I've got a workshop with no heater or AC (I'm in North Florida, so I
don't NEED either), with fairly heavy shade year round. Would
insulating the walls do anything useful? Currently it's exposed studs
with T1-11 exterior and windows on 3 sides, with a sloped roof going
from around 10 feet down to 8'1/2" or so.
My Father in law keeps insisting I insulate the place, but I don't see
the utility, since there is nothing inside the workshop for the
insulation to work on. Would it pretty much only make the workshop
hotter in the summer and warmer in the winter, or would I actually be
able to see a difference?
With some active participation, it can be very useful, e.g.:
during cool part of day, let air in at one end & exhaust with fan at
once outside temp up to inside temp, close all ventilation until
Scheme works very well with large part of house.
It will help, but not make a major difference. When the sun is hitting full
strength, it will temper the heat rise from radiation, but not help the hot
air coming in the door or windows. In the cooler weather, if everything is
closed up, your body heat and heat from lights and motors will be retained a
bit more. A couple of degrees, but not 15 or 20.
I have a similar setup here in New England and insulated last year. In
winter I run heat at times and it helps considerably. In summer, it helps
slightly, not a major factor.
FWIW My shop is in a loft over a garage just north of Philadelphia.
It is heavily insulated so I can heat it in the winter. Without any
heat or air conditioning and with the windows shut its temp stabilizes
at about the average of the day plus the night temperature. 90 day and
70 night means about 80 in the next afternoon. For the winter with
lights and motors the insulation makes it comfortable. For a long warm
summer I work there in the mornings.
