 Insulated Bamboo Homes
Insulation R-Value requirements vary by climate. Here is the US DOE map of insulation zones in the USA from mild (6) to severe (1) climate zones. For mild climates, choose insulation up to R-19 for roofs and R-11 for walls. For severe climates, choose insulation R-30 for roofs and R-19 for walls. For bamboo homes, the customer determines the R-Values desired and chooses the insulation options. Contact BT about insulation options. Our technician works with your local contractor to determine estimated cost for the house and R-value of your choice.

Insulated roof panel (showing metal roofing on plywood substrate).
 Plywood substrate can be used for any direct applied roofing (asphault, wood or composite shingles). Wood nailing strips are an alternative to plywood substrate for all other roofing options. Insulation can be any thickness or R-Value. Insulation, substrate and roofing material are purchased and installed by owner/contractor on site.

Insulating bamboo house wall panels on site - 3 options.
1. Most economical: Fill interior side of the wall panel with foam or sprayed insulation and then apply sheetrock or imperial plaster to the inner side of the bamboo frame.
2. Mid-range: Remove the exterior bamboo siding and expose the wall cavity that can be filled with insulation, leaving interior bamboo poles exposed.
3. High-end: Apply exterior insulation to outside panel of plywood, then apply stucco or siding.
