be installed on the installation.

[@Kashype101]

Can you do this In a cylinder block house? Cause my house has no insulation on it

[@maxv7668]

Is any chance mold can appear between foam board and home wrap? As I see there is no gap for venting. What do you think?

[@bcoldwell1]

I had the same question. You now have a vapor barrier inside behind you gyp, on the warm side, and with the xps, you have added another vapor barrier. Kind of possible to "trap" any vapor moving from warm to cold. There is - I have heard - a rule of thumb about what % of you R value can be outside the housewrap, vs on the warm side. I'm doing the same as done here, so need to figure it out. Roxul is vapor permeable, so isn't an issue I don't think.

[@Faruk651]

This is why it is not a good idea to use XPS foam (like the one used in this video) on the exterior side of the house. Instead you should be using EPS styrofoam. Because eps foam will not trap vapor.

[@Faruk651]

There are EPS styrofoam sheets that has channels on the back side which helps air movement and ventilation. Durock has Puccs Styroams as an example.

[@darren234r23d]

Generally its recommended that the house wrap selected should include drainage plane.

Taping the house wrap to the bottom window trim is probably a bad idea. If there is a leak around the trim, it will funnel water right to the sheathing. But then that's probably the best you can do without taking the windows and redoing the sill pan.

[@puppyna]

After the house is wrapped do you need the foam before putting the siding?

[@HouseImprovements]

You dont need to add foam, its only if you want to add insulation value.

[@johnschutt9187]

So, if you're going to cut out for the window extension, why not do that when you're putting up the foam insulation? Why cut twice? Doesn't that also risk cutting your air seal? Thanks.

Vinyl siding in cold temps is not fun you are correct. The corners I used are 1 premade corner piece but you can buy the same product in individual 1x4 or 1x6 also. Just like I used around the windows. These are made by Smart Trim but there are other similar products also. You could also cut the old siding just around the corner far enough to install a premade corner. Just tuck your house wrap around teh corner and under the old siding if possible.

[@amandajohnson2850]

[@joe_matt]

Shouldn't all the wood used at the bottom of the house and the electrical unit be treated wood?

[@HouseImprovements]

No not really, it is not in contact with the ground and really should not get wet often and if it does should easily dry out. If you use treated wood then be sure your nails/screws are ok to use with treated lumber and you would have to use copper or some kind of vinyl at the electrical service because metal or aluminum should not be in contact with PT wood. You could use metal or aluminum if you used a membrane or maybe even house wrap between the PT and metal.

Hi Shannon, I have a question, Im putting up LP osb panel siding and removing old masonite. The walls have foil covered 5/8" insulation board nailed to the studs that are insulated with fiberglass batts. Of course the interior walls have a plastic barrier finished with sheetrock. Does the plastic barrier on the interior serve as an adequate vapor barrier with the foil covered insulation board?

Im getting ready to start on another wall and considering replacing the 5/8" insulation board with the 2" that you used in this video. Thanks

Also, if I use the blue tapcon screws to attach the styrofoam to the wall - they may rust, but will they rust under the siding?

Often I see this type of exterior foam insulation project come together nicely but when it’s time to install stucco or vinyl siding over it, seems to become a “ok now what?” Type of scenario. Also there’s usually other fixtures such as mailboxes and lighting etc that need to be adjusted to accommodate the foam. I’ve heard it recommended in another video to install the foam over the studs then osb / plywood on top of that so you have a substrate to fasten siding to. Just doesn’t seem to be a good way to do this overall. Wish there was a system out there that made sense.

Hi Shannon! Do you tape house wrap AND the rigid foam insulation? Should blue tuck tape be used now? From Edmonton!

Hello It's really great work, however I couldn't understand how you did the corners. Did you bent the styrofoam, the nail it and added the half inch wood on top of it. Thank you

The corners I installed a strip of 1-1/2" foam up each side of the corners then I covered that with a strip of 1/2" plywood . Then i butted 2" foam to those and filled in the rest of the wall surface. The 1/2" plywood on the corners makes applying nails easier for trims and corners.
