: I have a framework of two by twos suspended about seven ft high
: above the strong back area. The frame is about 23 ft long by
: about 8 ft wide. Over this I have taped one and a half meter
: wide lengths of bubble wrap. They form a ceiling above the boat
: and hang down to the floor. The strips are taped up with packing
: tape to keep the whole thing fairly airtight.

: The bubble wrap gives good insulation and let's good light through.
: I made the tent as low and small as possible while still giving
: enough room to move around in, so that the space to heat is
: small.

: When the heat gets up the roof and walls, which are weighed down
: with long planks, bulge outward.

: I use two electric radiator heaters to get the temps up, then when
: I start to glass I just turn the thermostat switches on the
: heaters till the light just clicks off and I know I won't get
: outgassing.

: When I don't need the heat I lift up the sides and throw them onto
: the top of the frame. Don't even know it is there.

I've got a very similar set up using 6 mil poly. I ran two lengths of bailing wire the length of the shop for the roof frame. I've got two pairs of heat lamps that clamp to the strongback frame.
