EIFS
gets
hot
I am in some need of information about Stucco. I
built a
new house
and my contractor convinced me to use stucco. He
said that there is a
new
product out, sort of like a synthetic stucco
(perhaps it was
synthetic).
I watched them apply this. First they put on a 1 or
1.25 inch of foam
insulation
and then a net mesh, and then about a 1/4" of mud or
whatever it is
called.
As far as looks goes, it looks great. The problem I
am encountering is
heat.
Here in the Midwest we have had 95 degree weather
for the last
2
weeks.
Well, using an infrared heat gun I went around the
house at
9:00
AM with an outside temperature of about 85 degrees.
Here are some of
the
readings I got.
Concrete walk = 82
Roof (elk) = 95
Stucco = 145 to 151 degrees!
The outside of the house was too hot to touch. Yes
it was
in direct
sunlight, but why would the temperature increase to
over 150
degrees?
Have you heard of this before?
This is synthetic stucco, commonly known as EIFS.
I have heard that it gets real hot. If it gets so hot,
I don't see where it has much insulation value in the
summer.
EIFS brags about a high R factor, but has very poor
thermal mass,
probably the worst of any material.
