No, that isn't the way insulation works. It simply slows heat
transfer from hot to cold. If the house is cooler than the outside,
the insulation is HELPING keep the house cool.<br>

<div>In addition to the 30 degC-plus outdoor temps in summer,
there are still the internal heat gains due to occupancy and
solar gains from the S/W-facing glazing which are no doubt
appreciated in winter but it's not the job of the insulation to
get rid of that same heat in summer when it's not welcome.</div>

<br>
True, but the insulation's job is to keep the 30+ outside from
getting in. Which it is. Unless internal heat gains raise the
inside higher than the outside temp, the house should be cooler with
insulation than before.<br>

<div>That job falls to stuff like shading devices , ventilation
strategies, thermal mass etc. ... and I would not under-estimate
the role that significant amounts thermal mass can play in
helping to provide large temperature differentials between
inside and outside.</div>
</blockquote>
<br>
Thermal mass does nothing to provide large temperature differentials
between inside and outside. All it does is require large amounts
of heat to change temperature. Whether you want more or less is a
complicated question based on climate and other factors.<br>
