which is the best insulation to use for under vinyl ciding? its cold here in canada .
i was told star foam 1" and also to use firestone 3/4 thick whats your take on this? thanks vern
The insulation board that many siding companies advertise and install is more hype than anything. What the board does help with is to give a more uniform look when installing vinyl over another product such as wood siding.
The R-factor that this board provides will make very little signifcant difference.
You would be better to have an insulation contractor look at your house to find out where the heat loss is coming from and address those issues.
Dont get me wrong, Im not saying that you shouldn't put it on there if it is needed for uniformity but it is hype,
just like Tyvek and products like it.......a 30 # roll of felt is 10 x better than these building papers that are installed all the time....same with insulation....find out where the heat loss is...and address it at the point.
re insulation for vinal siding ,o forgot to tell you
that this insulation would be going over stuco exterior wall of course. whisc insulation is the best for this? thanks
Tyvek is not accept in most counties where I build as a moisture resistant barrier when dealing with masonry products.........30# felt is accepted.
There were several studies done when this stuff first came out show that it was not as effective as it was claimed.
Since then Tyvek may have made some changes to their product .................but when I ask myself is this product really needed in light construction.................to me the asnwer is no.
I personally turn by osb backward, slick side out as an additional barrier versus putting up the Tyvek.
Houses need to breath.......including veneers.
It is important that the brick mason maintains the required
gap, one inch, between the brick and the exterior sheating on that wall. This helps create an air gap that in itself will allow moisture to excape through wee holes.
I think house wrap is more hype then anything else.
A person can forego the Tyvek and save several hundred dollars.
Dependining on the size of the house, and instead put that money in a better form of insulation such as cellulose...............which you will get your money out monthly in lower heating and cooling bills.
