Description

Using sliced wood - plyfilm instead of plastic on construction sites and in buildings. Use Woodbreath as a breathing insulation layer in buildings; as a semi-transparent breathing wall/window material; as a filter material in passivhouse heat exchange system; to pack and shelter wood constructions, depending on wood species (value) and according glue (waterproof or biodegradable). It doesn't exclude using Woodbreath in other fields as medicine, filtering, music or crafts. It's traditional veneer and plywood in new form (plyfilm): from 2-ply film less than 0,15 mm up to a normal thin (airplain) plywood. Minimal veneer thickness depends on wood cell properties: eg juniper ca 0,035 mm, pine 0,05 mm, alder and willow 0,07 mm, aspen 0,11 mm. Slicing machine patent by Nakataro Mochizuki (1970-ties), now free.

Material list

Raw wood, manual slicer or industrial slicing machine, sharpening tools,
(if plywood will be formed) additional glueing table or line, drying room are needed.
More efficient machines and adhesives need to be developed.

Ecological values

Raw material doesn't need drying. Low value bush species can be used: alder, willow, aspen etc can be used. Sliced film is drying in seconds to hours, depending on thickness. Productive, sparing. Lightweight. No dust. Minimal waste. Biodegradable. Strong - reusable. Surface is smooth, glossy. Beautiful. Consumes 5-6 times less machinepower than traditional horizontal slicer or peeler. Machines are about 5-6 times lighter than traditional ones - less steel tons are used. Even wooden machine parts may be considered. May be handled manually (on site).
