If you ask me between Temperature and Humidity, which is more important. My answer is Temperature. We need to maintenance the temperature between 26degC to 30degC all the time in our BH. So selecting proper insulator is very important during the initial BH setup.
If your BH is at the corner or standalone, the source of the heat is from the wall and roof. For Shop lot, the heat source mainly from the roof.
Few type of insulator:-
1.) Styrofoam - My current BH used 2" Styrofoam place on top of ceiling. There is a aluminum foil right below the roof. With this combination, my BH temperature highest point is 31degC.
2. Heat Insulator Paint - Some one in the Swiftlet Product Forum recommend this as it can bring down the heat at the roof > 5degC. The price for 20 liter is about RM680. But you need to apply a layer of "Primer" for better adhesive which is around RM600++. You can use this on your wall. http://www.kingkote.com/tiki-index.php
3. Cellulose - Some one in the "Swiftlet Product Forum" also recommend this. http://www.tclmalaysia.com/
4. Rockwool - I use this one for my new BH because my friend recommend this to me and the price also quite reasonable. Each pack consist of 6pcs Slab (1200x600x50mm) and cost about RM52. For 20x70 feet shop lot, I bough 30 packs and cost me around ~RM1600.
