Question:
I have a small woodworking shop using half of my two car garage. Years ago
I put a wall between the two garage doors and have now got the interior
wall, two outside walls and ceiling properly insulated. I have 2 major questions.
1. What is the best (and economical) way to insulate the inside of the
garage door? I don't want to permanently seal it, but probably haven't had
an occasion to open it for the past 5 years.
2. What should I look for in choosing an individual air-conditioning unit
for this type of installation? I will have 220V service available at the
enclosed end of the shop and plan to mount the unit through a dedicated
opening about 6 or 7 foot off the floor in that end of the shop.
Answer:
try using some foam panels,they can be set into the framing members of
a metal door Is the roof insulated? If not stuff all the insulation
you can up there (R30, even R11 is better than nothing. You've got to
kill that radiant heat.
Look for about 400 sq. ft. per ton. This is a little bit heavy, but
should help out. above all, get some insulation on the roof, then the
south and west walls!
Mitsubishi makes a neat little 2 pc unit, 1 1/2T with a condenser unit
outside about the size of a briefcase, and an indoor unit that can
either wall mount or ceiling mount. A bit spendy, but they work great
in a shop up to 500 sq. ft. or so
